BOUCHET & A. WAREN ABSTRACT A revision of the deep sea neogastropods (excluding Turridae) is presented. The area surveyed covers the Atlantic N of 33° N, E of the Mid Atlantic Ridge, including the Mediterranean and the Norwegian Sea. Only species normally occurring below 300 m are included. All previously published material and unpublished material from the French, British and German deep sea programmes is included. The revision includes species of Muricidae, Coralliophilidae, Nassariidae, Fasciolaridae, Co- lumbellidae, Bucciniaae, Olividae, Volutomitridae, Turbinellidae, Cancellariidae and Marginellidae. About 385 names of the species category are discussed and reduced to 80 species. The new species Pterynotus atlantideus, Microvoluta superstes, Metzgeria gagei, Iphinopsis alba, I. fuscoapicata, Admete azorica, Volvarina ingolfi and Marginella aronnax are described. Buccinum sulca¬ tum Friele is renamed B. kjennerudae, Turrisipho lachesis var. bicarinata (Friele) is renamed T. voerin- gi and Colus ventricosus (Gray) is renamed C. terraenovae because of homonymy. RIASSUNTO La presente revisione dei Neogastropodi di grande profondita segue la revisione dei Turridae ba- tiali e abissali dell'Atlantico nord-orientale, pubblicata dagli stessi autori (1980). La regione esamina- ta comprende 1’Atlantico settentrionale a nord del 33° parallelo e a est della dorsale medio-oceanica, ivi compresi il Mediterraneo e il mare di Norvegia. Sono prese in considerazione solo le specie che vivono normalmente sotto i 300 m di profondita. La revisione si basa su tutto il materiale storico e sul materiale proveniente dai programmi di studio del benthos profondo francesi, britannici e tedeschi. In questo volume sono trattate le seguenti famiglie: Muricidae, Coralliophilidae, Nassariidae, Fasciolariidae, Columbellidae, Buccinidae, Olivi¬ dae, Volutomitridae, Turbinellidae, Cancellariidae e Marginellidae. Sono state discusse 385 denomi- nazioni di gruppo-specie con conseguente riduzione a 80 specie valide. Infine sono state istituite otto specie nuove e sono state proposte tre nuove denominazioni. Per quanto concerne la nomenclatura e la sistematica delle specie mediterranee si perviene alle seguenti conclusioni: 1. Trophon echinatus (Kiener, 1840) e il nome valido per la specie nota generalmente come Pago- dula vaginata e P. multilamellosa. Questa specie presenta un cline batimetrico: le popolazioni batiali atlantiche e mediterranee (-250 / -600 m) appartengoono alia forma grimaldii Dautzenberg & Fischer, caratterizzata da un maggior numero di lamelle assiali rispetto a quelle della piattaforma continen- tale. 2. Coralliophila squamosa (Bivona, 1838) e il nome valido per la specie nota come C. alucoides e C. squamulosa, entrambe pre-occupate. 3. Coralliophila lactuca Dali, 1889 e sinonimo di C. richardi (P. Fischer, 1882) che ha quindi prio¬ ri ta. 4. Nassarius frigens (v. Martens) ha distribuzione limitata all’Atlantico dell 'Africa tropicale e sub- tropicale. La presenza di Nassarius wolffi (Knudsen, 1956) in Mediterraneo resta da confermare. 5. Fusinus gigliolii (Monterosato, 1890) e da considerarsi come una forma di profondita, priva di valore tassonomico, di F. rostratus (Olivi, 1792). 6. Amphissa acutecostata (Philippi, 1844) e il nome valido della specie nota sotto il nome, pre- occupato, Amphissa costulata. 7. Il genere Colus e rappresentato in Mediterraneo solamente da C. jeffreysianus (Fischer, 1868). 8. Granulina Jousseaume, 1888 e il nome del genere valido per le piccole Marginellidae general¬ mente note sotto il nome Gibberulina e Cypraeolina. NORTH-EAST ATLANTIC NEOGASTROPODA 125 INTRODUCTION This revision forms part 2 in a series treating the NE Atlantic deep sea gastropod fauna. For the first part, see Bouchet & Waren (1980). The revision is based on all material we have been able to examine, from numerous sources, which are listed in part 1. For part 2 we have to a higher degree been able to base our work on material in Scandinavian museums, because much of the revision involves northern members of the family Buccinidae. Detailed information about this material can be found in Thorson (1941, 1944, 1951) and Friele & Grieg (1901). We have also been able to use a large supply of material from the Rockall Trough, collected by Dr John Gage from R.V. Challenger II. This material is now in the Royal Scottish Museum, Edinburgh. A rich supply of NW Atlantic buccinids was collected by Dr J.C. Mahe, Institut Scientifique et Technique des Peches Maritimes, St Pierre & Miquelon, and put at our disposal. The material is now in MNHN. Several members of the Bologna group of the Unione Malacologica Italiana have contributed material of rare Mediterranean shelf species and fossil material from their private collections. Material from the French Seabed and Walvis expeditions has also been used. The area investigated by these expeditions is to the south of the area we have covered, but the material was useful for comparisons. It is now in MNHN. Abbreviations are listed in part 1 . SPECIES REFERRED TO TAX A NOT TREATED IN THIS PART Sipho leptaleus Verrill, 1884:175, pi. 31, fig. 14. We have examined the holotype (USNM 202879), from off Martha’s Vineyard, 810 m (off the NE US), and it proved to be a turrid, probably a species of Ta ranis. Nassa nigrolabra Verrill, 1880:371, from off Martha’s Vineyard, 280 m. We have examined the holotype and it is a larval shell, probably of a cymatiid. Trophon maclaini (Dali, 1902), described from off Greenland, does not belong to Trophon, but was based on a species of Oenopota (Turridae). We have examined the holotype, USNM 126 194, and it must have been a slip of the pen when Dali placed it in Boreotrophon. 126 P. BOUCHET & A. WAREN Family MURICIDAE Among the muricids, it is the genus Trophon that constitutes the largest group below the continental shelf in the NE Atlantic. This seems to be the case also in other seas. Other genera are represented by scattered species of groups normally inhabiting shallow water or the continental shelf. Trophon on the contrary extends from shallow to deep water in high northern or southern areas, while in intermediate latitudes it is restricted to deep water. Genus TROPHON Montfort, 1810 Type species: Murex magellanicus Gmelin, 1791 , by original designation. Several generic names have been proposed for the species we include in Trophon viz.: Trophonopsis Bucquoy, Dautzenberg & Dollfus, 1882. Type species: Murex muricatus Montagu, 1803, by original designation. Boreotrophon P. Fischer, 1884. Type species: Murex clathratus Linne, 1758, by monotypy. Pagodula Monterosato, 1884. Type species: Murex carinatus Bivona, 1832 (= Murex vaginatus De Cristofori & Jan, 1832), by monotypy. Pinon De Gregorio, 1885. Type species: Pinon vaginatus Philippi (sic!), by original designation. Chalmon De Gregorio, 1885. Type species: Chalmon muricatus (Montagu) by original designation. Pinon and Chalmon are thus objective synonyms of Pagodula and Trophonopsis respectively. There are, however, some doubts whether the Recent or the fossil species known under the name Trophon vaginatus should be considered the type species. Recent workers on the genus (Radwin & D’Attilio, 1976; Vokes, 1976; Houart, 1981) have advocated a separation of the southern species usually included in Trophon and the northern ones, which they place in Boreotrophon and Pagodula. (Houart also used the genera Nodulotrophon Habe & Ito, 1965 and Nipponotrophon Kuroda & Habe, 1971 for some NE Atlantic species.) We have examined radulae and opercula of the type species, T. magellanicus, and of all the NE Atlantic species and are not able to separate them into different groups. The species are so variable that they will usually fit equally well into two or more “genera”. It is only T. fabricii that to some degree stands out from the others, by its strongly-shouldered whorls and strong spirabsculpture. It also has a radula that is proportionally longer in relation to the height of the shell. The significance of these characters can, however, not be evaluated until they are known for many more species of the group. The separation of the S American Trophon from the N Atlantic genera has been made only on the basis of unspecified differences in shell morphology and on the grounds that SE American Trophon should have a “purpuroid” operculum, while the NE Atlantic species should have a “muricoid” operculum (Radwin & D’Attilio, 1976, Vokes, 1976). We have figured the operculum of Trophon geversianus and some NE Atlantic species for comparison (Figs 319-327) and although there is a difference in strength of the concentric ridges, this (or any other difference) is not sufficient to divide the S American and NE Atlantic species into two groups. In a comparison of opercula, T. fabricii again stands out, by having a much more distinct pattern. (It should be noticed that opercula of young Trophon are paucispiral cf. Fig. 322.) Comparison of the radulae did not reveal anything except details in the proportions of the cusps (Figs 329-332), differences insufficient to warrant separation. NORTH-EAST ATLANTIC NEOGASTROPODA 127 Neither was a separation based on shell characters possible. Strebel (1905) in his treatment of the S American Trophon shows very well the variation in shell morphology of the genus, from the large, stout forms like geversianus to species like laciniatus (Dillwyn, 1817) that in shell morphology agree well with our NE Atlantic species like T. clathratus. The only remaining difference between the S American and NE Atlantic species (pointed out by Thorson (1946), and to us in a letter by E. Vokes) is the egg capsules. Thorson (1940, 1946) reported that the capsules of T. truncatus and T. clathratus were planoconcavely lens-shaped, with a few embryos, and attached by the flat side to some hard substratum. Jeffreys (1867) described similar egg capsules in T. muricatus. Strebel (1905 & 1920) and Penchaszadeh (1976) reported those of T. geversianus and two other S American species to be lens-shaped and attached by a short broad stalk from the edge. It is impossible to understand what this difference means taxonomically, especially as the spawn is known for very few species. Because of this absence of distinguishing characters we have decided to use Trophon, to include all the NE Atlantic species. The species of Trophon are unusually variable (easily seen from the long lists of synonyms) and it may seem possible to arrange a clade connecting all the different forms if one uses specimens from many different localities. We have, however, found it possible to distinguish nine species (possibly only eight), by the characters listed below. These nine (eight?) species have been examined from all or large parts of their geographic and bathymetric distribution. They typically exhibit a variation from strongly-shouldered and spiny specimens, to more slender forms with weak sculpture (cf. Figs 286-287, 309-312). This variation is usually correlated with a depth or geographical cline, but one can also find local populations with a unique appearance. Two exceptions from this are T. dabneyi and T. droueti, which are fairly constant. A lower degree of variation is consistent with their biology. T. dabneyi is the only NE Atlantic species with planktotrophic larvae, which possibly leads to less local variation and T. droueti is restricted to the continental slopes around the Azores. Distinctive characters of the species Trophon fabricii is an arctic shallow-water species with very distinct spiral sculpture, strongly- shouldered whorls, rather thick and solid axial ribs and usually a crenulated outer lip. Trophon dabneyi has a yellowish, large larval shell of more than two whorls, slender, rounded whorls and low, never spiny ribs. It is a decidedly bathyal species that is never found on the shelf. Trophon droueti has a low spire, rather solid shell, and a thickened flaring outer lip with internal crenulations. It is known from the bathyal area of the Azores. Trophon truncatus is an arctic shallow-water species with rather slender and rounded whorls, rounded larval shell, no spiral sculpture and low, crowded axial lamellae that never form spiny projections. Trophon clathratus is an arctic shallow-water species with a distinctly angulated larval whorl, high, sparse axial ribs that often form spiny projections from the rather low and convex whorls. No spiral sculpture. Trophon clavatus is a boreal species occurring in intermediate depths. It resembles T. clathratus, but has a rounded larval shell and is half the size of T. clathratus. It may have some indication of spiral sculpture, but lacks it normally. Specimens from shallow water often are quite slender, compared with T. clathratus. Trophon barvicensis is a boreal species, possibly reaching the Mediterranean. The shell is greyish to whitish, rather slender, with distinct spiral ribs that give the axial lamellae a fringed appearance. Young specimens may have spiny projections from the lamellae, but we have not seen them in full- grown ones. 128 P. BOUCHET & A. WAREN Trophon muricatus is a rather southern species, reaching northwards to S Great Britain. It usually has a fairly solid, brownish or reddish shell, strong spiral ribs, low and solid axial ribs and a quite slender shape. Trophon echinatus is an extremely variable, southern species that occurs from fairly shallow (100 m) down to the lower bathyal. In shallow water the shell is semitransparent and of a glassy structure, in deep water more chalky. The most characteristic feature is the long slender siphonal canal and distinctly shouldered whorls. Shallow-water specimens lack spiral sculpture, while it is well developed in specimens from deep water. Shallow-water specimens have very well-developed spiny projections from the axial ribs, but they may be lacking in specimens from deep water.

Type material: T. truncatus, lost. Type locality: T. truncatus, N Norway. Material examined : Several hundred shells from all parts of its distribution in the N Atlantic (SMNH, ZMC, MNHN, USNM, coll. AW). Distribution: N Atlantic coastal areas; Parts of Ireland and Scotland (Seaward, 1982), the Kattegat, absent in the Skagerrak and W Norway, common in N Norway (G.O. Sars 1878), the Faroes, Iceland and Greenland (Sparck & Thorson, 1933; Thorson, 1941, 1944, 1951), NE America S to George’s Bank (off Massachusetts) (Abbott 1974). The depths are normally 3 — 150 m, although Golikov (1964) has recorded it from 950 m. Probably panarctic. Remarks: T. truncatus has often been considered a variety or form of T. clathratus, but we consider it a good species. It can be distinguished by its more evenly convex whorls, more numerous axial lamellae and rounded protoconch, from T. clathratus, which has a distinctly angulated initial whorl. Neither does it have any tendencies to form spiny processes from the ribs as clathratus. The specimens figured by Houart (1981, pi. 6, figs 9-10) as Boreotrophon sp. are large specimens of T. truncatus.

Type locality T. clathratus , Icelandic Seas. Material examined: Several hundred shells and specimens from the Swedish west coast (glacial fossils), N Norway, Spitzbergen, Iceland and Greenland (ZMC, SMNH, coll. AW). Distribution: Arctic circumpolar in coastal waters and on the continental shelf. It reaches south to the New England area (Macpherson, 1971), E and W Greenland (Thorson, 1951), Iceland (Oskarsson, 1962), the Faroes (Sparck & Thorson, 1933) and Lofoten (N Norway) (G.O. Sars, 1878). The bathymetric distribution is 4.5 m (Macpherson, 1971) to about 300 m. Remarks: Thorson (1940) described the reproduction. The species has direct development and lens¬ shaped egg capsules. Some attention should, however, be paid to the fact that Oenopota elegans (Turridae) has a very similar larval shell, and we are not aware how Thorson, who identified the capsules from the shells of the embryos, could distinguish between these two species. We have listed Fusus lamellosus Gray as a synonym of T. clathratus . This is not certain, but this will not affect any other name, because the name is preoccupied. We have not examined any Pacific material of T. clathratus , but the names based on such material are all younger than that of Linne, so they will not change it, if they should prove to be based on the same species. The distribution mentioned under that heading is much more arctic than is usually found in the literature. This is because we have distinguished the southern deep-water populations as a distinct species, T. clavatus. For a comparison with that species see p. 130. Some Icelandic specimens seem to have a more rounded protoconch than the typical arctic form, but the specimens are quite worn. Their shells, however, are typical for the arctic form. This point should be examined when better material becomes available. 130 P. BOUCHET & A. WAREN Trophon clavatus G.O. Sars, 1878 Figs 286-290, 322-324, 331, 339 Trophon clavatus G.O. Sars, 1878: 249, pi. 15, fig. 12; pi. 23, fig. 14. Type material: Lectotype and 2 paralectotypes, ZMO D1396 a and b, selected by Houart (1981). Type locality: Lofoten, N Norway, 200-360 m. Material examined: Several thousand specimens from SW Norway and the Swedish west coast, 50 — 500 m, coll. AW; THOR 1903, S of Iceland, probably 1000 m, 3 shs; THOR 1904, st 99, 61° 15 N,09°35 W, 900 m, 1 spm; INGOLF st 90, 64°45 N, 29°06 W, 1000 m, 2 shs; INGOLF st 78, 60°37 N, 27°52 W, 1505 m 1 sh. Distribution: Uncertain, known with certainty only from the material examined, and some specimens determined by G.O. Sars (1878). Remarks: We have decided to keep this species or form separate from T clathratus, as did Houart (1981), although other authors have united it with J. clathratus. The distribution is incompletely known because of this 'Tumping”, but probably some specimens referred to T. clathratus by Sykes (1911) and Massy (1930) from off NW Scotland and Ireland will prove to belong to clavatus. T. clavatus is very common off the W coast of Norway and Sweden, in 50 — 500 m, often together with T. barvicensis (cf. that species), but it seems to be very rare elsewhere. The reasons why we have decided to distinguish between the two species are: 1 . T. clavatus has a distinctly rounded larval shell while that of typical T. clathratus has a distinctly angulated periphery. 2. In Norway typical T. clathratus is restricted to Lofoten and northwards, in 20 — 90 m (G.O. Sars, 1878). This is the large form with angulated larval shell. Further to the south we find the smaller form, with rounded larval shell, and then usually below 100 m with its main distribution between 200 and 500 m. 3. In Iceland typical T. clathratus is common, mainly off the N and NW coasts, in 11 — 260 m (Thorson, 1941; Oskarsson, 1962). It has not been recorded deeper. We have, however, found some specimens in ZMC (see above) from 900 — 1500 m. These belong to the same form as we find in deep water in Scandinavia, although they have a tendency to be still more spiny (Fig. 286). 4. In the Faroes typical T. clathratus is known from 8 — 50 m (Sparck & Thorson, 1933). The clavatus form is not known from there. 5. T. clathratus in its typical form is common along the coasts of Greenland and E Canada, S to Maine, in shallow water (30 100 m, Verrill, 1882), while in deep water we find Trophon abyssorum Verrill, 1885, with a more southern distribution. The clavatus form is not known here. Therefore we suppose that two species, (or at least subspecies) have been confused; the more or less panarctic T. clathratus » and T. clavatus with a rather restricted distribution in the NE Atlantic. G.O. Sars (1878) was not aware of this when he described T. clavatus , because he used the name for some extremely large specimens with a typical appearance, while he regarded the S Scandinavian specimens from deep water as a small form of T. clathratus. As our figures illustrate, T. clavatus is quite variable. Some specimens resemble T. barvicensis closely, but we have noticed this only in young specimens, when sometimes T. barvicensis has a poorly-developed sculpture and T. clavatus may show some undulations in the axial lamellae. We have never had any difficulties in separating half-grown or larger specimens. Neither have we had any problems separating T. clavatus from T. clathratus, but that may be because we have not been able to examine more than a few specimens from areas where both species occur. NORTH-EAST ATLANTIC NEOGASTROPODA 131 Trophon barvicensis (Johnston, 1825) Figs 291-296, 341 Fusus barvicensis Johnston, 1825:221. Type material : Not known. Type locality: Near Berwick, NE England. Material examined: Several thousand specimens from S Norway and the Swedish W coast, coll. AW; a few hundred shells and specimens from the British Isles, the French W coast and Iceland, MNHN, USNM, ZMC; some doubtful specimens from the Mediterranean, private collections, MNHN, USNM; off Morocco, a few shells, MNHN. Distribution : From W Finmark, N Norway (G.O. Sars, 1878), Iceland (Thorson, 1941), southwards on the shelf and in coastal waters to off Morocco (Locard, 1897), where it occurs in the upper bathyal zone. Remarks: T, barvicensis is often very common on the shelf off S Norway, where it occurs together with T. clavatus in large numbers. Some young specimens may then be difficult to distinguish from that species, but they are quite rare and can be separated by having a microsculpture of scattered tubercles on the protoconch, while T. barvicensis has these tubercles arranged in lines. We have not seen any unquestionable Mediterranean specimens. Some specimens reported on by Di Geronimo & Panetta (1973) and Franchini & Frilli (1970), determined as T. richardi, resemble T. barvicensis closely, but we have seen all interrmediates between these specimens and T. muricatus from closely-situated localities. (Similar observations have been made by Chaster (1898) and Chaster & Heathcote (1894) in the British Isles.) Therefore we are not certain if T, barvicensis lives in the Mediterranean. The question arises that T. barvicensis may be only a deep-water form of T. muricatus, an assumption that is supported by the doubts expressed by Chaster (1898). However, in Scandinavia barvicensis occurs more shallowly, from 50 m, thus occupying depths where muricatus should be expected, yet barvicensis does not change form. The problem can, however, not be considered settled. Some specimens from the Azores ( Trophon sp., p. 131, Fig. 297) resemble T. barvicensis closely, but have more convex larval whorls, they are more spiny and occasionally have a coloured shell. This may be a local form of barvicensis, but because of the differences mentioned above and the geographical separation, we prefer to keep it separate, at least until we know if T. barvicensis occurs on any of the intermediate sea-mounts.

