SCHEPMAN - Utrecht (Holland) TPAD MY Iw ACrIErOss”® With 7 plates —— ~~ § (@) (= =O 2 Dy dl leis 0 GIs iB UDLISHERS AND PRINTERS LEYDEN — IQI PART TV RACHIGLOSSA This fourth part of the Gastropoda of the Siboga Expedition, deals with the large section of the rachiglossate mollusks; it contains the enumeration of a much larger number of species than its predecessor, no less than 335 species having been recorded, of which I describe 45 as new to science, which are all figured; moreover a few new varieties of these and longer known species are described and many of them are also figured. I hope not to have exaggerated: the number of novelties, but may observe that I nearly never described a new form unless it has been compared by Mr. E. A. Smiru, I.S.O., of the British Museum, in order to avoid redescribing forms already known, especially with a view on the numerous unfigured ones of Apams. I here openly bring him my kind thanks for his never failing readiness in this respect. I have scarcely less to thank, Mr. J. Cosmo Metvitr, M.A., D.Sc. for much information in the same line and for the loan and even donation of specimens. Dr. Srurany, as acknowledged in due place in this work, sent me for comparison his new species of Nassa of the group of NV. munda etc. and in some other cases I received assistance from several persons in naming specimens and beg them all to accept my kind thanks. As to litterature, I continually could make use of the rich library of Teyler’s Museum and I am infinitely grateful to its most obliging librarian Mr. VERWIJNEN. ; As to the location of species in the sections of genera I am not quite certain I have always been right. In several cases I was able to ascertain their systematic position by examining the radulae, but in many other cases when the soft parts were wanting, 1 must make the words of Tryon (Manual of Conchology 1° series, Vol. II, p. 116) my own, when dealing with Ocinebra he says: “with regard to these I claim the indulgence of brother conchologists, who may have similarly found themselves in the predicament of being compelled to place something somewhere, just to get it off their hands”. The sections of Mitridae, Nassa, Columbella and other genera are not always limited clear enough, to avoid mistakes in this respect. ; I have on this occasion to repair a mistake in the first part of my work. In erecting - the family Neritilidae, I came to the conclusion of its difference, after the manuscript was ready, I SIBOGA-EXPEDITIE XLIx!d, ; 33 248 and omitted to place this new group after Septaria, which latter I consider to belong to the family Neritidae. My new family has been attacked by Dr. Simrors and by Prof. Tureve; the latter who had the kindness to send me his paper (Uber die Anatomie von Hydrocena cattar- oensis Pfr., in Abh. der Senckenb. Naturf. Gesellschaft in Frankf. a/M., Band 32, p. 351—358) acknowledges the genus, but is inclined to let it remain in the family Neritidae. This is one of the questions of appreciation of characters, not easy to be solved in a decisive manner, I think such a considerable difference might be sufficient, at all events the shape of the teeth, especially of that replacing the “Schirmplatte”, does not agree with the family-characters as they were limited till recently. As to Dr. Smrors, he accuses me of having divided the group into two families “on conchological characters’, as I see in his paper which I detected on p. 27 of the Proceedings of the Mal. Society of Vonden, Vol DS roxro) l) mustireply etna this accusation is quite wrong; if Dr. Simrotn had carefully read that part of my work, he would have perceived that it is only in the first place on anatomical characters, that I erected the family, for as far as I am aware, the radula is still generally considered as belonging to the anatomical side of a mollusk. If one ought to consider the radula or the genital organs to be of more importance I will not decide, but I have had so much satisfaction of my researches of the radula, that I cannot consider it as of little value. The union of Nerita and Septaria in one genus as according to SIMROTH’s paper has been accomplished by Prof. BourNE “in the first place upon the genital organs” will, I hope, not convince many malacologists, for though the splitting up of families and genera may have gone too far in many instances, I think science will not be promoted by mixing groups of such a diversified appearance of shell and operculum, even if closely allied in some ‘other respects.

I have followed Wetnxaurr, who (I. c.) says on this subject: “Die Namen O. cruenta Solander und emzcator Meuschen kénnen den .LAMARK’schen Namen nicht ausschliessen; ersterer ist Manuscriptnamen, der erst seit Dittwyn Geltung hat und die MeuscHen’schen Namen verdienen kaum Beriicksichtigung, weil sie nicht den Linne’schen Regeln entsprechen”. In accordance with this view, v. Marrens and other eminent authors have used the name gzttata. 3. Oliva rufula Duclos. IDAHO, Chis, Wilnsise, Cone, Ole, jos 22, IB ai, ie, ©, WO: REEVE.

I think fig. 8 of Rumrn (l.c.) represents this species; one of the specimens from Stat. 248, which is white, could have served as the type for this figure, which is however reversed, like many of Rumpn’s figures, the description of the “kleine glimmertjes’’ seems to cover more than one species. we 19.

Bei Exemplaren dieser letztere Species, die noch nicht durch Callus verdeckt sind, bemerkt man das rothbraune und weisse Band auf den Spira, dass bei A. trzcolor so deutlich ist.

Mr. Smiras who compared this species for me in the British Museum, writes about it: “closely allied to A. zxornata Smith” (Proc. Zool. Soc. Lond. 1879, p. 217, Pl. 20, fig. 56), but according to that figure, my new species is more convex above, the spire consequently less acute, the basal sinus is narrower and it differs in ‘colour. The great depth, combined with the different locality (¢zornata is from Japan) may argue in favour of the distinctness and give more value to the differences in the shells. I have named the species after Mr. Smitu’s christian-name. 6. Ancilla abyssecola n. sp. Pl. XVIII, fig. 5. Stat. 88. 0°34’.6 N., 119°8'.5 E. Makassar-strait. 1301 M. Fine grey mud. 5 Spec.

Mr. E. A. SmitH 1.S.O., from the British Museum, who had the kindness to compare it, writes that it is allied to but not the same as JZ. Wadkert Smith (Proc. Mal. Soc. Lond. III, p. 208, fig. 1), but that shell has a much sharper spire, the general shape is less ventricose, the aperture is narrower. The circumstance that the outer margin of aperture is smooth in the new species, denticulated in Wadkert, may be of little importance, since it is possible even probable that M. virgo might exhibit the same character if perfectly developed. 2.

Shell ovately-fusiform, white with two narrow, light rufous spiral lines on last whorl, of which the upper one runs just above the suture in the upper whorls, on the periphery in last whorl, the second line runs near the base of last whorl, making its appearance, just above the upper columellar fold; the shell is moderately strong, semipellucid, smooth and rather shining. Spire conical, with very obtuse apex, whorls about 5, nearly straight, with a slightly impressed callous suture, slightly ascending near the aperture; last whorl moderately convex at the periphery. Aperture elongate, its margin with a strong rounded varix exteriorly, interiorly thickened, with two rather strong teeth in the upper part and a few small ones (about 4) below these.

Walkerz Smith and still more to MZ. virgo, but it is thicker and less elongate than this latter species, the peristome is thickened, with some teeth interiorly, the colour is different and the sutures are much more conspicuous, the lower columellar plicae are less oblique, especially that bordering the sinus. Though some of these characters may depend on age, especially those of the peristome, I think they suffice to keep them separate. The shell is fresh and seems to have lived at the recorded depth. .

Conch.) copied by Tryon, better than with the other quoted figures. The genus, after Troscur.’s researches on the radula has been commonly classified amongst the Zoxoglossa. Prvsenrer: Introduction a l'étude des Mollusques, in: Ann. de la Soc. Roy. Malac. de Belgique, Tome 27, 1892, p. 129, has located the genus as a family between the Volutedae and Muricidae, consequently amongst the Rachiglossa. Now in 1903 Dr. Tutrrr (Die beschalten Gastrop. der deutschen Tiefsee-Exp. 1898—1899, p. 171) has found that the radula has only one row of teeth and no poison-gland, and concluded that the genus should be located near Volta. I have followed this view, though not without doubt. I found an object agreeing in general appearance with what Tuiexe (l.c. p. 172) has described as the maxilla, but the point is much longer and the basal wings are less developed than in Turete’s figure (l.c. Pl. 9, fig. 69); it seems likewise to consist of two cohering lateral parts and is very finely striated, as is the case in TurEtx’s figure (I.c. Pl. 7, fig. 69a). The shape is shown in my plate, though I must confess, that it is merely a sketch, as the object had suffered by boiling and was broken when I examined it. As to the radula, I have found another complex, agreeing with the description of TRoscureL as far as concerns the separate elements, called teeth by TRoscuet (Gebiss der Schnecken, Vol. II, p. 45, Pl. 4, fig. 11—13); their arrangement in the Siboga specimen has however more the appearance of consisting of two lateral rows, at least they lay nearly spread into two bundles, one towards the left the other towards the right side of a central line and at first give more the impression of being the two halves of a widely expanded maxilla than of a radula. 8.

I can quite agree with Mr. Smirn’s view (lI. c.) after comparing this and the preceding species, that they can be separated; amongst the- rather numerous specimens of zzczsa, I found not one that could be taken for M/. Marzae. The largest specimen from Stat. 313, having a length of 23 Mill. is quite fullgrown, with a well developed, peristome, and though the words of Apams: “labro intus sulcato’ may be exaggerated, the crenulations are visible also on part of the inner surface of lip, especially towards the base. The radula has 32 or 33 rows of teeth; the base of the median tooth (M) is nearly straight 21 268 anteriorly, curved behind, with 10 cusps, of which the median 4 ones are very long, with a shorter one, followed by two very short denticles one each side, they all are considerably longer than the base. The laterals (1) are comparatively narrow, with a strongly curved base and one very large cusp and five much smaller ones, becoming gradually smaller towards the proximal end. These teeth are very different from those figured by TroscHEL especially the long cusp of the laterals give a very peculiar character to those teeth. 9. Mitra xerampelina Melvill.

Nucleus wanting, remaining whorls 8, slightly convex, separated by a well-marked, slightly crenulated suture. Sculpture consisting of spiral grooves, which are distinctly punctured, about 15 grooves on last whorl and 4 intermediate rows of punctures in the interstices 3 to 6, moreover very fine growth-striae, somewhat coarser, nearly groove-like at the punctures are visible under the lens. The whole shell is ivory-white, with a row of subsquare yellowish-brown spots below the suture, 8 in number on last whorl; the majority of the punctured grooves, especially on the last whorl, is of the same colour. Aperture much broken, probably narrow, the intact upper part not very sharp, smooth, columella slightly curved, with 5 oblique plaits, interior white. Alt. 23, lat. 7°/,; apert. alt. about ro Mill. Though this shell is much injured, it has such peculiar characters, that I thought it might be named and described, unfortunately it has not only a rather large hole, buth the lower portion of last part of last whorl is wanting, so the shape of aperture and the measurements are in some degree uncertain. In colour and also in shape, it has resemblance with JZ. xzvea Swains., but Mr. E. A. SmirH, who compared it with that species writes: “Certainly xot xzvea Swains., which has much finer spiral sculpture. 11. Witra maesta Reeve. REEVE. Proc. Zool. Soc. Lond. 1845, p. 50. —— Conch.

Whorls 9, slightly convex, separated by a strongly marked, slightly crenulated suture, which is nearly excavated. Colour uniformly brownish-yellow, sculpture consisting of flat lirae, separated by narrower grooves, which are coarsely punctured or pitted, 6 to 7 grooves on penultimate whorl, about 22 on last whorl, of which the basal ones are but indistinctly punctured. Moreover the whole shell is covered with growth-striae and especially on the upper whorls with radiating ribs, less conspicuous on lower whorls.

This new species seems to be allied to JZ. zxgucnata Reeve (Conch. Ic. fig. 29) but is much smaller, with, according to figure, much coarser punctures, more convex whorls and it differs also in colour. 13. Mitra albocoronata n. sp. Pl. XXII, fig. 6. Stat. 77.

Colour (in the fresh specimen) dark olive-brown with a yellowish-white band at some distance below the suture and white spots at somewhat irregular intervals, crossing the space between the band and suture (about 10 on last whorl); moreover a few scattered white spots near the base of last whorl. Shell rather smooth, sculptured by spiral rows of punctures in very shallow grooves, about 9 on penultimate whorl, (base conspi- cuously grooved) and very fine growth-striae. Aperture rather narrow, with slightly crenulated peristome, columellar margin with 4 strong plicae, which are white on a brown wall. Interior of aperture bluish. Pie oulato apert. alt -137/5 lat. ?

Two specimens belong to this species; the largest, broken at the aperture and bleached 23 270 is reddish-brown, with the white markings more conspicuous than in the smaller specimen from Stat. 261. The white subsutural spots remind in some degree MV. coronata Lam. Mr. MEtviti who had the kindness to examine the larger specimen, writes about it: “allied in sculpture and markings to pzcta Reeve (Cape of Good Hope) but differing in form. I can hardly consider it a form of varzabilis Rve, though allied. Nor is it MZ. Cookze Hanley with which I have compared it. I do not know MZ. fulgurita Rve, with which it is perhaps comparable”. Under these circum- stances I thought it fit, to describe it as new, as it did not sufficiently agree with any of these species. 14. Mitra simplicissima n. sp. Pl. XVIII, fig. 114, 6. Stat. 137.

Sculpture consisting of rather distant ribs, 16 on penultimate whorl (wanting on last half whorl, after an accident) and a conspicuous spiral rib, at some distance from the suture, with a faint one between it and the suture; below the broad spiral rib runs a groove and lower on the whorls a few spiral striae are visible; towards the base and on the canal the shell is lirate.

