D63CF03CC36CFFF88CFDFAF60C02F864.taxon	discussion	Remarks Numerous living specimens from 0.4 to 1.7 mm of a Lepetella species were found at depths of 1706 m (V 2) and 1720 m (V 10), attached to the external surface of empty tubes of the onuphid polychaete Hyalinoecia tubicola (Müller, 1776), which is common on deepest (1470 ‒ 1809 m) sedimentary bottoms of the GB (Serrano et al. 2017 a). Dantart & Luque (1994), Lima et al. (2015) and Hoffman et al. (2019 b) have described some new species of Lepetella in different areas of the Atlantic, and the latter authors mention the possible presence of the dubious taxon L. ionica Nordsieck, 1973 in the GB. Nevertheless, a comparative anatomical and molecular study of these deep-water specimens and specimens of N Atlantic shallower water species of Lepetella is necessary to ascertain if they belong to a different and perhaps undescribed species.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

D63CF03CC36AFFFE8C02FDB70D67FA40.taxon	discussion	Remarks Three living specimens (3.5, 3.4 and 2.0 mm) were found on the inside surface of an empty egg-capsule of the smalleyed rabbitfish, Hydrolagus affinis (de Brito Capello, 1868) (Holochephali, Chimaeridae). Two specimens (3.5 and 2.0 mm) were attached close to small oval thinner areas or holes on the wall of the egg-capsule (Fig. 3 I) caused by limpet rasping during feeding (Dantart & Luque 1994). The shell and the external morphology of the living specimens resemble those of A. excentrica from shallower depths, but given their small size, further anatomical and molecular study is needed to identify them with certainty. As far as we know, this is the deepest record (1683 m) for living specimens of any Addisonia species. Living specimens of Addisonia excentrica were found down to 330 ‒ 426 m in the Mediterranean (Dantart & Luque 1994). The NW Atlantic Addisonia paradoxa (Dall, 1882), synonymized with A. excentrica by Dantart & Luque (1994), was found alive by Dall (1882) from 110 to 293 m, and McLean (1985) recorded it from 119 to 1170 m, deepest records being probably shells. Addisonia enodis Simone, 1996, described from Brazil, was recorded alive down to 184 m (Simone 1996; Lima et al. 2016) and the NE Pacific A. brophyi McLean, 1985 from 155 to 174 m depth. Besides, this is the first record of an Addisonia species living inside a holocephalan egg-capsule. In addition to two empty eggcapsules (only one of them with Addisonia), three specimens (2 females and one male) of Hydrolagus affinis were caught in the same sample (Bañón et al. 2016).	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

D63CF03CC36BFFFD8C70FA510DDCFC9A.taxon	discussion	Remarks This species was never formally compared with Emarginula crassa Sowerby, 1813, described as a Pliocene fossil in the Crag of Ipswich (England) and reported in the Recent fauna of the British Isles and Scandinavia (Forbes & Hanley 1850: 481) and off NW Spain in 748 ‒ 1262 m (Dautzenberg & Fischer 1897: 179). The latter species is differentiated by having a lower profile, with the apex more central and less curved backwards, and in having a more attenuated sculpture. In our experience, it has never been possible to differentiate the two species in the same locality, therefore they could represent at most geographical variants or subspecies of the same taxon. In the fossil record, Marquet (1995) separated subspecies Emarginula crassa crassa from E. crassa crassalta Wood, 1874, which is very similar, if not identical, to E. christiaensi. However, both forms did not coincide in the same geological formation. More recently, Hoffman & Freiwald (2018) cited many empty shells of Emarginula christiaensi and two shells of E. crassa on the continental slope of Mauritania as if both were two different species, but they did not compare them and their figures do not show any differential character. The resolution of this taxonomic problem is beyond the scope of this work, but the name Emarginula crassalta Wood, 1874, would have priority if it were the same as Emarginula christiaensi.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