Remarks: We have only seen four specimens of this form of Trophon, all from the Azores. It differs from T. droueti, which occurs in the same area and the same depths, by being more slender and having stronger projecting spines on the shoulder of the whorls. We have not seen any intermediates between the two. There is a possibility that this is a form of barvicensis, but as nothing is known about the occurrence of barvicensis on the sea-mounts between the Azores and Europe, it cannot be discussed. 132 P.

Distribution: European coastal areas, from Great Britain south to the Mediterranean and Morocco, in 20 — 300 m. Remarks: Several authors (Franchini & Frilli, 1970; Houart, 1981) have recently synonymized T. barvicensis and T. muricatus. As we have discussed under T. barvicensis we do not find the evidence for this convincing enough. We have seen samples with the two forms occurring sympatrically, from the Bay of Biscay and N Morocco, from 120-200m. We have, however, also seen samples where it seems impossible to distinguish the two (e.g. from the Adriatic, coll. G. Spada, Bologna). The Mediterranean material we have seen has been insufficient to ascertain whether barvicensis really occurs in the Mediterranean and the problems are caused by a higher variability of muricatus there, or if they really integrade. The latter seems to be supported by Chaster’s (1898) observation that they intergrade in the British Isles, but contradicted by our observations from other areas. Therefore we prefer to leave the question open and treat them as two species. Jeffreys (1867), Lebour (1936) and Fioroni (1966) have described the egg capsules, which are lens¬ shaped and attached to some hard substratum. The Black Sea form, breviatus, is probably worth subspecific status. It has been figured by Houart (1981) and Waren (1980). NORTH-EAST ATLANTIC NTOdASTROPODA 135 Figs 298-301. Trophon muricatus. 298.

It has been found in 6 — 160 m. Remarks: T. fabricii is not a deep-water species, but has been included to complete the genus.

Distribution: Endemic to the bathyal area of the Azores; known only from the material examined. Remarks: As already noticed by Houart (1981) the name richardi ( = droueti) has recently been used by Mediterranean authors for shelf populations of T. muricatus or T. banicensis. T. droueti can be distinguished from these populations by its broader outlines and its aperture, furnished with denticles on the inside of the outer lip. The development of spines from the axial lamellae is variable in the two forms and cannot be used for separation. There is, however, some possibility that T. droueti should be considered only an isolated population or subspecies of barvicensis, which certainly is its closest relative. At present nothing is known about the occurrence of barvicensis or droueti on the sea-mounts between the Azores and Europe, which prohibits further speculation on the relationship.

Distribution: The bathyal parts of the Eastern Atlantic, from the northern part of the Bay of Biscay to the Cape Verde Islands and Azores. Remarks: T. dabneyi can be recognized from its multispiral, brownish larval shell which indicates planktotrophic larval development. It is the only species, in the area studied, with such larvae. The protoconch, however, is frequently corroded in adult specimens and the species becomes difficult to distinguish from T. echinatus (the cossmanni “form”). Distinctive characters then, are the more blunt spire, less distinct spiral sculpture and less shouldered axial lamellae in T. dabneyi.

Also present in the bathyal zone of the Azores {cossmanni “form”). 138 P. BOUCHET & A. WAREN Remarks on the nomenclature The present species is usually known as Trophon vaginatus (De Cristofori & Jan, 1832), as far as specimens from the shelf are concerned. We have examined the lectotype in Museo Civico di Storia Naturale, Milano. It was described as a Pliocene fossil from Tabiano, N. Italy. It is certainly quite similar to the Recent Mediterranean form (Fig. 314 and Pinna, 1971, pi. 77, fig. 6), but there is a distinct difference in the larval shell, which in the Recent form consists of about 1 .5 whorls (Fig. 316) while the Pliocene form has more than 2.5 whorls (Fig. 315), and possibly had planktotrophic larval development. This observation was confirmed by examining numerous specimens from other N Italian Pliocene deposits (in the rich collection of Della Bella). We therefore consider the Recent form specifically distinct from the Pliocene fossil. The two subsequent names Murex carinatus Bivona, 1832 and Murex calcar Scacchi, 1836 which have been used for the Recent Mediterranean form, are both based on N Italian Pliocene specimens and also preoccupied, and thus not available. Fusus echinatus Kiener, 1840 was based on Recent specimens and well figured. There are no doubts about its identity. The case is, however, complicated by Sowerby’s (1818) use of the name Murex echinatus. Sowerby’s species was transferred to Fusus by Fleming (1828) and Philippi (1836) and is in fact a synonym of Trophon muricatus (Montagu, 1803). In the description, however, Sowerby writes “Syn, Murex echinatus Brocchi, 2, 423, t. 8, f. 3”. Rossi-Ronchetti (1955) considered M. echinatus Brocchi to be a species of Philbertia (Turridae) which probably is correct. Therefore Sowerby’s use of the name is based on a misidentification and has no taxonomical status and does not make Trophon echinatus preoccupied. Several later names reflect the high variability of T. echinatus. Remarks on the variation Trophon echinatus exhibits considerable variation, especially in relation to depth. The Mediterranean and the Atlantic shelf form do not differ very much. They have a porcellaneous, smooth, very slender and spiny shell (Figs 312-313), without spiral sculpture. Sometimes the Mediterranean form is a little more slender and spiny, but not enough to cause any problems with the identification. At the uppermost part of the continental slope there is a tendency to more numerous but less spiny axial lamellae. Typical specimens of this form have been called grimaldii Dautzenberg & Fischer in the Atlantic and multilamellosa Philippi in the Mediterranean. Still deeper, in the Atlantic in 600-1000 m, the spiral sculpture starts to become conspicuous and the spines are still less developed (Figs 308-309). This form is known as cossmanni Locard and has been found down to 3000 m. Franchini & Frilli (1970) considered grimaldii a subspecies of “ carinata de Cristofori & Jan” ( = T. echinatus) (and considered “ multilamellosa Philippi” a distinct species). To discuss this one has to keep in mind that the typical T. echinatus has a continuous distribution along the shelf, via the Straits of Gibraltar, and there exists one Atlantic and one Mediterranean deep-water outcrop of the species. The bathymetric variation in shell form of these two outcrops is identical, except that the cossmanni form is very scarce and perhaps extinct in the Mediterranean. Only a few old shells are known. Therefore we prefer to regard the variation not as a result of genetic isolation (subspecies), but as more directly influenced by the depth. It would be more than pure coincidence if the Atlantic and Mediterranean deep populations had diverged from the shallow-water form because of genetic isolation in exactly the same way in the two outcrops. Therefore we prefer to call them simply different “forms”, viz. typical echinatus (Figs 312-313), the grimaldii “form” (Figs 310-311) and the cossmanni “form” (Figs 308-309). NORTH-EAST ATLANTIC NEOGASTROPODA 139 Comparison with other Atlantic species of Trophon The sculpture of T. echinatus is variable and this does not facilitate identification. A few features are, however, quite constant: paucispiral larval shell, long slender siphonal canal and strongly- shouldered whorls. T. dabneyi has a larval shell of 2.5 brownish whorls while that of echinatus has 1.5 whorls and is colourless. It also has more rounded whorls and more solid, rib-like axial sculpture, not thin lamellae as echinatus. T. droueti has a shorter siphonal canal and more pronounced spiral sculpture, approximately as strong as the axial one. T. barvicensis has a shorter siphonal canal, stronger spiral sculpture and a higher shoulder of the whorls. The Caribbean T. aculeatus Watson, 1883 (= lacunella Dali, 1889) resembles T. echinatus, especially specimens from intermediate depths, but is higher, more slender and has a deeper suture than echinatus. We have not seen specimens of aculeatus with spiral sculpture. T. abyssorum Verrill, 1885 (? = limicola Dali, 1902) resembles the cossmanni “form”, in the shape of the shell and the sculpture. It is known from off the NE U.S. from 1500 to 3500 m. The available material of that species, however, is scanty and there is a large gap in the distribution in the N Atlantic, from Rockall to U.S., where no Trophon species related to these species are known. Therefore we find it better to keep them separate. More problems arise when going further south. Trophon guineensis Thiele was described from the Gulf of Guinea (03° 10 N, 05°28 E, 2278 m). The larval shell is not known, but the postlarval shell can hardly be distinguished from the cossmanni “form”. We have examined two specimens from off Angola (WALDA st CY15, 10°30 S, 11°55 E, 1756 m). The shell is identical, but the larval shell is destroyed. One of the specimens was a female and had a couple of egg clusters, 1100-1250 diameter and containing a few hundred eggs each, of a diameter of 120 fim. These egg clusters were kept in the pallial cavity. The diameter of the eggs indicates planktonic larval development, because the diameter of the eggs of species of Trophon with direct development is 230 — 500 \xm (5 species known). This female also differed from T. echinatus in having unpigmented eyes, while T. echinatus has black eyes. Further to the south we have examined many specimens from the sides of the Walvis Ridge (WALVIS st CP13, 32°18 S, 13°16 E, 3550 m and CP 14, 32°29 S, 13°25 E, 3675 m). They were all heavily encrusted by zoantharians and the larval shells were badly corroded. They had normal eyes, but no eggs were observed. They resemble T. acceptans Barnard, 1959 (see also 1963), described from 33°34 S, 1160 — 3275 m. Barnard (1963) doubted the validity of this species and said “I fully expect that acceptans will not be accepted when further material is obtained from the Atlantic trough along the west coast of Africa”. It is still impossible to say anything about the validity of these two names, but the differences in the development of the eyes indicate that they may not be synonyms. 140 P. BOUCHET & A.

NORTH-EAST ATLANTIC NEOGASTROPODA 147 Genus PTERYNOTUS Swainson, 1833 Type species: Murex pinnatus Swainson, 1822, by original designation (pi. 122). Remarks: The genus Pterynotus and its subgenera have been discussed by Ponder (1972) and the W Atlantic species were monographed by Harasewych & Jensen (1979). There are two species of the genus in the Central E and NE Atlantic, P. leucas Locard and P. atiantideus which is described here. They can easily be separated by the presence of intervarical nodes or bulges in P. atiantideus, easily seen in an apical view (cf. Figs 350, 353). These bulges are absent in P. leucas . Figs 348-350 Pterynotus atiantideus n.sp. Type material: Hoiotype in MNHN. Type locality : BIACORES st 186, 37°51 N, 25°40 W, 370-455 m. Material examined: The type material and BIACORES st 38, 37°59 N, 29° 16 W, 350-400 m, 1 spm; st 146, 37° 39 1 sh; st 236, 37°21 N, 25°45 W, 470-500 m, 1 spm. Distribution: In addition to the material from the Azores enumerated above, P. atiantideus is known from the Great Meteor Bank, in 295-343 m (Fechter, 1977 as P. leucas ). Description: Shell solid, fusiform, consisting of six postlarval whorls, larval shell white, consisting of one smooth whorl. The first postlarval whorl has 7 fragile foliaceous varices that adhere to the protoconch; there is no intervarical node between these early varices. The regular adult sculpture starts on the second whorl and there are 3 varices and 3 intervarical nodes per whorl. The spiral sculpture consists of spiral cords, of which a few stronger ones extend on to the varices where they tend to produce spines; there are also extremely fine spiral threads which, together with the fine axial sculpture present on some specimens (including the hoiotype), may give a reticulate appearance under high magnification. Aperture oval, outer lip with 7 denticles; siphonal canal of moderate length for the genus, open; colour light tan with a few brownish blotches on the varices or the nodes; aperture white. Dimensions : Height of the shell 21 mm, breadth 11 mm. Remarks : P. atiantideus differs from P, leucas in its smaller larval shell, by having intervarical nodes and by its coloured shell. In P. leucas » there are several postlarval whorls with numerous varices (Fechter, 1977: fig. 11), while there are only 1 to 1.5 such whorls in P. atiantideus. P. leucas also reaches a larger size.

Remarks: We have included P. leucas for comparison with atiantideus although it lives outside the area covered by this series. It has not been found since the original description. The record in Fechter (1977) is based on P. atiantideus. 148 P. BOUCHET & A. WAREN Figs 348-353.

Genus ORANIA Pallary, 1900 Type species: Murex spadae Libassi, 1859, by original designation. Synonym: Nemofusus Cossmann, 1903. Type species: Murex fusulus Brocchi, 1814, by original designation. Remarks: We have kept the generic name Orania for Murex fusulus Brocchi. This species has usually been referred to Pseudomurex or Urosalpinx. It also resembles Ocinebrina and Muricopsis. Pseudomurex belongs to Coralliophilidae and has no radula, while fusulus has one. Urosalpinx differs considerably in radular characters and shell characters. Ocinebrina and Muricopsis have quite similar shells, compared with fusulus , but have a very distinct radula (Figs 345-346). (It should here be pointed out that the radula of Ocinebrina aciculata Lamarck (type species of Ocinebrina) was figured by Radwin & D‘Attilio 1976, but their figure differs considerably from what we have seen.) We know of no other genus in common use where fusulus fits, and have therefore kept Pallary’s genus, which was not included by Radwin & D’Attilio (1976). Lack of any well-fitting genus has also induced us to place grayi here, although it also resembles Cytharomorula Kuroda, 1953. Pallary (1900) designated Murex spadae Libassi as type species, when describing the new genus Orania. There exists some doubt about the identity of spadae which was described as a Pliocene fossil (Kobelt 1887), but evidently Pallary introduced the new generic name for the Recent form, which should be considered the type species if more than one species proves to be involved. 150 P.

Italy; M. pyrrhias, CHALLENGER st. 75, 38°38 N, 28°28 W, 830-920 m. Material examined: The types listed and about 75 specimens and shells from the Bay of Biscay (northernmost record 45°43 N, 02° 14 W, 160 m, 2 spms) to the Cape Verde Peninsula (95 — - 200 m) and Tristao (Guinea) in the south (MNHN), the Azores and the western Mediterranean, where it seems to be rather common off the N African coast. Distribution: The western parts of the Mediterranean, from Sicily (Monterosato, 1890), Corsica (Locard & Caziot, 1901), Oran, Algeria (Pallary, 1900), westwards to the Atlantic, where the extremes are given in “Material examined”. It is known from 35-440 m. Remarks: Murex fusulus has often been placed in Pseudomurex (Coralliophilidae), but it has a radula so it fits better in the Muricidae. This was already noticed by Kobelt (1887), but has not been mentioned by most later authors. Orania fusulus has a smooth, multispiral larval shell, which indicates planktotrophic larval development. When this paper was in press, the work by Sabelli & Tommasini (1983) was published, with anatomical datas. Orania grayi (Dali, 1889) Figs 344, 356 Nassarina grayi Dali, 1889:183, pi. 32, fig. 12a.

Distribution: Known from the Caribbean area, 100 — 200 m (Abbott, 1974) and some sea mounts and islands in the E Atlantic. Not known from European or African coasts. Remarks: O. grayi was transferred to Muricidae by Radwin & D’Attilio (1976) who placed it in Evokesia Radwin & D’Attilio, 1972. We have, however, preferred to place it in the same genus as O. fusulus. The larval shell is multispiral and indicates a planktotrophic larval development, which possibly contributes to the scattered distribution. NORTH-EAST ATLANTIC NEOGASTROPODA 151 Family CORALLIOPHILIDAE The taxonomy of the family Coralliophilidae is at present in a state of confusion, presumably because attention has been focused on the many extreme-looking species that represent the most far- reaching sprouts of the evolutionary tree, and give the least information about relations within the family. We have therefore not made any attempts to divide the species treated here into different genera, but use the generic name Coralliophila for all. We shall, however, give some nomenclatorial remarks on the generic names that have been in use for the NE Atlantic species. Pseudomurex Monterosato, 1872 is the most often used name. D’Attilio (1978) and other authors have considered Murex bracteatus Brocchi, 1814, to be the type species, but Monterosato only included two species in his genus, viz. Murex lamellosus Jan (sic!) and Murex spadae Libassi. Later he restricted the genus to include only M. lamellosus and transferred M. spadae to Pollia. M. spadae is a muricid and is discussed on p. 150. Therefore Dautzenberg (1927) was correct when he designated Fusus lamellosus Philippi as type species of Pseudomurex. Aradomurex Coen, 1943. Type species, Murex so fiae Aradas & Benoit, 1876. Babelomurex Coen, 1922. Type species, Fusus babelis Requien, 1849. Fusomurex Coen, 1922. Type species, Murex alucoides de Blainville, 1829 (not Olivi, 1792). A synonym of Pseudomurex. Hirtomurex Coen, 1922. Type species, Fusus lamellosus Philippi, 1836. Latimurex Coen, 1922. Type species, Murex meyendorffi Calcara, 1845. Lepadomurex Coen, 1922. Type species, Purpura brevis de Blainville, 1832. The species of Coralliophilidae live as parasites or predators on anthozoans. Coralliophila brevis has been found on at least three species of gorgonian ( Paramuricea chamaeleon, Eunicella stricta and Lophogorgia sarmentosa) and C. meyendorffi has been found on Anemonia sulcata and Cladocora cespitosa (G. Spada, pers. comm.), so evidently they are not very host specific. The species are quite rare in deep water, below the continental shelf, which makes a treatment of these species more difficult. The Mediterranean shallow-water species were discussed by Sabelli & Spada (1980) in a very useful paper, and by Settepassi (1977) who lists 14 names of specific rank and a multitude of lower ranking names. We have examined the larval shells of all species discussed here except C. sentix. They proved to have a multispiral larval shell, of very uniform shape and sculpture (Figs 370-371, also Richter & Thorson 1975, figs 70-71). Because of the uniformity and also because it is normally corroded, even in young specimens, the larval shell is of almost no use for taxonomical purposes. Pleurotomoides obliquispira Nordsieck, 1977, is based on a juvenile of a species of Coralliophilidae, but we are not able to say which species. 152 P. BOUCHET & A. WAREN Genus CORA LLIOPHILA H. & A.

Distribution: Both sides of the subtropical North Atlantic, in the upper bathyal zone. The species has been reported in the Mediterranean by Monterosato (1890:23), Taviani & Colantoni (1979:141), and Sabelli & Spada (1980:2) from empty shells. The species probably lives associated with Cnidaria of the Lophelia- reefs and is possibly now extinct in the Mediterranean. Remarks: C. richardi is the most characteristic of the NE Atlantic species of Corailiophiia. The axial sculpture consists of lamellose varices instead of solid ribs as in the other species. These lamellae are given a slightly fringed appearance by the spiral sculpture. It lacks the fine, squamulose sculpture characteristic of many species of the family. Corailiophiia panormitana (Monterosato, 1 869) Fig. 369 Pyrula panormitana Monterosato, 1869: 17, fig. 9. Type material: Not seen. Type locality: Palermo, Sicily. Material examined: About 20 spms from the Western Mediterranean and TALISMAN dr 63-64, 26° 17 N, 14°52 W, 355-640 m, 1 spm. Remarks: We have seen only one specimen from the Atlantic, but that one is very large in comparison with W Mediterranean specimens. It closely resembles, however, an unusually large specimen from the continental shelf off Mdiq (S Alboran.Sea, coll.S.Gofas). C. panormitana can be distinguished from C squamosa and C. basileus by having a more inflated body whorl.