Sculpture much less developed, ribs fainter and of the spirals only traces of the large subsutural one are perceptible, base smooth, colour uniformly white. This new species is not allied to anyone I know. Mr. Metvitt whom I consulted, writes: “A little like 7. tensa Melv. (Journ. of Conch. V, p. 285, Pl. 2, fig. 21) which however is from the Antarctic Ocean or reported so. But it is quite distinct’. The texture of the shell is quite that of deep water and polar species, the type, though captured alive, being slightly worn at the upper whorls; the whole shell has a somewhat corneous appearance. 15.

The two specimens from Stat. 306 are small, young, the largest from Stat. 159 may be fullgrown, though the peristome is not yet developed. It is not without some hesitation, that I unite the specimens from the two localities to one species. Those from Stat. 306 have the whorls a little more convex, the sculpture is slightly coarser, one of the specimens is more distinctly streaked with brown. As these differences however are only gradual and even the two small specimens are not quite identical, I do not venture to describe more than one species. The species is allied to JZ. Joricata Reeve, but very much narrower, that species has five columellar plaits, from 47. aegra it differs in sculpture, that species not being granose. 24. Mitra (Cancilla) interlirata Reeve. REEVE.

The specimens vary in size and markings, that from Stat. 34 is less smooth than those from the other localities. As far as I am aware the radula of Strzgatella has not yet been described. It is tridentate and has 64 rows. The median tooth (M) has a broad base, slightly curved in front, strongly so behind, with 5 cusps, which are considerably longer than the base, three of them are long and a shorter one stands on each side; the laterals (1) are comblike; with 14 cusps, of which the 7 proximal ones are longer than the base, the 7 distal ones become gradually shorter. As will be seen by comparing the figures with those of TroscHeL (Gebiss der Schnecken, Vol. II, Pl. 6), the differences with the radulae of typical A/ztrae f.1. fig. 5 and 6 are not overwhelming and even less than between species still belonging to Metra (cfr. WZ. Marzae). 5. Stregatella zebra (Lamarck?) Sowerby. SOWERBY.) Dhes: Conchyls Vols Veep 19} bla 21, hic AAA Ace Stat. 129. Kawio- and Kamboling-islands, Karkaralong-group. Reef. 4 Spec. The specimens perfectly agree with the quoted figures of SowrrsBy’s JZ. zedra Lam., but Lamarck (An. s. vert. Vol. X, p. 332) enumerates zedva as a synonym of MW. paupercula and most authors (Reeve, Tryon) do the same. Hrparco however (Cat. Mol. Test. Filipinas, p. 67) quotes “zebra Lam. (Sowersy, Mitra, fig. 444 and 445)”; as the specimens do not exactly agree with any other figured form, I have recorded them with SowrErsy’s name, though I am not satisfied that the question is settled. 6.

I cannot distinguish this specimen from the subfossil ones from Celebes, nor could I find in the monographs on the genus J/c¢ra, a species with which I could unite it. The shell is white, with a rather broad orange-brown band below the suture, another at the periphery, only partly visible on the upper whorls and a third at the base, occupying also the canal, though less clearly. The spirals of the base and partly the ribs, especially their upper part, are more or less white. 6. Turricula curvilirata Sowerby.

Sowrersy who thought it might be but a variety of JZ. melongena, did not know the habitat; Tryon who says it: “may be nevertheless only a variety’ of JZ. melongena gives as locality “China?”. Mrtvini (Proc. Mal. Soc. Lond. Vol. HI 1898, p. 40) records it from the Andaman-islands and adds: “Quite distinct from JZ. melongena Lam. It is a rare species’’. 7. Turricula tayloriana Sowerby.

Though the only specimen is not quite identical with a typical specimen I received for comparison, by the kindness of Prof. J. Tiere, from the Berlin Museum, the differences are only gradual, and in some parts the resemblance is so great, especially the ventral side is very similar, that I don’t venture to describe a new species and will only point out the differences. The Siboga-specimen is larger, having a total length of 58 mill. instead of 47, it is a dead shell and the five rufous lirae, that adorn the fresh specimen are wanting, however by transmitted light I see traces of them, the concentric ribs, which are conspicuous in the type, are only present in the upper whorls of the specimen under consideration, and are very faint on its last whorl, on the contrary the finer sculpture of intermediate spiral- and growth-striae is more conspicuous in the Siboga-specimen, and has a nearly cancellated appearance; an apparently more important difference may be, that the canal is nearly straight and that the shell is slightly more ventricose, but this may depend on age or sex; in the dorsal view on the quoted plate, the canal is also nearly straight, more so than in the specimen from Sumatra; lastly the aperture has the same grooves, but in the type I see between each two grooves a few lirae, which are much less conspicuous in the Siboga-specimen, however they are present though only as traces; as however the peristome is thicker, I can lay no stress on this difference and think after all, the two specimen must belong to one and the same species. pease iec/eomesp. bl DS tie, 2; Pl> XOX, fig. o.

Sculpture consisting of rounded concentric ribs, 14 in number on penultimate whorl, much fainter on last whorl, where 45 292 they are however still visible below the suture, but disappear at the periphery or a little below it; these ribs are crossed by much less conspicuous spiral lirae, of which 3 on each whorl are more prominent, with numerous unequal, fainter and intermediate spiral striae, which cross the growth-striae and give under the lens a cancellated appearance to the whole shell. Aperture oval, nearly rounded above, with a very obtuse angle; columellar side with a porcellaneous layer of enamel, which is rather thick, but quite appressed on the body-whorl; at its upper part I see a faint rib, too faint to make the upper angle channelled; basal canal rather wide, curved first to the left, then to the right; peristome simple, with very faint crenulations, corres- ponding to the external spirals, smooth within. The whole shell is of a dull white colour externally, the aperture is porcellaneous. Operculum typical, rather dark corneous, with basal nucleus. eNlhes AE, lev, ine eyes, alle, (Gita Caine) 22, lev, 7/7), Mb The radula has a median tooth (M) with 3 short cusps at a squarely oval base, the laterals (1) have a broad base, strongly curved up at the distal extremity, with normally 6 cusps, of which the proximal one is very small, the other ones are subequal; I see however in many rows, small intermediate cusps, which however seem to be abnormal, as is shown by the figure of two opposite laterals of the same row, the left figure having 2 small intermediate cusps. This species has a superficial resemblance with the preceding one, but is quite different by its particulars of sculpture, the spirals not being compressed as in that species, the ribs are more numerous, the canal is much shorter and much more curved, the aperture is smooth, the shell, though fresh, is quite white etc.; the median tooth of the radula is also different, more so than the laterals. I have named it after Prof. Turrre in acknowledgement of his assistance in procuring materials for comparison. O, JQISDS GETTAMIAIUS ©, Sd. lel, XIDK, ie, 2. Sele “iS.

Spiral sculpture consisting of numerous lirae, which are subequal on the upper ex- cavated part of each whorl, and lower on alternating with stronger ones, so that between each 2 stronger lirae, runs a smaller one, in many cases with a very fine one, on one or on both sides; the lower part of last whorl, has nearly regularly 3 thinner lirae between 2 stronger ones; this spiral sculpture is crossed by stronger and finer concentric striae, producing a granular appearance of the whole surface, also on the backside of canal, which is curved first to the left, then to the right side. Aperture oval, sharply angular above, the last whorl being appressed to the penultimate one; canal rather broad, peristome inconspicuously crenulate; interior of aperture smooth.

This species is nearly allied to /. suéangulatus v. Martens (Die beschalten Gastrop. der deutschen Tiefsee-Exp. 1898—1899, p. 102, Pl. 2, fig. 11) and I have repeatedly compared the Siboga specimens with a type, received for comparison from the Berlin-Museum, as many of the differences seem to be only gradual. The new species is not angular, the concentric ribs occupy only the uppermost whorls, the aperture is broader, the canal much more curved. The character which induced me to describe the species as new, is however the different sculpture, which practically consists of alternately stronger and finer lirae, in /. subangulatus the sculpture is more diversified, as between 2 stronger lirae, I see 6 and even 8 thinner ones, while there are by close examination only 3 intermediate ones in the new species; the spiral sculpture is consequently much more regular and less coarse; in the new species the lirae are 47 294 decidedly granular, which is only the case in the upper whorls of swéangulatus, the lirae of the lower whorls being only slightly crenulate. After all it may be possible, that if more specimens of other localities are known, my species will prove to have only varietal rank. 8. Fusus (Afer) Blosvillec Deshayes. DESHAYES. Enc. Meth. Vers.

Shell ovately-fusiform, spire rather long, conical, with convex sides and short slightly recurved canal. Whorls 7 to 8, upper ones rather convex, last one contracted below the suture, which is distinct and irregularly squamate. Sculpture consisting of broad, rounded, concentric ribs, 8 in number on last whorl, and coarser and finer striae, which make the surface slightly crenulate; this sculpture is crossed by spiral lirae, four in number on penultimate whorl, of which the subsutural is the broadest, these lirae are separated by grooves which have the character of intermediate lirae. Colour orange brown on the lirae, dark red-brown in the interstices. Aperture oval, angular above, peristome rather thick, undulated by the lirae, columellar margin concave. Interior of aperture with rib-like lirae at some distance from the peristome, with a tooth at the entrance of canal; columellar margin with a thick layer of enamel, its basal part with 3 plicae, of which the most basal one is double, its left margin ridge-like, leaving an umbilical slit. Canal short, directed to the left. Interior of aperture yellowish, its margin and canal orange, the margin with brown streaks corresponding to the lirae. Please pee late Oo) pmapents dltas5/,, with canal 8"/,, lat. 37/, Mull: This species is allied to the preceding one, but is easily distinguished by its colour, which is just the reverse of ZL. turrztus, the lirae being lighter than the interstices, moreover it differs in many details of shape and sculpture. In arrangement of colour it resembles much Peristernia lauta Reeve, which has the same sculpture and distribution of colours, but is more slender and there is no white on the ribs, else the differences seem to me to be of no great importance, if compared with the only specimen of /awfa in my collection, which is however in no excellent condition. I have named the species after Mr. J. C. Metvitt, who has made a special study of the genus and has assisted me by comparing the doubtful specimens, and pointed at the differences between the new species and P. /auta. 49 SIBOGA-FXPEDITIE XLIX!d. 39 296 4.

The only specimen is a dead shell, which has been agglutinated by a Xexzophora, as may be seen by a fragment of shell affixed at the canal. As Metvirt (I. c.) had his specimens from a depth of 15 fathoms, it is not probable that the Siboga-specimen has lived at so great a depth, but that it has been washed down, before the Xexophora employed it. Originally described as a Frusus, Mertvity located it in the genus Latzrus, in the quoted volume of the Proc. Zool. Soc. Lond. as “the columellar plaits (were) more distinct in. subsequent examples than in the type”. The Siboga-specimen has 2 strong columellar plaits and one fainter one, so’ I had easily recognized its generic position, without knowing its specific name. 7. Latirus polygonus Gmelin. GMELIN. Syst.

Mr. Metvity writes that though originally only known from Maskat, gulf of Oman, it has lately turned up in 2 or 3 places in the eastern tropics. So its occurence at the above Stations is not at all strange. 53 Fam. TURBINELLIDAE. Vasum (Bolten) Link. 1. Vasum turbinellus Linné. LINNE. Syst. Nat. Ed. X, p. 750, N° 466. RuMpPH. Amb.

In colour-pattern, but not in colour it resembles C. gladrata Ads.; these observations are based however, on the rather rude figures of the Thesaurus. The shells are empty, but the described typical specimen is quite fresh, so it may have lived at the recorded depth. 2. Cyllene Szbogae n. sp. Pl. XIX, fig. 7. Stat. 98. 6°9 N., 120°21' E.

One of the specimens of the last named locality is remarkable by its peculiar colour- pattern, consisting of redbrown spiral lines on the lirae, 7 in number on the penultimate whorl, on a pale ground, as the shape and sculpture are however the same as in the other specimens, I think it deserves even no varietal name. The specimens from Stat. 302 (216 M.) are dead shells. The radula has about 63 rows of teeth; the median tooth (M) is broad with a concave anterior margin, with the characteristic lappets on each side; the convex posterior margin, has 3 cusps, of which the median one is the largest; the laterals (1) have 2 strong teeth, of which the distal one is by far the strongest, it is in proportion shorter but thicker than in P. senticosaus as figured by Troscuen (Gebiss der Schnecken, Vol. II, Pl. 8, fig. 1). 3.

The specimen from Stat. 271, a young empty shell, certainly has not lived at that great depth. The specimens vary in the development of the spiral lirae, which are more or less conspicuous, some specimens from Banda f.1. are scarcely angular; one specimen from Stat. 258 has a golden band and a young one from Stat. 313 has 2 brown bands, but is typical in sculpture. The length of the spire is not constant. These differences in shape, colour and sculp- ture, seem to be individual, as specimens from the same locality are connected by intermediate one Phos varians Sow. may have been established on such an aberrant form. 4.

I see no distinct brown band, as described by Apams and figured by Sowrrsy, even not in specimens taken alive, but the shells perfectly agree with a specimen in my collection, formerly named by Mr. E. A. Smiru. I think Tryon is quite wrong in uniting this species to Ph. senticosus. The radula of a specimen from Stat. 248 has the teeth in about 50 rows; the median ones (M) are similar to those of Ph. rvoseatus, but the base is stronger and not so broad, the central of the 3 denticles is stronger; the laterals (1) have the usual 2 cusps, of which the distal one is more slender and longer than in voseatus; the whole radula more resembles that of Ph. cancellatus (= textus) as figured by Troscuet (Gebiss der Schnecken, Vol. II, Pl. 8, fig. 2). 5.