Pérez-Gándaras, Instituto de Investigaciones Pesqueras de Vigo-CSIC leg.; CER-MHNS. Description (based on material examined from GB) Shell small (length 4.0 mm, width 2.9 mm, height 3.9 mm), with an oval outline in apertural view, in lateral view with a conical profile, the apex located in the posterior ¼ and in the upper ⅓ of the shell, curved towards the ventral side. Protoconch of one whorl, rounded, skewed to the right side, with a diameter ca 245 μm (Fig. 5 E). Selenizone small but well marked, narrower than the foramen, bordered by a smooth and slightly raised rim. Foramen elongate, narrowing anteriorly to a sharp point, located dorsally in the highest part of the shell, bordered on each side by a flange that continues that of the selenizone; width of the foramen 9 % of the width of the shell; length 30 % of the length of the shell. In front of the foramen, there is a double rib along which the two halves of the shell meet. Sculpture almost absent in the initial coiled part, then mainly constituted by small pustules, aligned along a median thread to form radial cords (Fig. 5 F). The width of the interspaces between radial cords is equivalent to or somewhat greater than the thickness of the pustules, and the interval between pustules along a cord is less than the diameter of the pustules. In the abapical half of the shell, appear additional radial cords that grow rapidly in thickness until the primary cords are matched. There are around 80 ‒ 90 radial cords reaching the growth edge of the shell, of which one-third was added in the abapical half. The pustules are also connected by fine, irregular commarginal lamellae. Aperture oval, contained in a plane, with its edge denticulated by the termination of the cords. Inner surface smooth, shiny, with a groove running from the foramen to the anterior edge. Large internal septum (one third of the total length of the shell), with sharp and almost straight anterior edge, concealing more than half of the foramen in apertural view.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

D63CF03CC369FFC18C68FC4E0B37FC87.taxon	distribution	Distribution The type locality of Puncturella agger is Challenger station 24, off north of Culebra Island, Puerto Rico. It was subsequently recorded from Florida, Cuba and Mexico by Pérez Farfante (1947). Living specimens and shells are known from NW Galicia and Galicia Bank, shells only from Meteor, Hyères, Irving, Plato, Atlantis and Josephine seamounts (Corral Prado 2006, as Cranopsis sp.; Barrio González 2015, as Cranopsis agger (Watson, 1883 )), and shells recorded as Rimula granulata Seguenza, 1863, from Ampère, Seine and Sedlo seamounts (Beck et al. 2006) and Rockall Bank (Hoffman et al. 2011 a), see under remarks. The species has therefore an amphiatlantic distribution.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

D63CF03CC369FFC18C68FC4E0B37FC87.taxon	discussion	Remarks This species has been reported from different locations in the northeast Atlantic with names which we consider wrong. Rolán Mosquera & Pérez-Gándaras (1981: 6, pl. 1 fig. 4) and Rolán Mosquera (1983: 68) recorded and illustrated for the first time one specimen from the Galicia Bank, misidentified as Puncturella profundi Jeffreys, 1877, which is a different species currently named Profundisepta profundi (Jeffreys, 1877), (see Fig. 6 E – G herein). The specimen figured in the aforementioned papers is illustrated again here (Fig. 5 M – N). The shell figured by Micali & Villari (1989: figs 1 ‒ 4) as Rimula granulata Seguenza, 1863, from the Pleistocene of Salice (Sicily) is somewhat similar to P. agger, but clearly differs in having an extremely inflated profile, with an apex much more anterior and much more curved towards the ventral edge so as to be situated near the half of the total height of the shell (in the upper third in Puncturella agger). The sculpture of this fossil species is also different, with the radial rows of tubercles all of similar size and thicker than the spaces between rows. An old shell, possibly subfossil, collected from the Galicia Bank (Fig. 4 K ‒ L) could represent the real Puncturella granulata, since it agrees in profile and sculpture with the original description and illustration of Rimula granulata by Seguenza (1863: 88, figs 6, 6 a). Watson (1883: 31) reported and described a specimen of “ Puncturella (Cranopsis) granulata, Seg. [tuberculata n. sp.] ”, also collected in the type locality of Puncturella agger (Challenger Sta. 24). However, it is not clear whether this identification is correct since Watson’s (1886: 46, pl. 4 fig. 5) illustration is a copy of Seguenza’s (1863: fig. 6) and he described his specimen as “ peculiarly long and narrow ” which does not fit the original description. This identification was nevertheless assumed by Pérez Farfante (1947: 125 ‒ 126, pl. 54 figs 4 ‒ 7) who also considered that Puncturella watsoni Dall, 1889 was the same as P. (C.) granulata sensu Watson (1883, 1886). Puncturella watsoni is also very close to the Western Atlantic Puncturella larva Dall, 1927 (see Pérez Farfante 1947). Further specimens of Puncturella agger from SEAMOUNT 1 DW 116 were recorded in Eva Corral’s unpublished undergraduate project (Corral Prado 2006) as Cranopsis sp. Later, Lucia Barrio in her PhD Thesis (Barrio González 2015) described and illustrated as Cranopsis agger (Watson, 1883) a large amount of material (32 specimens and 362 shells) collected in several cruises from different localities of NW Galicia and several NE Atlantic seamounts (see under distribution). Puncturella fornicata Locard, 1898, a valid species never reported since its original description from off Western Sahara, 782 m (Locard 1898: 78 ‒ 79, pl. 5 figs 1 ‒ 3), is somewhat similar to P. granulata in profile but with definite radial ribs as in P. asturiana and P. noachina. None of the eight western Atlantic species of Cranopsis described and illustrated by Simone & Cunha (2014) is identical to Puncturella agger. Cranopsis canopa Simone & Cunha, 2014 is somewhat similar in profile and in having a relatively small septum, but it differs from P. agger in having fewer and broader axial ribs (46 versus up to 90 in P. agger), uniform axial ribs (P. agger usually has larger and smaller ribs intercalated), and the ventro-anterior edge of the septum concave, while in P. agger it is convex.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

