Abranchiate Terebellida; expanded circular upper lip that may be folded into three lobes (= trilobed or trefoiled) carrying two or three types of tentacles; segment 2 distinctly narrower than adjacent segments; paired ventro-lateral pads (= shields) present.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FF9FFFD2FF66A6ABC56BA2B9.taxon	discussion	Remarks. The subfamily Polycirrinae was erected by Malmgren (1866) to include Polycirrus Grube, 1850 and four other genera described by him in the same paper: Amaea (now Amaeana), Ereutho, Leucariste, and Lysilla. Since then Hauchiella Levinsen, 1893, Enoplobranchus Webster, 1879, and Biremis Polloni et al., 1973 have been added to the subfamily (Webster 1879; Hessle 1917). Today, six of the eight genera are still recognised, with Ereutho and Leucariste having been relegated to synonymy with Polycirrus (Hessle 1917; Holthe 1986 b: 146). The subfamily was elevated to family level in the cladistic analysis of terebellomorphs by Nogueira et al. (2013). Polycirrinae was found to be monophyletic by Glasby et al. (2004), supported by four synapomorphies, viz. loss of branchiae; trilobed upper lip; secondary notochaetae pinnate (some taxa only); and anterior venter with prominent paired lateral pads. Garraffoni & Lana (2008) also found in favour of a monophyletic Polycirridae with two synapomorphies that were essentially the same as the earlier study (prostomium with lateral expansion and ventral pads lower than the lateral pad), and two new ones (shape of the adult uncini and tube absent). In the most recent cladistic analysis of the group, Nogueira et al. (2013) confirmed the family’s monophyly and the presence of paired ventral shields as an unequivocal synapomorphy. The only other unequivocal synapomorphy in their dataset was segment 2 being distinctly narrower than adjacent segments.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FF83FFCEFF66A7A2C20CA106.taxon	discussion	Comments. Polycirrus abrolhensis is similar to P. clavatus (Kinberg, 1867), which was described from the northeast coast of Brazil at 9 ° S in 33 m (18 fms). The two species appear to be differentiable based on the form of the ventro-lateral pads (discrete in P. abrolhensis; poorly defined in P. clavatus) and the distribution of nephridial papillae (on segment 4 only on P. abrolhensis; segments 3 and 4 on P. clavatus). Garraffoni & Costa (2003) did not compare their species with P. clavatus, which is only very briefly described by Kinberg (1867). The redescription of P. clavatus in this study clarifies the attributes of this poorly known species.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FF81FFCDFF66A3CAC46CA528.taxon	discussion	Comments. We have synonymised P. insignis Gravier, 1907 with P. antarcticus (Willey, 1902) after finding no significant differences between the holotypes of both species. In particular, there are no differences in the number of notochaetigerous segments (11 in both species) and minimal difference in the segment having the first neurochaetae (segment 16 in P. antarcticus, segment 14 in P. insignis), which is acceptable intraspecific variability for the genus (see Table 1). Interestingly, Hessle (1917), Benham (1921), and Holthe (1986 b) all considered that P. antarcticus might also be a synonym of E. kerguelensis McIntosh, 1885 (now Polycirrus kerguelensis). However we reject this synonymy since there are significant differences between the two taxa, including the first occurrence of neurochaetae (segment 16 in P. antarcticus, segment 6 in P. kerguelensis) and the form of the notochaetae which are smooth in P. antarcticus and hirsute in P. kerguelensis.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FF86FFC8FF66A148C336A167.taxon	discussion	Comments. Based on a comparison of the syntypes of both P. arcticus and P. albicans, both of which were examined, we confirm Holthe’s (1986 b) view that P. albicans is a junior synonym of P. arcticus. The only differences between the two species are that P. albicans has a slightly tessellated anterior dorsum (smooth in P. arcticus), the number of notochaetigerous segments is 17 or 18 in P. arcticus (18 in P. albicans), neurochaetae begin on segment 16 in P. arcticus (15 in P. albicans), the number of post-gular membrane nephridial papillae (14 in P. arcticus; 6 in P. albicans). The differences in the number of nephridial papillae may be related to the sexual maturity of the specimen. The chaetal differences are not considered sufficient to regard them as two distinct species (see Table 1 for typical intraspecific variability ranges in the number of notochaetigerous segments and start of neurochaetae). Holthe (1986 b) reports a range of 15 – 22 notochaetigerous segments for P. arcticus. Although Sars mentions 17 or 18 notochaetigerous segments in the type description, his illustration only shows 14. Because the syntype specimens of P. arcticus are all in poor condition we have not designated a lectotype. Instead we have designated a lectotype from among the syntype series of P. albicans, and described and illustrated this specimen. The type locality of P. albicans was given as ‘ Spetsbergia’, which is now known as Spitsbergen. It is in the Arctic Circle about 1000 km to the NW of Vadsø, northern Norway, the type locality of P. arcticus.