Subsequent whorls, very convex, with deep suture, with 60 lod 397 narrow, rounded ribs, about 12 in number on last whorl, crossed by thin lirae in upper part of whorls and in the basal part of last whorl; the lower part of upper whorls and median part of last one being impressedly striate. These lirae in crossing the ribs, make them nodulous to nearly spinose, slightly crenulate on lower part, and again granose on the base of last whorl] else the interspaces of the ribs are smooth, but for fine growth-striae. Aperture oblong-oval, rather bluntly angular above; peristome not thick, though thickened exteriorly, a little backwards, by a stronger rib, lirate internally, at some distance from the peristome, by about 15 lirae ; columellar margin rounded, smooth, with a conspicuous, oblique basal fold and traces of a second one, a little higher on. Canal shallow, wide, slightly directed to the left. Alt. to, lat. 45/,; apert. alt. (with canal) 5, lat. 2 Mill. This small species is very different from any species I know, but its generic characters agree with those of the known species of Pos; unfortunately the dredging consists of more or less fresh shells, without the soft parts; the specimens vary in the development of the spiral lirae as mentioned above, but in other respects they have all the same specific character.

This radula only moderately agrees with that of 4. mendicarza, which according to TRoscHEL (Gebiss der Schnecken, Vol. II pl. 8, fig. 4), has a tricuspidate, median tooth, with very small cusps in the interstices and on the side, and bicuspidate laterals.

Mr. Metvirt had the kindness to compare them with his typical specimens and is of opinion that though the canal of the larger specimens is more produced, it is identical with JZ. daph- nelloides. Metula andamanica Smith (Ann. and Mag. Nat. Hist. Ser. 7, Vol. XVII, 1906, p. 165) seems to be the nearest ally, the description of the nuclear whorls being very similar. Nassaria Link. 1.

The specimens from Stat. 5 and 60 are young, the other ones are well developed. The 64 311 radula of a male specimen from Stat. 33, has the teeth in 3 longitudinal rows, so the species belongs without doubt to the Rachiglossa, which seemed to be still a little doubtful to some authors. They are placed in about go subsequent rows; the median tooth (M) is rather broad, with a curved base and 5 cusps, of which the median one is somewhat shorter than the lateral ones; the laterals (1) have the buccinoid type, with two strong cusps, of which the distal one, if the radula be expanded, is by far the largest. Kosrtr (l.c. p. 314) writes on the genus: “wenn /7zndsta (= Nassaria) wirklich zu den Rachiglossen gehért’’. The operculum seems to have a terminal nucleus, but serrate margins; with 7 teeth on the left, 8 on the right side; this is not in accordance with the description of Apams, who (l.c. p. 182) says: “Operculum horny, ovately unguiform, the margin entire’. This statement has been translated by Sowersy (l.c. p..85) in latin. Koperr does not mention it. Tryon, (l.c. p. 104) says nothing about the margins. Tryon’s figure of the radula of WV. acuminata (I. c. Pl, 27, fig. 34) differs but little from my figure, but the median tooth is 6-cuspidate, with 2 smaller central cusps, his figure is a copy of that of Troscuen (Archiv fiir Naturgesch. 1868, pl. 3, fig. 4) which I have not at hand. 3.

Marrat (On the varieties of the shells belonging to the genus Nassa, p. 74 N° 1249) considers it to be a variety of dzmaculosa. I think the species is sufficiently characterized by its enormously developed callosity, partly covering the spire, to be provisionally considered as a good species. The Siboga-specimen is bleached and slightly worn, but I have a fresh specimen, formerly identified by Mr. E. A. Smrru, from South-Sumatra (Lampongs), which agrees in every essential respect. I failed to find the original description. 7. Nassa (Arcularia) leptospira A. Adams. Dee AvcwerOceZO0l. SOc. Wond. 1851, p. TOs. REEVE. Conch. Ic. Vol. VIII, Nassa, fig. 84.

TRyoN unites it with JV. glans as a variety, but his description, mentioning “the revolving brown lines’ of 67 : 314 which KiENeErR (i. c.) says nothing, makes it doubtful to me, that Trvon has known the true elegans. The Siboga-specimens very well agree with Kienrr’s description and figure, though in most specimens the spire is. slightly shorter. I] can not make out if RrErEvr’s fig. 10 in his monograph of /Vassa, be this species or JV. faenza as TRYON suggests, as REEVE has given only a back view. However I should incline to think Rereve’s figure may be a large WV. elegans. var. fulgurans n. var. Pl. XIX, fig. 10. Stat. 204.

That from Stat. 204 sufficiently agrees in sculpture of upper whorls with the type, in that from Stat. 279 the riblets are coarser and extend over more whorls, only a little more than 2 whorls remaining ribless. 10.

Shell ovately-conical, with rather long spire, dark flesh-coloured, with irregular brown flames, forming a more or less conspicuous brown spot on the back of last whorl. Whorls 9, of which 3 smooth ones form the nucleus, which has a brown subsutural band and a peripheral keel. Subsequent whorls with strong, rounded ribs, which are at first narrower than the spirally striated interstices, then about equal in breadth, and disappear on the 8'* whorl, the last being quite smooth, but for microscopic growth-striae, very inconspicuous spiral striae and about 5 deep basal striae or grooves; the whorls are rather convex, separated by a deep suture. Aperture broadly oval, slightly canaliculate above, peristome with a blunt border, internally with about 17 irregular lirae, which are not strong, with exception of the basal one, bordering the canal, which is toothlike. Columellar margin with a rather strong layer of enamel, callous at the upper part near the upper canal, a strong, short fold at some distance from the callous margin and a row of small guttules; basal fold thick, nearly toothlike in front.

Of the two specimens only the smallest is adult and has chiefly served for description; the largest, though full-grown, has the aperture not yet developed, its margin being smooth and should locate the species in the Section JVassa s.str., together with WV. mutadzclzs. As the shells are in other respects identical, I think they are best located in A/ectryon. The nearest ally may be JV. elegans, but the crassicostate upper postnuclear whorls are quite different from those of that species. 68 ce S25 11. Massa (Alectryon) elegantula n. sp. Pl.

Shell elongately-ovate, with rather acuminate spire, very smooth and shining, cream- coloured, with two more or less conspicuous reddish-brown bands, more distinct only on the back of last whorl, one of them below the suture, the other at the periphery. Whorls about 9, of which 3'/, form a smooth nucleus, with a peripheral keel, the next whorls are costate, ribs about as large as the interstices, they are crossed on the upper whorls by inconspicuous spiral lirae, which disappear as well as the ribs with age, the 7'* whorl is only ribbed without spirals, on the penultimate whorl these ribs become also obsolete, till on the last whorl only a row of large beads remains, giving a coronated appearance to it; these beads are also traceable on the upper whorls; base of last whorl grooved, moreover very fine growth-striae cross the shell. The whorls are rather convex, separated by a conspicuous, slightly canaliculate suture; aperture elongate, canaliculate above, peristome with a narrow, slightly reflected margin and a broad, flat rib behind it, with about 7 denticles on its basal part, internally with about 16 lirae, of which that bordering the canal, is very strong, nearly toothlike; columellar margin callous, wrinkled in its whole length, with a stronger wrinkle above, ending below in an oblique, strong fold. Canal rather deep, narrow. Interior of aperture faintly brown. Alt. 25, lat. 13; apert. alt. (with canal) 12, lat. 6, Mill. I cannot identify this species with any known one. It has some resemblance with JV. laevigata Marrat (On some proposed new forms of the genus Nassa; p. 2, Pl. 1, fig. 7) but is much more elongated and differs in the particulars of the aperture, that species having f.i. a smooth peristome. It resembles fig. 11 of the same plate (V. Alzcosa Krauss, curious var.) in colour but not in shape. WV. zrda may also be allied, but is quite different in many particulars of the aperture and sculpture. Unfortunately the precise locality of the best specimens is not known; those from Stat. 2 are young, that from Stat. 274 is much smaller and perhaps by some particularity of the bottom, more reddish-brown, but it quite agrees in shape and sculpture. 12.

The fault of REEVE is to give only a dorsal view; as REEVE gives as habitat “Galapagos islands and Panama’’, I sent a specimen to Mr. E. A. Smiru, who found it identical; so Tryon may be right in suggesting that these localities are incorrect. Hipatco (Cat. de los Mol. test. d. 1. islas Filipinas etc.) records it from several Philippine islands, Mrtvirn (Proc. Zool. Soc. Lond. 1901, p. 411) from Bombay.

Sculpture consisting of somewhat 7° - 317 curved ribs, about 22 in number on last whorl, these ribs are narrow, with broader interstices, especially on last whorl; they are crossed and rendered slightly granose by spiral lirae, about 16 in number on last whorl, of which the upper one, bordering the suture is stronger and separated by a groove, thus making the sutures beaded. Aperture oval, with a sinus above ; peristome blunt, with a thick, flat rib externally, this rib is crossed by the spiral lirae, internally the peristome has 5 or 6 denticles, of which the basal one has the appearance of a tooth.

It resembles in many respects JV. collatecta Melvill and WV. munda Sturany, especially the smaller specimens of the latter, but seems to be distinguishable from those’ species, by having a different number of ribs, 22 against 12 or 26; in JV. munda the whorls are strongly gradate.

NV. stiphra Sturany has also more convex whorls but less so than in creéricostata, is more gradate, has a smaller number of stronger ribs and much smaller nuclear whorls; the spiral sculpture is less conspicuous on median part of whorls. Though it is not a very agreable task, to describe so many allied new species, I have endeavoured in vain to combine them with each other or with MV. manda and allies. 1 could make no description fit for them all, unless I would make use of a few unsignificant words. I have, though not without doubt, located them in Alectryon, following Metvitt, who places his WV. collaticza in that subgenus, but on account of their affinity with V. dadylonica Watson, I added the name Aczculima adopted by Watson for the latter species, which group has been considered by Cossmann, to be a subgenus of what he calls the genus Alectryon. 20.

The species is no doubt allied to JV. taenza and wnzcolor, and I think has been often mixed with these species. KUsrer is in doubt if RrEve’s fig. 18 belongs to this species. I should incline to think that Rerve’s fig. 17 (wmzcolorata) agrees better with this species, than with Krener’s B. wuzcolorum, at least KiENER’s figure shows no trace of a canaliculate suture, as Reeve’s fig. 17 does, and Ktener’s description does not mention it, moreover the shell of KieNnEr is much more elongate. I have united those specimens which show a distinct, though not always large channel, without regard to the other, most inconstant characters, as size, colour and number of ribs, which merge insensibly into each other. 23.

Most authors agree in this point, but not respecting its synonymy. I have followed the views of Booc Watson (Challenger report) and some subsequent authors. If one compares the large forms -with few ribs, with the smaller many-ribbed specimens, one should incline to admit more than one species, but inter- mediate specimens make it impossible to trace the limit. The allies are a.o. WV. taenza, canaliculata and szguzjorenses. 25. Nassa (Zeuxis) siguiorensis A. Adams var. EX, ENDAMIS, leroe, ZOO, SOG. ILoincl, WE, jd C77 REEVE. Conch. Ic.

Shell elongately ovate, with long, but not very acuminate spire, whitish, with close, reddish-brown markings, consisting of streaks and network, leaving in many parts only white specks, which are very scarce on the back of last whorl, which is nearly totally brownish in one specimen; only near the peristome the shell is quite whitish, with one brown blotch or bandlike streak at the periphery and another at the base, behind the peristome; just below the suture, a narrow zone is alternately blotched with white and brown. Whorls about 9, of which 3'/, form a smooth, brownish nucleus, with convex whorls and a peripheral keel. Sub- sequent whorls sculptured with rather remote ribs, crossed by spiral striae, of which the uppermost is a slight groove, the subsutural zone beaded; this sculpture disappears on the lower whorls, which are smooth or nearly so, with only microscopic spiral striae and growth-striae; lower whorls slightly convex, with a conspicuous subtabulated suture; last whorl with 5 or 6 grooves at the base and a few very flat, broad ribs behind the peristome; aperture oval, canaliculate above, peristome not thick, with a flat, broad rib externally and 14 lirae in the interior, at some distance from the margin, the basal one is the strongest.

However it is impossible to me to separate them. Tryon thinks that WV. fraudu/enta Marrat (On some proposed new forms in the genus Nassa, p. 8, pl. 1 fig. 24) may be identical, but Marrat’s words: ,Callo columellaris albo maxzmo’ and his opinion that this species is closely allied to WV. g/oéosa, are not in favour of that view, though the back view of the shell, the only figure given by Marrar, has much resemblance. WV. crzérarza Marrat (l.c. p. 12, Pl. 1, fig. 20) has another aperture, without the characteristic basal sinus of the peristome. 39. Nassa (Niotha) granosocostata n. sp. Pl. XX, fig. 5. Stat. 64.