D63CF03CC355FFC58FD2F9650CE3FE0C.taxon	discussion	Remarks Ortega & Gofas (2019) used this name for the Anatoma species which is common at depths less than 1000 meters in the Canary Islands, and concluded that the synonymy with Scissurella tenuis Jeffreys, 1877 proposed by Geiger (2012) was not warranted. The latter, with an abyssal type locality in the northwest Atlantic, differs by the configuration of the early whorls and the habitat. Anatoma richardi, originally described from off the Azores Islands in 1360 m, is also found on GB. In A. richardi, the suture of the body whorl may be more or less detached from the selenizone of the previous whorl (the “ sutsel ” in Geiger 2012), whereas in A. tenuis the suture is reported as always adjusted to it. Anatoma tenuisculpta (Seguenza, 1880), described from the Pleistocene of southern Italy and recorded as living in the Alboran Sea and Ibero-Moroccan Gulf and in several localities off NW Europe (Høisaeter & Geiger 2011; Geiger 2012), also belongs to this species group but is distinguished by having a higher profile with the last whorl even more clearly separated from the selenizone. We have never seen any locality with A. richardi and A. tenuisculpta sympatric and separable, and the possibility that they represent morphological variation in a single species should be investigated. Some specimens from GB (Fig. 7 G – I), here reported as A. cf. richardi, are rather stunted with a rather wide sutsel, but could not be convincingly delimited from typical A. richardi.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

D63CF03CC351FFC88C2CFE090B64FAB3.taxon	description	Description Shell up to 3.3 mm high and 4.1 mm maximum diameter, with low conical spire, angulate periphery, moderately inflated base and a small umbilicus. Protoconch of ¾ whorl, about 240 µm in maximum diameter, terminated by a slightly flaring edge; protoconch sculpture of irregular granules which tend to form spiral lines towards the periphery. Teleoconch I (until the beginning of the selenizone) about 1.1 whorl, with about 45 ‒ 50 faint axial riblets, more indistinct in their adapical part, and with a distinct spiral thread abutting on the beginning of the selenizone. Teleoconch II with 2 to 2.5 whorls, separated by a deep suture, and the space between suture and selenizone (the “ sutsel ” according to Geiger 2012) somewhat wider than the latter. Marked peripheral keel, accentuated by the abapical edge of selenizone, which is more prominent than the adapical edge. Selenizone delimited by two narrow lamellae, inside with weakly marked growth stages. Adapical surface of whorls with axial riblets and very thin spiral threads; the riblets arched, much narrower than the interspaces, uneven and very irregularly spaced, attenuated upon reaching the selenizone, about 70 on the first whorl of teleoconch II, about 110 ‒ 120 on the last whorl; spiral threads, about 20 in the last half-whorl, attenuated in the part that borders the selenizone. Base regularly convex, with sculpture of axial riblets and spiral threads similar in density and appearance to those of the adapical part; the ribs are somewhat flexuous and prolonged inside the umbilicus; the spiral cords, about 35 ‒ 40, are somewhat weaker towards the periphery. Umbilicus small, without apparent funiculus. Aperture rounded, interrupted by an incision which extends on about ¼ of the last whorl and narrows at the edge. Colour white.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