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FF8DFFFFFF66A411C342A2DB.taxon	discussion	Comments. No material was examined, and attempts to find material from the type locality failed. This is not surprising as Claparède was not in the habit of designating types (K. Fauchald, pers. comm.). As no type material exists and the original description is very brief, we suggest that P. caliendrum is a species inquirenda. Claparède (1870) figured the animal in dorsal view and a neuropodium, showing uncini. In general, diagnostic characters are not described; however, the uncini illustrated are clearly of Type 1 sensu Glasby & Glasby (1986). This is the same type as P. aurantiacus Grube, and as both species are reported to exhibit bluish or violet phosphoresence (Saint Joseph 1894), it is quite possible the two names apply to the same species, especially considering the proximity of their type localities on either side of Italy, viz. Gulf of Naples (P. caliendrum) and Croatia (P. aurantiacus).	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FFB0FFF9FF66A5A3C37DA458.taxon	discussion	Comments. There is some confusion in the literature on the type locality of P. clavatus. Most authors simply refer it to Brazil, but Carrerette & Nogueira (2013) appear to have introduced the more specific locality of Rio de Janiero. However, the type description clearly states that it was found from latitude 9 ° S, which puts it in the present State of Alagoas in northeast Brazil. Polycirrus clavatus is very similar to two other species described from Brazil: P. abrolhensis Garraffoni & Costa, 2003 from the Abrolhos Archipelago (18 ° S) in 10 m of water (see Comments for this species), and P. habitats Carrerette & Nogueira, 2013, collected from off Rio de Janeiro in 720 m. The similarity with the latter species is in fact quite striking, and based on a comparison between the holotype of Cyaxares clavatus Kinberg, 1867 and the comprehensive description of Carrerette & Nogueira (2013) we suggest formal synonymy of the two species. According to Carrerette & Nogueira (2013) P. habitats differs from P. clavatus in having notopodia extending to segment 17 (i. e., 15 pairs) and neuropodia beginning on segment 9 (an additional difference mentioned in their key is the presence of both limbate and pinnate notochaetae in P. clavatus, but present observations indicate that P. clavatus only has pinnate notochaetae like P. habitats). As can be seen in Table 1 the mean variation within a Polycirrus species in terms of number of notopodia is about five segments and for the start of the neuropodia is about four segments, so that P. habitats falls in the range of variation expected for P. clavatus. As there appear to be no other differences between the two species, apart from the uncini (which are taken from different parts of the body and therefore would be expected to be different), we propose that P. habitats should be relegated to a junior synonymy. The holotype of P. clavatus consists of only 16 segments, so we were unable to observe the uncini of the posterior body. Those of the anterior body (Fig. 16 d, e) however are not typical of Type 2 as defined by Glasby & Glasby (2006), which has an elongate rostrum, long neck and arched (concave) base. Nevertheless, the results of their morphometric analysis utilising all components of shape variation placed these uncini in the Type 2 category. It is likely that the uncini of the posterior body have a more typical Type 2 shape. As noted in the section on morphological characters, at least three other species show the combination of Type 2 uncini and early start of uncini occurring on poorly developed neuropodia. In addition, analysis of co-varying notochaetal characters by these authors provided further support for the grouping of this species with other species bearing Type 2 uncini.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

We dissolved the mounting medium and carefully peeled off the fragments of the specimen; however, it is now unidentifiable to species, although it clearly belongs to the genus. Therefore unless additional material is collected from this site, this species is indeterminate. The original description lacks illustrations and provides limited details regarding the noto- and neurochaetae. Verrill indicates that the type represents a small slender species, swollen anteriorly, attenuated posteriorly and consists of about 45 segments, and is 10 mm long and 1 mm wide; further he suggests it may be immature.