Distribution: From the bay of Biscay, along the Iberian peninsula, 'the Mediterranean, NW Africa to the Canaries and the Azores. It occurs mainly on the continental shelf and in coastal water, but has occasionally been found on the upper part of the continental slope. Possibly also in the Caribbean area (Bayer 1971). Remarks: The present species has usually been known under the names alucoides de Blainville, 1830 and lamellosus de Cristofori & Jan in Philippi, 1836. Both these names are, however, preoccupied, as is also the third name suggested by Philippi (1836). The name Fusus squamosus Bivona, 1838 is not preoccupied, but the description and figure are not very good. To avoid this problem we have selected a neotype from Corsica that agrees fairly well with Bivona’s figure. Another name that has been in use for the present species is bracteatus Brocchi, 1814. The name was based on a Pliocene fossil. The type has been figured by Rossi-Ronchetti (1955), Pinna & Spezia (1978) and we have personally examined it in Museo Civico di Storia Naturale, Milano; we find it more like the Recent W African C. angolensis Knudsen. We think that Knudsen’s species is the Recent descendant of C. bracteata, as is the case for many other Italian Pliocene species, the descendants of which now live in W Africa. The names introduced by Settepassi (1977) need no comments. C. squamosa occurs in coastal waters and on the shelf in the Mediterranean (but seems to be absent from the continental slopes). Such specimens are characterized by having a strongly squamose sculpture, well-defined siphonal canal and a rather high spire. Atlantic specimens have a broader and more open siphonal canal and reach a larger size (50 mm instead of 40 mm maximum size). In these respects the Atlantic form approaches fossil shells from old coral associations in the Mediterranean, reported by Taviani & Colantoni (1979). For a discussion of basileus, see that species, and for separation from the Mediterranean shallow- water species, see Sabelli & Spada (1980). Bayer (1971) reported C. lamellosa ( = squamosa) from the Caribbean area and synonymized it with Trophon lintoni Verrill & Smith, 1882. We have examined this and additional material in USNM. We agree that there are specimens that closely resemble squamosa, although the specimen figured by Bayer (fig. 51) more closely resembles basileus. Other facts also, like the occurrence at the Azores and the presence of planktotrophic larvae, suggest an amphiatlantic distribution, but the chaotic state of the taxonomy of the Caribbean Coraliiophilidae makes it impossible to coordinate the names of the species without a complete revision of the W Atlantic species. 154 P.

Distribution: The upper part of the continental slope around the Azores and the Canaries. Remarks: We are not convinced that basileus is truly distinct from squamosus, but as we have no definite proof we have preferred to keep them distinct. There is a difference in shape, basileus having a broader siphonal canal that is less set off from the aperture, and in size, basileus barely exceeding half the size of squamosus. There is also a difference in distribution. C. basileus occurs only around the Azores and the Canaries, while it is not known from the E Atlantic coasts. C. squamosus also occurs around these islands, but its main distribution is Mediterranean and along the S European and N African coasts. The two forms thus occur sympatrically in the Atlantic islands, but we have not seen specimens of both forms in a single dredge haul (except a TALISMAN sample, from several stations), which indicates some degree of separation. The two forms are very variable and we have not examined very large numbers, so we prefer to leave the question of conspecificity unsettled. A second possibility, although we find it less probable, is that C. basileus is a local form of C. brevis (de Blainville, 1826). That species, however, has a thinner shell and the aperture, at least in adult specimens, is deformed by its sessile life on gorgonians, which we never have seen in basileus.

Remarks: Specimens from the W Atlantic have longer and more developed shoulder projections that join each other more extensively than those from the E Atlantic. We have, however, considered them conspecific. C. fax Bayer, 1971, from off Florida, has the same type of non-squamose sculpture as C. sentix, but has a broader shape, lower spire and a smoother shell. In the Atlantic only C. juliae Clench & Aguayo, 1939 shares the rather high spire and non-squamose sculpture, but it has more or less open coiling. No other Atlantic coralliophilid can be confused with them. NORTH-EAST ATLANTIC NEOGASTROPODA 155 Figs 357-361 .

See also “Remarks”. Distribution : The upper bathyal of West Africa, from Namibia to Senegal at least; doubtful records further to the north (see below). Remarks : Although the type material of N. sadurnii has never been figured and we have not examined it, there is no doubt that the name is a synonym of wolffi . In a letter of November 1975 Mr J. Bot informed us that his species is very close to Nassa wolffi Knudsen. He said he had seen material from Angola with all the characters of sadurnii. The same species was again described by Maldonado (1973) from specimens taken by shrimp trawlers. In the same paper, Ghisotti & Spada argued that the description of Nassa sadurnii Bot did not meet the requirements of ICZN because it was not accompanied by an illustration. At the same time (p. 234) they “provisionally name” Maldonado’s material Hinia frigens malacitanae n.ssp. “until further material can be studied for a definitive identification”. In fact Bot’s description is perfectly valid, while Ghisotti & Spada do not fulfil the requirements of ICZN §15 which states that “after 1960, a new name proposed conditionally (...) is not available”. N. wolffi has been recorded a few times from the W Mediterranean, but all records are based on specimens with unreliable locality information, taken by fishing boats and said to come from the Alboran Sea and the fishing grounds off Catalonia. It is possible that the species occurs in the W Mediterranean, but the records need confirmation. N. wolffi has a smooth larval shell of 2.5 whorls, which indicates planktotrophic larval development.

Distribution: Beside the material cited above, the species is known from Angola, in 225-750 m (Adam & Knudsen 1955:10). Remarks: All the shells have corroded apices, so the type of larval development is not known. We have not examined the type of N. frigens , but our material fits with the specimens figured and described by Adam & Knudsen (1955) who had examined the type. N. frigens bears some resemblance to Profundinassa Thiele, 1929 (type species Nassa babylonica Watson, from the bathyal zone of the Philippines). Typical species of Profundinassa are present in the Pliocene of Sicily (Moroni & Torre 1966:32, pi. 1, fig. 7). 160 P. BOUCHET & A. WAREN Family FASCIOLARIIDAE We follow Ponder (1973) and include the “fusinid” genera in Fasciolariidae. Several genera have been proposed for the shallow water species of S Europe: Aptyxis Troschel, 1868. Type species Fusus syracusanus Linne. Gracilipurpura Jousseaume, 1880. Type species Fusus strigosus Lamarck (= rostratus Olivi, 1792, not Solander in Brander, 1766). Pseudofusus Monterosato, 1884. Type species Murex rostratus Olivi, 1792, here designated. Sinistralia H. & A. Adams, 1853. Type species Murex maroccensis Gmelin. We figure the radulae for the type species of these genera (figs 380, 381, 385). Of these it is only Aptyxis that shows any difference in the central tooth, which has longer and#more slender cusps. This genus also differs in its shell characters and could probably be kept as a subgenus. We consider the other genera synonyms of Fusinus Rafinesque, 1815. The family has very few species in deep water in the NE Atlantic. We recognize three species, but the names below need some comments. Clathurella rugosissima Locard, 1897. The holotype in MNHN is an extremely worn old shell, probably a Lathyrus, but too poor to be identified. It is probably a shallow-water species. Pseudofusus gigliolii Monterosato, 1890. The species was described from specimens taken by the WASHINGTON expedition, without any information about the locality, but the expedition dredged around Sardinia and Sicily. Nothing is mentioned about this name by D’Amico (1912), who prepared a report on the Mollusca. The type material could not be found in ZMR, although it was figured by Franchini & Zanca (1977). We have however examined specimens taken by the MONACO expeditions and the geological cruises of BANNOCK (in Istituto di Geologia, Bologna), that correspond with Monterosato’ s description and the figures of Franchini & Zanca. From this we conclude that gigliolii was based on the same white, slightly-keeled, deep-water form of rostratus as bengasiensis. Fusus bengasiensis Sturany, 1896. We have examined the holotype in Naturhistorisches Museum, Wien. It is an old, broken specimen of a form of Fusinus rostratus , known as var. carinata Monterosato in Bucquoy, Dautzenberg & Dollfus, 1882. Pseudofusus locardi Pallary, 1904, is based on Locard ’s figures (1897, pi. 16, figs 26-30) of ‘Fusus rusticulus Monterosato”. The specimen came from 530 m, off Morocco. Examination of the specimen in question showed that it is a specimen of F. rostratus . It may be mentioned here that the name Murex rostratus Olivi 1792 actually is preoccupied by Solander in Brander’s use of the name (1766). The next name available seems to be Murex sanctaeluciae von Salis, 1793, but a change of name should not be done until the shallow-water species are carefully revised, to avoid unnecessary name changes. The genus Troschelia, which usually has been placed in Fasciolariidae, is here regarded to belong to Buccinidae. Genus FUSINUS Rafinesque, 1815 New name for Fusus Lamarck, 1799, not Helbling, 1779. Type species: Murex colus Linne, 1758, subsequent designation by Schumacher, 1817. Remarks. See remarks on the family. Fusinus bocagei (P.

Distribution: The upper part of the continental slope, from the Bay of Biscay, south to the Cape Verde Islands and the Azores. Unkown in the Mediterranean. Remarks: Fusinus sectus (Locard, 1897) from 882 m, off Mauretania is probably a distinct species. The whorls increase their diameter more rapidly, there are more numerous axial fibs and the siphonal canal is distinctly curved in that species. It is known from the holotype only. Its larval shell is too corroded to allow examination. The animal of F. bocagei has eyes. The larval shell consists of three whorls, the last with indistinct axial ribs, and indicates planktotrophic larval development. The species here called Fusinus sp. and also F. rostratus can be distinguished from F. bocagei by having a paucispiral larval shell.

Remarks: F. amiantus can be distinguished from F. bocagei, by having much finer spiral sculpture and by having more pointed knobs on the axial ribs. Also the larval shells differ: F. amiantus has more distinct axial ribs and 2 or 3 spiral cords just above the suture, instead of a single cord as in F. bocagei. 162 P. BOUCHET & A.

Remarks: Locard considered the specimens listed above to be Fusinus gigliolii (Monterosato). We consider F. gigliolii a deep-water form of F. rostratus (Olivi), but find Locard’s specimens to differ from any F. rostratus we have examined, in having a larger larval shell and more regularly convex whorls, a more slender spire and a more curved siphonal canal. The specific distinction is supported by the fact that F. rostratus was found at st 39, (listed by Locard under the name Fusus rusticulus Monterosato and later named Pseudojusus locardi Pallary, 1904) together with Fusinus sp. The diameter of the larval shell of Fusinus sp. is 1.3 — 1.4 mm, while F. rostratus varies from normally 700 pm, up to 1.2 mm (in deep-water specimens). We prefer to leave this form undescribed until more material is known.

Material examined: The types of haliaeeti, grimaldii and nicolayi; over 1500 spms from all parts of the distribution area, USNM, MNHN, BMNH, ZMC. Distribution: From the Lofoten Is. southwards on the outer banks off the Norwegian coast in 150-700 m; along the continental slope of the British Isles, the Bay of Biscay and south to 31°43 N (MONACO st 116); the bathyal of the Mediterranean and the Azores; S of Iceland (Thorson 1941:75, and INGOLF material in ZMC); also off northern N America south to North Carolina. Remarks: The present species has usually been known under the name Amphissa costulata or A. haliaeeti . The name of Cantraine (1835) is however preoccupied by Fusus costulatus Lamarck, 1822. The second available name, B. acutecostatum was used by Locard (1897) without any comments, although Watson (1886) who had received specimens supposed to be acutecostatum from Seguenza, wrote that he had “no doubts that the Buccinum acutecostatum is not the Columbella haliaeeti Jeffreys”. Dautzenberg (1927) on the contrary, said he could see no differences between Recent specimens and fossil acutecostata that he had received from Monterosato. He apparently used the name costulata because it escaped his notice that it was preoccupied. None of these authors figured any fossil specimens to support their conclusions. Through the kindness of S. Palazzi, we have been able to examine fossil specimens from S Italy (Boretto) that agree well with Philippi’s description and occur in deposits having a similar fauna as Philippi’s specimens. Fig. 398 shows the larval shell of such a specimen. We have not been able to find any difference from Recent specimens and conclude that acutecostatum is the correct name for the Recent species too. 166 P. BOUCHET & A. WAREN Figs 391-394.

A. acutecostata is a rather variable species. Mediterranean specimens tend to be uniformly rather solid, in shallow water with blotches of light tan. Atlantic specimens are white or greyish and the solidity of the shell is variable. The development of the axial ribs is variable, even in a single population. The larval shell is multispiral and has an elaborate sculpture (Fig. 397). It has been figured by Bouchet (1977) and Bouchet & Waren (1979) as A haliaeeti. Simroth (1895) and Richter & Thorson (1975) obtained the larva in plankton (described as C. haliaeeti and species 4 respectively). Bouchet & Fontes (1981) examined the isotope composition of the larval shell and concluded that the larval shell had been formed in more shallow water than the postlarval shell.

Remarks: M. nitidulina is closely related to Astyris profundi Dali, 1889 from the western Atlantic basin, but is broader, has smaller apertural teeth and coarser incremental lines. M. nitidulina also has a more inflated larval shell and lacks the characteristic axial and spiral microsculpture of profundi. The protoconch is multispiral and has an elaborate sculpture, indicating planktotrophic larvae. Mitrella sp. Fig. 402 A single worn shell of another Mitrella species was taken at BIACORES st 101, 39°23 N, 31°05 W, 843-900 m. It is a broken shell in poor condition (Fig. 402) but shows some resemblance to Astyris profundi Dali, 1889 (Fig. 401). The specimens, however, are too few to allow certain identification because of the often very minute differences between columbellids. Genus ANACHIS H. & A.

BOUCHET & A. WAREN Family BUCCINIDAE Most previous workers on the family have divided it into several subfamilies or families (Cossmann, 1901 ; Wenz 1941; Golikov & Starobogatov, 1975; Habe & Sato, 1973; Kantor, 1981), while Ponder (1973) united Buccinidae, Fasciolariidae, Nassariidae, and Melongenidae to a single family, Buccinidae, and considered the former families subfamilies. Our experience from genera like Kryptos, Troschelia and Belomitra supports Ponder’s view. We have, however, kept the old families for some genera of typical Fasciolariidae and Nassariidae, but placed the doubtful genera in Buccinidae. The taxonomy of the N Atlantic buccinids has been found confused and in order to reduce the confusion we have included a number of shallow-water species and W Atlantic species from N Carolina and northwards. Below we discuss some of the taxonomic criteria we have used and give a provisional key to the N Atlantic genera. Larval shell. The larval development of Buccinum undatum and Colus stimpsoni has been described in detail (Portmann, 1925, 1930; West, 1973). Several hundred to several thousand eggs are laid in each capsule. A few of these develop to shell-less veligers. These ingest further eggs and store them in the digestive tract, which thus acts as a yolk sac. In B. undatum (Portmann, 1925) and Colus gracilis (own observations) the shell is formed rather late in the development and takes a shape according to the shape of the visceral sac, which varies depending on how many nurse eggs the larva has eaten. In some specimens of C. gracilis we noticed that the formation of the shell started with the lower parts and the apical part was the last to be formed. After the shell has been formed, normal “postlarval” growth starts, while the larva still lives in the egg capsule, feeding on less developed embryos. Fig. 588 shows larvae from capsules where these two stages can be seen. In C. stimpsoni a larval shell is said to develop rather early, but the apical part is later thrown off, leaving a scar where it has been attached (West, 1973). We have not noticed this scar in perfect protoconchs of C. stimpsoni. In other species the larva starts to form a shell at a very small size, presumably before it starts feeding by adelphophagy. We have observed this in Mohnia mohni and M. danielsseni. The two species hatch with a shell of three whorls, starting with a protoconch of a diameter of about 0.5 mm. In M. abyssorum we have observed veligers with a shell of 0.6 mm, consisting of slightly less than one whorl. (This species, however, seems not to have nurse eggs, because our preserved capsules are filled with a solid yolk mass.) Also M. abyssorum hatches at a size of three whorls (about 4 mm). When the shells of embryos ready to hatch of these species of Mohnia are compared to those of embryos of Buccinum, the difference is striking (Figs 547, 590). The same applies when apices of the different groups are compared. We assume, however, that the difference does not mean as much systematically as one might believe, but that the development of Buccinum (and other genera with similar larval shell) represents a more advanced type, where the formation of the shell is delayed until shortly before the young leave the shelter of the capsule. Such an evolution, with delay of shell formation may have taken place several times and we do not assume that similar types of larval shell necessarily indicate relationship. Operculum. Opercula of adult buccinids have often been divided into three groups: the Buccinum type with a central or subcentral nucleus, the normal type with an apical nucleus and the Mohnia type with a paucispiral operculum (Figs 442, 413, 431). As in most neogastropod species, the apical portion of the operculum gets eroded with increasing age and it is usually impossible to study the nucleus in adult specimens of Buccinidae. We have examined opercula of both young and adult specimens of almost all species treated in the revision and found opercula of recently hatched young to be much more informative than those of adult specimens. Thus we have been able to distinguish the following types of opercula: NORTH-EAST ATLANTIC NEOGASTROPODA 171 A. Mohnia type (Fig. 431). Paucispirdl. Often this can be seen only in young specimens because the lower part of the operculum is lacking. Occurs in Mohnia. B. Buccinum type (Fig. 442). Concentric growth. Occurs in Buccinum. C. Turrisipho type (Fig. 407). The lower part of the larval operculum is very pointed. The axis of this point forms a small angle with later growth. Occurs in Turrisipho, possibly also in Beringius. D. Colus type (Fig. 413). The operculum of the embryo is regularly ovate and it grows in an open spiral, so the axis of the adult operculum forms a more or less right angle with the length axis of the larval operculum. Occurs in Colus. E. Neptunea type (Fig. 404). Similar to that of Colus, but the growth takes place in the same direction throughout the life of the snail, so the axis of the larval operculum is the same as that of the adult one. Occurs in Neptunea. F. Some other types of opercula, that do not fit into any of these groups, occur in Liomesus, Volutopsius and Kryptos. Radula. The radulae of N Atlantic buccinids have not been used very much for taxonomic purposes, presumably because of the large intraspecific variation reported by Friele (1879) and verified by later authors. We have, however, found the radula to be a useful accessory tool in the classification of the N Atlantic Buccinidae, and give figures of most of them. Two main types can be distinguished: A. Buccinum type (Fig. 469) with a short, broad central tooth with 4-9 cusps with individual bases. Occurs in Buccinum, Neptunea, Volutopsius. B. Mohnia type (Fig. 480) with a more or less square, often thin or reduced central plate with 0-3 cusps with fused bases, often appearing as processes from the anterior edge of the plate. Occurs in Mohnia, Colus, Turrisipho. In addition to these, there are a number of species that have more modified radulae: Belomitra, Liomesus, Kryptos, Troschelia, Beringius . The phylogenetic interpretation of these radulae is discussed under each genus, but our general impression is that they represent groups of low taxonomic level. Among the genera here considered to be buccinids, Belomitra stands out by having a central tooth resembling that of Fasciolariidae. We do not know if this is convergence or indication of relationship: Similarities to Fasciolariidae in the radula are also found in Troschelia. Here, however, it is the lateral teeth that are similar (cf. Figs 484, 486), while the central teeth are of normal Mohnia type. Concluding remarks. The N Atlantic species of Buccinidae may be distributed rather naturally into ten genera, with the exception of Mohnia glypta, M. caelata and M. carolinensis which do not fit very well into any described genus, when radula, operculum and shell shape are used in combination. The two last mentioned of these species show some resemblances to tropical deep¬ water buccinids of the genus Manaria E.A. Smith, 1906, which are very poorly known, the first mentioned species resembles no known buccinid. We have preferred to place these species provisionally in Mohnia until the tropical species are better known. To test our generic concept, we have tried to classify the N Pacific species of which operculum and radula are known, which worked very well. 172 P. BOUCHET & A.