D63CF03CC351FFC88C2CFE090B64FAB3.taxon	discussion	Remarks Anatoma corralae sp. nov. is most similar to A. schiottei Høisaeter & Geiger, 2011, described from the Norwegian Sea, and was mistaken for it in the preliminary report of INDEMARES BANGAL (Gofas et al. 2014 b). It differs in being larger (4 mm, compared to 2.25 mm in A. schiottei), having a longer teleoconch I (more than one whorl vs 0.75 whorl) with much more numerous axial riblets (50 vs 15), and in lacking a funiculus in the umbilicus (conspicuous in A. schiottei, see Høisaeter & Geiger 2011: fig. 48). Nevertheless, both species share the same angular outline, the microsculpture of the protoconch with granules tending to be aligned along spiral lines, and the shape of the edge of the protoconch, which is only slightly flaring and has no secondary thickening. The protoconch microsculpture, unusual in the genus, suggests that they may be related. Among the species locally present, Anatoma umbilicata, which is found together in the same hauls, differs clearly by its broad umbilicus and in being practically smooth. Anatoma tenuisculpta is quite similar to Anatoma corralae sp. nov. in size and outline, but differs in having a much coarser axial sculpture forming a regular lattice with small nodules at the intersections of riblets and spiral threads; it also has a much shorter teleoconch I, hardly over half a whorl. Anatoma richardi, which is found on GB but not in the same depth interval, also has such coarser sculpture, and its last whorl is more ample and its suture is not so far below the selenizone.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

D63CF03CC359FFCD8FE1FD3C0A4FFA00.taxon	discussion	Remarks This is, to our knowledge, the first time that this species is reported outside the Azores (Dautzenberg & Fischer 1896) and the South Azorean Seamount Chain (Hoffman et al. 2020 c). The external sculpture recalls that of Moelleria costulata (Møller, 1842), a boreal Atlantic species which belongs to the family Colloniidae Cossmann, 1917 and has a calcareous operculum fitting exactly the aperture; the flexuous contour of the aperture in the present species suggests that the operculum was flexible and that this similarity does not indicate reationship. For the time being, with no data on the living animal, there is no straightforward generic placement. Cyclostrema Marryat, 1819, a member of the family Liotiidae Gray, 1850 with also a calcareous operculum, is obviously inadequate and we conservatively use the catchall genus “ Skenea ”, in a broad sense meaning a skeneimorph species, following in that WoRMS Editorial Board (2021).	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

Protoconch of ¾ whorl, about 260 µm in maximum diameter, terminated by a simple, curved edge; protoconch sculpture of minute, irregularly spaced granules. Teleoconch with up to 3 convex whorls. First whorls sculptured by minute spiral threads, irregular in size and spacing, about half the size of interspaces; occasionally these threads are interrupted or anastomosing. The spiral threads become inconspicuous on the later whorls, persisting in the subsutural zone and within the umbilical area, but lacking in the median part of the body whorl, where only growth lines can be seen. Umbilicus narrow and deep, not delimited from the rest the whorl. Aperture evenly rounded except for a slight angle at the termination of the suture; outer lip very thin, slightly flexuous, slightly prosocline. Colour slightly yellowish on fresh shells, otherwise whitish.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

D63CF03CC359FFD08C1EF9E40C59FA5C.taxon	discussion	Remarks Species of Anekes are mostly characterized by a peculiar “ Anekes sculpture ” which consists of minute raised lines, anastomosing in a criss-cross pattern. In Anekes affinis (Jeffreys, 1883) this sculpture is spread over the entire surface and quite noticeable. Anekes sculpturata Warén, 1992 is similar but smaller (hardly exceeds 1 mm) and the microsculpture has a preferential orientation in the spiral direction, while in A. affinis it forms a non-directional network. In Anekes paucistriata Warén, 1992 the sculpture is evident only on the first whorl and may also occur in the umbilicus, but it is almost completely missing in intermediate surface and an attentive examination is required, under strong magnification and preferably under SEM, to detect it. This kind of sculpture is not exclusive of the genus Anekes, and it is also present on Granigyra inflata (Warén, 1992), originally described in Anekes but later (Warén 1996) found to have radular characters closer to Granigyra Dall, 1889. Anekes spiralis sp. nov. differs from the other species of Anekes in that the microsculpture is definitely spiral, not just with a preferential orientation like in A. sculpturata or in A. undulisculpta, but a limited anastomosing pattern occurs on some (especially the very early) parts of the shell of A. spiralis sp. nov., supporting the generic placement.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

The specimen illustrated here is larger and definitely adult, but has, like the holotype, a small mucronate protoconch, teleoconch whorls unusually convex for a eulimid, and a projecting profile of the outer lip, making this the closest match we could find among the species described from the area. This identification remains tentative, especially taking into account that the host holothurian species was not found in our material.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