Shell ovately conical, ventricose, with rather short, sharp spire, cream coloured, faintly two-banded with reddish-brown, more conspicuously brown-coloured on the back of last whorl. Whorls about 8'/,, of which 3 form a small nucleus, subsequent whorls moderately convex, separated by a deep suture and nearly tabulated, their sculpture consists of ribs running from one suture to the other, 22 on last whorl, these ribs are crossed by thinner spiral lirae, which in passing the ribs, make them subgranose; upper row of granules very conspicuous, bordering the suture and separated from the rest of whorl by a groove; last whorl very convex above, its basal part strongly granose. Aperture oval, its upper corner with a rather broad canal, formed by the upper part of peristome and the fold on body-whorl. Peristome rather thin, externally with a broad, flat rib, internally with 12 lirae, of which the upper and basal ones are the strongest and border the canals. Columellar margin with a conspicuous but not widely spreading callosity, which is porcellaneous, white, granose on the body-whorl, by the granules of the ribs, with irregular plicae on the lower part, ending in a strong, curved fold; basal canal rather wide, deep and slightly upturned. Interior of aperture white, with a slight brownish hue in its depth. Alt. 16, lat. 8%/,, apert. alt. (with canal) 8, lat. 4*/, Mill. This species belongs to the alliance of WV. /zvescens Phil., but may be distinguished by its sharper, granose sculpture, it is considerably narrower in proportion to its length than that species, the enamel on the body-whorl is less extended, its upper margin being horizontal in NV. livescens and the allied NM. Kzenerz, the basal fold of the columella is more oblique and straighter in the new form than in “ivescens. Mr. Metvitt who had the kindness to compare it in the British Museum, writes about it: “I also compared it with a variety (so labelled) of Zivescens Phil. this being smaller, with shorter spire than the type. Your shell is much like a miniature of this and the mouth is likewise very similar. It will perhaps however bear differen- tiation’. After all it may prove to be only a variety of WV. /zvescens, but as long as no more materials are known, I prefer on account of the differences mentioned above, to keep it separate. 40.

That species has been described as smooth, with a broad flesh-coloured band; even in the worn specimens the spiral striae are easily to be seen and none of the specimens has traces of an uninterrupted band, so I must consider it to be distinct.

This species is of a very simple character and has much puzzled me; indeed I was ir doubt if it ought not to be placed amongst the P/ewrotomzdae, on account of the large sinus and thin peristome; unfortunately the soft parts are wanting or at least not visible in the aperture, and as there was but one specimen, I could not destroy it. If the canal were straight, it could be located in the Section Azzlza. 13. Columbella (Mitrella) stmplex n. sp. Pl. XX, fig. 8. Saline 24a Seon lca aE loresssed. 7O4, M.

Moreover the aperture, though apparently well developed, is quite destitute of teeth or folds. I cannot account for the considerable difference of depth, at which the specimens have been dredged, as one specimen of each locality is in fresh condition, though not containing the soft parts. 16.

Under these circumstances I have left them with doubt to the species of Ductos. They are too bad for description. 20. Columbella (Conidea) flava Bruguiére. BRUGUIERE. Dict. N° 53. KIENER. Coq. Viv.

Shell elongately-oval, with rather acute spire, thick, black brown (if dry greyish, perhaps by the action of alcohol) with white upper whorls and base, a few white spots on the whorls about the periphery and a row of white quadrangular blotches at the upper margin of white base. Whorls about 8, of which nearly 2 smooth ones form the nucleus, subsequent whorls only very slightly convex, separated by a rather conspicuous suture, which is however not very distinct by the spiral grooves, with which the whole shell is encircled; these grooves are rather deep, the subsutural and median one of last whorl however less so, the lirae are granose on 2 or 3 postnuclear whorls, lower on they are only closely punctured, the lirae remaining smooth, but for fine growth striae. Aperture oblong, narrow; peristome thin, with only traces of a varix, internally with very faint, irregular wrinkles; columellar margin straight, smooth above, slightly plicate below by the basal grooves. miteOwmldtasss)., aperts alt. 4s/,4 lat. 1 Mull, This species was very puzzling and it is not without doubt that I have located it in gi 338 the genus Columéella; in colour and partly in sculpture and shape, its nearest ally is no doubt Conus atramentosus Reeve (Conch. Ic. Conus; Suppl. fig. 265), which has been located by Pace (Proc. Mal. Soc. Lond. Vol. V, 1902, p. 56) amongst the Columbellidae, and HipaLco follows him in this opinion, in the catalogue of the mollusca of the Philippines (1904—06, p. 88), placing them in the group of C. dormitor Sow. From C. atramentosus it differs by its much narrower shape, the most elongate of my Philippine specimens having a length of 11'/,, a breadth of 6'/, Mill.; in that species I find the same wrinkles in the interior of aperture, on the contrary, I see no trace of them in my West Indian specimens of Co/. dormztor. If the columella were really plicate, one could think these species were Mitroid, the shape reminding some species of Cylindra, which have however in all my specimens a smooth outer margin and strongly plicate columella, the columellar part is more like that of Dzdaphus. Dati (Rep. dredging “Blake” Vol. II, p. 165) brings Col. dormztor to Mitromorpha and indeed many of the characters enumerated there are applicable to the present species; this would locate it amongst Pleurotomidaec, unless Dauu’s impression “that these shells are related to AZztra rather than Daphnella etc.”’ be right. Unfortunately I cannot detect the soft parts, in order to try to settle the question, by examining the radula. 23. Columbella (Conidea) atramentosa Reeve.

Ze pec: After the description of the former species was ready for the press, I found amongst the species of Conus two specimens of C. atramentosus, which I had provisionally classified with the species of that genus, but ought consequently to be located here. One of them is broad, the other considerably narrower, its length being 8'/,, its breadth 41/, Mill. and so still sufficiently different from the former species, which is more oval. Both specimens are empty, somewhat bleached shells. Fam. MurIcIDAE. Trophon Montfort. 1. Lvophon obtuscliyaius n. sp. Pl: XOXl, fies 1, Ply XXIV, figs 5: Stat Sen 7me soe Ty Ie .2E.

Whorls 6 or 7, of which about 1'/, nuclear ones, form a smooth convex-whorled top; sub- sequent whorls convex, separated by a conspicuous but shallow suture, angular about the middle of upper whorls, obliquely declining from suture till angle, nearly straight below the angle and somewhat narrower at the lower suture. Varices laminar, 12 on last whorl, each on the angle with a hollow spine, which is slightly directed upwards, body-whorl with about 6 obtuse spiral lirae, of which the upper one at the angle unites the spines, the other lirae make the margin of varices undulate, 2 or 3 lirae are visible on the upper whorls. Aperture ovate, with arched, thin peristome, interiorly slightly thickened, smooth, white; columellar margin with a thin, appressed layer of enamel. Canal long, directed towards the right, sculptured by the continuation of the varices. Alt. 34, lat. 14; apert. alt. (with canal) 21, lat. 7 Mill. This species much resembles 7. Goodrichz Forbes, as figured by Sowrrsy (Thes. Conch. Vol. IV, Trophon, Pl. I), but the spire of the new species is higher, the canal is less tortuous, above all the species has been described as smooth, I see in the figures no traces of spiral lirae or undulated varices. Many of the hollow spines are broken in the largest specimen, that has served for description and in that specimen the nuclear whorls are wanting. One of the specimens from Stat. 271, has a more oblong shape and the lirae have disappeared, as however the 2 accompanying specimens, though young, agree with those from other localities, I think these differences will be only individual, the wanting of lirae will probably be due to the state of erosion of this specimen, which contains however the soft parts. The radula has a median tooth (M) with broad base of which the anterior margin is convex in the centre and at the sides, the posterior one has sharp angles; of the five denticles the distal ones are larger than the median cusp, with a small intermediate denticle on each side; the laterals (1) have a rather narrow base and a slender cusp, a little curved at the point. Number of rows a little more than 100. 2. Trophon pulchellus n. sp. Pl. XXI, fig. 2. Stat. 159. 0°59.1S., 129°48.8 E. Halmahera Sea. 411 M. Coarse sand. 7 Spec. Shell fusiform, thin, white, with moderately long spire. Whorls 7, of which about 1'/, convex, smooth ones form the nucleus. Subsequent whorls convex, angled above the middle, convexly declining above the angle, contracted towards the deep suture. Sculpture consisting of fine laminate varices, 14—16 on last whorl; these are simple above the angle, where they form free laminae; at the angle they form open spines, which are directed outwards and are slightly upturned, below the angle are 2 rather obtuse lirae on the upper whorls, 5 or 6 on last whorl; in being crossed the laminae bear short spines, decreasing to scales near the base of last whorl. Canal moderately long, with nearly straight lamellae, corresponding to those of last whorl. Aperture triangularly rounded, upper margin convex, outer margin slightly thickened at some distance from the thin rim; columellar margin enamelled, appressed; canal open. Alt. 151/,, lat.

This species is nearly allied to 7. plicelaminatus Verco (Trans. Roy. Soc. South Austral., Vol. 33, 1909; p. 335, PI. 24, fig. 1, 2) so much, that I thought it might be identical, but Mr. Smirn who seems to have compared it with a cotype, says it is different. The Siboga- specimens are larger, have a whorl less, a specimen of about the same size as plzczlaminatus has but 6 whorls; the new species is broader in proportion to its length, has as least one lira more and the figure of VEeRco has only one row of spines, in the new species 3 of 4 lirae may be called spinous. In that species the canal is longer. Tvrophon segmentatus Verco (il, &: fig. 3) has a shorter canal, a larger number of lirae, but agrees in the more spinelike character of lower scales. 3.

Some of the specimens are very young and consequently more a less doubtful, however by comparison with the well developed upper whorls of adult specimens from the same localities, I think the identification is right. Cabinet specimens are often too much cleaned to allow a close comparison. As far as I can judge from one specimen of MW. ¢trzéulus, from the Red sea, TRYON was wrong in uniting them, as the postnuclear whorls in JZ. trzdulus are scaly, against rounded ribs in JZ. nigrispinosus, as has been more elaborately explained by Boog Watson in his Challenger Report. The radula of a female of this species, much resembles that of A/. ¢rzdulus, as figured by TroscHEL, as far as concerns the shape ,of the basal plate of the median tooth (M), which is slightly convex in the centre of the anterior margin, with prominent angles, the central denticle as well as the lateral ones, which latter are slightly curved outwards, are longer, with an apparently longer small cusp between them, on each side of central denticle; the 94 341 laterals (1) are hooked with a broad base, but less so than in the next species, with a rather long, sharp point.

As the type of this species I have united those specimens, which agree with such ones named some years ago by Mr. E. A. Sirs, though not quite agreeing in structure of the upper postnuclear whorls, a few having them more squamous than the majority, which has them more rounded. The deepwater specimen from Stat. 262 is an empty shell. If after all the specimens prove to belong to 2 species, perhaps the plates of the projected work on Lamarcx’s shells, will settle the question, which of both forms is the true ¢ernuzspzna, they agree in pos- sessing long, slender spines. E. A. SmirnH (Ann. and Mag. Nat. Hist. Ser. 7, Vol. XIII, p. 461, 462) has made also observations on differences of sculpture “of the first three normal whorls’’. The radula of a female specimen from Stat. 51 has a median tooth (M) with a concave anterior margin and prominent rounded angles at each side, with 3 large cusps at the posterior margin, of which the lateral cusps are a little curved outwards, and much smaller intermediate cusps. The laterals (1) have a broad base and terminate in a sharp point. var. rufolirata n. var.

Though the canal appears to be not complete, the specimen has a total length of nearly 140 Mill., of which 70 Mill. come for the length from the apex to the base of apertural varix, this is nearly in accordance with my Japanese specimen of 160 Mill., which may consequently have been about the length of the Siboga specimen, if complete.

The quoted authors did not know the locality of this form. I have quoted SoweErsy’s description with a note of interrogation, as he says that the rufous lines run at the top of the lirae and though the figures of the other authors seem to have the same arrangement, they do not mention the fact. The Siboga-specimens, which have been verified by Mr. E. A. Suiru on account of this circumstance, have the dark lines on the narrow intermediate lirae, between the principal ones. According to this authority it is a variety of JZ. aduncospinosus. The radula of a female specimen of this variety has about 165 rows of teeth, which do not differ much from those of the allied species described above, the denticles of the median tooth (M) are moderately long and rather thick, resembling in this respect those of MZ. ¢enuzspina, the laterals (1) are not much curved. 6.

This long tail had misled me in identifying it, I owe the identification to Mr. Smiru; the other specimens. are young. Perhaps the other known specimens had this tail broken, for in this condition it better agrees with the quoted figures. A young specimen from Stat. 162 perhaps belongs to this species. 8.

This species of which I know no good figure, has often been considered to be a variety of the preceding one; it differs in shape, sculpture and colour, as far as I can judge from my specimens from the Philippines, Amboina and Mauritius; how this may be, the Siboga specimen, though a dead shell, belongs to the elongate form, with deeper sutures, sharper ribs between the varices and mottled brown colour-pattern on a yellowish ground, without the rosy tints of the preceding species. 12.

This species has much puzzled me, it resembles JZ. adustus, Bankszt and allies, but is not identical. Mr. Suir has named it for me, but though I find the name mentioned in the monographs of SowerBy and Tryon, I find no reference, where it has been originally described. SowErBy declares it to be a synonym of despectus, which according to SmiTH is the same as M. adustus (Ann. and Mag. Nat. Hist. Ser. IV, Vol. XV, 1875, p. 419), TRyon says it is the young state of JZ. adustus; it is different by its fronds, the plicae between the varices and the smaller aperture, which is darked coloured. 15.

The specimen is rather doubtful, it is small, probably not adult, darker than any of the quoted figures, has the nearest resemblance with Sowxrsy’s fig. 45; the fronds are decidedly shorter than in J/.

The basal part of the median tooth (M) of the radula has an anterior margin which is protracted in the centre and at the sides, the posterior angles are sharp and toothlike, its free posterior margin has the common 3 denticles, of which the lateral ones are the longest, the central one is short and thick, with a small cusp at each side. The laterals (1) are strongly hooked, with a long slender cusp ending in a curved point, these laterals being relatively much less bulky than in the 77z6uZus-section. The specimen was a female. 17.