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FFB9FFF3FF66A50AC38BA7D5.taxon	discussion	Comments. Gravier (1905) described this species from specimens collected at several localities in the Gulf of Aden including the Golfe de Tadjourah, from reefs off Pingouin and Météore, Iles Musha, and intertidally at La Résidence à Djibouti. Although Gravier (1905, 1906) provides an extensive description of the species, some key character information is missing. For example, he does not mention the presence of smooth chaetae in addition to the pinnate types and the first segment bearing neurochaetae is not stated. We have recorded this information from the syntypes. Other points of difference between the present description and that of the type description is that Gravier reports 14 chaetigerous segments (compared to 13 observed here) and nephridial papillae extending to chaetiger 12 (segment 14), but they were observed to extend only to segment 10 on the specimen we examined. Hartman (1959) considered that P. decipiens Gravier, 1905 was a junior synonym of P. coccineus; however, this view is incorrect because the two species have different uncini: P. decipiens has Type 1 uncini with teeth arranged in a single vertical series, whereas P. coccineus has Type 2 uncini arranged in a double transverse series.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FFBFFFF1FF66A652C28AA10D.taxon	discussion	Comments. The above description is a composite based on the type description and a specimen identified on the label as the type of P. denticulatus (MNHN Type 1547) from Concarneau, Brittany, collected by M le Baron de St. Joseph. This specimen does not fit exactly the type description in that there are no neurochaetae on segments 9 – 10, which are stated to be present in the type description. Further, the type locality is reported by Saint-Joseph (1894) to be the coast of Dinard, Britanny, NW France (48 ˚ 37.36 ’ N 2 ˚ 03.06 ’ W), whereas the information on the label of the MNHN Type 1547 says Concarneau, Brittany. According to Solis Weiss et al (2004) the types of P. denticulatus are registered at the MNHN under POLY TYPE 970 – 973. These specimens were recorded as having been collected in 1894 from Dinard, Brittany, France, which corresponds to the locality given in the type description. However, according to the current polychaete collection manager at MNHN, Tarik Meziane, 970 – 973 are actually parts of Type 1547 mounted on slides. Therefore, Type 1547 is tentatively regarded as the holotype, but the matter warrants further investigation considering the conflicting information on specimen versus description and on the type locality. According to the type description there are 13 – 17 notochaetigerous segments and the notochaetae are finely hirsute on one side only (the flexed, convex side). This condition suggests that the hirsuteness is a result of wear of a normal winged-type chaeta, and does not represent a true hirsute chaeta, which has hairs on both sides. The following additional character data for the posterior body are taken from the type description: neurochaetae begin on segment 9 – 10 before last notochaetigerous segment; there are 25 – 40 uncini per row; uncini have a short neck and straight to convex base (Type 1); teeth above the main fang are arranged in a double transverse series, there is an enlarged median tooth present above the main fang and the subrostral process is absent.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FFA1FFEAFF66A5D0C228A6AE.taxon	discussion	Comments. McIntosh described P. elisabethae in 1915, although briefly with no illustrations. Subsequently (1922) he illustrated the chaetae and formally synonymised it with P. haematodes (Claparède, 1864), described from Port Vendres on the French Mediterranean coast. However, after re-examination of McIntosh’s material, we believe that his specimens represent a distinct species and therefore should be removed from synonymy. McIntosh did not provide a precise locality for P. elisabethae in the original description, although from the title of his paper it is likely to be in the region of St Andrews, Scotland. However, the original label indicates that the specimens were collected from the debris of fishing boats at St Andrews. We have therefore designated the best specimen as the lectotype, and St Andrews is fixed as the type locality. Hessle (1917), Hartman (1959), and Holthe (1986 a) considered P. elisabethae to be perhaps the same as P. norvegicus. Although the two species are both in the North Sea (although on opposite sides), we reject this synonymisation because of differences in the shape of the lower lip (longer than wide in P. norvegicus and wider than long in P. elisabethae) and the shape and dentition of the uncini (more prominent subrostral process and 11 – 15 minute teeth surmounting the MF in P. elisabethae compared to only 1 – 4 larger teeth in P. norvegicus). It seems unlikely that P. elisabethae is synonymous with P. haematodes given the distance between type localities, but as we have been unsuccessful in locating the type material of P. haematodes, which we currently regard as a species inquirenda, the necessary comparison of type specimens is presently not possible.