NORTH-EAST ATLANTIC NEOGASTROPODA 185 Genus LIOMESUS Stimpson, 1865 Type species: Buccinum dalei Sowerby, 1825, by monotypy (Fig. 490). Synonym: Buccinopsis Jeffreys, 1867 is an absolute junior synonym. Type species Buccinum dalei Sowerby. (Not Buccinopsis Conrad, 1856). Remarks: There is some doubt about the identity of the type species. We have examined fossil specimens agreeing perfectly with Sowerby’s original description, both from Belgian and British localities and found them to differ from the Recent form by having a larger, more solid shell, blunter and more rounded spire, and coarser striation. Nowhere in the present distribution can populations be found that agree in these respects with the Crag fossil. We have, therefore, preferred to use the specific name ovum Turton, 1825, which is a few months younger than Sowerby’s name and based on the Recent form. The same opinion was expressed by Dali (1916). The genus Liomesus has been separated from Buccinum because of its radula (with a single large lateral cusp and a cusp-less rounded central plate (Sars, 1878)) and an operculum without central or subcentral nucleus. The North Pacific species previously referred to Liomesus have proved to have a more normal buccinid radula and were referred to Pseudoliomesus by Habe & Sato (1973). Liomesus Figs490-491.

Young specimens of L. ovum have a lateral tooth with two large and two smaller cusps and a central plate with several cusps (Fig. 461) and we question if the peculiar radula of L. ovum should not be considered a specific adaptation and the classification of these species should be reconsidered.

Buccinopsis dalei of authors on Recent molluscs, not Sowerby, 1825. Type material: B. ovum , holotype USNM 192257; T. eburneum: holotype ZMO D. 25954. Type locality: B. ovum, off Plymouth, Great Britain; T. eburneum, Vestfjorden, N. Norway, 75-90 m. 75-90 m. Material examined: About 50 shells and specimens from all parts of the distributional area, BMNH, MNHN, ZMO, ZMC, USNM, SMNH. Distribution: From Lofoten (NW Norway) and W and NW of Iceland (Oskarsson, 1966) along the European shelf south to the extreme north of the Bay of Biscay (THALASSA st Z422, 48°21 N, 09°39 W, 1 175 m, 1 fresh shell). Normally it is a shelf species, occurring in 100-300 m but sometimes it is found on the upper part of the continental slope (several records from the Porcupine Expedition 1869 from off Ireland and the Thalassa station above). Remarks: Jeffreys (1867) suspected the type locality given by Turton to be wrong and that it actually came from Co. Cork, Ireland. Fie also figured and described the animal and the egg capsules. M. Sars (1851) described the animal. Except for the synonymy with B. dalei there are no taxonomical problems with L. ovum. It is easily recognized by the almost perfectly smooth, ovate shell of a Buccinum- like shape, but without a central or subcentral nucleus in the operculum. Genus BUCCINUM Linne, 1758 Type species: Buccinum undatum Linne, 1758, subsequent designation De Montfort (1810). Synonyms: Tritonellium Valenciennes, 1858. Type species T. barthae Valenciennes, 1858, by monotypy. Mada Jeffreys, 1867 (not Mulsant, 1850). Type species B. Humphreys ianum Bennett, 1824, by monotypy. Mala Cossmann, 1901 (not Distant, 1854). Replacement name for Mada Jeffreys. Madiella Wenz, 1943. Replacement name for Mada Jeffreys. Remarks: We can see no reason for separating Madiella as a distinct genus. The only character ever given for this is the fine, regular, incised sculpture of B. Humphrey sianum, but this occurs in other species (e.g. B. meridionale Harmer, from Newfoundland), often in combination with a coarser sculpture. NORTH-EAST ATLANTIC NEOGASTROPODA 187 There are some problems with the type designation of Buccinum. Lamarck (1799) cited B. undatum as an example of the genus “pour se faire mieux entendre”, but this can hardly be considered a type designation (R.V. Melville, pers. comm.), although the intention was the same. It will, however, in this case make no difference, because De Montfort designated the same species as Lamarck as type species. The northern species of Buccinum, both of the Atlantic and the Pacific are highly variable and hundreds of different species and forms have been described. We do not intend to make a revision of all these forms, and we have included only the species restricted to deep water, S of the Iceland- Faroe Ridge. N of this ridge, there are some species in bathyal depths, but they normally occur more shallowly and there are no species of Buccinum in the arctic, abyssal fauna (Bouchet & Waren, 1979; Friele & Grieg, 1901). The more southern species of Buccinum are less variable and may be separated by the following characters: A. Axial sculpture dominating B. undatum A. Axial sculpture absent or weak B B. Only a very fine and regular sculpture of equal sized, incised spiral B. humphreysianum lines present B. Spiral sculpture consisting of larger and smaller raised ribs C C. Some spiral ridges with knobs, apertural height greater than spire height B. oblitum C. No spiral ribs with knobs, apertural height less than spire height D D. Two or three sharp spiral keels much larger than the others, animal without eyes B. abyssorum D. Several equal sized, rounded spiral keels present, animal with eyes B. kjennerudae A revision of Buccinum was recently published by Golikov (1980), who recognized about 90 species, but synonymized B. oblitum and kjennerudae with arctic shallow-water species. Buccinum undatum Linne, 1758 Figs 469, 492-493, 590 Buccinum undatum Linne. 1758:740. Type locality: “O. Europaeo”. Type material: Four syntypes in the Linnean Society, London. Distribution: Along the North Atlantic shores, from New Jersey, U.S.A. (Abbott, 1974), north to Greenland (Thorson 1951) (70° N), Spitzbergen (Odhner, 1915), N Norway (Sars, 1878) and S to N Spain (Bay of Biscay, Ortea, 1977), Portugal (Hidalgo, 1917) and possibly the W Mediterranean (Altimira, 1975, Ghisotti, 1974, Jeffreys, 1867, et ai). Normally it occurs in shallow water, 0-100 m, but it has been recorded from bathyal depths (Friele & Grieg, 1901, 1500 m; Sykes 1911, 1450 m, etc.). We have, however, not seen specimens taken alive from depths greater than 500 m (Korsfjorden, W. Norway, coll. AW, cf. Fig. 492). Remarks: B. undatum has been included here only to exclude it from the bathyal fauna. It was not represented by a single shell in the collections made by Travailleur, Talisman, Thalassa, Biacores, Monaco Expeditions, etc., from deep water in the Bay of Biscay, where it is scarce along the S coast. Scattered empty shells occur off Ireland and Scotland (Sykes, 1911) where it is common at the coast and the shelf (Massy, 1930). Therefore we suspect shells to have been carried out by fish, many species of which are known to eat Buccinum. 188 P. BOUCHET & A. WAREN Figs 492-493.

Humphrey sianum: not known. Type locality: B. Humphrey sianum: Cork, Ireland. Material examined: About 150 specimens from all parts of the distribution area, USNM, MNHN, ZMC, SMNH, ZMB, coll. AW. Distribution: Along the European shelf and the uppermost continental slope, from Finmark (N Norway) (Sars, 1878) and E of Iceland (Oskarsson, 1977) to W Morocco (Locard, 1897) and the western part of the Mediterranean (Settepassi, 1977; Casamor & Ghisotti, 1968). The depth distribution is 15 m (Kattegat, ZMC) — 360 m (W Norway, coll. AW) in the northern part and 70 m (Casamor & Ghisotti, 1968) — 1190 m (Locard, 1897) in the southern part of the range. Remarks: The rich synonymy of B. Humphrey sianum is not the result of a high intraspecific variation, but more the result of vain splitting by “la nouvelle ecole” and its recent representatives. We have examined Pleistocene specimens from Sicily (B. striatum Philippi) and found them to fall well inside the variation of Recent B. Humphrey sianum. B. Humphrey sianum has often (the last occasion by Abbott, 1974) been recorded from the W Atlantic and the Arctic, but we have seen no such specimens, despite searching many collections. The egg capsules are hemispherical and are laid singly (Jeffreys, 1867). Buccinum abyssorum Verrill & Smith, 1884 Figs 445, 448, 459, 497-499 Buccinum abyssorum Verrill & Smith in Verrill, 1884:167, pi. 31, fig. 11. Type material: 2 syntypes USNM 35644. Type locality: USFC st. 2111, off North Carolina, 1700 m. Material examined: 24 samples with about 80 specimens from the W Atlantic; INGOLF st 65, 61°33 N, 19°00 W, 2051 m, 2 spms; st 95, 65°14 N, 30°39 W, 1416 m, 2 shs; INCAL CP 05, 55°00 N, 12°30 W, 2884 m, 5 spms; CHALLENGER II, the Rockall Trough, c. 2000 m, several specimens. Distribution: On the lower part of the continental slope, from N Carolina to SW Greenland (Thorson, 1951), SW of Iceland and W of Ireland. Depth range 1400—2900 m. Remarks: There is some degree of variation in the proportions of the shell, but the absence of eyes is a good character distinguishing B. abyssorum from B. kjennerudae. The sculpture is also different in the two species. B. kjennerudae lacks the strong, sharp spiral keels characteristic of B. abyssorum and has evenly rounded ridges instead.

Material examined: The types and 5 shs from the type locality of B. oblitum, USNM and BMNH; 1 sh, off Korsfjorden, W Norway, coll. AW; THOR st 164, S of Iceland, 1900 m, 1 sh; INGOLF st 90, 64°45 N, 29°06 W, 1070 m, 2 shs. Distribution: Only known from the material examined, from the shelf and upper continental slope, from Iceland to S of Portugal. Remarks: B. oblitum can always be recognized by its small size combined with a thickened outer lip, large aperture and spiral ribs with small knobs. The animal is not known, but the shell agrees in all details with that of Buccinum while the sculpture is quite different from the smooth shell of Liomesus. We have therefore preferred to place oblitum in Buccinum, as did Sykes (1911) and Dautzenberg (1925). 190 P. BOUCHET & A. WAREN Buccinum kjennerudae nom. nov. Figs 442, 460, 502-504 Buccinum sulcatum Friele, 1882:32, pi. 3, fig. 18 (not Born, 1778, Meuschen, 1787, Bruguiere, 1792, Sowerby, 1822, Kiener, 1834). Type material: Holotype ZMB 22917. Type locality: Norwegian North Atlantic Expedition st 192, N of Lofoten, 1150 m. Material examined: The holotype and INGOLF st 28, 65° 14 N, 55°42 W, 791 m, 2 spms; st 35, 65° 16 N, 55°05 W, -682 m, 2 shs; TJALFE st 367, 66° 22 N, 57° 16 W, 686 m, 1 spm. Distribution: Only known from the material examined, from N Norway, to Davis Strait, in 600—1100 m. Remarks: The present species has never been recognized as a good species, probably because of its rarity. Golikov (1980) synonymized it with B. polare, a high arctic shallow-water species with distinct axial sculpture. The differences from B. abyssorum are listed under that species. An additional difference is the shape of the spire, which is more convex in B. abyssorum. The name B. sulcatum which was suggested by Friele is preoccupied several times, so we found it appropriate to name it after Miss Johanne Kjennerud, curator at ZMB, who has been of great help in our work.

NORTH-EAST ATLANTIC NEOGASTROPODA 193 Genus TROSCHELIA MOrch, 1876 Type species: Fusus berniciensis King, 1846, by monotypy. Remarks: Boreofusus G.O. Sars, 1878 has the same type species and is an objective junior synonym. Buccinofusus Conrad, 1868 was synonymized with Troschelia by Tryon (1881) and several later authors, but we find that genus more similar to typical species of Fusinus, as did Dali (1909). We do not know any additional species of Troschelia. Troschelia (Thalassoplanes) moerchi Dali, 1908 (figured by Kosuge, 1975) has almost no siphonal canal and quite a different operculum, which is very slender. Fusus perminutus Dali, 1927 from off Florida, resembles the young of Troschelia berniciensis , but was described from immature specimens with no animal, so its systematic position remains uncertain. The radula of Troschelia berniciensis made G.O. Sars (1878) place the genus in Fasciolariidae. Thalassoplanes Dali, 1908 has a similar radula, but the central tooth of Thalassoplanes moerchi (which possibly is a synonym of Brevisiphonia circumreta Lus, 1973) is quite reduced and only a small plate remains. Costaria borealis Golikov, 1977 has lateral teeth with 7 cusps of equal size and a typical buccinid central tooth. Calliloconcha solida Lus, 1978 has the same kind of central tooth as C. borealis but lateral teeth with only three cusps of equal size. We therefore suppose that these groups represent a trend in the Buccinidae, of reduction of the central tooth and a corresponding increase in the number of cusps on the lateral teeth and we prefer to place Troschelia in the Buccinidae.

Type locality: F. berniciensis , deep water off Northumberland (North Sea). Material examined: About 250 shells and specimens from all parts of the distributional area (MNHN, USNM, ZMC, coll. AW). Distribution: Along the NE Atlantic continental shelves and upper slopes, from 56°01 N, 32°42 W, 1200 m (Jeffreys, 1877) (between Iceland and Greenland) to NW Norway (Sars, 1878) and southwards to 25 °N (Locard, 1897). It is not known from the Mediterranean. In Norway it has been found from 90 m (Sars, 1878) down to 600 m on the continental slope (Friele & Grieg, 1901), but occurs deeper (1000 m) in the fjords (AW). Off North-West Africa it occurs in depths between 600 and 2000 m (Locard, 1897). The deepest occurrence is BIACORES stn 252, 47°35 N, 08°47 W, 2700 m, where empty but fresh shells were found. Remarks: T. berniciensis is a rather variable species. Northern specimens are rather broad (Fig. 505), southern specimens more slender (Locard’s N. aquitanica, Fig. 507), and specimens from the deepest part of the distribution are smaller and slender (Watson’s F. amblyterus, Fig. 509). There is also a variation in the number of cusps of the lateral teeth, from 8-10 in northern specimens from shallow water, to about 5 in southern specimens from deep waters (Figs 484-485). Specimens from intermediate localities have intermediate numbers of cusps. 194 P. BOUCHET & A. WAREN Figs 505-510.

Remarks: This genus was placed in Fasciolariidae by Dautzenberg & Fischer (1896), Thiele (1931) and Wenz (1943) while Locard (1897) considered it to belong to Turridae. For reasons given in the introduction to Buccinidae, we prefer to place it in Buccinidae. We do not know of any additional species from the Atlantic which should be classified in Kryptos.

Distribution: The continental slope from the N parts of the Bay of Biscay to S Morocco, 800—2000 m normally. Remarks: K. koehleri is not very variable and no species from the Atlantic can be confused with it except young specimens of Mohnia abyssorum, which resemble the young of K. koehleri. We have not been able to find a precise date of publication of Dautzenberg & Fischer’s (1896) description of K, elegans, but in the same paper (page 434), they refer to Locard (1896), which therefore must be older. The rectum of a specimen soaked for radula preparation was filled with detritus and numerous polychaete bristles. The animal has very small tentacles and lacks eyes. NORTH-EAST ATLANTIC NEOGASTROPODA 197 Genus BERINGIUS Dali, 1887 Type species: Ghrysodomus crebricostaius Dali, 1877, by original designation. Synonyms: Jumaia Friele, 1882:6. Type species Fusus turtoni Bean, 1834, by original designation. Ukko Friele in Norman, 1893:352. New name for Jumaia Friele, 1882. Remarks: The genus is characterized by its short, indistinct siphonal canal, small aperture and the radula with a cuspless central and claw-like, bicuspidate lateral teeth. There is a single N Atlantic and a few N Pacific species. B. crebricostaius is quite similar to B. turtoni in the shell characters, but the sculpture of crebricostaius consists of very strong spiral ribs. Friele’s name was rejected by 1CZN (Opinion 469, 1957) because it was supposed to be blasphemous. Jumaia was a lappish name for the Christian god. At this decision the older and available name Brongus De Gregorio, 1885 was overlooked, but we have selected a type species for Brongus so it becomes a junior synonym of Coins to keep stability in the nomenclature. Beringius brychius (Verrill & Smith, 1885) is here referred to Beiomitra (see that genus). The radula of Beringius was the reason why Habe & Sato (1973) placed the genus in the subfamily Liomesusinae (sic!). Japelion Dali, 1916 and the questionable genus Noeberingius Habe & Ito, 1965 have a. radula very similar to Beringius and are probably closely related, as the shells also indicate. Liomesus on the contrary has quite a different shell, and the similarities in the radula are caused by enlargement of the base of a normal bu canid lateral tooth in Beringius while in Liomesus there is reduction of the inner cusps of the same tooth. When drawings of the teeth are compared, this difference is not evident, but in SEM pictures it is.

Distribution: From 80° N, between Spitzbergen and Greenland and N of Franz Joseph’s Land (Friele, 1882, Gorbunov, 1946), on the continental shelves southwards to NE Norway (Verkruzen, 1875), along the Norwegian coast (Sars, 1878), the North Sea (numerous records), Shetland (numerous records), the Faroes (unpublished in ZMC), Iceland (Thor son, 1941; Oskarsson, 1962), E, S, W Greenland (Thorson, 1944; Clarke, 1974; unpublished in ZMC), Arctic Canada from 95° W (McPherson, 1971), S to 150 miles S of Cape Race, Newfoundland (unpublished, in USNM). In Greenland it is known from 25 m, in other places the normal upper limit is about 100 m and it is known down to 1447 m (Golikov, 1964) although the lower limit usually is 600 m. Remarks: Several attempts have been made to distinguish two species, B. turtoni and B. ossiania (Friele, 1882; McPherson, 1971; Thorson, 1935). We have examined the types of B. ossiania and the differences from the typical form in the North Sea were noticed, but most specimens we have seen are intermediate and there is no difference in the distribution of the forms, so the names should not even be used for subspecific separation. 198 P.

The differences in the egg capsules mentioned by Friele (1882) are probably the result of variation because his description of the egg capsules of B. ossiania agrees very well with Jeffreys’ description (1867) which was based on typical B. turtoni. Jeffreys described the colour of the capsules as “pale orange’’, Friele (1882) said that the capsules of B. ossiania were “citron-yellow’’ while Thorson (1935) said that the capsules of B. turtoni were more yellow than those of B. ossiania. Howse (1847) figured in the capsules and described them as “pale yellow’’. NORTH-EAST ATLANTIC NEOGASTROPODA 199 Figs 517-519.

Type species Strombus norwegicus Gmelin, 1790 by monotypy. Remarks: The genus Volutopsius contains a few arctic species. Tiba & Kosuge (1979) listed the N Pacific species. In the N Atlantic there are two species, V. norwegicus and V. (Pyrulojusus) deformis (Reeve, 1847). V. deformis is sinistral and has lateral teeth of normal Buccinum type. V. harpa (Morch, 1857) has often been considered a subspecies of deformis, but has the same kind of lateral teeth as norwegicus (Habe & Sato 1973) and should be kept distinct. The variation in the lateral teeth in this otherwise uniform group of species clearly shows that it is of little or not value above the specific level.