D63CF03CC340FFDF8E8DF8800F4DFC1F.taxon	discussion	Remarks There are two species of Colus Röding, 1798 to be found on GB (Fig. 24), and their correct identification is crucial since they are an important component of the benthic community and food chain. Both have extremely similar shells and their accurate identification relies essentially on the diagnostic character of the protoconch. Colus gracilis is found on the summit platform and the adult is somewhat larger and more solid, whereas C. jeffreysianus has a broad distribution on the deeper part of the slope. Colus aurariae Fraussen, Rosado, Afonso & Monteiro, 2009, described from off Portugal in 200 – 500 m depth, differs from C. gracilis in having both early whorls and siphonal canal more stretched out; it was not found on GB.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

Fischer, 1868) (Fig. 24 H – K) Remarks There are two species of Colus Röding, 1798 to be found on GB (Fig. 24), and their correct identification is crucial since they are an important component of the benthic community and food chain. Both have extremely similar shells and their accurate identification relies essentially on the diagnostic character of the protoconch. Colus gracilis is found on the summit platform and the adult is somewhat larger and more solid, whereas C. jeffreysianus has a broad distribution on the deeper part of the slope. Colus aurariae Fraussen, Rosado, Afonso & Monteiro, 2009, described from off Portugal in 200 – 500 m depth, differs from C. gracilis in having both early whorls and siphonal canal more stretched out; it was not found on GB.

D63CF03CC340FFD48C23FB790D68F952.taxon	discussion	Remarks This recently described species is very different from any known eulimid in European waters. It is tentatively included in the genus Fusceulima Laseron, 1955, due to its small shell, with few, almost flat whorls, short aperture and curved outer lip (see diagnosis of Fusceulima in Bouchet & Warén 1986, Souza & Pimenta 2014 and Engl et al. 2021). It was described and illustrated for the first time as Balcis sp. by Rolán Mosquera (1983: 199), from the Galicia Bank.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

D63CF03CC34BFFDD8C60FB050DB0F9D5.taxon	description	Description Shell rather solid, creamy white, conical and elongated, up to 10.8 mm in height, 5.4 mm width. Protoconch paucispiral, globose, of 1 ½ whorl, 330 µm in nucleus diameter and about 650 µm in maximum diameter, smooth, with a clear thickened edge marking the transition to teleoconch. Teleoconch with up to 5 convex whorls, first whorl with 2 initially smooth and then slightly nodulose spiral cords, with third cord appearing at the end of this whorl. Spiral sculpture formed by 3 nodulose spiral cords on last 2 whorls, and 3 ‒ 4 more basal cords almost smooth on body whorl; uppermost basal cord meeting a level close to the suture at the posterior end of aperture. Axial sculpture formed by nodulose ribs, crossed by the three equally spaced upper spiral cords. Shell entirely marked by strong axial growth lines. Suture incised, with suprasutural furrow. Base conical, with 2 smooth spiral cords that emerge from the interior of the aperture. Aperture elliptical, outer lip thin, prosocline, smooth inside. Inner lip strongly reflected, with a thin and shiny vitreous callus on the parietal area. Columella somewhat inclined to right, with 2 strong folds, posterior larger, columellar end somewhat angled at its end and forming a weak siphonal canal when it meets the outer lip.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