Whorls about 7 or 8, (in the finest specimen the upper whorls are incrustated, in the other one worn) convex, slightly flattened above, separated by a deep suture. Shell rather smooth, with 8 varices on the upper whorls. 6 on the last; these varices have 2 hollow spines on the upper whorls, 3 on the penultimate and 6 on the last one, the upper spine of each varix is the longest and elegantly turned up, the other ones are only slightly upturned, the spines are connected on the intermediate areas by rather inconspicuous spiral ribs or lirae. Aperture subtriangular, upper margin horizontal, outer margin convexly curved, the spines not very prominent, as in the apertural varix they are connected by a very fine wall, consisting on the front side of fine angular scales, which are moreover undulate. Interior margin with 4 tubercles; columellar margin smooth, with a thin free lamina, columellar side and outer border of upper and right margins light violet, interior of aperture brown; canal moderately long, a little open, directed towards the right and upturned, with an external row of scales at its origin, formed by the ends of the varices. Alt. 15, lat. 8 (inch peristome but without spines of opposite varix) apert. alt. (with canal) 81/, lat. (from columellar margin to internal outer margin) 2 Mill. This fine species is, according to Mr. Smirn, similar to JZ. purztus Hinds, but is not so much contracted below and the upper spines are much less curved, moreover that species is from the West-coast of N.-America; it has in my opinion more resemblance with JZ. Hidalgo Crosse, which is however much larger (36 Mill.), of another colour and from the West Indies. 2. Ocinebra fuscofrondosa n. sp. Pl. XXI, fig. 4. Stat. 50. Bay of Badjo, West coast of Flores.

Apex wanting, remaining whorls 41/,, very convex, obliquely flattened above, with deep sutures, 103 35° each whorl with 6 varices, which are shortly frondose, the largest fronds at the shoulder; below this frond there are 4 principal fronds, with smaller intermediate ones and 3 small ones between shoulder and suture, lastly 3 on the canal, the fronds of each varix are connected with those of the next one by spiral lirae, according in strength with the size of the fronds, giving a spirally lirate and striated appearance to the shell. Aperture subtriangularly rounded, apertural margin fringed, internally lirate, columellar side with a lamina, which is loosened at its free margin. Canal nearly closed, slightly directed towards the left. Alt. 14, lat. 8; apert. alt. (with canal) 7, lat. 3 Mull. I know no species of Ocznebra to which this species is allied. It has somewhat the appearance of a miniature of JZ. (Phyllonotus) Stainfortht, but the convex whorls and still more the deep suture, exclude the idea that it should be the young of it. 3.

Siuzthz was not quite developed). After all I should not be surprized if with more materials the 2 forms must be united. Maculotriton Dall. 1. Maculotriton digitalis Reeve. REEVE. Proc. Zool. Soc.

This species: seems to be rather variable, the specimen from Stat. 204 agrees with Reeve’s figure of his Pyraula (Rhizochilus) Deburghiae (\.c.) as far as concerns the development of the fronds, but the sculpture of the body is more crowded, the number of spiral lirae seems to be larger in the Siboga-specimen; in this respect the specimens from Stat. 289 better agree, the fronds of 2 specimens are however more developed and more erect, remembering the figures of Dati, (Blake-report, Bull of the Mus. Comp. Zoology, Vol. XVIII, p. 218, Pl. 16, fig. 5); these fronds being also more serrated than in Reeve’s figure. The latter specimens have also a tendency to be more or less costate, as seems to be the case with Sowrrsy’s L. carzniferus (Thes. Conch. fig. 6); on account of these differences it seems questionable if that species can stand as specifically different from ZL. Dedurghiae. The aperture of at least one specimen from Stat. UMAYe iheONaN specimens. 289 is tinged with pale violet, which is probably the case in every fresh specimen ; Stat. 47 is very young, but sufficiently agrees with the upper whorls of larger IIl2 2. Lateaxts Sidogae n. sp. Pl. XXI, fig. 8. Stat. 89. Pulu Kaniungan ketjil. Reef. 1 Spec. Shell elongately-biconical, white. Whorls about 7, of which the upper one forms a rather smooth but not quite intact nucleus; subsequent whorls angular, obliquely flattened above, contracted towards the deep lower suture. Sculpture consisting of 4 strong spiral lirae on body-whorl and numerous intermediate ones; the strong lirae are spinous, the upper one has long, slender, hollow spines, which are turned up, on the upper whorls is a second row of shorter spines, on last whorl there are five rows at all, of which the third is less conspicuous, one or two rows on the canal are likewise more prominent, moreover the whole shell is covered with lamellae, which in crossing the lirae are squamous, as well on the stronger as on the intermediate lirae. Aperture triangularly rounded, upper margin short, outer one slightly convex, internally with 4 grooves, corresponding to the strong lirae; columellar margin strongly enamellous, canal rather broad, tortuous, with a free lamella and an umbilical slit behind it, bordered by a row of larger scales. Alt. 17, lat. (without spines) about 71/,, (with spines 14); apert. alt. (with canal) 8, lat. 3 Mill. This species belongs to the group of Z. dzadema Adams and seems, according to the figure, to be the nearest ally of ZL. exfoliatus Sow. (Thes. Conch. Vol. V, Latiaxis, p. 3, Pl. 1, fig. 15), it is however considerably less convex, the aperture is consequently narrower, the spines are more slender, straighter, more spreading; it agrees by being nearly without umbilicus. 3.

Whorls 6'/,, of which 11/, form a smooth nucleus, followed by a short bilirate space; subsequent whorls angular, with a row of spines growing gradually larger, 7 on last whorl; these spines are slender, spreading, slightly upturned, hollow, rose coloured in their interior; the upper part of whorls is nearly horizontal, but a little declining, with narrow lirae, occupying also the upper surface of spines and partly squamous, lower part of last whorl with 4 conspicuous lirae, interrupted by varices below each spine; these varices form short spines or scales, about 2 on each crossing- point; moreover fine intermediate lirae and slightly squamous growth-striae give a scabrous appearance to the shell. Aperture elongately-triangular, upper margin nearly horizontal, outer one thin, undulated by the lirae, slightly convex, interiorly of a beautiful rose-colour, with a few grooves, corresponding to the lirae, columellar margin appressed above, free below, at the narrow but conspicuous umbilicus, which is bordered externally by a row of coarse, rosy scales; canal short, wide. Alt. 14, lat. (without spines) 81/,, (with spines 19); apert. alt. (with canal) 8'/,, lat. 31/, Mill.

Aperture rounded-triangular, upper margin slightly convex, outer one more so, with a groove corresponding to the erect wall at the union of both margins, columellar margin enamelled, appressed, becoming a free lamella at the rather narrow, tortuous canal, on the left side of this lamella an umbilical perforation, bordered by a rounded, squamous, curved, basal varix.

Sand, coral and mud. 12 Spec. It is not without some doubt that I have named the specimens C. ferszca, as I had first sent a few of them to Mr. Metvitt as the author of the species, who did not recognize them, but afterwards I learned his 2 specimens were sent to the British Museum; as it is not safe to describe new species in this genus of variable forms, without close comparison with the types, I consulted Mr. E. A. Smira, who says about this shell: “the nearest species we have 116 363 is C. persica Melvill and indeed I do not think they are separable. We have two specimens of C. ferseca and both have the upper part of the spire not quite so pointed as in your shells, otherwise I can find no difference’. As the nuclear whorls are so often more or less eroded, this difference may be of no great importance. Other differences I found with the quoted figure are that part of the Siboga-specimens are considerably larger (till 21 Mill. in length, instead of 15) that the last whorl is often much more ventricose, the canal commonly more slender and not so straight; as however many of these characters are slightly variable in the Siboga specimens, I think it will be fit to accept Mr. Smirn’s views, as he was the only person, able to make direct comparison. The species has also some resemblance with C. Feffreyst, but Mr. Smirn says it is quite unlike and even a less typical specimen, with more equal lirae, sent by Mr. Metvitr for comparison, is very different in its particulars of sculpture. nny ei ed .

J. BRILL PUBLISHERS AND PRINTERS : EYDEN — 1913 BART Vv TOXOGLOSSA WERE “Aves UP Py Bs VE NV The very interesting section of the Toxoglossa contains 228 species, of which no less than 65 appear to be new to science, moreover to this part a small supplement to preceding parts has been added, containing 3 new species. The family of the Pleurotomzdae, with 127 enumerated species and a few varieties, has given me much trouble, but has not given me full satisfaction, the systematic position of many species remaining still more or less doubtful and the classification of this family much wants a revision. I have often followed the arrangement of the late Prof. BorrrcEer for the species from the Philippines. The relatively small number of specimens dredged with the soft parts, prevented me from examining the radular teeth, in most cases where they might have given some light. Under these circumstances, I am very grateful to those persons who have assisted me in the identification of critical specimens. Mr. E. A. Smirnu I.S.O. often compared them with the treasures of the British Museum, Mr. J. Cosmo Metvitt has given me his advice and in some cases specimens for comparison, Mr. J. R. te Bocktron Tomttn likewise assisted me by identi- fication or loan of specimens, Mr. J. J. VeRwyNEN has again much obliged me by the loan of books from the rich library of Teyler’s Museum, and other persons amongst which I wish to name Dr. R. Horst, have assisted me in several ways. I beg them all to accept my kind thanks. In two cases I was compelled to erect new genera of Plewrotomzidae, as it was impossible to locate the species in the existing ones, though I was not at all eager to enlarge the number of groups, as long as no revision of the whole family has been undertaken by some person who is in particularly favorable conditions, to fulfil this much needed but very trouble- some task.

Upper whorls wanting, remaining whorls 7, but may have been nearly the double, if one considers the subulate shape; whorls nearly straight, only slightly convex, separated by a deep suture, with slightly curved ribs, 18 on last whorl, divided at the upper part by a groove, consisting of a row of conspicuous punctures between the ribs, but scarcely affecting the ribs themselves and with 4 impressed spiral striae on each whorl, conspicuous between the ribs and at their sides, but very weak on their crests; about 12 spiral striae on last whorl, of which 8 crossed by the ribs, the interstices of the basal ones having more the character of granular lirae, are not ribbed. Aperture elongate, angular above, with a sinus formed by the body whorl and infrasutural belt; right margin obtuse, columellar side with a strong layer of enamel, its interior margin with two folds, canal short, divided by an oblique rib, closely striated above and below it.

Whorls 25, of which about 3 form a smooth nucleus, with convex whorls, subsequent whorls strongly convex for the genus, separated by a deeply impressed, undulated suture; sculpture consisting of conspicuous, elegantly curved ribs, 14 on last whorl, the crests of ribs smooth, but their sides and the interstices 7 32 crossed by numerous impressed striae, or if one considers their interstices by unequal flat lirae, 18 striae on penultimate whorl, of which one, placed at some distance from the suture, has the appearance of a groove; the ribs nearly reach the base of last whorl, where the number of striae is much more considerable; this last whorl is very long, subangularly rounded below, then strongly contracted. Aperture elongate, narrow, with a not very sharp angle above, ending in a rather long, curved canal below; peristome not intact, columellar margin consisting of an appressed layer of enamel, with a scarcely appreciable groove below, bordering a faint columellar fold.

Fortunez 69 Mill.) there are but 6 spiral striae, of which the first borders the subsutural zone, in the new species this zone is likewise striated, and though the specimen from Stat. 204 has only 12 spiral striae, this number is still twice the number recorded by Dersnaves for 7.

The Siboga-specimen is very light-coloured, nearly quite white, with 4 brown grooves on last whorl, instead of the three, figured by the quoted monographers; as I possess a specimen from the Andaman-isles, with even 6 grooves, of which 5 are brown, but which is otherwise typical, I think it is unnecessary to apply a varietal name, unless one would call them 3—4—6-swlcata and so on. The specimen scarcely seems to be bleached; the fourth groove of the Siboga- specimen is placed below the periphery, so that it is covered on the upper whorls. In the P 2 periphery PP Andaman-specimen the colourless groove is placed between the two brown grooves, corresponding to those of the quoted figures, one has the same position as in the Siboga-specimen and the basal one in double, making 3 additional grooves. ats Terebra (Strioterebrum) triseriata Gray.

Reeve and Tryon consider this species to be only a synonym of 7. fuxzculata Hinds; as far as I can judge after one specimen of each, Avchzmedes has the subsutural lira less prominent, the number of lirae of each whorl is less, the lirae are more granular, the last whorl is considerably shorter, moreover the colour is much lighter. As this species seems to be unfigured, I have given a figure. 34. Lerebra (Strioterebrum) virgo n. sp. Pl. XXV, fig. 13. Stat. 50. Bay of Badjo, West coast of Flores. Up to 40 M. Mud, sand and shells. 1 Spec. Shell elongately turreted, shining, white, upper postnuclear whorls cream-coloured. Whorls 14'/,, of which 21/, form a large, mamillate, smooth nucleus; .postnuclear whorls at first rather straight, the last 8 concave; sculpture consisting on lower whorls of a conspicuous, crenulated, subsutural rib, accompanied by a narrower second one, separated by a strong groove, this second rib being likewise crenulated or beaded, concave part of whorls crossed by flat axial ribs and with remote spiral grooves, 3 in number, so that this concave part is 4-lirate, of these lirae the upper 2 are the largest. At all the lower whorls have 6 lirae, inclusive of the subsutural one. Last whorl short, with a larger lira below its angle, separated from upper part by a stronger groove and with some narrower lirae on the base. Aperture subquadrate, with a short, sharp sinus above, a short wide canal below; peristome blunt; columellar margin short, faintly bicostate, with an appressed layer of enamel. Alt. 25, lat. 5%/,; apert. alt. 5 (with ‘canal), lat. 27/, Mill. This shell is quite different from the preceding one, by its more or less concave whorls, it is much less acicular than Archemedes, which it slightly resembles in some respects; the 12 SH Ai whorls are much broader, consequently much less in number, 7. Archimedes of the same lenght would have 24 whorls; the bulbous nucleus may also serve as a good distinctive character. Hastula Adams. 1. Hastula (Hastula) matheroniana Deshayes. DESHAYES. Proc.