Type locality: S. norwegicus, Norway; F. largillierti, Newfoundland. Material examined: About 150 shells and specimens from all parts of the range. Distribution: From Spitzbergen, E and W Greenland southwards on the continental shelves, to the North Sea, Shetland, The Faroes, and Iceland (Odhner, 1915; Thorson, 1944; Schlesh, 1926; Sars, 1878; Jeffreys, 1867), and from Arctic Canada, c. 95° W, to George’s Bank, 42° N (Macpherson, 1971 and unpublished material in USNM). It is restricted to the continental shelf, 25 m (E Greenland, Thorson, 1941) to about 600 m (numerous records) except S of Iceland where it occurs down to 2000 m (unpublished material in ZMC). Remarks: There is a distinct cline in the size of the larval shell in V. norwegicus, W Atlantic specimens having a larger one, but examination of a large collection in ZMC from Iceland and Greenland proved that it is hardly possible to separate V. largillierti more than possibly as a western subspecies, not sharply limited from the nominal species. Examination of further Siberian material may show that V. middendorffi (Dali, 1891) belongs to the present species and it thus has a more or less circumpolar distribution.

Type species Fusus spitzbergensis Reeve, 1855. Remarks: Aulacofusus spitzbergensis is quite similar to Neptunea antiqua, in shell, radula and opercular characters and differs mainly by its smaller size. We can therefore see no reason for separating Aulacofusus, even as a subgenus. It is not our intention to discuss the despecta - antiqua complex or the numerous arctic forms, but we have limited our discussion to the two species that occur on the upper parts of the continental slope in Europe and N. brevicauda which has a similar distribution in the NW Atlantic.

Neptunea terebralis Gould, 1860:326 (not Lamarck, 1803). Fusus lividus Morch, 1862:36. Type material: F. brevicauda, holotype in MNHN; F. spitzbergensis, holotype BMNH 197654. Type localities: F. brevicauda, not known; F. spitzbergenis , said to come from Spitzbergen. Material examined: 20 samples with about 40 shells and specimens, all from the NW Atlantic. Distribution: From Maine and northwards along the N American Arctic coast, to the state of Washington in 2 — 548 m (Macpherson, 1971), Bering Sea and the Sea of Okhotsk (Middendorff, 1849). Not known from the Siberian coast, the NE Atlantic or Greenland. Remarks: Fusus spitzbergensis was said to originate from Spitzbergen in the original description, but no later writers on molluscs from Spitzbergen have reported it, nor is it present in any collections we have examined from the NE Atlantic. Pain (1978) figured a specimen from “west of Spitzbergen, 400 m”, but his figure shows a specimen of Colus sabini. Therefore we suppose the species to be absent from the N Atlantic, except the American coast. We.have therefore preferred to use the older name of Deshayes, which does not imply an erroneous distribution. No locality was given for Fusus brevicauda, but on the label one can read “Kamchatka” (NW Pacific), which probably has been added later. Probably some specific names described in various papers by Dali have to be added to the synonymy. N. brevicauda looks like a slender, miniature N. antiqua, but has more regular sculpture. Neptunea antiqua (Linne, 1758) Figs 405, 476, 525-526 Murex antiquus Linne, 1758:754 Type locality: “In oras Europaeo”. Type material: Two syntypes in the Linnean Society, London.

AW, USNM, ZMC, SMNH). NORTH-EAST ATLANTIC NEOGASTROPODA 203 Distribution: Uncertain to the north and west. It is common in S Scandinavia and around the British Isles, 15-1000 m (Seaward, 1982; Pearce & Thorson, 1967). Remarks : In our material from deep water, there are a few empty shells from the Bay of Biscay and a single one from off N Portugal, which agree well with the form common off the British Isles and Scandinavia in deep water. They are all old and rather worn and probably fossil. This form can neither be attributed to typical N. antiqua which is the form common in shallow water in the Skagerrak, the Kattegat and the southern Baltic, nor can it be identified with typical N. despecta , which is a more heavily sculptured northern form. Intermediates between all these forms occur, but each of these populations can be recognized from the shell with certainty. The relations between these populations are not known. Locard ( 1 886) published several records from the Channel and the Bay of Biscay, in shallow water. We have not seen any specimens in his collection, which now is in MNHN, and doubt the validity. ■ The biology of N. antiqua is fairly well known. Pearce & Thorson (1967) summarized what is known, and Fange (I960) reported on its poisonous salivary secretion. Neptunea contraria (Linne, 1771) Fig. 527 Murex contrarius Linne, 1771:551.

Distribution: Along the shelf and upper continental slope from the southern parts of the Bay of Biscay to Morocco (Locard, 1897) in 100—1000 m. Mediterranean records seem to be based on fossil specimens (Barsotti & Frill i, 1970). Remarks: There have been numerous discussions in the literature whether M. contrarius was based on the normally sinistral S European species or on a sinistral specimen of N, antiqua. Examination of the holotype proved that the name was based on the S European species, as Hanley (1855) concluded. Dautzenberg (1910) recorded N. contraria from Cap Blanc, Mauretania, without any comments about the depth. We have examined this specimen in IRSN, and although the shell looks very fresh, the label says that it was collected at 32 m above sea level in a quaternary deposit. Neptunea contraria resembles sinistral specimens of N. antiqua , which occasionally occur, but can be separated by having a sculpture of coarser but more equal sized spiral ribs, that are rounded, never sharp. Some details on the anatomy of N . contraria were given by Fischer & Bouvier (1890). Golikov (1963) regarded N. contraria as a subspecies of N. antiqua but we cannot agree. The fossil history of N. contraria goes back to the Pliocene, as does that of N. antiqua , and there has never been any mixing of them (cf. Harmer, 1914 and Strauch, 1972). 204 P. BOUCHET & A.

NORTH-EAST ATLANTIC NEOGASTROPODA 205 Genus MOHNIA Friele in Kobelt, 1878 Type species: Fusus mohni Friele, 1877, by monotypy. Remarks: In Mohnia we have included a number of bathyal and abyssal buccinids that have a more or less distinctly spirally-coiled operculum and a small initial whorl in the larval shell that increases its diameter regularly (Figs 534, 537, 540, 543). The radula has a more or less square central tooth with one or three cusps and lateral teeth with two major and 0-2 minor cusps between these. All species we know of Mohnia are true deep-water species. They are known from the N Atlantic, the N Pacific, and the Arctic basins. In some species the spiral coiling of the operculum can be observed only in young specimens because its older parts get worn rather early in life. We have divided Mohnia in two subgenera, Mohnia s.str. and Tacita. The species of Tacita have a more or less distinct axial sculpture in addition to spiral lines and lose the spirally-coiled part of the operculum early in life. The species of Mohnia laek axial sculpture and usually the operculum keeps the apical part throughout life. In Mohnia we have also included some species for which we could not find a better genus, although we are not satisfied with their position here, viz. M. carolinensis, M. caelatus and M. glyptus. The species referred to Mohnia can be determined by the following key: A. Only spiral sculpture present, suture not very deep B (Mohnia s.str.7 A. Axial sculpture usually present D B. Three or four major spiral ribs on the upper whorls M. mohni B. Several to many spiral ribs or lines present C C. Spiral ribs of unequal size, separated by broader interstices M. parvus C. Numerous fine spiral ribs of equal size, separated by narrow interstices M. simplex D. Whorls with a distinct shoulder M. (T.) blakei D. Whorls evenly rounded E E. Broad, rounded axial ribs present on all whorls F E. Axial sculpture usually present only on the upper whorls H F. Spiral sculpture forms knobs at the intersections with the axial ribs M. carolinensis F. Spiral sculpture disappears on the axial ribs G G. Columella distinctly curved M. caelatus G. Columella almost straight M. glyptus H. Axial sculpture of strong short ribs on the upper whorls M. (T.) abyssorum H. Axial sculpture of rather indistinct, broad growth lines I I. Spiral lines sharp M (T.) krampi I. Spiral lines low and rounded M (T.) danielsseni Mohnia (Mohnia) mohni (Friele, 1877) Figs 435,482,530-531 Fusus mohni Friele, 1877:6.

WAREN Material examined: 3000 shs and spms, listed by Bouchet & Waren (1979) and from INGOLF st 104, 105, 107, 110, 111, 112, 113, 116, 117, 118, 119, 120, 124, 125 and 139, W and NW of Iceland, 650-2300 m; 81° 14 N, 22°50 E, 150 m, 1 sh, SMNH. Distribution: The Norwegian and Arctic abyssal basins (Bouchet & Waren, 1979; Lus, 1981), in 650-3800 m. Remarks: M. mohni is only likely to get confused with M. danielsseni, with which it occurs together, but it can easily be separated by having the apical whorls of half the diameter of M. danielsseni (Figs 531, 540). Some details on the reproduction were given by Bouchet & Waren (1979). It can be added that the capsules are not attached to some firm substratum as are those of M. danielsseni. The specific names Mohnia alba and Fusus tener which have been mentioned in the literature, are manuscript names of Friele and Jeffreys. Kobelt (1878) used the name Mohnia alba on plate 9 (fig. 5), but in the text he said that this name should not be used.

Distribution: NE America from 39° N, to SW Iceland and NE Greenland, 200 — 2000 m. Remarks: This species is characterized by its uneven sculpture, which in worn specimens has an additional incised line on each spiral rib. The specimens from NE Greenland were determined dalli by Posselt (1895) and formed the base for the only record from Greenland. Thus dalli can be cancelled from the list of gastropods from Greenland.

Material examined: The holotype and USFC st 2470, 44°47 N, 56°34 W, 440 m, 1 spm; USFC st 54B, 42°49 N, 68°48 W, 200 m, 2 shs; Lindenows Fjord, SE Greenland, 400—600 m, 1 sh, ZMC; INGOLF st 35, 65° 16 N, 55°05 W, 682 m, 5 spms. Distribution: On the upper continental slope, from N Carolina to S Greenland, only known from the material examined. Remarks: The opercula from the specimens from USFC st 2470 and INGOLF st 35 show only traces of being paucispiral. Verrill described it as “distinctly but less than M. mohni paucispiral”. No original material with soft parts was available to check this, but a specimen in the Locard collection, without precise locality data, had a more distinctly coiled operculum, corresponding to the description. This may indicate that more than one species is involved, but we find it more likely that it depends on intraspecific variation. One of the specimens from the INGOLF expedition had a large parasitic copepod in the oviduct. NORTH-EAST ATLANTIC NEOGASTROPODA 207 Figs 530-534.

BOUCHET & A. WAREN Subgenus TACITA Lus, 1971 Type species: T. holoserica Lus, 1971, by original designation. Remarks: The type species was described from the Kuril Trench, in 6100 m. Its anatomy was described in the original description. The shell, operculum and radula resemble rather closely those of M. abyssorum and M. danielsseni. Lus introduced the genus after comparison with Neptunea and Sipho and did not give any distinctive characters in relation to Mohnia. From shell morphology, radular characters and operculum we find this genus very close to Mohnia, but keep it as a subgenus for a number of species that have a less distinctly spirally-coiled operculum, usually are of a larger size and often have some axial sculpture.

Distribution: The abyssal parts of the Norwegian and Arctic Basins 1400-3700 m. Remarks: Some information about the biology was given by Bouchet & Waren (1979). For differences from M. mohni, see that species. M. krampi resembles M. danielsseni, but has sharper spiral ridges, flatter whorls and a more narrow aperture. Lus (1981) placed M. danielsseni in Colicryptus, which she regarded as a subgenus of Coins . Colicryptus is here considered a synonym of Turrisipho and is characterized by an apical, pointed nucleus of the operculum (Fig. 407). Therefore we prefer to keep danielsseni in Mohnia.

Remarks: This is one of the most characteristic species of the upper abyssal area of the N Atlantic. It is represented by numerous samples from 2500 m— 4800 m but only four more shallow and a single below 4850 m. The S distribution is uncertain because of lack of sampling stations, but it is not present in material from the Verna fracture zone, about 11° N, 5100-5900 m. Young specimens of M. abyssorum resemble M. blakei slightly but M. blakei has more narrow axial ribs and a larger larval shell. Young specimens also resemble Kryptos koehleri of the same size but are broader and increase their diameter more rapidly (Figs 513, 542). Several egg capsules were present in our material. The capsule is ovate, 5 mm long and about 3 mm in diameter. It is attached to the substratum by a stalk, Y-shaped in cross section and 1.5 mm high, originating centrally from the longer side of the capsule. The capsule is filled by a homogeneous yolk. In two capsules there was a very young embryo in the veliger stage, in a third capsule (Fig. 546) solid yolk; in two capsules there were young almost ready to hatch. Figs 546-547.

WAREN Mohnia (Tacita) krampi (Thorson, 1951) Figs 425, 449, 538 Sipho krampi Thorson, 1951: 54, fig. 16. Type material: Holotype and 7 paratypes in ZMC. Type locality: 69°50 N, 61°36 W, 1880 m, Baffin Bay. Material examined: The type material. Distribution: Clarke (1974) recorded A/, krampi from 570-2300 m, (4 stations) in Baffin Bay. It has not been taken outside the deep parts of Baffin Bay. Remarks: This species resembles M. danielsseni rather closely but is more slender and its whorls are higher. All material we have examined is badly corroded and the larval shell is not known. Mohnia carolinensis (Verrill, 1884) Figs 434, 457, 555-556 Urosalpinx carolinensis Verrill, 1884:237.

Material examined: The material examined by Verrill (1884). Distribution: Only known from off North Carolina, 250-1700 m. Remarks: A7. carolinensis was described as as muricid, but was referred to Mohnia by Radwin (1972), who examined the radula. We have examined the operculum of a young specimen, 4 mm high, and it is slightly paucispiral. The shell, however, differs widely from Mohnia , in being solid with strong axial sculpture and it will probably prove to be more closely related to certain tropical buccinids from deep water that now are considered to be fusinids. The only species that M. carolinensis can be confused with is M. caelatus, which differs from M. carolinensis in having a weaker spiral sculpture, where the spiral lines disappear on the axial ribs.

Distribution: along the upper part of the continental slope, from North Carolina to S of Iceland, 1000-2500 m. Remarks: Comparison of the rich material of the species proved that all intermediate forms exist, although there is a tendency to form uniform populations. The name obesus was based on a juvenile specimen, var. hebes on an unusually broad specimen. For differences from M. carolinensis, see under that species. The operculum is slightly paucispiral. M. caelata is quite similar to M. frielei (Dali, 1891)andM. robusta ( Dali, 1913) from deep water in the N Pacific.

Distribution: From off New Jersey, along the upper continental slope, northwards to S of Iceland, c. 300-1000 m. Only known from the material examined. Remarks: The shell of M. glyptus does not resemble Mohnia, especially in the characters of the larval shell, but we have not found any genus that resembles this species and we have not wanted to describe a new genus for it. The shell of M. glyptus resembles that of Metzgeria, but species of Metzgeria have distinct columellar folds. The larval shell of M. glyptus is remarkable (Fig. 554) because of its irregular shape and it does not resemble that of any buccinid known to us. It is, however, a good character for recognizing this species. 214 P. BOUCHET & A. WAREN Figs 548-554.

NORTH-EAST ATLANTIC NEOGASTROPODA 215 Genus TURRISIPHO Dautzenberg & Fischer, 1912 Type species : Fusus lachesis Morch, 1869, by original designation. Synonyms: Colicryptus Iredale, 1918. Type species Fusus fenestratus Turton, 1834, by original designation. Undacolus Nordsieck, 1968. Type species Neptunea undulata Friele, 1882, by original designation. Remarks: The species of Turrisipho are characterized by having the nucleus of the operculum drawn out into a small apical point, a squarish central tooth of the radula with 1-3 cusps, a distinct, hairy periostracum and a high slender shell with numerous whorls. The species here included in Turrisipho have previously been placed in a number of different genera, and Lus (1981) referred Mohnia danielsseni to Colicryptus. We find, however, the group here put together to be a very uniform group, especially when young specimens are compared. The pointed apical part of the operculum is especially characteristic and we have not seen anything similar in other buccinids. The species of Turrisipho can be separated by the following key: A. Aperture constitutes 0.4 of the total height of the shell or less B A. Aperture constitutes more than 0.4 of the total height C B. Diameter of third whorl c. 4 mm T. voeringi B. Diameter of third whorl c. 2.5 mm T. lachesis C. Siphonal canal well developed, occupying 1/3 of the height of the aperture T. dalli C. Siphonal canal short and broad D D.

No axial ribs j. moebii Turrisipho dalli (Friele, 1881) Figs. 557-558 Sipho dalli Friele in Tryon, 1881:133 (Not Fusus ( Neptunea ) dalli Watson, 1882:379, renamed Fusus (Sipho) liberatus Watson, 1886:206). Type material: Holotype, ZMB 20644. Type locality: Between Bear Island and Norway, 350 m. Material examined: PORCUPINE 1869, 61 °21 N,03°44W, 1160 m, 1 sh; MONACO st 922, 58° 16 N, 05°48 W, 343 m, 1 spm; Varangerfjord, N Norway (G.O. Sars leg., ZMO), 1 sh; off Korsfjorden, W Norway, 250-325 m, 1 spm, 10 shs, coll. A.W.; the material listed by Friele (1882). Distribution: From Barents Sea, along the Scandinavian shelves, S to the Shetland — Faroe Channel and E of Iceland (Oskarsson, 1977). Remarks: Live specimens of T. dalli are easily recognized by the greyish shell with rows of periostracal bristles along the spiral keels. When dead, it is well characterized by the rounded, slightly-shouldered whorls, polygyrate larval shell, its slender siphonal canal and the rather sharp axial sculpture of incremental lines and alternating spiral keels and smaller ribs. On the shoulder, the spiral ribs are of equal strength. T. dalli was recorded from NE Greenland by Posselt (1895), but examination of the material proved that the record was based on Mohnia parva, and the species thus is unknown from Greenland. We have not seen opercula of very young specimens, but shells of young specimens are very similar to those of other species of Turrisipho.

Distribution: N and W of Norway, 200-1100 m (Frieie, 1882, as lachesis, typical form and undulata), E and NW of the Faroes (Sykes, 1911 and ZMC) 500-900 m, N and NW of Iceland 200-1500 m (Thorson, 1941 and ZMC), SE Greenland, 400-600 m(Thorson, 1944 as lachesis smooth variety), SW Greenland and Davis Strait, 600-1100 m (Thorson, 1940 as undulatus, INGOLF & TJALFE, ZMC) and off Newfoundland, 1267 m (Dautzenberg & Fischer, 1912 as undulatus ). Remarks: Morch’s original description of lachesis was based on a very poor specimen (Fig. 565) and this led to much confusion. Frieie (1882) and G.O. Sars (1878) interpreted it correctly, but after Frieie’ s description and illustration of var. bicarinata (see voeringi) later authors used the name lachesis for the “variety”. Thorson (1940) described the egg capsules and larval development of what he considered to be Sipho undulatus but we doubt his identification. To give an impression of a higher certainty in his identification of the capsules on which his description was based, he mentioned that S. undulatus was taken at two adjacent INGOLF stations, nos 25 and 28, but he did not mention that they originated from depths of 1096 and 791 m, while the egg capsules came from 2260 m, 700 m deeper than any of the about 20 records we know of. There is also a difference in the sculpture of his drawing of the larva and actual specimens of T. lachesis. His drawing does not show the faint, but distinct shoulder of the body whorl of the larva which is well shown in his drawing of the apical whorls of an adult specimen. We have not been able to find his specimens in ZMC and are not able to say on which species his description was based. Some specimens of T. voeringi resemble lachesis considerably, but can always be separated by their proportionally shorter siphonal canal, more convex whorls of more slowly increasing diameter, and the diameter of the third whorl is about 4 mm in T. voeringi , while it is 2.5 mm in lachesis. T. fenestratus can be separated by its broader and more solid shell of a larger apical angle and shorter siphonal canal. T. dalli has a much stronger spiral sculpture and T. moebii has more rapidly growing diameter of the apical whorls and a much broader shape. Turrisipho voeringi nom.nov.