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FFA5FFE9FF66A2D7C392A6A6.taxon	discussion	Comments. The above brief description is based on the type description; however, there are insufficient data to allow us to fully code and differentiate this species. The original description has three illustrations: a lateral view of an uncinus that is short-handled (Type 1) and two notochaetae that have winged tips. The illustrations are very diagrammatic and not sufficient to characterise the species, therefore we have not reproduced them here. Leidy (1855) does not give a precise location as to where this species was collected, but indicates that the fauna described in this paper were collected from Narragansett Bay, Rhode Island, and in the vicinity of Atlantic City and at the mouth of Great Egg Harbour, both in New Jersey, USA. Verrill (1873) described P. eximius as having 25 notochaetigerous segments and uncini from chaetiger 8, and this description was repeated by Miner (1950). Day (1973) suggested that P. eximius is a very variable species with 16 – 31 notochaetigerous segments, neurochaetae starting on chaetigers 7 – 9, and 3 – 6 pairs of nephridia. Day suggested that as such variation is greater than typically exhibited by species of Polycirrus, his specimen from North Carolina, USA, with 25 – 31 pairs of notochaetigers should be treated as a separate subspecies. We have elevated the subspecies to a full species (see P. dubia above). Day (1973) examined material from Vineyard Sound, Massachusetts, identified by Verrill in 1881 (USNM 8165) and some fresh material from off Beaufort in 5 – 80 m; he documented some variation in the number of pairs of notopodia and nephridial papillae present. It seems likely that Day was in fact examining more than one species. Day (1973) also states that the type of Torquea eximia Leidy is lost, the description is inadequate, and the original drawings are too small to show specific characters. We agree with Day (1973) and suggest that the species be treated as species inquirenda until additional material is available.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FFA5FFE8FF67A6ABC433A5CF.taxon	description	Description. Based on type description and figures. Type series consists of 29 specimens, up to 35 mm long for 65 chaetigers, body thicker than other members of the genus, wide, relatively short. Body colouration whitish when preserved. Venter anteriorly with mid-ventral groove and discrete ventro-lateral pads; pads more-or-less smooth, extending from segment 3 to 16 (at least). Mid-ventral groove from segment 2. Upper lip trefoiled, small wing-like lobes laterally (four folds are actually mentioned in type description; the extra fold is here interpreted as a convoluted medial lobe), margin of medial lobe convoluted. Outer lower lip subconical lobe protruding above venter (inferred from Fig. 27 a). Notochaetigerous segments 19 – 21, extending to segments 21 – 23 (range of notochaetigerous segments for all specimens 18 – 25). Notopodia papilliform (inferred from Fig. 27 a). Notochaetae within a chaetiger one type, gradually elongating from dorsal to ventral, smooth, narrowly winged (although wings not visible in fig. 2 of type description), uniformly tapered (Fig. 27 b), posteriorly same form as those anteriorly. Neurochaetae beginning on segment 13 – 15, 20 uncini per row (approximation based on fig. 1 of type description). Neuropodial tori ridge-like, differ along body: relatively long on anterior chaetigers, longest in mid-body, becoming short on posterior chaetigers. Uncini with short neck and straight to convex base (Type 1), teeth above main fang arranged in double transverse series, subrostral process tooth-like (Fig. 27 c).	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FFAAFFE6FF66A18AC7ADA615.taxon	discussion	Comments. No type material exists as Claparède was not in the habit of designating types, and as the original description is very brief, we suggest that this is a species inquirenda. Attempts to locate any material from the type locality were unsuccesful. McIntosh (1922) synonymised P. elisabethae with P. haematodes (Claparède, 1864); however, without type material of the latter we cannot assess that validity of this synonymy. Holthe (1986 b) provides a description of this species but it is unclear where his specimens were collected. He gives a very broad geographical distribution for this species, including the Mediterranean, the eastern North Atlantic to Madeira and the west coasts of Ireland and Scotland. We suggest that several species may have been confused under this name. Langerhans (1884) illustrates a Type 1 uncinus from a specimen from Madeira (see also Glasby & Glasby 2006).	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

The size and chaetiger numbers do not match. Further, Benham states in his original description that one of the specimens is a mature female, whereas (AM W 611) contains two mature males; however, in all other respects the material fits Benham's description and is accepted here as representing syntype material. It is likely that the syntypes were designated after Benham (1921) described the species P. hamiltoni.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FFAFFFE1FF66A457C55EA048.taxon	discussion	Comments. The dental formula for the thoracic neurochaetae provided by Londoño-Mesa & Carerra-Parra (2005) suggests three rows of teeth above the main fang, yet their figure (Fig. 31 e) shows only two rows, at least in the way that we interpet a row (successive curved lines of teeth). Therefore using our definition, the dental formula would be MF: 1: 8 – 10. Another discrepancy between the description and the figures is in regard to the position of the nephridial papillae. Londoño-Mesa & Carerra-Parra (2005) state that they are posterior to the notopodia, but figure 31 a, b clearly show them to be anterior to the notopodia.