Reeve considered this species at first as a synonym of 7. strzgzdlata, but afterwards in the ,corrigenda’’ separates it. Tryon remained in doubt, but finally refers it to str¢g7llata. Unfortunately the only specimen is not in sufficient condition for a figure, as not only the shell has two holes, but the aperture is severely damaged. I think it is sufficiently distinct by its size, acicular shape, sharper ribs and colour. 2. Hastula (Impages) coerulescens Lamarck. ANMARCK Ane Sy vert. Eid. Ty Vol. X, p. 245.

Fam. CONIDAE. Conus Linné. After having made some trials to arrange the species of this genus in the known sub- genera and sections, I find that authors are not at all agreeing in this respect, so much so that even one and the same species has been located in different sections, by the same author, in subsequent papers; under these circumstances I have followed Tryon, his monograph being the latest, which enumerates the species in a systematic order; his method, based on the views of WetnKAuFrr, brings the species to natural groups; I have only made a few exceptions. 1.

Though Tryon may be right in uniting this species with C. Zteratus Lin., it differs not only as he says (I. c.) by the spots being smaller and much more numerous and by the absence of the yellow bands, but the character by which I could separate the very numerous specimens I have seen, is that, mentioned by Kirner, that the whorls are spirally striate on the spire, which is not the case with C. “teratuws, where they are smooth. 3.

In shape it resembles the broader specimens of C. ammdralis, but in colourmarkings I know no species in that or in allied groups, which could be compared with it. The number of whorls which may have been 10 to 12 and the different sculpture of the lower whorls, may justify the opinion, that the specimen is adult or nearly so. 23.

Reeve (l.c.) says: “varying remarkably in their general appearance; most of them are obsoletely coronated, and all have the grooves more or less developed’.

Whorls 8, of which about 3'/, (upper one not intact) form a quite smooth, convexly-whorled nucleus, subsequent whorls angular, first with 3, lower on with 2 spiral grooves, slightly coronated in upper post-nuclear whorls, the grooves on lower whorls punctured, space between the deep suture and upper groove, with perpendicular remote riblets, that between lower groove and suture, with very oblique striae, infra-angular part of last worl in its upper part scarcely grooved, but with a few spiral rows of punctures, 28 393 transformed in distinctly punctured grooves towards the median and on the basal part, 28 at all; last whorl contracted towards the base, its outline being concave. The brown colour on the last whorl, forms median and basal interrupted bands, on the spire it is arranged in regular blotches. Aperture narrow, angular above. Alt. 18'/,, lat. 6 Mill. Though the specimen is evidently young and allied to the preceding species, I could not unite it, as the particulars of sculpture of the considerably lower spire differ too much from that of C. aculezformzs, the whorls being much more prominent at the suture, with quite different sculpture, the shell is much less grooved and more shining, the colour, though perhaps a little faded, seems to be much lighter. I had sent it to Mr. E. A. Smiru, who did not find it identical with any form of C. aculezformis. 48. Conus (Asperi) elegans n. sp. Pl. XXV, fig. 4. Stat. 153. 0°3.8N., 130°24'.3 E.

The nuclear whorls, about 4 in number, are at first smooth, then over a larger or smaller part costulate, with more or less conspicuous traces of a narrow, undulated keel, just above the sutures (this nucleus remembers the section Gemzmula). The specimens vary slightly in colour, some of them being lighter, I think only in part by being bleached. 10. Pleurotoma (Hemipleurotoma) violacea Hinds.

The specimen is small, about 6 Mill.; it probably would be broader, even than Smiru’s fig. 6, if adult; the species has been considered by many authors as synonymous with or as a variety of P. vzolacea Hinds, the Siboga-specimen, which has been identified by its author, seems to differ sufficiently from young specimens of wzolacea, being much less slender, even though it appears to be slightly variable in this respect. The sculpture appears also to differ con- siderably, but the only specimen is too small, to be fit for close comparison. 12. Pleurotoma (Hemipleurotoma) sp. Stat. 260.

Mr. SmituH, whom I wrote about the question, persists in his opinion, that the two forms are separable and that the true gemmata is Californian. May it be that P. gemmata of many authors is not the same as that of Hinps? Some very young specimens are of course rather doubtful. 14. Pleurotoma (Gemmula) monilifera Pease. PEASE. Proc. Zool. Soc.

Shell shortly fusiform, very thin, whitish under a yellowish epidermis. Upper whorls wanting by erosion, remaining whorls 5, angularly convex, separated by a conspicuous undulated suture; upper part of whorls concave, lower part slightly convex, sculpture consisting of strongly waved ribs, more conspicuous in upper whorls, becoming fainter in last one, where they nearly disappear and have more the character of strong growth-lines below the periphery; on the upper whorls these ribs form tubercles on the fasciole, becoming more foldlike on the lower ones; the whorls are crossed by numerous spirals, forming a subsutural rib, which on upper whorls is more conspicuous and adorned with small beads, corresponding to the upper ends ot the ribs, the excavation and fasciole are finely lirate; on the basal half of each whorl, the lirae are coarser, especially on last whorl, where they are irregular, with some intermediate ones. Last whorl strongly contracted below periphery, ending in a short, wide canal, slightly directed to the left. Aperture oval, with a moderately sharp angle above and a very wide but not deep sinus at the periphery; peristome thin; columellar margin with a conspicuous white layer of enamel.

Though the species may belong to the alliance of P. fraeseguzs Smith and rotatilis v. Marts., it is impossible to combine it with any of the described species. 19. Pleurotoma (Gemmula) Srbogae n. sp. Pl. XXVI, fig. 2. Stat. 137. Channel between Makjan and Halmahera. 472 M. Fine dark muddy sand. 1 Spec. Shell broadly fusiform, with acute, conical spire and strong, angular last whorl, thin, whitish, faintly yellowish on the keel, between the nodules. Whorls 11, but the number may be considerably more, as the upper nuclear whorl seems to be wanting and the shell has the appearance of being not adult. One upper nuclear whorl (or 2) smooth, convex, followed by nearly another whorl, with rather remote ribs; subsequent whorls concave above the keel, with a moderately strong infrasutural keel and 1 or 2 other spirals in the excavation between suture and kecl; the infrasutural keel becomes fainter and is scarcely if at all traceable on lower whorls, where on the contrary the number’ of spirals increases, so that on last whorl of the specimen their number amounts to 6 and two very narrow ones just above the keel; this latter is rather narrow, composed of 3 narrow superficial spirals 40 more conspicuous between the nodules, ’ 405 perhaps rubbed off on the nodules themselves. Below the keel the last whorl is very convex, but soon contracted and passes into a slender, moderately long canal; the whole lower part of this whorl is lirate, irregularly on body, where 2 lirae are stronger, more regularly on canal; total number of these lirae about 35, but on base of tail too faint to be properly counted; moreover a few narrow intermediate ones below periphery, and the whole shell exhibits very fine growth- striae. The nodules on the keel are rounded, slightly compressed, not very numerous, 24 on last whorl. Aperture triangular with an angle above and at the keel; interior of aperture white, smooth, columellar side enamelled, peristome thin, broken. Alt. 27%/,, lat. 11/,; apert. alt. with canal 14°/,, lat. 41/, Mill. It is not without some hesitation that I describe this new species on a probably incom- plete specimen, but as the number of species in the section to which it belongs is not over- whelming, I think it may afterwards be recognizable if adult specimens are captured. Its nearest ally may be PP. carzmata Gray, as ‘defined by Smirn (Ann. and Mag. Nat. Hist., Ser. 6, Vol. XVIII, 1896, p. 368), which should be the same as P. sfeczosa of REEVE, WEINKAUFF and Tryon. It differs by the large number of spirals, of which there are but from 1 to 3 in Gray’s figure, on Plate 23 of his “Mollusca” in the “Animal Kingdom’, Vol. XII, though the peristome of that figure seems to indicate a larger number of lirae. In Reeve’s figure (Conch. Ic. fig. 9) the number of keels is likewise much smaller, on the contrary the nodules of keel are much more numerous than in the new species, the same is the case with WertnKaurr’s figures (Jahrb.

The Siboga-specimen contains the soft parts, however in too much contracted state, to say much about them.

This species belongs to the section Lrachytoma, often written Brachystoma, the first orthography being employed by Tryon on page 155, the second on page 176 of his Manual; Borrrcrr (Nachrichtsbl. d. D. Mal. Gesellsch. 1895, p. 6) says Brachystoma, CossMANN (Essai de Paléoconchologie, part Il, pag. 62) Brachytoma non Brachystoma. A worse evil is that the limits of the sections are so ill-defined, that no two authors agree in referring the species to one section or to another, under such circumstances I thought it better not to quote them at all. 2.

The only specimen is a young, empty shell, and without Mr. Smirn’s assertion, I should not have recognized it as belonging to that species. It is reddish brown, with white upper whorls, light coloured near the base and on the ribs, but I can trace no dark zone, as figured by Reeve. It is too incomplete (young) to give it a varietal name, length only 21 Mill., moreover it is possible that it might have been more typical if adult. It have not quoted the figures of WernkaurFr or Tryon, that of Tryon being a copy of Reeve’s figure, WetnKaurr’s figure agreeing no more with the Siboga-shell; both authors consider this species to be a synonym of D. flavidula. 5.

Mr. SmirH who compared it for me, says it is allied to but different from axgusta SmirH (Ann. Mag. Nat. Hist. Ser. 4, Vol. XIX, 1877, p. 495); that species is still narrower, has a considerably larger number of ribs on last whorl (15) and has 5 or 6 spiral grooves on upper whorls, with 5 or 6 nodules on ribs, (only 2 or 3 in the new species). 8.

Whorls 6, (apex broken; the number of whorls may have been at least 10) rather convex, slightly excavated below the conspicuous suture, which is accom- panied by an inconspicuous infrasutural thread. Sculpture consisting of somewhat oblique ribs, nearly crossing the entire whorl in the upper ones, but becoming obsolete in the infrasutural depression of lower whorls, about 15 ribs on last whorl, of which the ventral ones are obsolete, that behind the peristome very strong, varix-like, moreover the shell is covered with fine growth-striae and very fine spiral striae, only visible under a lens, 6 spiral lirae cross the ribs, in most cases with intermediate, much finer lirae and 3 to 4 very faint ones in the excavation ; 44 409 b) on the last whorl the number of principal lirae amounts to 20. Aperture oblong, narrow, with thin peristome, protracted about the middle, with a deep, rather wide sinus above (fig. 1,) columellar side with a thick layer of enamel, with a flat, whitish tubercle above at the sinus, straight below, peristome margined with red-brown interiorly, with a light violet layer of enamel behind, in the depth again red-brown, upper part of columellar layer red- brown.

Though this only specimen is incomplete, it seems to deserve description. It has some superficial resemblance with Pleurotoma (Drillia) castanea ReEvE, by its shape and colour, but it differs in sculpture, is less angular, D. castanea being according to description smooth, with fine grooves at the base, WEINKAUFr’s description and figure of that species (Conch. Cab. Pleurotoma, p. 102, Pl. 22, fig. 46) scarcely agree with those of Reeve, as his shell is “spiraliter liratula’’ ’ Fig. 1. which should better agree with the Siboga-specimen. I can scarcely believe that Dritlia rubido- Susca D. sp. the differences could depend on age, as WeINKAurF suggests, at least the upper whorls in my specimen are likewise lirate, WrrInKAuFr’s figure represents a much broader angular shell, more strombiform. 11.

Whorls about 11, of which about 11/, form a smooth, inflated, laterally-inclined nucleus. Postnuclear whorls angular, very convex, separated by a linear, undulated suture, accompanied by a faint infrasutural rib, more conspicuous on upper whorls; upper part of whorls conspicuously exca- vated, lower part with strong, short, nodulous, oblique ribs, abruptly ending at the excavation, scarcely reaching the basal -suture in lower whorls. There are 3 faint, raised, spiral lirae in the excavation, crossed by elegantly curved, partly riblike striae, 4 to 5 stronger lirae crossing the ribs, with a few faint striae above them on the limit between ribs and excavation in lower whorls; on the penultimate whorl, another liration appears at some distance above the suture, amounting to 3 rather remote, strong lirae on last whorl, and a large number (about 20) on basal part of last whorl and canal; body-whorl strongly attenuated below, ending in a long, slightly curved canal. Aperture ovate, probably with a rather wide, deep sinus (the peristome is broken), columellar margin concave above, strongly contorted below, with a thin layer of enamel. Mites /paldteno wapegtralt 12/5 lat. about 3'/, Mull: The specimen from Stat. 159 has the lirae in the excavation somewhat more apparent, which may be due to its being a dead, calcified shell; one of the specimens from Stat. 256 is _ young and very bad, that which has served for description, though incomplete, seemed to be remarkable enough to deserve a name, for though broken, it is a rather fresh shell, the great 45 410 depth may be the true one, as the depth of the two localities does not differ considerably. This species is remarkable for its pagodaeform shape, caused by the great contrast between the upper and lower part of whorls. 12. Drillia varicosa Reeve.

The quoted figures are not very satisfactory, still less so the synonymy given by Tryon, who throws together even very different forms. The specimens from Stat. 2 and 153 are young and dead and could only be identified with moderate certainly by comparison with the upper whorls of adult ones. Wt, JOU ACSODS. Wo FO.

