Self-overgrowth not usual, but possible from loci of damaged zooids through reparative budding, or on small pebbles where lateral expansion is restricted. Colony pink in newly forming zooids to red in fully formed and ephebic zooids, the pigment residing in epithelial tissues in foramina, under the operculum, and in the cells of the pharynx and oesophagus, thus imparting colour to the introvert, whereas the tentacles are colourless. Polypide with 14–17 tentacles. Autozooids contiguous, quincuncially arranged, 0.39–0.68 mm long (0.51 ± 0.08 mm), 0.22–0.47 mm wide (0.37 ± 0.07 mm). Gymnocystal frontal shield scarcely elevated, perforated by 3–7, rarely only 2, large oval to circular foramina; these with inwardly sloping sides, inner diameters of each foramen smaller than outer diameters; foramina covered in life with an epitheca. Orifice having a somewhat hatshaped outline, the anter high-arched and rounded with the proximal corners somewhat condyle-like; poster wider than anter, the proximal rim nearly straight though tending to sinuous, extended at the corners where there are lateral indentations. No peristome, umbones, spines, or avicularia. Maternal zooids with internal brooding of embryos, the distal zooidal wall strongly convex, overarched by a distal kenozooidal chamber whose extensive frontal wall resembles an ovicell; this perforated by a relatively large circular foramen with inwardly sloping walls, the foramen covered in life with an epitheca. Maternal orifice slightly broader (0.24–0.26 mm wide at the proximal margin) than that of autozooids (0.15–0.22 mm). Zooids communicating by 1–2 distal and 2–3 basolateral pore-chambers. Ancestrula subcircular with entire frontal area membranous, 0.40–0.42 ¥ 0.32–0.38 mm, larger than immediate daughter zooids; no spines; operculum with narrow subperipheral sclerite; ancestrular polypide with 13–15 tentacles. First daughter zooid budded mid-distally.</p> <p>Remarks</p> <p>As originally described, autozooids of E. foraminigera sensu stricto have several frontal foramina — Hincks (1883) illustrated 3–5. Very rarely, zooids may have only two, especially if they are constrained in their growth. At least one other New Zealand species (E. biperforata sp.nov.) has been consistently confused with E. foraminigera. Its zooids have only a pair of oval to circular foramina (rarely one) (see Brown, 1952; Powell, 1967; Gordon, 1984, 1989). A rarer, second new biperforate species (E. aupouria sp. nov.) has narrowly crescentic foramina. These three species also share a feature first noted, and illustrated, by Brown (1952), namely a median triradiate suture in the proximal rim of the orifice. His observations are germane to the phylogenetic relationships of eurystomellids: “the proximal lip of the orifice closely resembles the ‘apertural bar’ of Figularia... for it appears to be formed by the coalescence of a pair of lateral, spiny processes, and, as in that genus, often shows a tiny median notch where the primitive spines have joined”. Scanning electron microscopy has allowed close examination of this feature, lending strong support for Brown’s interpretation. Gordon (1989), for example, interpreted the triradiate suture as indicating the boundaries between contiguous vestigial costae, noting similar features in the orificial rims of some catenicellids.</p> <p>Ryland (1975) gave parameters of the lophophore in E. foraminigera from Goat Island Bay, Leigh, on the north-east coast of North Island (36°16¢S, specimens collected November 1971). The number of tentacles varied from 14 to 16 (mean 15.17). Mean tentacle length was 0.504 mm (SD 0.053 mm) and mean funnel diameter 0.530 mm (SD 0.028 mm). These figures accord with specimens freshly collected (February 2001) from Greta Point, Wellington (41°18¢S) which have the same range in tentacle number. Tentacle length and lophophore diameter can attain 0.566 mm and introvert length (measured from the plane of the orifice to the base of the lophophore) 0.415 mm. Faecal pellets measure 0.134 ¥ 0.068 mm, are circular in cross section, and rounded at each end.</p> <p>Distribution</p> <p>Eurystomella foraminigera is endemic to New Zealand. Its exact geographical and depth distributions are uncertain owing to previous confusion of this species with E. biperforata. It certainly occurs from Spirits Bay at the far north of North Island, along the north-east coast of Northland, and from Wellington Harbour, at depths of 0– 76 m. Whitten (1979) reported living colonies from the intertidal to 21 m depth, and transported colonies to 82 m depth in the vicinity of the outer Hauraki Gulf. Eurystomella foraminigera is among the more commonly encountered bryozoans of the middle to lower shore around New Zealand, encrusting shells, plastic, broken glass, brown algal holdfasts (Carpophyllum maschalocarpum (Turner) Grev., Ecklonia radiata (C.Agardh) J.Agardh, and the undersides of boulders (Gordon, 1967; Stevens et al., 1996). The reddish coloration of the colonies makes them conspicuous.</p> </div>	http://treatment.plazi.org/id/039B3920286D774BFF36FF59FEE7D420	Public Domain	No known copyright restrictions apply.