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FFD2FF9DFF66A7DCC71DA175.taxon	discussion	Comments. Although the material examined is not labelled as types, it matches well with the description by Verrill (1900) and is from the same locality, Bailey Bay, Bermuda. We agree with Londoňo-Mesa (2009) that they are probably the type specimens. The view that P. luminosus is a junior synonym of P. purpureus (type locality, Jamaica) held by Hartman (1959), Holthe (1986 a), and Londoño-Mesa (2009) is not accepted here as differences were noted in the types of both species including the form of the upper lip and shape of the uncini (see below for description of P. purpureus). Possibly the view is based on Augener’s (1925) opinion that the two species are synonymous, but Augener’s view was based on an examination of the types of only one of these species (P. purpureus).	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FFD0FF9BFF66A58EC31BA61E.taxon	discussion	Comments. McIntosh (1885) described two different species named kergulensis in two different genera (Polycirrus and Ereutho). As the two names are now considered to represent the same genus, Ereutho kerguelensis becomes a member of Polycirrus. Unfortunately this renders P. kerguelensis McIntosh, 1885 as a junior homonym on the basis of page priority. We therefore propose a new name, Polycirrus macintoshi n. nom., for P. kerguelensis. Earlier, Hartman (1966) synonymised E. kerguelensis with P. kerguelensis with no comment. She also gave a composite description of a species with 11 – 15 pairs of notopodia and neurochaetae from the first to the third last notopodium, which is an unusual configuration. We suggest that at least two species have been confused and all references listed by her on page 106 require a re-examination of material. However, we can confirm that material identified by Gravier (1911) as P. kerguelensis, as listed in the synonymy of Hartman (1966), is correct.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FFD5FF99FF66A167C54CA4F8.taxon	discussion	Comments. Grube’s (1850) description of the species is very brief (two lines); in a later paper (Grube, 1855) he gives a more comprehensive (for the time) account of the species, but it is inadequate by today’s standards to differentiate the species from several other Polycirrus species. In this latter paper he also refers to the type locality as Villa Franca (near Nice, France). Further, a possible holotype was in the collection of the Museum für Naturkunde der Humboldt-Universitat, Belin, but has been lost (Holthe, 1986 b). Thus, designation of a neotype was deemed necessary. We have designated a neotype of P. medusa as the type of Polycirrus by monotypy from Anse du Rouet, just west of Marseille collected from a similar habitat. The neotype shows some resemblance to the description of material from the North Sea identified as P. medusa by Holthe (1986 b), but it is not conspecific as he refers only to plumose (= pinnate) notochaetae unlike the neotype which has both smooth and pinnate types in the same notopodium. The identity of Holthe’s material is uncertain given that he does not specify material examined and that several similar Polycirrus species exist in the region.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FFDBFF96FF66A63FC474A4CE.taxon	discussion	Comments. While the original description states that the type is held in the collections of the Institute of Biology, attempts to locate it have been unsuccesful. We believe that these collections were transferred at some point to the National Museum in Mexico City, which was damaged during an earthquake. Rioja does not state in the original description where the neuropodia start in relation to the notopodia. Almost certainly they begin after the last notochaetigerous segment as this would account for Rioja’s placement in the genus Anisocirrus, which is defined by its lack of neurochaetae on the ‘ thorax’. However, whether they begin one or two segments after the last notochaetigerous segment or well after this (couplet 1, key) is unknown. Therefore, this species was included twice in the key.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

However, Fig. 41 c shows only one row of teeth above the main fang. Therefore, using the present dental formula concept (i. e., counting teeth as a series in curved rows; see Table 2) the formula should be MF: 8 – ∞, that is, eight to many teeth arranged in a single curved row above the main fang.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FFC6FF8AFF66A2AFC4CEA707.taxon	discussion	Comments. The species has been thoroughly described by Carrerette & Nogueira (2013) and the description is not repeated here. We have included it in the key to facilitate identification and comparison with other species. Carrerette & Nogueira (2013) note the alliance of this species with other Group 1 A taxa identified by Glasby and Glasby (2006), i. e., having Type 1 uncini and notopodia terminating before segment 20, and they make a number of comparisons with other Group 1 A species. However, they do not compare their species with P. medusa, which we find to be most similar based on characters used in the key. Polycirrus papillosus may be easily distinguished from P. medusa by the form of the ventral pads (papillose in former, smooth in the latter) and the more elongate base of the uncini in P. papillosus compared to P. medusa.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