D63CF03CC34BFFDD8C60FB050DB0F9D5.taxon	discussion	Remarks Specimens and shells of this species were only found in the deepest BANGAL samples (1631 ‒ 1720 m), together with shells of Brocchinia azorica (Bouchet & Warén, 1985) in samples V 2 and V 5. Brocchinia clenchi Petit, 1986 was originally described from the Josephine Bank at 610 ‒ 770 m depth (Petit 1986); the holotype being faintly sculptured and measuring 4.5 mm. The species was later found deeper (1350 ‒ 1360 m) in the same locality; shells and specimens were recorded from the Canary Islands (65 ‒ 1520 m), Selvagem Grande (830 m), Azores (15 ‒ 1250 m) and off Western Sahara (1000 ‒ 1100 m) (Verhecken 2002, 2007). Both extremes of the bathymetric range (15 ‒ 1520 m) are based on live collected specimens (Verhecken 2007). Verhecken (2007: fig. 29 c ‒ d) illustrated as B. clenchi two larger and more sculptured shells in a lot of six collected in PORCUPINE stn 28 (S of Sagres, 548 m, BMNH 1885.11.5.2607 – 12), which are closely similar to those from GB and were identified by Jeffreys (1885: 49) as ‘ Cancellaria mitraeformis, Brocchi’. Verhecken (2007) noted that shells of B. clenchi of similar size coming from shallow or deep waters of the Canary Islands may be faintly or strongly sculptured, whereas shells from deeper water were larger (up to 8.5 mm). He nevertheless preferred to consider one species awaiting for more material from different localities. In disagreement with this view, Rolán & Hernández (2009) described Brocchinia canariensis as different from B. clenchi. These authors also concluded that the paratype of B. clenchi (a shell of 6 mm, BMNH 1855.4.4.202, from the Canary Islands) illustrated by Petit (1986), as “ possibly the type of Cancellaria pusilla H. Adams, 1869 ” (a junior primary homonym of Cancellaria pusilla G. B. Sowerby I, 1832) was different from both B. clenchi and B. canariensis, therefore their choice to describe a new species from the Canaries rather than propose a replacement name for C. pusilla. Other N Atlantic species, as Brocchinia azorica (Bouchet & Warén, 1985) (see Fig. 25 F – I), B. pustulosa Verhecken, 1991, and B. nodosa (Verrill & S. Smith, 1885) have the inside of the outer lip smooth, but are larger and have a more solid and conical shell with stronger nodulose sculpture; B. azorica and B. nodosa also have multispiral protoconchs. The S Atlantic B. decapensis (Barnard, 1960) is the largest Atlantic species (up to 27.3 mm), and has also a more solid and conical shell. Finally, the NE Brazilian species Brocchinia verheckeni Barros & Lima, 2007 and B. harasewychi Barros & Lima, 2007, have a paucispiral protoconch, but they are smaller (up to 4.4 and 6.3 mm, respectively), less elongated than the species from GB, and have a stronger nodulose sculpture; B. verheckeni has lyrae inside the outer lip, whereas B. harasewychi lacks them (see Barros & Lima 2007). Superfamily Conoidea Fleming, 1822 This species-rich superfamily is represented on Galicia Bank by members of the families Cochlespiridae Powell, 1942 (Aforia Dall, 1889), Borsoniidae Bellardi, 1875 (Drilliola Locard, 1897, Retidrillia J. H. McLean, 2000), Mangeliidae P. Fischer, 1883 (Kurtziella Dall, 1918), and mostly Raphitomidae Bellardi, 1875 (Pleurotomella Verrill, 1872, Gymnobela Verrill, 1884, Austrobela Criscione, Hallan, Puillandre & Fedosov, 2020, Teretia Norman, 1888, Neopleurotomoides Shuto, 1971).

D63CF03CC337FFA38CE9FCB50AE3F9B8.taxon	discussion	Remarks The genus Tiberia is diagnosed by being umbilicate and having a straight columella with three folds, of which the two abapical ones are inconspicuous. The type species Pyramidella minuscula Monterosato, 1880 has a rather thick shell with brown spiral bands, one below the suture and another one above it, prolonged on the middle part of the last whorl. One specimen collected in 1720 m deep on GB (Fig. 28 D ‒ F) is definitely a Tiberia but differs from T. minuscula in being colourless, and in having a very thin shell with a markedly keeled last whorl. Pyramidella curtissima Locard, 1897, described from deep water (Travailleur 1881, stn 3, 3307 m; stn 30, 1203 m; Travailleur 1882, stn 13, 2030 m) off Portugal, is much stouter than the specimen illustrated here. The figured syntype could not be traced in the “ Travailleur ” and “ Talisman ” collection of MNHN, Paris; one shell with no indication of station number, labelled “ Portugal ” (Fig. 28 G) is in poor condition, and four other shells from “ Travailleur ” 1881 stn 31 (not mentioned in Locard 1897) are the rissoid Benthonella tenella. Without additional material at hand, the observed differences are not sufficient to demonstrate that our specimen is specifically distinct from T. minuscula and it is therefore reported as Tiberia sp.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

D63CF03CC333FFA78C5AFCA60C23F96F.taxon	discussion	Remarks Bouchet (1975) considered several deep-sea species of Ringicula as synonyms of R. nitida and, based on this, cited that species from several localities off the northwestern Iberian Peninsula, including GB. However, Mariottini et al. (2000) considered R. nitida as restricted to the Western Atlantic and referred the records by Bouchet (1975) to R. gianninii Nordsieck, 1974, which differs by having a higher spire, more convex whorls, and by forming a parietal tooth (“ columellar tooth ” in Mariottini et al. 2000) which R. nitida does not have. However, the specimens collected on GB have a low spire with slightly convex whorls and lack a parietal tooth, therefore being so similar to the lectotype of the American species (Mariottini et al. 2000: fig. 7) that, except for the geographic distance, we see no reason for their specific separation with the material at hand. The only difference observed is the number of spiral striae, which are around 30 in GB shells, less conspicuous in the abapical part of the whorls, while they are about 14 in the lectotype of R. nitida. Bearing in mind that most of the other heterobranchs present in the area such as Acteon monterosatoi Dautzenberg, 1889, Crenilabium exile (Jeffreys, 1870), Pyrunculus ovatus (Jeffreys, 1871) and Scaphander punctostriatus (Mighels & C. B. Adams, 1842) are considered amphiatlantic, we find more prudent to assign these specimens, tentatively, to R. nitida rather than describe them as a new species.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