Postnuclear whorls convex, separated by an undulated suture, with rather thick, rounded ribs, 9 or 10 in number on penultimate whorl; these ribs occupy the whole space of the upper whorls, they are slightly angular below a narrow infrasutural excavation, especially on last whorl and become less distinct on base of last whorl, where they disappear at last on the canal. Of the spirals firstly a strong ‘one, with oblong nodules corresponding to the ribs, border the suture, it is accompanied by a much finer one in the excavation, 3 rather strong spirals cross the lower part of each whorl, and amount to about 17 on last whorl and canal, with eventually a narrow intermediate one in the interstices of last whorl. The shell has moreover strong, riblike growth-striae, making the interstices of the ribs somewhat granular. The red-brown colour appears in the interstices of the nodules of subsutural rib, and between the ribs in the excavation, forming on lower part of last whorl, 2 more or less distinct bands, one at the periphery, the other at the base of last whorl, the base of canal is of the same colour, which in some instances occupies nearly 47 A412 the whole space between two ribs.

SoUVERBIE’s much more detailed description is very well applicable to the Siboga-specimens. If the two species ought to be united, the name affixed by Rerve should have priority. Mr. Le Bocxron Tomuin (Journ. of Conch. Vol. XIII, 1910, p. 43) thinks the two are different. 20. Drillia radula Hinds. Hinps. Proc. Zool. Soc. Lond. 1834, p. 16. REEVE. Conch. Ic.

The sculpture of the Siboga-specimens is coarser than that of a specimen from the Gulf of Oman presented to me by Mr. Metvitr, especially on last whorl, but otherwise I see no differences of any importance. These differences in sculpture may be partly due to variability, the localities being very remote, partly be caused by the Siboga-specimens being dead, which renders sculpture more conspicuous, as long as the shells are not worn. 22.

Lond. 1901, p. 436, Pl. 23, fig. 23), but a close comparison with the description and figure, gives the following differences; that species has 8 whorls, a much smaller nucleus of but 2 whorls, it is keeled, which cannot be said of the new species, which has the lirae more regular, on the base the lirae in D. circumvertens are much more close, the total number of lirae however is larger. 25.

Whorls 9, of which about 2 form a smooth, convexly-whorled, brown-tinged nucleus. Subsequent whorls slightly contracted above, not very convex below, separated by a conspicuous, slightly waved suture; sculpture consisting in the excavation of a strong liration, single in upper whorls, divided lower on by a groove, and correspondingly adorned by a single or double row of beads, below this, 2 narrow lirae run still in the excavation; lower part of whorls with a larger number of lirae, 6 in penultimate whorl, about 25 in last whorl, inclusive of canal, with more or less conspicuous intermediate ones in many interstices. These lirae are crossed by oblique, on lower whorls by waved ribs, more conspicuous and remote on upper whorls, closer and fainter on last one, producing beads where they are intercrossing, the last whorl having the appearance of being more or less regularly beaded all over. The brown colour is very irregularly divided, on the infrasutural band it is nearly continuous but on the body-whorl darker brown beads alternate with lighter or even white ones. Last whorl rather convex, attenuated below, ending in a short, rather broad canal. Aperture oval, with a wide sinus above, peristome thin, regularly arcuate, columellar margin concave, running in the canal, which is wide and slightly directed to the left; interior of aperture bluish white, colum- ella with a thin layer of white enamel. . eli, ii, Ives Oa ayoete, allt, Oy, at, 22/q MMII I know no species which is nearly allied to this one, in sculpture it resembles somewhat D. digitalis Reeve, but not at all in shape or colour. 26.

Tryon says (l. c.) it is an immature D. umdzlicata Gray, the quoted localities are “Sierra Leone (Gray); West-Indies (Swirr)’; the Siboga-specimen has not at all a juvenile appearance and this circumstance, connected with the remote locality, may plead for my opinion that the two species may stand. As I have seen no other specimens, I cannot insist on the other important differences in shape and particulars of aperture, between the existing figures. 27. Drillhia dejecta Smith. SMITH. Ann. Mag.

That species is according to description more slender, with 10 ribs on last whorl, but not costate behind peristome, moreover it is tinged with brown between the ribs and at the canal, whereas the last whorl of the new species is smooth, but for a conspicuous rib behind peristome and if quite fresh, it might have been brown behind that rib, at least I find a very faint trace (perhaps bleached) of a brownish colour. 36.

Band 27, p. 11), which is however in nearly every respect specifically distinct, the generic description of the columellar fold agrees very well with the Siboga-shell: “Columella longa, recta et stricta, superne plica transversa valida, hebeti instructa”. Cossmann (Essai de Paléoconch. comp.

Whorls 11, of which nearly 2 form a smooth, convexly-whorled nucleus, subsequent upper whorls nearly smooth, but with a strong keel, which is at first spinous, the spines being horizontally spreading, but soon become more or less upturned and have the character of erect trigonal spines, on the following 3 whorls, spreading again on last one; spines about 20 in number on last whorl. Upper part of these whorls concave, the fasciole smooth, but for fine growth-lines; this fasciole is bordered on the lower whorls by a liration, and the space between this and the spinous keel is faintly 2- or 3-lirate, the space between the keel and lower suture of whorls is con- spicuously grooved, grooves 10 in number on penultimate whorl, about 38 on last one, where some of the upper and many of the basal ones have still intermediate lirae, lacking on the penultimate and older whorls. On the last part of last whorl, the shell is still sculptured by strong growth-lines, which, in crossing the interspaces or lirae between the grooves make them granulous. Last whorl contracted below its periphery, ending in a long, straight canal, which is strongly attenuated towards its base. Aperture elongately subtriangular, its upper margin nearly horizontal, with a deep, rather narrow sinus; outer margin joined to the upper one at a somewhat sharp angle, then slightly convex, thin, slightly fringed, columellar margin concave along the body-whorl, then running straight in the rather wide, long, nearly rectilinear canal, with a strong layer of white enamel on its whole length. Interior of aperture smooth, perhaps slightly grooved at its right margin. Alt. 25, lat. 9'/,; apert alt., with canal 13, lat. 3 Mill. This species may be readily distinguished from the preceding one by its sculpture, con- sisting of deep grooves between flat lirae, of which no trace in the type of A. travancorzca in lower part of whorls, and even in the var. granulata, the granules are separated by shallow striae; the spines of a whorl are more numerous in that species and seem to be less pointed, though this latter difference may be due to the state of preservation. Mr. Metviiz has (Proc. iMaleesoc)) ond: Vol. Vi, 1904, p56, Pl 5; fie. 3) afterwards described another species, A. orientis, from the Gulf -of Oman, which, as that author presumes, seems to be in very juvenile condition; even in that juvenile state, it differs from my species by its much stronger spines and sculpture, as may be clearly seen by comparison with the young specimen from Stat. 137, which has a length of 9.5 Mill. and has already the spiral sculpture and 17 spines on keel of last whorl.

This latter character makes its place in Swrcula somewhat doubtful and reminds Gorsonia, but the fold is rather blunt, like in some specimens of Plewrotoma (Gemmula) con- gener Smith (may it be accidental?) and in other respects it better agrees with many species of Suwrcula, so 1 have located it, though with some doubt, in this genus. 5.

This species, which in many respects resembles some other species of the section Gemmud/a, differs by its sinus aéove the shoulder, near the suture.

Sculpture consisting of numerous, very irregular, spiral striae, more conspicuous at the base of shell and canal, scarcely traceable in the excavation; upper whorls with a peripheral row of obtuse tubercles, which in the uppermost whorls have the character of ribs; these tubercles disappear on last whorl, which has only a more prominent keel-like spiral just below the excavation; the whorls are moreover crossed by numerous growth- lines, strongly curved and conspicuous in the excavation, oblique and sometimes rib-like in the lower part, which produces a wavy appearance of some parts of the shell. Aperture oblong, angular above, ending below in a rather long, broad canal, slightly directed to the left; peri- stome broken, but according to growth-lines with a deep sinus at the suture, then strongly pro- tracted; columellar margin regularly curved, with a thin layer of enamel, slightly contorted along the canal.

If I had seen only 2 extreme specimens, | certainly should have been induced to describe 2 species, the nucleus is in several specimens loosely coiled, the spirals differ considerably in strength, the subsutural granules may be faint or entirely wanting, but these differences are intercrossing, so that I cannot trace a line of demarcation between them and so I left them together. 10.

The shell was of rather obscure nature, scarcely any trace of a sinus was visible and if at all by the aid of the growth-lines, it is very unsignificant, the operculum is not characteristic for the genus; after I had seen the radula, no doubt was left about its belonging to the Plewroto- midae and by its sinus it nearest approaches Swrcula, though the teeth resemble those of 64 429 Pleurotoma s. str., as figured by Troscuer; as the radula of only few species is known, I think the characters of the shell may provisionally decide.

I could not refer this specimen to any known genus, its peculiar shape, which reminds that of Stezraxzs Dall., is still too much different to locate it in that genus. In some degree it seems to be allied to Swrcu/a, and so I have provisionally located it near that genus; unfor- tunately the operculum and soft parts are wanting; though the shell has the appearance of 5) being not adult, it is too remarkable to neglect it. 1.

Aperture oval, rounded above, with a short, open canal below, peristome thin, with a rather deep sinus above, columellar margin nearly straight, with a conspicuous layer of enamel, not appressed, leaving an umbilical chink; interior of aperture with a few lirae. | Nie, tie, Jee, 53 yom. ale, B7/. lev, wi), INI, This species has some resemblance with a very elongate Phos senticosus, but is of course quite different.

Pleurotomella Verrill. Under this name I have united some shells, which agree in having a dark nucleus, sculptured with criss-cross lines, strongly contrasting with the rest of the shell; this group has been united as a section of Mangzlia and of Daphnella by Dati and by Tryon. Datt, in 1908 gives generic rank to Pleurotomella, but unites Gymmnobela as a subgenus, for species with short spire, smaller than the average Pleurotomel/a and erects a new group Phymorhynchus on characters of the animal. As the Siboga-specimens contain no soft parts, I am unable to state if the animals are blind, as P/ewrotomella ought to be, nor if they have the shape of 79 444 muzzle recorded for Phymorhynchus. So 1 am in the less agreeable position of describing several new species, leaving to subsequent researches to decide if they are rightly classified. 1. Pleurotomella btcontca n. sp. Pl.

Whorls 9, of which 4 forma yellowish-brown nucleus, with moderately convex whorls, of which about 2 upper ones smooth, 2 with curved, raised striae, stronger just below the suture, crossed in their lower part by very fine, oblique striae. Subsequent whorls angular, the upper part slightly excavated, basal part nearly straight in outline; this lower part has rather inconspicuous axial ribs, nearly disappearing in last whorl, tubercled at the angle below the excavation; otherwise the axial sculpture consists of rather strong, nearly rib-like, much curved, raised striae in the excavation and very fine growth-lines , of spirals there are 4 on penultimate whorl, below and besides that accompanying the peri- pheral angle, and numerous spirals on last whorl, with eventually intermediate ones; moreover the shell is covered with excessively small granules, only visible under a strong lens. Last whorl at first convex below angle, then moderately contracted. Aperture oblong, with a sharp angle above and a compressed, gutter-like canal below; peristome broken, sinus, judging after growth- lines, large but shallow, occupying the excavated space; columellar margin with a rather strong layer of enamel, strongest at the short canal, where it forms an oblong umbilical pit.

Whorls about 10, of which about 4 form a red-brown nucleus, with convex whorls, of which about 1'/, upper ones smooth, the other ones with angular riblets, strongest near upper suture, crossed in their lower part by fine, oblique striae. Subsequent whorls with a broad, concave upper part and a much narrower lower part. The sculpture consists of 2 conspicuous spirals, just below the suture, less distinctly developed on last whorl, 5 much fainter ones in the excavation; this latter is bordered by a rather strong keel, which makes the whorls angular; moreover a second keel at some distance, with 2 faint intermediate ones on penultimate whorl; the part below the excavation on last whorl is lirate over its whole surface. The upper, excavated part of whorls is crossed by rather distant curved riblets, which, in crossing the infrasutural lirae, produce small beads. At last the whole shell is covered with fine growth- striae and excessively fine granules. Last whorl convex, strongly attenuated towards its base. Aperture obliquely oblong, sharply angular above, ending below in a short, compressed, gut- ter-like canal; peristome broken, probably with a wide, shallow sinus, columellar margin concave, with a thin layer of enamel. : ; IME, ©, law, Be aoest, alle. 22), lem, 1, IMGT This species is no doubt nearly allied to the preceding one, but differs in shape, being 80 more attenuated towards its base and considerably in sculpture, as will be seen by comparing the descriptions. 3. Pleurotomella gradata n. sp. Pl. XXX, fig. 2. Stat. 159. 0°59.1S., 129°48'.8 E. Halmahera-sea. 411 M. Coarse sand. 1 Spec. Shell fusiform, gradate, moderately strong, white. Whorls 8 (uppermost broken), of which 2 form a reddish-brown nucleus, with convex whorls (their number probably will have been 4 of which 2 are wanting), sculptured by curved riblets, crossed by oblique finer ones in the lower part, which is consequently finely reticulated. Subsequent whorls convex, angular, gradate by a conspicuous excavation of the upper part, lower part perpendicular. Spirals consisting of a keel and a few, rather strong, slightly flattened lirae on the lower part, 4 in number on penult- imate whorl and 2 narrow ones at the base of excavation, just above the keel; last whorl with numerous stronger, flat lirae, eventually divided by a very fine groove, and some intermediate ones. The axial sculpture consists of numerous fine growth-striae and curved riblets in the upper part of excavation, less pronounced on last whorl, not quite extending to the keel. Last whorl convex, regularly attenuated towards the rather long canal. Aperture elongate, angular above, ending in a long, gutter-like canal below. Peristome broken, probably with a moderately wide, shallow sinus. Columellar margin concave, with a rather strong layer of enamel along the canal. iGO) alates j.. apert. alt. 57/,, lat. 1°/, Mill. Still allied to the preceding 2 species, but less biconical in shape, with more slender canal and very different in particulars of sculpture. 4. Pleurotomella ceramensts n.-sp. Pl. XXX, fig. 3. Stat. 178. 2°40'S.; 128°37'.5 E. Ceram-sea. 835 M. Blue mud. 2 Spec. Shell shortly fusiform, transparently white. Whorls 8, of which 4 form a yellowish-brown nucleus, with convex whorls, the uppermost broken, the other ones with curved riblets, crossed by oblique, slightly finer ones, over a large part of their breadth. Subsequent whorls rather convex, angular, with a broad, excavated, upper part, a rather narrow, nearly straight, lower part, this lower part with narrow, obtuse, axial ribs, occupying also the lower part of excav- ation, about 17 in number on last whorl, where they are fainter near aperture; these ribs are crossed by 2 strong spirals on upper 2 whorls, 3 on penultimate and numerous ones on last whorl, the upper spiral forming a keel, which is tuberculiferous by the intercrossing of the ribs; moreover there are fainter spirals in some of the interstices and just above the keel, in the basal part of excavation, 3 in number in penultimate whorl; the excavation is crossed by curved riblets or plicae in its upper part, and the whole shell is covered with fine growth-striae. Last whorl regularly attenuated below, with a rather short canal. Aperture angular above and at the erid of keel, with a probably shallow sinus, be!ow the suture; peristome broken; columellar margin with a thin layer of enamel; canal a little broken, probably gutter-like.