No material of this species can be located in the Museum d’Histoire Naturelle in Paris, where one would expect Quatrefages’s material to be lodged. The original description is too brief to allow it to be coded. Attempts to recollect material from the type locality or find additional material collected from there were unsuccesful. We therefore agree that P. pellucida is a species inquirenda as previously suggested by Hartman (1959).	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FFCFFF82FF66A799C6D2A24B.taxon	discussion	Comments. The above description is scored primarily from Holthe (1986 b), which appears to be based on material collected in the Faroes, the eastern North Sea, the west coast of Sweden, and western Norway near the type locality. The one exception is that the ventrolateral pads are illustrated by Wollebaek (1912) as being slightly papillose (Fig. 48 a), whereas this detail is missing in Holthe’s illustration. According to Holthe (1986 b) the type should be in the Zoological Museum, Oslo; however, our correspondance with this institution indicates that they have failed to locate the types. Wollebaek provides sufficient character information for the species to be accepted as valid.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

Inner lower lip oblong, narrow, smooth; outer region flat, shield-like, oblong, wider than long, smooth, extending posteriorly to segment 3. Achaetous segments visible dorsally but obscured by expanded outer lower lip ventrally (Fig. 53 a, b). Notochaetigerous segments 10 – 11, extending to segments 12 – 13. Notopodia digitiform, short, lobes similar, low and rounded.

03CD87A2FFCEFFBFFF66A51AC6BEA1D8.taxon	discussion	Comments. According to Hartmann-Schröder (1990), nephridial papillae are present on chaetigers 1 – 3 of the holotype, that is, segments 3 – 5. Those on segments 3 and 4 would represent pre-gular membrane nephridial papillae as defined here. The ones on segment 5 would be post-gular membrane nephridial papillae. The shape of the anteriormost uncini in P. pumilis is not typical of Type 2 as defined by Glasby & Glasby (2006), which has an elongate rostrum, long neck and arched concave base; however, the results of their morphometric analysis utilising all components of shape variation placed these uncini in the Type 2 category. In addition, analysis of co-varying notochaetal characters by these authors provided further support for the grouping of this species with other species bearing Type 2 uncini. Polycirrus pumilis probably belongs to a group of Type 2 species having dimorphic uncini; these species also have early commencement of neuropodia, i. e., prior to segment 10.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

03CD87A2FFF6FFB8FF66A64CC411A705.taxon	discussion	Comments. The above description is coded from the type descrition. Hartmann-Schröder (1960) interpreted the tentacles on the lateral part of the upper lip as possible branchiae; also she thought that an enlarged tentacle represented a palp — hence the view that the animal belonged to Ampharetidae; she corrected herself in a later publication (Hartmann-Schröder, 1962) transferring the genus to Polycirrinae. We have compared the type material of P. multisetigerous (from Chile) with the type description of Pseudoampharete tentaculatus (from northern Peru) and found the two species to be very similar, differing only in the following features: anterior dorsum is tessellated in P. multisetigerous and smooth in P. tentaculatus, the mid-ventral groove begins from segment 2 in P. multisetigerous (segment 1 in P. tentaculatus), the upper lip is trefoil shaped in both species, but with small lateral wing-like lobes in P. multisetigerous and lateral blindly ending closed diverticulae in P. tentaculatus, the oral surface of the upper lip lacks grooves leading to the mouth in P. multisetigerous but the grooves are present in P. tentaculatus, the outer lower lip is subtriangular and elevated in P. multisetigerous but oblong and longitudinally grooved in P. tentaculatus. There are no significant differences in the more reliable characters, viz. number of notochaetigerous segments, notochaetae and the segment on which the uncini start. However, we propose maintaining the two species as separate entities, but the hypothesis that they are conspecific should be tested when more material becomes available of each species, including mature specimens to allow comparison of the form and arrangment of nephridial papillae.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).