Protoconch of a little more than half a whorl, smooth, without microsculpture even at high magnification. Teleoconch formed by 2 ½ whorls, the first one almost smooth, the last with about 38 ‒ 40 well marked, irregularly spaced spiral grooves which, under high magnification, appear as continuous series of square pits, and also with very fine growth lines; in the holotype there is also a growth stage in the last half whorl. Aperture slightly more than ⅔ of the total height, with two very marked columellar folds, the abapical one slightly larger, and with a very blunt and thick tooth in the middle of the parietal edge. Outer lip only slightly thickened, with a rounded edge. Very short siphonal canal.

It differs from it, however, because of its smaller size and more globose shape and lower spire with almost one whorl less. The great development of the parietal tooth, absent even in adults of R. nitida, indicates that, despite the scarce thickening of the outer lip, these are adult shells.

The species was again found off the Azores by Dautzenberg & Fischer (1896) and confirmed as valid. It was later reported from off the NW Iberian Peninsula by Fechter (1979) and transferred to the genus Cylichnium Dall, 1908. The size given 0.32 inches (8.1 mm) and the depth of the type locality are in good agreement with our material. Bouchet (1975) reported Cylichnium africanum (Locard, 1897) from R / V “ Thalassa ” stn X 336 in southern Bay of Biscay (44 ° 11 ′ N, 05 ° 10 ′ W, 1850 ‒ 2050 m). He considered it distinct from Cylichnium oliviforme because, in his words, the latter is more distinctly flattened below the suture and has a finely reticulated sculpture in the upper part of the last whorl. Nevertheless, according to these characters we consider the shell figured by Bouchet (1975: pl. 4, c) as conspecific with our material. Conversely Locard (1897: pl. 2 figs 15 ‒ 19) illustrated, to represent his Aceras africana, a shell in which the last whorl almost completely covers the spire whereas both the type of C. oliviforme and our specimens have a descending last whorl.

D63CF03CC33EFFA88C35FB880C7FFDA3.taxon	description	Description Shell small (holotype height 2.4 mm, diameter 1.2 mm), opaque white, cylindrical with a protruding spire. Protoconch of about 1.5 rounded whorls, with a diameter of ca 300 μm, sinistral with a very low spire, its coiling axis forming an angle of ca 100 ° with coiling axis of teleoconch, markedly protruding and distinctly demarcated from the teleoconch. The holotype has 2.5 teleoconch whorls, slightly convex, only ornamented with faint growth lines; last whorl being about 80 % of total height in apertural view, and covering most of the previous teleoconch whorl, adapically with a sharp keel situated at a short distance from the suture and delimiting a flat subsutural shoulder. Aperture occupying two thirds of the total height, broadly rounded abapically and gradually narrowing adapically. Columella curved, continuous with the parietal wall, delimited by a very narrow callus. There is no umbilicus. External lip thin and cutting, straight in its median part, markedly curved at both ends.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

D63CF03CC33EFFA88C35FB880C7FFDA3.taxon	discussion	Remarks This species is so distinctive that we describe it despite the very scanty material. Acteocina knockeri (E. A. Smith, 1872), described from shallow water of Benin, West Africa, is twice as large, with a proportionally tiny hyperstrophic protoconch, and the adapical part of the whorls has two keels and bears axial folds which project, crown-like, on the subsutural flat. Acteocina protracta (Dautzenberg, 1889), described from deep water off the Azores, also has a much smaller protoconch and the last whorl accounts for 90 % of total height in apertural view.

D63CF03CC33DFFAF8FC8FA720B4BFD98.taxon	discussion	Remarks There is a complicated nomenclatural and taxonomic history for the small Yoldiella species originally described by Jeffreys (1876) as Leda lata, from abyssal depths of the North Atlantic. The name is a secondary homonym of Nucula lata Hinds, 1843, for which reason it was renamed Leda jeffreysi Hidalgo, 1877. Allen et al. (1995) considered that Jeffreys’ type material comprised two different species; they used the preoccupied name Yoldiella lata for one of them and the replacement name Yoldiella jeffreysi for the other one, disregarding the nomenclatural rule (ICZN Art. 72.7) which makes them objective synonyms. The nomenclatural flaw was fixed by Killeen & Turner (2009), who endorsed the specific distinction, based Yoldiella jeffreysi on the lectotype of Y. lata (USNM 199696, from “ Valorous ” stn 16, west of Rockall Plateau, 1785 fms [3265 m]) designated by Allen & Hannah (1989) for their concept of Yoldiella jeffreysi, and named Yoldiella valorousae the second species (treated as “ Yoldiella lata ” in Allen & Hannah 1989), based on a shell (USNM 199695) from “ Valorous ” stn 9, off S Greenland, 1750 fms [3200 m]. Allen & Hannah (1989) and Killeen & Turner (2009) reported both species as widespread in the North Atlantic.