Whereas the interior of the frontal shield in E. foraminigera is uniformly smooth and featureless (apart from the foramina), that of E. biperforata has an abrupt demarcation in its angle of slope, creating a line that curves around the proximal margins of the foramina.

According to Soule et al. (1995), autozooids of I. bilabiata are 0.60–0.65 mm long and 0.50–0.55 mm wide with an orifice width of 0.30–0.32 mm (hence the widths of zooids and orifices do not even overlap in the two species). Additionally, the shallow gymnocystal excavations in I. novella are proportionately very much longer whereas the kenozooidal foramen is tiny and surrounded by a broader area of interior wall.</p> <p>Apart from those sources already mentioned, Integripelta bilabiata has been recorded or described by Hincks (1882, 1884), Robertson (1908), O’Donoghue &amp; O’Donoghue (1925, 1926), Osburn (1952), and Banta (1973). Soule et al. (1995) gave its range as Nootka Island, Alaska, through British Columbia to southern California and to Navidad Head, Mexico, at depths of 168–237 m, but it has also been recorded intertidally (McBeth, 1971). It is also known from the Pleistocene of southern California (Soule &amp; Duff, 1957). Robertson (1908) described the operculum of I. bilabiata in some detail — it appeared to be two-layered and, together with the distal rim of the orifice, the whole structure appeared to be superficially bilabiate. Judging from observations on I. sextaria (below) the ‘bilabiate’ appearance obtains in dried material, in which the distal vestibular wall may be accentuated if slightly protruding. While the operculum proper may be thin, a descending cuticular rim around its periphery can give the appearance of thickness. The orificial structure of I. japonica (below) is not known.</p> <p>Distribution</p> <p>Known with certainty only from the intertidal zone at the type locality in Hokkaido.</p></div> 	http://treatment.plazi.org/id/039B392028697749FE82FED6FB03D4B6	Public Domain	No known copyright restrictions apply.

The two species appear similar, but published SEM micrographs (Cook &amp; Chimonides, 1981) allow comparison of the key taxonomic features, permitting ready discrimination of the two species. In I. bilabiata the autozooidal orifice is proportionately larger than in I. japonica (almost half the size of the zooid) with larger proximolateral excavations on the edge of the gymnocyst (see Cook &amp; Chimonides, 1981; fig. 5D, arrows), the maternal orifice is dimorphic, a low umbo and/or carina is often present, and the ‘ooecial kenozooid’ is larger with a larger foramen. In his original description, Hincks (1882) noted that the zooids in I. bilabiata were ‘short’ and that the ‘ooecium’ had a ‘large foramen’ (see also Hincks, 1884). The above synonymy is suggested by the published illustrations of specimens described by Kataoka (1960) and Hayami (1970, 1974). We have not examined these specimens, but the relative proportions of the orifice in relation to the entire zooid strongly indicate that they were I. japonica, not I. novella, which is somewhat intermediate between I. bilabiata and I. japonica in the zooid length:orifice length ratio.</p> <p>Distribution</p> <p>Southern Japan Sea off south-western Honshu, 89–94 m (Seto Marine Biological Laboratory Collection).?Also Japan Sea, western Honshu, 151 m (Kataoka, 1960), and Early Miocene of south-west Hokkaido and central Honshu (Hayami, 1970, 1974).</p></div> 	http://treatment.plazi.org/id/039B392028697747FC16FC53FD70D12D	Public Domain	No known copyright restrictions apply.