Holotype poorly preserved with body wall damaged, chaetae present mainly intact, yellowish brown in colour, consists of fragments of probably two individuals. First individual anterior fragment 4.0 mm long, 1.0 mm wide excluding buccal tentacles, with eight segments. Second individual with anterior fragment 12 mm long, 1.2 mm wide for about 21 segments but posterior portion damaged and poorly preserved. Median fragment 30 mm long, 1.2 mm wide. Two posterior fragments with following dimensions: 12 mm long, 1.2 mm wide, and 20 mm long, 1.2 mm wide, only anterior 5 mm well preserved. Sex unknown. Dorsum anteriorly tessellated. Venter anteriorly with mid-ventral groove and discrete ventro-lateral pads; pads incised and tessellated. Buccal tentacles numerous, of two types: (1) cylindrical, thickened distally and distinctly grooved and (2) cylindrical, uniformly thin and weakly grooved, both arising dorsally on prostomial ridge. Prostomial ridge distinctly curved, extending laterally along anterodorsal base of upper lip. Upper lip trefoiled with lateral, blindly ending, enclosed diverticulae, margin of medial lobe convoluted, glandular; oral surface glandular, ciliated, with grooves leading to mouth. Inner lower lip oblong hidden by upper lip, ridged; outer region flat, shield-like, subtriangular and pointing toward mouth, inflated, ridged and grooved, extending posteriorly to segment 3.

The University Museum of Zoology, Cambridge, has a policy of not sending material in the mail and thus the types had to be examined in the Natural History Museum, London. Facilities for drawing the anterior end were not available; thus, the anterior end of the species unfortunately remains unfigured.

03CD87A2FFF8FFB2FF66A03AC5F1A128.taxon	discussion	Comments. Hutchings & Glasby (1986) report the following variation in the paratypes: 10 – 17 notochaetigerous segments, neurochaetae from segment 15 – 19 (Table 1). Summary In this paper we have revised the genus Polycirrus based on a morphological study of the type material of most of the approximately 74 nominal species; 59 species, including a new species from the Pacific coast of Panama, are accepted as valid. We have provided a standardised illustrated description of most of these valid species. A small minority of nominal species could not be described because the original description is poor and no type material could be found; these 10 species have been designated as species inquirenda (Appendix). Nominal species lacking type material but having a sufficiently detailed original description that could be standardised using the present character set were accepted as valid provided they could be clearly differentiated from other species in the genus. Standardisation will facilitate future descriptions of species of Polycirrus as we are aware that many more remain to be described, including some in Australia and in New Zealand (four new species). However, well-preserved, intact specimens are needed and often they are damaged during collection. This study was based mainly on an examination of type specimens in order to clarify the validity of existing species; we have been unable to fully characterise the morphological limits of each species, apart from synthesing available data on intraspecific variability in the number of notochaetigerous segments and the first appearance of neuropodia. Future taxonomic studies of Polycirrus would be rewarded by a more thorough consideration of morphological variability, as currently we do not have a good understanding of the range of variability that can be accepted for each species. This applies in particular to intraspecific variation of uncini shape within each species and a better understanding of the form and distribution of nephridial papillae in relation to sexual maturity.	en	Glasby, Christopher J., Hutchings, Pat (2014): Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae).