Remarks: The present species was well described and figured by Frieie (1882) under the name lachesis var. bicarinata , a name that cannot be kept because of Kobelt’s earlier use of it. Later authors have used the name lachesis in that sense. We consider lachesis and var. bicarinata two NORTH-EAST ATLANTIC NEOGASTROPODA 217 distinct species, because we have never seen any transitional specimens and the two forms can always be separated by the characters mentioned under lachesis ; it therefore has to be given a new name; Turrisipho fenestratus (Turton, 1834) Figs 406, 483, 571-574, 591 Buccinum fusiforme Broderip, 1830:45 (not Borson, 1822).

Material examined: The types and about 100 specimens from all parts of the distribution area. Distribution: From Angmagsalik (SE Greenland), SW and S of Iceland (Thorson, 1944, 1941; Clarke, 1974; material in ZMC), to Lofoten (N Norway) and southwards to W Norway (G.O.

It does not occur in the Mediterranean. The depth range is from 50 m in the N and 400 m in the S, down to 1200 m. Remarks: T. fenestratus is well characterized by its solid shell and short siphonal canal. For differences from T. lachesis, see that species. Two specimens from the Faroes (432m, in ZMC) have been found in stomachs of Anarrhichas latrifrons (Pisces). A single egg capsule of T. fenestratus was found 26 Jan 1971 in the S part of Hjeltfjord, W Norway in 90-120 m. It has a diameter of 5.5 mm, a tough, rather thick, leathery wall, it is yellowish brown and spherical with a well-defined attachment area covered with sand grains. It contained a single embryo of 3 whorls and several groups of cells, that evidently were used as nourishment. Turrisipho moebii (Dunker & Metzger, 1874) Figs 407-408, 455, 575-578 ?

Type locality: F. moebii, between Lindesnes and Listerfjord, S Norway, 195 m. Material examined: About 40 shells and specimens from all parts of the distribution area. Distribution: From between Bear Island and Norway, to NE Norway and along the Norwegian coast into the Skagerrak (Friele, 1882; G.O. Sars, 1878; material in ZMC) and from about 27° W, off Iceland, along S Iceland (Thorson, 1941; material in ZMC), the Faroes (material in ZMC and Sykes, 1911) and off Ireland (Massy, 1930). The depth range is 200 — 957 m. Remarks: The nomenclatorial history of the present species is very confused. The main source of this confusion was Morch’s description of Fusus ebur from W Greenland (= sabini Gray). That species often has quite convex whorls and other malacologists did not recognize it from the description but believed the description to be based on T. moebii. This mistake can also be partly blamed on the poor condition of Morch’s specimen. The manuscript name of Jeffreys (sarsi) that was validated by G.O. Sars (1878) has been in common use, but is preoccupied by Wood’s use of the name for a British Pleistocene fossil (secondary homonym). One of the specimens from the Faroes (in ZMC), from 400 m, had been taken from the stomach of Anarrhichas lupus (Pisces). T. moebii can be recognized from its convex whorls, deep suture, hairy periostracum (greenish brown in fresh specimens), regular sculpture and multispiral larval shell. 218 P. BOUCHET & A.

Type species by original designation Waipaoa munida Ponder, 1962. Remarks: Belomitra has always been considered a turrid genus (Powell, 1966), although Vayssiere (1930) showed that it has a buccinid radula (Figs 488-489). The radula of Morrisonella is known and agrees well with our figures. Dellina is known only from empty shells, and was considered to belong to Cancellariidae, but we find the shell so similar to Belomitra that we have synonymized it. Our material of B. quadruplex shows great variation and there exist several areas where the species occurs in more shallow water and forms morphologically separable populations. There is, however, a continuous transition to the more uniform deep-water form. Such shallow-water populations exist in the Bay of Biscay and the Azores. These shallow-water animals lack eyes, like the deep-water form; we therefore find it more likely that they are shallow-water outcrops of a deep-water species, than the opposite, because it is most unusual for shallow-water neogastropods to have no eyes, while many deep-water species do lack them. Belomitra richardi (Dautzenberg & Fischer, 1906) is known only from a few specimens and we have not been able to decide whether it is a valid species or only another shallow-water offshoot of B. quadruplex. The species of Belomitra resemble mitrids, but lack columellar folds and are easily distinguished by the radula. The genus is characterized by the distinctly shouldered whorls and the peculiarly shaped lateral teeth. The central tooth of Belomitra resembles that of Fasciolariidae more than that of Buccinidae, but the lateral teeth are more like those of Buccinidae. We have preferred to place Belomitra in Buccinidae simply because there is more variation in the buccinid radula than in the fasciolariid one, as far as one can judge from the literature.

Distribution: The lower parts of the European continental slopes, from S of Iceland, south to 19° N. In the Azores and the Bay of Biscay it also occurs more shallowly, up to about 300 m. It also occurs all over the N Atlantic abyssal area, but does not reach the N American continental slope. The deepest records are from about 5300 m (Fechter, 1979). Remarks: The animal lacks eyes and has direct development. The variability is discussed under the introduction to the genus. Abyssal specimens tend to be larger and have a thinner shell (“brychia” Verrill), bathyal specimens are more solid and smaller ( “ paradoxa ’ ’ Fischer).

Remarks: The history of the name Sipho, which has been much used for the species here placed in Colus, needs to be discussed because the name Sipho has been used until recently and the case has never been thoroughly treated. Klein (1753) used the name for a number of slender neogastropods and this was repeated by Bruguiere (1792:532). This use by Bruguiere (1792) does not validate the name, because Bruguiere only repeated the classification used by Klein, to give the nomenclatorial history of these gastropods, and he did not use the name himself. Fabricius (1823:83) is cited by Sherborn, and Fabricius (dated 1822) is also cited by Herrmannsen as the first validation of Sipho. Fabricius’s work is a list of his collection and no descriptions are given. He cited four names under Sipho viz. infundibulum, turritus, polygonus and striatus. These names are nomina nuda and the work has been rejected by ICZN (Opinion 521). Therefore the name cannot be ascribed to Fabricius. The next time Sipho was used was by Brown (1833), who described Sipho striatus. This is a junior synonym of Puncturella noachina (Linne, 1758). No other species were mentioned in Sipho by Brown, and therefore Sipho becomes a junior synonym of Puncturella Lowe, 1827. We have therefore followed Dali (1906, 1918), Iredale (1915) and Winckworth (1932) in their use of the name Colus, with Murex islandicus as type species. They had, however, overlooked the validation of this name by Mohr (1786), and ascribed the name to Gmelin (1790). This does not change anything, because these two authors both refer to Chemnitz’s non-binominal use of the name. We have used Colus for a rather heterogeneous assortment of more or less slender buccinids with an operculum with apical nucleus, a radula with a mono- or tricuspidate, square central tooth and laterals with 2 major and 0-3 smaller cusps. There are several names available for a subgeneric division of Colus. The following names are based on N Atlantic species: Siphonorbis Morch, 1869. Type species Fusus (Siphonorbis) ebur Morch, 1869, subsequent designation by Cossmann (1901). (Friele’s (1882) designation is not valid because the species designated as type was not originally included in Siphonorbis.) Siphonellona Wenz, 1941 . New name for Neptunella Verrill, 1873 (not Meek, 1864) and Siphonella Verrill, 1879 (not Macquart, 1835). Type species Fusus pygmaeus Gould, 1841, by original designation. Plicijusus Dali, 1902. Type species Fusus kroeyeri Moller, 1842 by original designation. Synonym: Parasipho Dautzenberg & Fischer, 1912, with the same type species. Anomalosipho Dautzenberg & Fischer, 1912. Type species Sipho verkruezeni Kobelt, 1876, by original designation. None of these names, however, has a type species that is a member of any significantly different group of species, except perhaps Siphonorbis. Colus sabini ( = ebur), the type of Siphonorbis, has a perfectly smooth larval shell of about three whorls, almost identical to that of C. holboelli and C. terraenovae. We are not able to take any decision about this until the N Pacific species of the group are better known and prefer to leave the N Atlantic Colus species without a subgeneric classification. NORTH-EAST ATLANTIC NEOGASTROPODA 227 In addition to the species treated here, we have seen two forms from the N American east coast, that we were unable to classify (Figs 644-646). They may prove to be forms of C. pygmaeus, but more material from other localities is needed to show this. Because of the great variation of several of the species, it is close to impossible to give a key to the species, but this attempt may give some help in their determination. A. A. B. B. C. C. D. D.

WAREN Material examined: More than 1000 specimens from all parts of the distributional area, MNHN, USNM, ZMC, SMNH, coll. AW, ZMB. Distribution: From the Murmansk area (Middendorff, 1849; Herzenstein, 1885) and southwards along the Scandinavian coasts, to S Kattegat (Thorson, 1946), the British Isles (Seaward, 1982), the Bay of Biscay and south to N Portugal (several THALASSA stations). It occurs in the Faroes (Sparck & Thorson, 1933), S, W and N Iceland (Thorson, 1941) and SE Greenland (Thorson, 1944 as turgidula var. minor and unpublished material in ZMC). C. gracilis lives on the continental shelf and the upper slope in 50 — 1500 m. Remarks: C. gracilis is a highly variable species that occurs in several morphologically different geographical and bathymetrical forms. These forms may look identical over large areas and easily give an impression that several species are involved. For Norwegian specimens the name glaber has been used. This is a smooth form with flatter whorls and proportionally greater breadth than typical gracilis. The glaber form reaches the Faroes, Shetland and Iceland. In the Faroes and Shetland there is a transition to typical gracilis , while in Iceland there is a tendency to get still smoother, broader and with flatter whorls, which misled Thorson (1944) to refer specimens to C. turgidulus (Fig. 598). The transition to typical gracilis can also be seen in the North Sea, where the specimens are quite intermediate. To the W and NW of the British Isles and along the Iceland - Faroe Ridge the glaber form enters deeper water and at the same time the periostracum becomes less distinct, the shell smoother and the siphonal canal more curved (Fig. 599). To the south, in shallow water, there is little variation in the gracilis form, although there exist local populations with a more solid shell and convex whorls, from which Locard described nicolloni (Fig. 596). In deeper water there is an increase in size, a reduction of the thickness of the shell and an increase in the convexity of the whorls, from the Faroe-Rockall area southwards. The typical form from the Bay of Biscay in 700 — 1300 m looks very distinct from the shallow-water form of the same area (Figs 600, 603). These three different forms, gracilis (Fig. 597), glaber (Fig. 594) and the S deep-water form (Fig. 600) may possibly be worth subspecific distinction. The egg capsules were described by Jeffreys (1867) but have never been figured so we give figures of specimens from W Norway and deep water in the Bay of Biscay, to show the differences between the populations and to emphasize that differences in the egg capsules should not be used uncritically to prove specific separation. C. gracilis has been reported from the Mediterranean several times (Crosse, 1875; Spada & Maldonado, 1974, e.g.) but these records have been based on C. jeffreysianus.

Type localities: F. holboelli, W Greenland; F. tortuosus, N of Beechey Island, NE Canada. Material examined: About 300 shells and specimens from all parts of the distribution area, ZMC, SMNH, USNM, MNHN, BMNH. Distribution: Arctic Canada from 90° W (Macpherson, 1971 as tortuosus), W Greenland (Thorson, 1951 as turritus), E Greenland (Thorson, 1944 as tortuosus ), W, N and E coasts of Iceland (Thorson, 1941 as tortuosus), between Shetland and the Faroes (Jeffreys, 1883, as delicatus), deep water off Norway and the Norwegian coast to Spitzbergen (Sars, 1878; Friele, 1882). We have seen no material from Spitzbergen. Normally it occurs in 400-1500 m, although it occurs more shallowly in Greenland and Iceland, 10-500 m. NORTH-EAST ATLANTIC NEOGASTROPODA 229 Remarks: As was pointed out by Friele (1882), Jeffreys and G.O. Sars were using the name attenuata in different ways. Jeffreys used it for a deep-water form of C. jeffreysianus. The specific name holboelli could possibly be considered a nomen oblitum, but we have preferred to use it because of the confusion in the use of tortuosus. We have selected a specimen of C. holboelli in the collection of H. Cuming, BMNH, from “Arctic Seas” as neotype of C. tortuosus , to stabilize the nomenclature. Harmer (1914) described Sipho exiguus from the British Crag formation and mentioned that he had seen specimens in SMNH from Iceland. We cannot judge the validity of the fossil species, but suppose the Recent record to be based on C. holboelli of which certain Icelandic specimens resemble Harmer’s figures closely. C. holboelli is a rather variable species. The type and other specimens from W Greenland are almost as solid as C. gracilis while specimens from deep water have a thin, fragile shell. Norwegian specimens are smaller and more slender. C. holboelli resembles C. sab ini, but has a smooth periostracum, a more curved siphonal canal and the outer lip is not evenly arched where it goes over into the siphonal canal as in C. sabini. Very young specimens may resemble C. terraenovae in having a similar shape and larval shell, but that species has a proportionally higher aperture. When the larval shell is too corroded to be examined C. holboelli can be distinguished from other species by its more slender and twisted siphonal canal.

Type material: F. islandicus, lectotype, here selected, in ZMC (Fig. 612). Type locality: F. islandicus, Iceland. Material examined: About 200 specimens from all parts of the distributional area. Distribution: Along the shelf and upper part of the continental slope from aVctic Canada (90° W, Macpherson, 1971), to 150 miles S of Cape Race, Newfoundland (unpublished, USNM), W and E Greenland (Thorson, 1944, 1951), Iceland (Thorson, 1941), the Faroes (Sparck & Thorson, 1933), Spitzbergen (Odhner, 1915), Norway (G.O. Sars, 1878), the outer parts of the Skagerrak and the North Sea (unpublished material in ZMC), Shetland and W of the British Isles (Seaward, 1982; Massy, 1930), the Bay of Biscay, off Spain and Morocco (Locard, 1897; Dautzenberg, 1927). In the arctic area it occurs in 5-500 m, in the southern parts in 400-2000 m. Remarks: We have not seen E Siberian or N Pacific material of the species and do not exclude that the records from these areas can be ascribed to misidentifications (cf. Odhner, 1915). We have selected a specimen from the collection of Chemnitz as lectotype. It does not agree very well with the figure in Chemnitz (1780), but Chemnitz had already criticized the figures for not resembling his specimens. Mohr’s (1786) validation of the name was based on Chemnitz’s figures which therefore have to be considered types. The size of C. islandicus is highly variable. It reaches a maximum size of about 200 mm, but we have seen deep-water specimens of 90 mm that evidently are full-grown. Specimens from the Bay of Biscay and southwards are more slender and solid than arctic specimens. The development was described by Thorson (1935), who gave figures of egg capsules and young specimens. C. islandicus hatches at a size of 5-8 mm. C. islandicus can be recognized from its large size, unusually inflated larval whorl, the oblique suture and the long, straight, siphonal canal. 230 P. BOUCHET & A.

Type locality: F. jeffreysianus, Arcachon, Gironde, SW France. Material examined: About 600 specimens from all parts of the distribution area. Distribution: From the Kattegat and SW Skagerrak (20-200 m, Petersen, 1888, ZMC), the British Isles, Shetland (Seaward, 1982; Massy, 1930), the Faroes (unpublished material ZMC) and S Iceland in deep water (400-2100 m, unpublished material in ZMC). From the British Isles southwards on the continental shelf and slope S to Casablanca (Morocco) and into the Mediterranean, at least to the Alboran Sea (Locard, 1897; material in MNHN), possibly also S France (Monterosato, 1877). Remarks: C. jeffreysianus is an extremely variable species which has given rise to a prolific synonymy. In S Scandinavia and N Great Britain including the Shetlands, the predominant form is small, solid, with convex whorls and a rather coarse periostracum. The name howsei was based on this form. Off W Great Britain and Ireland this form goes over into typical jeffreysianus, which is larger, higher, has flatter whorls and a thinner periostracum. This transition has already been pointed out by Marshall (191 1) and Massy (1930), but has never been accepted in the literature. The jeffreysianus form occurs mainly in 100-200 m and is distributed southwards to the Spanish N coast, where it goes deeper and becomes smaller. In the area off N Great Britain the howsei form becomes more slender, more cylindrical and gets a thinner periostracum when it is found in deeper water, the attenuata form (Fig. 622). This is a continuous change and we have observed a similar change in the Bay of Biscay from typical jeffreysianus, via the torra and pupoidea forms to typical attenuatus (cf. Figs 624, 626-628). There cannot be put any sharp upper limit for the attenuata form, but usually it ocdurs below 1000 m, while specimens from 200-1000 m are usually transitional between jeffreysianus and attenuatus. Thorson (1944) excluded C. jeffreysianus from the Greenlandic fauna, which we find correct. There are a few specimens in ZMC labelled “Greenland” by Moller, but they belong to the Kattegat form of howsei and there is no doubt that the labels are erroneous. Locard (several papers) reported C. jeffreysianus from “Provence”, but we have not seen any material in his collection. Monterosato (1877) discussed the occurrence of C. jeffreysianus in the Mediterranean and wrote that Martin’s (Jeffreys, 1867) record of Fusus buccinatus from the stomach of Trigla gurnardus (Pisces), from Golfe du Lion, S France was based on C. jeffreysianus. He also mentioned that he had often found broken specimens in that fish, and referred Crosse’s record (1875) of two specimens of Fusus gracilis from Golfe du Lion to C. jeffreysianus. It seems therefore that the species occurs further into the Mediterranean than our material indicates. Thorson (1946) described the larval development under the name Sipho propinquus. Colus jejfreysianus and C. gracilis are often quite difficult to separate. When the larval shell is present they can easily be distinguished {cf. figs 604-605, 629-630), but this is often corroded. Then one can use the general shape of the shell, which is more slender, with flatter whorls in C. gracilis, but often it is necessary to wait until one gets some young specimens with preserved larval shell from the population in question, especially if the specimens come from deep water. NORTH-EAST ATLANTIC NEOGASTROPODA 231 Colus kroeyeri ( Moller, 1842) Figs 631-633 Fusus kroyeri Moller, 1842:88. Fusus arcticus Philippi, 1850:119, pi. 5, fig. 5. Fusus (Tritonofusus) kroeyeri vars major & pumila Morch, 1869:19. Plicifus johanseni Dali, 191 9:21 A. Type material: F. kroeyeri, lectotype, here selected, in ZMC. Type locality: F. kroeyeri, W Greenland. Material examined: The type and the material listed by Thorson (1944, 1951) and Odhner (1915) and about 25 samples scattered over the N Atlantic part of the range (MNHN, SMNH, USNM, ZMC). Distribution: Circumpolar in 0-200 m (Macpherson, 1971). Not present in Norway (Sars, 1878) or Iceland (Thorson, 1941). Remarks: We have included this species to make the ennumeration of N Atlantic species of Colus complete. There are no species in the N Atlantic that are easily confused with C. kroeyeri. The distinct axial ribs in combination with the brownish shell make it easily recognizable. Fusus cretaceus Reeve, 1847 has usually been synonymized with C. kroeyeri but Cernohorsky (1977: Rec. Auckland Inst.Mus. , 14:97) has shown that it is a synonym of the New Zealand muricid Xymene ambiguus (Philippi, 1844).

Type material: F. latericeus, lectotype, here selected, in ZMC. Type locality: W Greenland. Material examined: The material enumerated by Thorson (1941, 1951) and Odhner (1915) and a few additional localities from the known distributional area. Distribution: Along the W Greenland coast, Jan Mayen (absent from E Greenland) (Thorson 1944, 1951), NW and N Iceland (Thorson, 1941), N Norway (G.O. Sars, 1878), Spitzbergen (Odhner, 1915) and Barents Sea, in 20-200 m. Remarks: This is a coast and shelf species, but we have included it to make this a complete treatment of the N Atlantic species of Colus. It has been recorded from 1 187 m (Friele, 1882) but this record is based on an empty shell. Fusus pertenuis (holotype BMNH 1885.11.5.2931) was based on an unusually slender and thin specimen, but the sculpture and apex are normal. C. latericeus may be recognized by the reddish brown shell (occasionally colourless), the sculpture of strong spiral lines and axial ribs and its small size. Colus pubescens (Verrill, 1 882) Figs 465,639-640 Sipho pubescens Verrill, 1882:501, pi. 43, fig. 6, pi. 57, fig. 25. Type material: Three syntypes, USNM 37767. Type locality: USFC st 793, off Newport, Rhode Island, 35 m. Material examined: Many hundred specimens, from off Daytona, Florida, to Newfoundland, 20-800 m (USNM). Distribution: As above. 232 P. BOUCHET & A. WAREN Remarks: C. pubescens has often been confused with C. stimpsoni, but differs by having a smaller larval shell and a hairy periostracum; it is more slender and has more convex whorls than stimpsoni. It also resembles C. gracilis very much, but that species has a smooth periostracum. Macpherson (1971) recorded C. pubescens from arctic Canada, but her figure (pi. 5, fig. 1) clearly shows a specimen of C. sabini, so we consider her record uncertain.