Traces of these slits, paired or distally continuous, occur in incompletely formed autozooids, i.e. kenozooids. No peristome, umbones, spines, or avicularia. Orifice of maternal zooids larger overall than in autozooids, the distal kenozooid with a large, transversely elongate foramen sloping distad.

Ancestrula not known.</p> <p>Etymology</p> <p>After Professor Yoshihisa Shirayama, director of the Seto Marine Laboratory, Shirahama, Kii Peninsula, in recognition of his contributions to biodiversity appreciation in Japan.</p> <p>Remarks</p> <p>This is a very striking species, easily recognizable by the crescentic lateral slits, which are very conspicuous in dead zooids. Okada (1929) attributed specimens in his collection from Mutsu Bay to Eurystomella bilabiata but illustrated the slits and, in one zooid, a spine-like umbo, described in the text as keel-like or carinate and restricted to older zooids. None of the specimens we have examined show this latter feature. Eurystomella shirayamai is also distinguished on the basis of the ‘ooecial kenozooid’, the foramen of which is larger and more bean-shaped than in E. bilabiata.</p> <p>Cook &amp; Chimonides (1981) noted the crescentic lateral slits illustrated by Okada (1929) and Sakakura (1935) and also discovered them in a specimen in The Natural History Museum, London (BMNH 1885.8.29.1) from “Sio-u-whu Bay”. [This name, not found in modern atlases, refers to a locality south of Vladivostok, Russia, in the Japan Sea. The coordinates on the label give the following data: “Sio-u-whn(u) Bay, Gulf of Tartary, 42°N, 133°S ”.] Cook &amp; Chimonides (1981) wrote: “Some of the Japanese populations have been reported to show characters [sic] states which vary somewhat from those of the eastern Pacific specimens. [The slits] are covered by brown cuticle which appears to be continuous distally with that of the operculum”. This observation accords with our interpretation that the slits are lateral extensions of the indentations seen at the proximolateral corners of most eurystomellids (see Cook &amp; Chimonides, 1981). Unfortunately, the specimens available to us were all dead and lacked opercula and membranes. The narrow shelf below the outer edge of each slit is clearly homologous with the excavations that occur in the gymnocysts of species like I. novella sp. nov. and I. sextaria sp. nov. (cf. Figs 2A, B, F and 3C). One other possibility is that the slits represent frontal foramina that have migrated laterally; this is suggested by their presence in kenozooids lacking orifices, but, in one instance, the kenozooidal slits are distally continuous and the distal part of the inverse U-shaped slit is suggestive of aborted orificial development. Further, the distalmost parts of the frontal gymnocyst merely abut, and do not fuse, with the proximal corners of the ‘ooecial kenozooid’, such that organic continuity between the operculum and the slits is possible just at or under the loci of abutment.</p> <p>Distribution</p> <p>Integripelta shirayamai is endemic to east Asian waters. It has been reported (as Eurystomella bilabiata) from numerous localities in Mutsu Bay, northern Honshu (Okada, 1929), from south-eastern Honshu (Mawatari, 1952), and south of Vladivostok in the Japan Sea. Pleistocene material was illustrated by Sakakura (1935), who found specimens to be very rare to common in the Dizôdô beds of the Bôsô Peninsula, eastern Honshu. Specimens examined for this paper were collected off Saiki-wan, eastern Kyushu (courtesy of the Seto Marine Laboratory).</p> </div>	http://treatment.plazi.org/id/039B392028677745FF73F9D8FE7CD2BC	Public Domain	No known copyright restrictions apply.