D63CF03CC33BFFB78C64F8AB0CF1FDCA.taxon	discussion	Remarks Most of the specimens collected during BANGAL 0711 were assigned to Policordia gemma as represented on Fig. 39 E ‒ F. Nevertheless, a second species, represented by only three specimens and one shell, was present in sample V 10 (1720 m) together with P. gemma and was tentatively identified in the preliminary INDEMARES BANGAL 0711 report (Gofas et al. 2014 b) and in Gofas et al. (2017) as Policordia atlantica Allen & J. F. Turner, 1974.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

D63CF03CC320FFB48C1CFD740B15FB0B.taxon	discussion	Remarks A specimen of this species from GB was figured by Rolán et al. (1990) as Cuspidaria capensis (E. A. Smith, 1885). Specimens from GB have a posterior rostrum shorter than usually seen in Cuspidaria rostrata, and are smaller, resembling in those features Cuspidaria meteoris Krylova, 2006, described from the mid-Atlantic seamount group. However, they do not show the sloping postero-ventral margin characteristic of the latter, and are therefore conservatively identified to the mainland species.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

D63CF03CC320FFB48C66FADC0AC9F83F.taxon	discussion	Remarks This species was mistaken in the preliminary INDEMARES BANGAL 0711 report (Gofas et al. 2014 b), for the similar M. angularis (Jeffreys, 1876) which has been reported from off Portugal (type locality) and off northwestern Morocco (Salas 1996: fig. 127) but not in Spain. The latter differs in having only one sharp keel delimiting the smooth posterior area and in having more numerous and finer commarginal ridges on the anterior and median part of the shell. Myonera acutecarinata (Dautzenberg & H. Fischer, 1906), described from off the Cape Verde Islands, is also very similar but more tapering posteriorly. Myonera bicarinata E. A. Smith, 1896 and Myonera dispar (Dall, Bartsch & Rehder, 1938) have been synonymized by Allen & Morgan (1981) but cautiously retained as separate species by Huber (2010), taking into account their type localities in the Indian Ocean and off Hawaii, respectively.

D63CF03CC32BFFBC8C37FE400B7DFA4A.taxon	discussion	Remarks This species was misidentified as Protocuspidaria colpodes (Dautzenberg & H. Fischer, 1897) in Salas (1996), in the preliminary INDEMARES BANGAL report (Gofas et al. 2014 b) and in Gofas et al. (2017), on the grounds that could be an older name, but Krylova (1995) convincingly recognized these as separate species and the GB specimens would then go to P. verityi.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

D63CF03CC32BFFBC8C37FE400B7DFA4A.taxon	distribution	Bathymetric distribution of the species There is a clearcut separation between mollusc communities on the shallower summit platform of GB and the deeper samples collected below the Mediterranean outflow (i. e., below 1200 m). This is highly supported when involving the beam-trawl catches only (Fig. 45 B) by the Bray-Curtis similarity index and a R ANOSIM value of 0.7 (both on quantitative and on presence / absence data). The grouping of the deep samples is also retrieved when taking into account all samples (Fig. 45 A), even though the sampled surfaces and the meshed are unequal between dredge, beam trawl and otter trawl. Table 3 shows the contribution of the species to the similarity between samples, calculated on the quantitative data for beam trawls only.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).

D63CF03CC32BFFBC8C37FE400B7DFA4A.taxon	discussion	Trophic groups Filter feeders, mostly the bivalves, account for more than half of the individuals collected (Fig. 46). Among these, Limopsis Sasso, 1827 represent roughly half of the specimens of the “ filter feeders ” group (but different species on the plateau and in the deeper samples), while the presence of the many ectoparasitic species (mostly, in the family Eulimidae) is testimonial from a quantitative point of view.	en	Gofas, Serge, Luque, Ángel A., Oliver, Joan Daniel, Templado, José, Serrano, Alberto (2021): The Mollusca of Galicia Bank (NE Atlantic Ocean).