Type material: All lost. Type locality: F. pygmaeus, “In fish, our harbour” (Boston, Massachusetts). Material examined: A few hundred shells and specimens from all parts of the distribution area. Distribution: From Gulf of St. Lawrence to North Carolina, NE America, in 1 — 1100 m (Abbott, 1974). Remarks: There seem to be no problems with the identity of this species, but the young looks rather different from the adult specimens (Figs 641, 642). We have, however, seen two more forms, one from Florida (Fig. 644) and one from off N. Carolina (Fig. 645), which differ from pygmaeus by their larger size and more straight columella. These two forms also resemble C. jeffreysianus, but we consider them too imperfectly known to allow any further speculations.

Type localities: B. sabini, NW Arctic Atlantic; F. reeveanus, presumably the Newfoundland Banks. Material examined: About 400 specimens from all parts of the N Atlantic range, USNM, ZMC, SMNH, ZMB, MNHN. Distribution: From arctic Canada (Macpherson, 1971 as pubescens and togatus) south to 150 miles S of Cape Race, Newfoundland (unpublished in USNM), W Greenland (Thorson, 1951, as togatus ), E Greenland (Thorson, 1944, as curtus ), N and E Iceland (Thorson, 1941, as togatus ), between Shetland and the Faroes (Jeffreys, 1883, as hirsutus ), Spitzbergen (Odhner, 1915, as hanseni, togatus and hirsutus), Novaja Zemlya (Leche, 1878, as sabini) and the Laptev Sea (Aurivillius, (1885). Absent from Norway (Friele, 1882). It occurs in 5-1200 m, normally 100-600 m, in high arctic areas in more shallow water. Remarks: Some developmental stages were described by Thorson (1935) under the name S. curtus. The young live on nurse eggs and hatch at a size of 5 mm. C. sabini is quite variable, both in size (max. 83 mm, the type of reeveanus) the solidity of the shell, and the sculpture. A good help in recognising it is the sculpture, which consists of alternating strong and weak spiral ribs. Usually the apical whorls are completely corroded. The parietal callus is NORTH-EAST ATLANTIC NEOGASTROPODA 233 often very solid in adult specimens and sometimes there is an umbilical chink. We are not aware why Macpherson (1971) considered Buccinum sabini a nomen dubium. We have selected a neotype from an old sample labelled sabini and collected by Sabine. The description is not less precise than that of most other species described at the same time. Colus stimpsoni (Morch, 1867) Figs 463, 653-657 Fusus striatus Reeve, 1847:sp. 42 (not Sowerb^ 1828).

Type material: F. stimpsoni, neotype, here selected, in ZMC. Type locality: F. stimpsoni, “Shores of New Jersey”, NE US. Material examined: Several hundred specimens from all parts of the distributional area, mainly in USNM. Distribution: Labrador to off N Carolina, 2 — 850 m (Abbott, 1974). Remarks: C. stimpsoni is a highly variable species. The short broad form (Fig. 653) has often been confused with C. terraenovae and has a more N and shallow distribution, from the New England area northwards. All intermediates between this form and the more slender, more southern and deeper form (Fig. 655) exist. C. stimpsoni may be recognized from its smooth, shiny, naked periostracum and usually very solid shell. These features are shared with C. terraenovae but that species has a smooth, multigyrate larval shell and is still shorter and broader even than the form from the Banks. To stabilize the nomenclature, we have selected a neotype from the Morch collection in Copenhagen. The development and reproductive anatomy were described by West (1973, 1978). Colus terraenovae nom.nov. Figs 413, 462, 658-660 Fusus ventricosus Gray, 1839:117 (not Anton, 1838). Type material: Two syntypes in BMNH, no reg. no. Type locality: Not mentioned, here restricted to Newfoundland Banks. Material examined: About 40 specimens from the Newfoundland Banks. Distribution: Uncertain because of confusion with the short forms of C. stimpsoni. We have only seen reliable records from the Banks around Newfoundland, in 40 — 150 m. Verrill (1882) considered the records from New England doubtful. Remarks: Colus terraenovae has very often been confused with the short, stout forms of C. stimpsoni. This is probably the reason why it has been recorded from the NE U.S. (Abbott, 1974) and as a fossil from Great Britain (Pain, 1981). They can, however, easily be distinguished by the outlines of the spire, which are convex in terraenovae and concave in stimpsoni. Also the larval shells are widely different: that of terraenovae consists of 2-3 smooth, distinctly set off whorls while that of stimpsoni is not distinctly set off, starts with a large initial whorl and has a rough surface (Figs 657, 660). The name ventricosus under which it has been usually known is preoccupied by Anton’s (1838) use of the name and it has to be given a new name. The date of publication of Anton’s catalogue was discussed by Cernohorsky ( Veliger , 1978, page 299), who showed that it had already been published in 1838 instead of 1839 as generally supposed. 234 P.

Distribution: Along the slopes of the Norwegian Basin, from between Norway and Spitzbergen, to the Shetland-Faroe Channel and E Iceland, in 400—1100 m. Remarks: Colus turgidulus is a characteristic species but resembles Buccinum more than Coins at the first glance. The operculum is, however, not of Buccinum type but normal for a species of Colus, as is also the radula. The fine spiral sculpture is present only on the first postlarval whorls. Thorson’s var. minor of C. turgidulus was based on specimens of C. gracilis and the species is thus not known from Greenland.

Remarks: Macpherson (1971: pi. 5, fig. 6) figured a specimen that she had reluctantly determined as C. verkruezeni, from NE Canada. We agree that it probably does not represent that species. Golikov & Scarlato (1977) identified B. brucei with C. latericeus, but the very short siphonal canal and the size (41 mm) indicate that it must be a synonym of C. verkruezeni. C. altus (S. Wood, 1842) from the British Crag Formation, resembles C. verkruezeni closely, but we hesitate to consider them conspecific. NORTH-EAST ATLANTIC NEOGASTROPODA 235 Figs 587-591.

NORTH-EAST ATLANTIC NEOGASTROPODA 249 Family OLIVIDAE Genus BENTHOBIA Dali, 1889. Type species : Benthobia tryoni Dali, 1889 (by monotypy). Synonym: Nux Barnard, 1960. Type species N. alabaster Barnard, 1960 by original designation. Remarks: Dali originally suggested a cancellariid affinity for Benthobia and the genus remained placed in this family without any particular reason. We have examined the radula of a specimen of the type species and found it to be a rachiglossan type. The presence of the spiral sulcus on the body whorl recalls that of several Olividae grouped as Pseudolivinae, both Recent, such as Fulmentum sepimentum (Rang), and fossil, such as Pseudoliva elisae Briart & Cornet figured in Glibert (1973, pi. 9), and several species figured by Cossmann & Pissarro (1907-1913, pi. 36, figs 177-1 - 3). We also figure the radula of the Recent Fulmentum sepimentum from West Africa, for comparison with Benthobia (Figs 669-670). In the original description of Nux, Barnard noted a resemblance to Benthobia but assumed they belonged to different superfamilies because Benthobia was then believed to be a cancellariid and Nux had a rachiglossate radula. Barnard did not locate Nux in a family. Benthobia tryoni Dali, 1889 Figs 665-668 Benthobia Tryonii Dali, 1889:132, pi. 35, fig. 6. Lacuna cossmanni Locard, 1897:493, pi. 22, figs 4-9.

NORTH-EAST ATLANTIC NEOGASTROPODA 251 Family VOLUTOMITRIDAE The family was revised by Cernohorsky (1970) and two additional Atlantic species were described by Bayer (1971). We have moved the genus Latiromitra to Turbinellidae after examination of the radula, and we describe a new species of Microvoluta from the Josephine sea-mount. Most Volutomitridae are known from very few specimens. Genus Volutomitra H. & A. Adams, 1853 Type species: Mitra groenlandica Beck in Moller, 1842, subsequent designation Fischer, 1884. Remarks: In our material Volutomitra is represented by two species, of which we leave one undescribed. The genus is mainly known from Arctic, Antarctic and Subantarctic areas. Volutomitra groenlandica (Beck in Moller, 1842) Figs 391, 671-672 Mitra groenlandica Beck in Moller, 1842:88. Type material: Numerous syntypes in ZMC. Type locality: W Greenland.

Distribution: The N North Atlantic upper bathyal zone, in arctic areas also coastal waters; Canada (Macpherson, 1971), E and W Greenland (Thorson, 1944, 1951), Iceland (Thorson, 1941), off Ireland (Massy, 1916), the Faroes (Sparck & Thorson, 1933), Norway N of Lofoten (G.O. Sars, 1878), Spitzbergen (Odhner, 1915), Novaya Zemlya (Golikov, 1964). Depths 7 — 773 m, usually 20—100 m. Remarks: V. groenlandica is quite variable in the shape of the shell and the colour. Arctic specimens tend to be more light brown while southern specimens are more greyish. We have examined the material found off Ireland by Massy (1916) and one specimen looked recently dead; other findings from southern localities may be subfossil. Volutomitra sp. Fig. 673 We figure a shell from THALASSA st Z424, 48°28 N, 09°44 W, 475 m, that does not agree with any form of V. groenlandica we have seen. It is a rather fresh-looking shell and it differs from V. groenlandica by having flatter whorls, being more slender and by having a grey shell. It may be an undescribed species, but it may also be a more southern form of groenlandica. It is, however, unusual for species that occur in arctic shallow water to go so far to the south. 252 P. BOUCHET & A. WAREN Genus MICRO VOLUTA Angas, 1877 Type species: M. australis Angas, 1877, by monotypy. Remarks: The related genus Conomitra Conrad, 1865 is represented by numerous fossil species in the lower Tertiary beds of Europe. The species described below is the first of this group known from the NE Atlantic as Recent. Microvoluta superstes sp.n. Fig. 674 Type material: Holotype and 18 paratypes in MNHN. Type locality: NORATLANTE st E9, 36°41 N, 14° 15 W, 208-230 m. Material examined: Only known from the type material. Description: (Holotype) Shell white, glossy, consisting of 5.5 slightly convex whorls, with a well- marked suture; protoconch of one globular smooth whorl; postlarval sculpture of strong axial ribs of which 12 and 1 1 can be counted on the body- and penultimate whorl respectively; postlarval spiral sculpture of rather deep grooves of which there are two below the suture and nine at the base of the body whorl; at the base of the shell these spiral grooves are more closely-spaced and form granules where they cross the base of the axial ribs; there is a narrow concave columellar zone; three columellar folds of which the lowermost one is very oblique; outer lip thin, siphonal canal short. Dimensions of the shell height: 5.55 mm, breadth 2.45 mm; height of the aperture 2.5 mm, breadth 1.1 mm. Some paratypes lack the spiral threads below the suture, while in others the spiral sculpture is present even at the middle of the whorls. Remarks: All shells are empty, and most of them were bored by naticids. Because no animal is available, the generic placement is only tentative. NORTH-EAST ATLANTIC NEOGASTROPODA 253 Figs 671-676.

BOUCHET & A. WAREN Family TURBINELLIDAE The family Turbinellidae contains two genera present in the deep water of the NE Atlantic. A third genus, Ptychatractus Stimpson, 1865 is represented by a single species in the NW Atlantic, in shallow water. Several tropical species are known from the deep shelf or upper continental slope. Genus METZGERIA Norman, 1879. Meyeria Dunker & Metzger, 1874:150 (non Meyeria McCoy, 1849). Type species: Lathyrus albellus Dunker & Metzger, 1874, by monotypy. Metzgeria Norman, 1879:56, new name for Meyeria Dunker & Metzger, non McCoy. Remarks: Metzgeria includes three NE Atlantic species, all living in deep water, of which M. gagei is here described as new. M. apodema Bouchet & Talavera, 1981 has a solid broad teleoconch and a multispiral larval shell. M. alba (Jeffreys, 1873) and M. gagei n.sp. have a paucispiral larval shell and more hidden columellar folds. M. gagei is smaller, more slender and fragile than alba. Metzgeria decorata (Locard, 1897) is a synonym of Fusinus amiantus (Fasciolariidae). Metzgeria alba (Jeffreys in Wyville-Thomson, 1873) Figs 393, 677-678 Tritonium pusillum M.

AW. Distribution: On the shelf and upper continental slope, from Davis Strait (see above), Iceland (Oskarsson, 1962, 1967; Thorson, 1941), the Faroe Channel (Thomson, 1873) and along the Norwegian coast, N to Finmarken (G.O. Sars, 1878), in 100-1960 m. Remarks: Metzgeria alba was recorded from the Azores (Locard, 1897), but the specimen in question proved to be an undeterminable fusinid, possibly Fusinus amiantus. M. alba is quite a rare species, except possibly along the Norwegian west coast. Metzgeria gagei sp.n. Figs 389, 679-68 1 Type material: Holotype RSM 1981089-13002. Type locality: Challenger II 1981 st 30, 58°18 N, 14°31 W, 670 m. Material examined: The type material and INGOLF st 10, 64°24 N, 28°50 W, 1484 m, 3 shs; st 81, 61°44 N, 27°00 W, 913 m, 1 sh; st 18, 61°44 N, 30°29 W, 2137 m, 2 spms. Description: Shell whitish, fragile and slender. The larval shell consists of a little more than one, rather inflated whorl, sculptured with some indistinct traces of spiral lines and its height is 1.1 mm. The holotype has 7.3 postlarval whorls which are slightly shouldered and not very convex. The lower whorl lacks this shoulder and is evenly convex. The sculpture consists of low spiral ribs absent on the shoulder, and on the upper whorls rather strong, sharp axial ribs distinctly angled at the edge of the shoulder. On the body whorl the axial sculpture becomes much fainter and looks more like incremental lines. The columella is long and slender and sculptured by incremental lines. There are two distinct columellar folds, which are not visible when looking straight at the aperture, but only when the shell is rotated about 1/6 of a whorl clockwise. The outer lip is straight and thin. Dimensions: Height of the shell 28.0 mm, diameter 8.1 mm, height of the aperture 13 mm, breadth 3.2 mm. NORTH-EAST ATLANTIC NEOGASTROPODA 255 Remarks: The operculum is almost straight, rather thin and yellowish. This new species differs from M. alba in having a less solid shell, sharper apical axial ribs, a proportionally larger larval shell (compared with the subsequent whorl), and by having a more slender aperture. Comparison with specimens of M. alba from similar depths and adjacent localities from the Ingolf expedition, show the same differences, so it can be concluded that M. gagei is not a geographical or deep variety.of M. alba. Metzgeria costata (Dali, 1890), from the Lesser Antilles, 1220 m, has stronger columellar folds, easily visible in the apertue and a proportionally higher aperture. Metzgeria apodema Bouchet & Talavera, 1981 Fig. 682 Metzgeria apodema Bouchet & Talavera, 1981:177. Type material: holotype in MNHN. Type locality: METEOR st 36-98, 25°31 N, 16°02 W, 700-900 m. Distribution: Only known from the holotype. Remarks: M. apodema differs from the two other species of Metzgeria from the area by its multispiral larval shell, and its broader teleoconch with shouldered whorls. Genus LA TIR OMITRA Locard, 1897 Type species: L. specialis Locard, 1897, by monotypy. Synonym: Cyomesus Quinn, 1981. Type species Mesorhytis meekiana Dali, 1889. Remarks: The systematic position of Latiromitra has been changed several times. Locard placed it in Pisaniidae (i.e. Buccinidae!). Thiele (1929) transferred it to Costellariidae. Cernohorsky (1970) considered it a subgenus of Volutomitra, hence a volutomitrid. The radulae of two conchologically very similar species, Teramachia chaunax Bayer, 1971 and Mesorhytis meekiana Dali, 1889 have been described by Bayer (1971). They are of turbinellid type and Bayer concluded that the species belonged to the Turbinellidae. He therefore moved Teramachia to Turbinellidae. The type species of Teramachia, however, is T. tibiaeformis Kuroda, 1931, of which the radula has been figured by Habe (1952). There seems to be no doubt that the type species is a volutid. Rehder (1972) and Cernohorsky (1973) suggested that T. chaunax, Mesorhytis meekiana and two other species, Mesorhytis costatus Dali, 1890 and Teramachia barthelowi (Bartsch, 1942) should be placed in Benthovoluta Kuroda & Habe. Finally Quinn (1981) considered these species distinct enough to separate them from Benthovoluta and suggested a new genus, Cyomesus, with meekiana Dali as type species. We have examined the radula of T. barthelowi (Fig. 390) from the Philippines and can confirm its affinity to chaunax and meekiana. We cannot, however, see any conchological differences between these four species and Latiromitra that can be used to maintain two genera, and consider Cyomesus a synonym of Latiromitra. Presumably no one considered Latiromitra as a genus for these species because it was considered a volutomitrid. Mitra bairdi Dali, 1889, from the bathyal area off N Carolina and the Gulf of Mexico is a typical mitracean, as we found from examination of the radula. Latiromitra cryptodon (P. Fischer, 1882) Figs 675-676 Mitra cryptodon P. Fischer, 1882:273. Latiromitra specialis Locard, 1897:321, pi. 14, fig. 30-34. Type material: The two names are based on the same two syntypes in MNHN.

Distribution: Only known from the material examined. Remarks: The larval shell is multispiral and probably indicates planktotrophic larvae. 256 P. BOUCHET & A. WAREN Figs 677-682.

NORTH-EAST ATLANTIC NEOGASTROPODA 257 Family CANCELLARIIDAE Our collection of cancellarids is rather small. The family is not common in deep water, judging from the literature. Clarke (1962) cites five species from below 1830 m (of which Admete aquilarum (Watson) is a turrid). A few species have been described by Barnard (1960), Okutani (1964), Dali (1908), Verrill (1885) and Knudsen (1964). Several cancellarids were originally described as trichotropids. The genus Benthobia which previously has been placed in Cancellaridae is here transferred to Olividae (p.249). Genus ADMETE Kroyer in Moller, 1 842 Type species: A. crispa Moller, 1842 ( = Tritonium viridulum Fabricius, 1780) by monotypy. Remarks: There has been a controversy about the type species of Admete , since Dali (1887) wrote that Tritonium viridulum Fabricius and Defrancia viridula Moller, 1842 were based on the same specimen and suggested that T. viridulum was a turrid. European authors have continued to use the name of Fabricius, while American authors have used the name Cancellaria couthouyi Jay, 1839 (replacement name for Cancellaria buccinoides Couthouy, 1838, not Sowerby, 1832). Dali (1887) pointed out that this had been mentioned by Morch and that he had examined the specimen in Copenhagen. Morch never mentioned this in any paper and even the last time he used the name viridula (1877) shortly before his death, he used it in the accustomed sense. Posselt (1895) mentioned Dali’s doubts on the validity of the name viridula and that it was caused by a catalogue note by Morch, but evidently Posselt considered it of no importance, because he continued to use the name Admete viridula. At this time there were no types of Admete crispa Moller or Tritonium viridulum Fabricius in the museum, because they were not mentioned by Posselt and he always listed the type material when it had been found. (There is, however, still alcohol material determined “ Admete viridula Fabricius” by Moller.) Therefore we suppose that Moller (1842) had misidentified Fabricius’s Tritonium viridulum and later, when he realized this, began to use this name for his former Admete crispa. The original description (Fabricius, 1780) also supports our view that T. viridulum was not based on a turrid, especially the comparison with Buccinum undatum and the mention of a very short siphonal canal. To stabilize the nomenclature, we have therefore selected one of Moller’s specimens as neotype of T. viridulum (Fig. 683). This solution will make it possible to keep the name, which has been used in a single sense in Europe for 200 years. The genus Admete contains a few species from high northern and southern latitudes. Many of the species which have been placed here, actually belong to other groups. We have included three species in Admete, the type species and A. nodosa and A. azorica. The two last-mentioned species probably do not belong to Admete, but we have not been able to find a genus for them among the numerous cancellariid genera that have been described and we hesitate to introduce a new name before the other names have been thoroughly revised. Therefore we have kept them here. 258 P. BOUCHET & A. WAREN Admete viriduia (Fabricius, 1780) Figs 683-689 Tritonium viridulum Fabricius, 1780:402. Murex cos tel lifer Sower by, 1818:225.

AW. Distribution : From Massachusetts to Arctic Canada (Macpherson, 1971), E and W Greenland (Thorson, 1944, 1951), Iceland (Thorson, 1941), the Faroes (Spate k & Thorson, 1933), deep water off the British Isles (Jeffreys, 1885; Jordan, 1895; Sykes, 1911; Massy, 1930), along the Scandinavian coasts (G.O. Sars, 1878), Spitzbergen (Friele, 1886; Odhner, 1915), Kara Sea and Novaya Zemlya (Leche, 1878). In arctic areas A viriduia occurs in shallow water, from intertidaily, down to 1100 m (Friele, 1886), in the southern parts of its distribution considerably deeper, in S Scandinavia in 75-1200 m. Probably A. viriduia has a panarctic circumpolar distribution. Remarks : For discussion about the specific name, see under the genus. Admete viriduia is extremely variable, which is reflected in the large number of varieties that have been described. Probably also several names from the N Pacific should be added but that is beyond the intention of our work. Young specimens of A. viriduia may easily be confused with young Oenopota spp., but Oenopota has a more slender aperture, distinct siphonal canal, and an operculum. Nordsieck (1968) considered A. inf lata (see Iphinopsis ) as a subspecies of A. viriduia , but that is not because they are similar, but because he had never seen A. inf lata. Thorson (1944) referred the egg capsules he had previously (1935) assigned to Velutina undata » to Admete viriduia. We can confirm this observation and figure egg capsules and young from W Norway.

Distribution: Only known from the material examined, from the Azores. Description: Shell short, conical, rather broad, very solid, white. The larval shell consists of 2.25 whorls, sculptured by fine spiral lines and its height is about 850 pm. The holotype has 2.8 postlarval whorls which are rather flat and sculptured by strong axial ribs; 1 1 ribs occur on the body whorl. There are also numerous irregular growth lines. The spiral sculpture consists of three often interrupted spiral lines on the upper whorls and two additional ones on the body whorl. The aperture is rather small with two large columellar folds and a strongly oblique outer lip. NORTH-EAST ATLANTIC NEOGASTROPODA 261 Dimensions: Height of the shell 7.6 mm, diameter 4.6 mm, height of the aperture 4.0 mm, breadth. 2.1 mm. Remarks: A azorica differs from A. nodosa by its more slender shell and possibly its larval shell has about half a whorl less, but this could not be positively ascertained because of the poor preservation of all larval shells of A. nodosa. Furthermore, it reaches only half the size of A. nodosa. Genus IPHINOPSIS Dali, 1924 Type species: Iphinoe kelseyi Dali, 1908, by original designation (Fig. 694). Synonym: Iphinoella Habe, 1958.

Remarks: Iphinopsis has previously, from shell characters, been placed in Trichotropidae, but on evidence given below we transfer it to Cancellariidae. There have been described several species resembling I. kelseyi in various families and genera: Trichotropis inf lata Friele, 1879, from deep water N of Norway. Trichotropis nuda Dali, 1927, from deep water off Florida (Fig. 704). Iphinoella choshiensis Habe, 1958, off Japan, 500-1500 m. Tromina traversensis Clarke, 1959, from the abyssal S Atlantic. Cancellaria euthymei Barnard, 1960, from off S Africa. We have examined specimens of kelseyi, inflata, nuda, traversensis and two species that are described as new here, and found them to be very similar conchologically. We have also examined the anatomy of four of these, inflata, traversensis and the two new species. They were identical, except in the development of the eyes and sexual characters. The examination was made on dried specimens reconstituted by soaking in a water detergent solution, and we noticed that after soaking, all were extremely slimy and that the oviducts had swelled, producing a lot of mucus. The foot is large and muscular and probably very large when the animal is crawling. The propodium is distinct and there is no operculum. The tentacles are short and rounded with eyes situated laterally at their base. The osphradium is large, bipectinate, of at least the same size as the gill. The animal has no snout, a long pleurembolic proboscis with two pairs of salivary glands, but no radula. No identifiable contents were found in the rectum or intestine. The diameter of the eyes of I. traversensis was 40 pm, of alba 100 pm, of inflata 130 pm and of fuscoapicata 150 pm, in specimens of the same size. The specimens of inflata, traversensis and fuscoapicata were females with a well-developed pallial oviduct, while two specimens of I. alba had both penis and pallial oviduct. From these anatomical details and the presence of columellar folds, we conclude that the species belong to Cancellariidae. Iphinopsis choshiensis Habe is the type species of Iphinoella Habe and I. kelseyi Dali, is the type of Iphinopsis. Habe (1962) synonymized the two genera and considered them to belong to Trichotropidae, which we find untenable on the basis of absence of radula, absence of operculum, absence of snout, presence of pleurembolic proboscis and presence of columellar folds in the species we have examined. We admit that we have not examined the animal of either of the two type species, but conchologically they are very close to those which we have examined. The species of Iphinopsis are easy to confuse with other groups of gastropods, as is evident from the known species being described in three different families. Clarke (1961) pointed out that T. traversensis could be confused with the young of Oocorys, but described it as a buccinid in the genus Tromina Dali, 1918 (Fig. 328), probably misled by Powell (1951) who used Tromina for certain antarctic buccinids. Iphinopsis can also be confused with the young of some cassids, some buccinids and trichotropids. The species of Iphinopsis can, however, be distinguished by having columellar folds, which may be very indistinct and visible only rather far back in the aperture. Some turrids of the genus Lusitanops also resemble Iphinopsis, but they have a less well developed umbilicus and a larval shell with cancellate sculpture. 262 P. BOUCHET & A.

Distribution: Only known from between Norway and Spitzbergen and around Iceland, from the material examined. VerrilFs (1884) record from off New England in 3200 m needs confirmation and we were not able to locate his material in USNM. Remarks: I. inflata differs from /. alba by having less developed, almost invisible columellar folds, while those of /. alba are very distinct, especially the lowermost one. It differs from I. fuscoapicata by having a white larval shell of about one whorl, instead of a brownish, multispiral larval shell. To see the columellar folds of I. inflata it is necessary to look rather obliquely into the aperture. Iphinopsis fuscoapicata sp.n. Figs 700-703 Type material: Holotype in MNHN.

Distribution: Only known from the material examined, off the British Isles, ca. 2500 m. Description: Shell of medium size, fragile, inflated, dirty white. The larval shell is dark brownish and consists of about two whorls, sculptured by faint spiral striae, and its height is about 650 pm. The holotype has about three postlarval whorls of rather rapidly increasing diameter. The sculpture consists of equidistant spiral cords, weaker on the lower part of the body whorl and almost disappearing at the columella. The axial sculpture consists of a few stronger and numerous small, sharp incremental ribs. The stronger ribs appear at irregular intervals, the smaller ones are close set and regularly spaced. The outer lip, seen from the side, is slightly sigmoid. The inner lip forms a far- protruding, evenly-curved parietal callus, continuous with the reflected part of the columella and forming a deep umbilical chink behind it. There is no distinct siphonal canal. Dimensions: Height of the shell 9.5 mm, diameter 6.0 mm, height of the aperture 6.0 mm, breadth 2.9 mm. Remarks: The present species can be distinguished from the two other species known from the NE Atlantic by the larval shell, which is brownish in I. fuscoapicata and white in the others. /. traversensis probably has a brownish larval shell, but the apex of the holotype is badly corroded, so we could see only traces of this, in the old sutures. It differs from /. fuscoapicata by having a finer and less distinct axial sculpture with more distant ribs and by having more convex and strongly shouldered whorls. There is hardly any columellar fold visible in the specimens we have examined, but this may be because our specimens are not full grown.

Distribution: Only known from the continental slopes of the bay of Biscay and the Rockall Trough, 1900-2900 m. Description: Shell of medium size, rather inflated, fragile, whitish, or dirty whitish. Larval shell white, sculptured by a few rather coarse spiral lines, consisting of about 1 .2 whorls and of a height of 600 ^m. The holotype has about 4 postlarval whorls, but this figure is uncertain because of corrosion of the spire. The sculpture is identical to that of fuscoapicata, possibly some specimens have coarser axial sculpture, but this is difficult to ascertain from our small sample. The shape of the aperture and the columella are also identical with fuscoapicata. Dimensions: Height of the shell 14.5 mm, diameter 8.2 mm, height of the aperture 9.5 mm, breadth 3.8 mm. Remarks: Iphinopsis alba can be separated from /. fuscoapicata only by the larval shell (Figs 697, 702), which in /. alba has coarser sculpture, about 3/4 of a whorl less, and is white instead of brown. Another difference, more difficult to see in juvenile specimens, is that /. alba has distinct columellar folds while /. fuscoapicata has no trace of them. This is also the only difference from /. inf lata where only traces of one fold can be seen. Genus OLSSONELLA Petit, 1970 Type species: Cancellaria smithi Dali, 1883, by original designation. Remarks: The type species was described from shallow water (35-80 m) off N Carolina. Dali (1889) compared this species with Cancellaria minima Reeve, because of their similarity. We have used the genus Olssonella on the advice of Mr R.E. Petit, with whom we have had valuable discussions about the cancellariids. Olssonella minima (Reeve, 1856) Figs 692-693 Cancellaria minima Reeve, 1856: sp. 77. Type material: Syntypes in BMNH. Type locality: No locality mentioned. Material examined: The types and: off Madeira, 410-580 m, 1 sh, MNHN; PORCUPINE 1870, off Cadiz, SW Spain, 700 m, 7 shs, BMNH. Distribution: The area W of Gibraltar, kriown from 600-700 m; Madeira, in shallow water (Watson, 1897). Remarks: Cancellaria minima was described by Reeve without giving the locality but Jeffreys (1885) said that the specimens originated from the dredgings of McAndrew and recorded it from Gibraltar and Madeira on the authority of McAndrew. McAndrew (1852, 1857) also listed undescribed cancellariids from Madeira and the Canaries. As Watson’s (1897) records from Madeira indicate, this will probably prove to be a shallow-water species. 264 P. BOUCHET & A. WAREN Figs 690-693.

NORTH-EAST ATLANTIC NEOGASTROPODA 267 Family MARGINELLIDAE Examination of literature suggests that marginellids seem to be scarce in deep water (Clarke, 1962 lists four species). Our experience, however, is that they are not rare on the upper part of the continental slopes, especially in tropical areas. Several species of marginellids were described by Locard (1897) from just south of the area we are treating. No further material has since been found so we refer to his treatment of these species. A key to the species likely to be encountered in the area covered is presented below. A. A. B. B. C. C. D. D. E. E. F. F. G. G. H. H. I. I.

The genus Gibberula comprises small marginellids, 3-10 mm high, that live mainly on the continental shelf. Two species occur on the Atlantic slope of the Iberian peninsula, but do not enter the Mediterranean where only shallow-water species are found.

Distribution: Only known from the material examined, NW and S of the Iberian Peninsula, on the upper part of the continental slope. Remarks: G. abyssicola was reported from the Mediterranean (on the authority of Monterosato) by Locard (1897). It was however, not mentioned by Monterosato or D’Amico in any paper. G. Spada, who has examined the marginellids in the Monterosato collection has informed us that it is not present there, except two shells from the TRAVAILLEUR dredgings, nor are any specimens of retusa or monterosatoi; we conclude that there was some mistake behind Locard’s statement. The material cited from shallow water in Madeira proved to belong to Granulina. The name G. monterosatoi was based on young specimens without thickened outer lip. The specimens examined from Le Danois Bank (THALASSA X stns) show a reduction in size with increasing depth. The average size from 450 m is 4.3 mm, in 880 m, 3.3 mm. The name retusa was based on more southern specimens, which have a more thickened outer lip and solid shell. The egg capsule (Fig. 714) is a simple rounded capsule, slightly larger than the larval shell. It lies free on the bottom. The size of the young corresponds with our smallest specimens, and indicates direct development. Fig. 714. Gibberula abyssicola. THALASSA st X315, egg capsule, length 1.9 mm.

Distribution: Only known from the material examined, off Portugal and Morocco, and the Azores, on the continental shelf and upper parts of the slope. Remarks: Our experience from shallow-water species of Gibberula shows that there exists very little difference in shell characters between the species, and that living animals may be necessary to distinguish the species. We will therefore not exclude the possibility that we may have confused two species in C. vignali. Gibberula vignali differs from abyssicola by being much smaller, about 2.5—2 mm instead of 3—4.5 mm, and by having five instead of four clearly visible columellar folds. Genus GRANULINA Jousseaume, 1888 Synonym: Cypraeolina Cerulli-Irelli, 1911 Type species: Voluta clandestina Brocchi, 1814. The group of marginellids treated here has consistently been called Gibberulina in the European literature. However Gibberulina Monterosato, 1884 is a new name (“nom.sost.”) for Bui lata Jousseaume, 1875 and therefore keeps the same type species, viz. Voluta hullata Born, 1778. Bullata is a valid name and Gibberulina is an objective synonym of it. Granulina was introduced for Marginella pygmaea Issel, 1869 (type species by monotypy), non Sowerby 1846 (= Marginella isseli Nevill & Nevill, 1875) and can be used for the species formerly included in Gibberulina in Europe.

Distribution: Only known from the material examined, off N Spain and Morocco. Remarks: G. parvulina differs from the shallow-water species of the genus by being much more slender. G. occulta (Monterosato, 1869) is a deep-shelf species occasionally occurring on the upper slope in the Mediterranean and nearby Atlantic; it is figured here (Fig. 712) for comparison. 270 P. BOUCHET & A. WAREN Genus MARGINELLA Lamarck, 1799 Type species: Marginella glabella (Linne) by monotypy. The type species.of Marginella as well as four of the species discussed here lack a radula. The shape of the shell of M. glabella resembles the four species, but the colour patterns are quite different. The fifth species included in our revision, Marginella hesperia differs in shell characters; no animal was available for examination for a radula, and it seems to be more closely related to certain deep shelf species from West Africa, e.g. M. bojadorensis Thiele, 1925. Marginella hesperia Sykes, 1905 Fig. 716 Marginella hesperia Sykes, 1905: 316, pi. 17, fig. 7. Type material: 10 syntypes in BMNH. Type locality: PORCUPINE st 24, 37° 19 N, 09° 13 W, 531 m.

Distribution: On the upper part of the continental slope, from off S Portugal and Madeira. Only known from the material examined. Remarks: Marginella hesperia can be recognized by the thickenings of the outer lip, which are lacking in all other species known from the area treated. Attention must however, be drawn to M. bojadorensis Thiele, 1925 from West Africa, which has similar thickenings on the outer lip but is more slender. Marginella subturritaP .

Fischer, 1883:392. Marginella impudica var. major, var. elongata Locard, 1897:109, pi. 3, figs 19-24. Type material: Lectotype, here selected, in MNHN. Type locality: “Cotes du Sahara, 800-1139 m”. Lectotype from TALISMAN dr 81, 23° 50 N, 17° 17 W, 1139 m. Material examined: The type material and 4 spms from the type locality; TALISMAN dr 84, 22°54 N, 17°26 W, 860 m, 7 spms + shs; dr 85, 22°52 N, 17°23 W, 830 m, 1 sh, 5 spms; dr 86, 22°49 N, 17°21 W, 800 m, 5 spms, 1 sh; METEOR st 36-98, 25°31 N, 16°02 W, 700-900 m, 6 spms + shs. Distribution: The continental slope of Mauretania and former Spanish Sahara. Only known from the material examined. Remarks: The animal lacks a radula. There are eye swellings at the base of the tentacles and the unpigmented eyes measure 50 pm in diameter. Neither M. impudica nor M. subturrita has a broad thickened labial varix when seen from the side. For differences see remarks under subturrita. Marginella aronnax n.sp. Figs 720-721 Marginella impudica var. minor, var. curta and var. marginata Locard, 1897:110 (not: Marginella curta Sowerby, 1832, Marginella marginata Wood, 1828, Marginella minor C.B. Adams, 1852). Type material: Holotype in MNHN. Type locality: TALISMAN dr 84, 22°54 N, 17°26 W, 860 m. Material examined: The type material and 1 sh from the type locality; TALISMAN dr 86, 22°49 N, 17°21 W, 800 m, 7 spms, 2 shs. Description: Shell white, very solid, smooth, with a short blunt spire. The shell consists of 4.5 whorls which are very slightly convex, with a hardly visible suture. The body whorl occupies more than 3/4 of the total height. Aperture elongate, narrow with a broad thickened labial varix when seen from the side. There are four strong columellar folds of which the lowermost one is very oblique. No columellar callus. Dimensions of the shell: height 28.7 mm, breadth 14.8 mm; height of the aperture 21.2 mm, maximum breadth 3.3 mm. Remarks : The animal is blind, without eye swellings on the tentacles. It lacks a radula. Marginella aronnax is readily separated from M. impudica and M. subturrita which lack the broad thickening of the labial varix. M. marocana is smaller with a much more obtuse spire, nearly flat whorls and indistinct suture. 272 P. BOUCHET & A. WAREN Genus VOLVARINA Hinds, 1844 Type species: Marginella (Volvarina) nitida Hinds, 1844. Volvarina is here used in its conchological sense to include a new species that differs from Marginella s.s. by its more slender shell with 3 instead of 4 columellar plaits. Volvarina species have a radula while at least some of the Marginella spp. do not. Volvarina ingolf i n.sp. Fig. 715 Type material : Holotype in ZMC. Type locality: INGOLF st 92, 64°44 N, 32°52 W, 1776 m. Material examined: Only known from the holotype. Description: Shell solid, white, glossy consisting of 3.75 whorls which increase very rapidly in size; apex blunt; spire low, the body whorl forming four fifths of the height of the shell; the penultimate whorl is convex, but forms a concave slope below the suture; there are three strong columellar folds; columellar callus very thin; outer lip regularly thickened, smooth, slightly constricted in the middle. Dimensions: height 14.5 mm, breadth 7.6 mm; height of the aperture 11.7 mm, breadth 2.2 mm. Remarks: There are additional Volvarina species in deep water south of the Canaries; all of them however have a lower spire with less convex whorls, and hardly reach 10 mm. They also differ in colour patterns, the non-banded species being uniformly orange or yellowish. Volvarina ingolfi is the northernmost Atlantic marginellid.

Distribution of the species. The bathymetrical distribution is indicated in two ways, either by figures or lines. The heading indicates 100 metres intervals, and the figures the number of samples from the preceding interval. For some species of which numerous samples are known, a solid line indicates the normal distribution and a row of points scattered findings. In a few cases, there are two such lines. In these cases the upper line indicates the distribution in the northern part of the area, the lower one in the southern part, n is the number of samples examined. After the mean depth, the standard deviation is given. This gives some indication of the bathymetrical range. 294 P. BOUCHET & A.