(Journ. of Mal. 1904, Vol. XI, p. 84, Pl. 8, fig. 15), but different; the Siboga-shell is considerably less slender, more angular, the excavation is much larger and the sculpture coarser. 5. Pleurotomella clathurellaeformis n. sp. Pl. XXX, fig. 4. Salis w/o Zo MO) So, 129° 37/8 Jd, Comimesea, G8 Wi Idlue mucl, 2 Spec. Shell elongately-fusiform, thin, transparent, white. Whorls about 9, of which about 3 form a reddish-brown nucleus, composed of convex whorls, with riblets in different directions, but the nucleus being rather worn, the sculpture is not prominent. Subsequent whorls convex, with a narrow, excavated part below the deep suture; the excavation is crossed by numerous, slightly curved, axial riblets. The convex part of whorls is sculptured by strong, rounded, oblique, axial ribs, 11 in number on last whorl, crossed by strong spirals, 6 in number on penultimate whorl, of which 4 are stronger and are especially prominent on the crest of axial ribs; these ribs disappear on the base of last whorl, which, as well as the rather short canal is lirate. Aperture oval, angular above, ending below in a rather narrow, slightly curved, compressed canal; peristome thin, with a narrow, shallow sinus above; columellar margin concave, with a thin layer of enamel, directed to the left near the canal. Ete Sys lek 33 aoc, alle, S5/q lat wu MUL, As the nucleus was not in perfect condition, the generic position seemed to be some- what doubtful, but the contrast in colour, between nucleus and rest of shell, the riblets below the suture and other characters it has in common with the preceding species, have at last given the decision. 6. Pleurotomella extensacformis n. sp. Pl. XXX, fig. 5. Stat. 212. 5°54'.5S., 120° 19.2 E. Banda-sea. 462 M. Fine grey and green mud. 1 Spec. Shell ovate, with short spire, rather strong, ivory-white. Whorls 8 or 9 (upper part eroded) of which 3 (or 4) form a reddish-brown, convexly-whorled nucleus, of which about 2 lower ones are sculptured by slightly curved riblets, crossed in their lower part by fine, oblique striae. Subsequent whorls scarcely excavated, the place of the excavation being occupied for a great deal by a rather strong, subsutural spiral, adorned by strong, laterally compressed beads, 22 in number on last whorl; below this spiral remains a rather large groove. Basal part of whorls with narrow, a little oblique ribs, 15 in number on last whorl, ending below the groove in short tubercles, which are connected by a second spiral; the space between the ribs is sculp- tured by fine and coarse growth-lines and faint spiral striae, becoming stronger and groovelike towards the base of last whorl, and have the character of lirae on the short, large canal; last whorl regularly convex, until the canal. Aperture oval, with a moderately sharp angle above and a wide, slightly gutter-like canal below; peristome broken, probably with a very shallow sinus (judging after growth-lines); columellar margin with a thin layer of enamel, concave. Canal directed to the left. Nie, Shien Mate, ATs eyocic, allt, By leven a7, NM 82 447 This species is very peculiar, it has some resemblance with P/eurotomella (Gymnobela) extensa Dall (Bull. Mus. Comp. Zool. Vol. XVIII, 1889, p. 126, Pl. 10, fig. 2), but differs much by the spiral sculpture, which seems not to exist in that species, which is moreover more slender. 7. Pleurotomella abbreviata n. sp. Pl. XXX, fig. 6. Stat. 178. 2°40'S., 128°27'.5 E. Ceram-sea. 835 M. Blue mud. 2 Spec. Shell small, shortly biconical, thin, transparently white. Whorls about 8 (nucleus slightly eroded), of which 4 form a brownish (bleached) nucleus, of apparently the same character as in the preceding species. Subsequent whorls (excepted last one), practically existing only of the excavation, which is sculptured by curved, raised striae and is bordered, just below the suture, by a conspicuous, spiral liration, with laterally compressed, fold-like beads, becoming fainter towards the aperture, and, just above the suture, a second row of depressed, slightly pointed tubercles, forming a keel below the excavation of last whorl, about 12 in number on that whorl, where they form the top of short, oblique, axial ribs; lower part of last whorl, with about 15 lirae and a few intermediate ones. Moreover fine growth-striae and excessively small granules are visible on the whole shell, by the aid of a strong lens; last whorl regularly attenuated towards its base, only slightly convex, with a very short, broad canal. Aperture obliquely oblong, with a sharp angle above and a narrow gutter-like canal below; peristome thin, with a wide, moderately deep sinus above; columellar margin slightly concave above, straighter and directed to the left along the canal, with a thin layer of enamel, thicker below. i mOwmlteeouprecapeniaralte 4aqlat. 1m Mall: This species is quite different from any of the preceding or elsewhere known ones by its shape and sculpture. 8.

Whorls 8, of which 4 form a light-brown nucleus, with convex whorls, remote riblets on the upper part, oblique, and less stronger ones, which cross each other, in the lower part. Subsequent whorls scarcely convex, with only a trace of being divided into 2 parts on the upper two; however, the upper part is marked with elegantly curved, conspicuous riblets, being slightly bead-like just below the suture, on a narrow, infrasutural spiral; lower part of last whorl, with numerous, faint, spiral striae, stronger on the rather long, slender canal; moreover the lower whorls display elegantly waved growth-lines. Aperture oval, with a sharp angle above and a narrow gutter-like canal below, which is directed to the right. Peristome much broken, probably with a wide, shallow sinus above; columellar margin with a very thin layer of enamel, slightly stronger along the canal. Nite ldtayse |. apentedlt.

Whorls about 9, of which about 3 form a reddish- brown nucleus, with crossed riblets. Subsequent whorls angular, the upper part excavated, with remote, faint, axial plicae below the suture, nearly lacking in last whorl; lower part with rounded, more or less oblique ribs, ending above, just below the excavation, in bluntly pointed tubercles, 13 or 14 on last whorl, otherwise this lower part is smooth, but for numerous growth-striae and a few, scarcely appreciable, spiral striae; near the base of last whorl however and especially on the rather long, narrow canal, numerous spirals make their appearance. Aperture elongately ovate, with a sharp angle above, a narrow gutter-like canal below; peristome thin (broken), according to growth-lines with a wide, shallow sinus above; columellar margin rather straight, with a thin layer of enamel.

From the same locality, a heavily broken shell, with the lower half of whorls spirally grooved, 7 grooves on penultimate whorl, has been dredged; the specimen is larger, but other- wise I see no differences of much importance, the more so, as the two specimens of the type are even not perfectly identical; as a large portion of last whorl is broken away, the shell appears to be much more slender, but if complete, this difference would disappear for a good deal, so I preferred to mention it only as a variety; the nucleus, though eroded, allows to trace the characteristic sculpture; length 24 Mill.

Nucleus wanting, remaining whorls 9, moderately convex, slightly excavated below the conspicuous but shallow suture. Sculpture consisting of remote, oblique, axial ribs, conspicuous in upper whorls, fainter lower on, disap- pearing on back of last whorl, forming tubercles below the excavation, which in upper whorls bears short plicae, just below the suture; the lower part of whorls is crossed by very numerous 34 449 spiral striae, conspicuous in upper whorls, faint on last one, but stronger towards and on the canal. Aperture elongately-oval, angular above, with a wide canal below; peristome damaged, according to the fine growth-lines, with a very shallow sinus above, then regularly arched; columellar margin concave above, then nearly straight, at last slightly directed to the left, covered with a layer of enamel, which is thin above, stronger below.

A rather doubtful species, which | thought might still belong to Swrcu/a, but Mr. Smirn, who compared it in the British Museum, thinks it may be a Sfergo, a group described by MAGEE rocwUe sen Natenvias: Vol, XVII, 1894; p. 680), with :2 Species (I. c. Pl. 24, fi Pl. 31, fig. 11); unfortunately the nuclear whorls, which ought to be of a Szzws¢gera-character, ge 5 ’ with oblique, reticular, curved sculpture is wanting, as well as the soft parts, with or without an operculum. Of the two species described and figured, it resembles more S. daphnelloides Dall in shape and sculpture. I have followed Mr. Smirn’s advice, though, under these unfavorable circumstances, with considerable doubt. Daphnellopsis n. gen. Shell elongately-fusiform, with smooth nucleus, aperture elongated, with a strong varix exteriorly, behind the peristome, which, in some measure is double, the internal peristome with a horizontal upper margin, a denticulated outer one, with a wide shallow sinus at the point of junction and an angle at the entrance of the short, slightly upturned canal; columellar margin slightly concave above, with a conspicuous layer of enamel.

Whorls 6, of which about 1!/, form a convex, smooth, slightly inclining nucleus; post-nuclear whorls convex, separated by a deep suture. Sculpture consisting of numerous, lamellose ribs, 26 in number on last whorl, besides a sharp one behind peristome; these ribs are waved by the intercrossing of spiral lirae, 4 principal and a few intermediate ones on penultimate whorl, more lamellose and prominent near the aperture and at the base and canal of last whorl, where they amount to about 16; true peristome strong, with 6 denticles below upper sinus and another at some distance, at the entrance of canal, the so-called exterior peristome, consists of many layers around upper sinus.

First measurements of the largest specimen with nucleus, but no developed inner peris- tome, second ones of specimen without nucleus, but with the peristome quite complete. This remarkable species is one of the puzzles of the Siboga-collections. It is impossible to locate it with any certainty in one of the groups of Gastropods; the sinus makes it probable 35 450 that it is a Pleurotomoid, and in this case, nearest allied to Daphnella or Clathurella, its very shallow sinus pleads for the alliance with Daphnella;, only the soft parts could probably give light, but unfortunately they are wanting.

Several other specimens belong to several groups of the P/leurotomzdae, but are too young or bad or both for description; only in few cases I have mentioned them, but in view of the doubtful generic position, I have omitted the majority, which manner is certainly no loss to science. 86 APPENDIX. Here follow a few species, which have been found in tubes or boxes and have been overlooked, partly because they were concealed in the aperture of larger species, partly by their real affinity not having been recognized, when the collection was provisionally arranged in larger and smaller groups; so for instance those now recorded as Z7vophon, which, with their damaged peristomes made the impression of belonging to the Pleuwrotomzdae, until a closer examination, brought to light the total absence of the characteristic sinus. leew ik IE ke pee coy aiter, N° 1 add: 2.

Though the mollusks dealed with in this part, do not belong to the Prosobranchia, Prof. WerBer thought it would be fit, that I should record them. It was not without hesitation that I have undertaken this task, as far as concerns the Ofpzsthobranchia Tectibranchiata, Tribe Bullomorpha, the Nudibranchiata and other tribes of Tectibranchiata, even one species belonging to the Tribe Bullomorpha, having already been treated by R. Bercu (monograph L); but with the kind assistance of Mr. SmirH, who compared many of the small species, with the numerous forms which are described, but not figured by Apams and other authors, I have now accomplished it. The present part contains 19 species of land- and freshwatermollusks, of which 2 are new to science, and 41 species of Ofzsthobranchia Tectibranchiata Bullomorpha, with 15 n. sp. and a few varieties.

The specimen is of rather typical shape, not quite adult, light redbrown, with a dark brown band accompanied by a white zone, it agrees moderately well with the figure of v.

This specimen is violet-brown, with a dark brown band just above the periphery, a whitish zone below it, with a faint, very narrow, brown band, accompanying the large one and a narrow, brownish line below the suture, bordered by whitish. Fig. 96 of Tryon is the nearest ally in colour. Hemiplecta Albers. 1. Llemiplecta peaseana Pfeiffer. DFBIMNMNIR, JOC, ZOO SOc, ILOncl, WHOA, jo OOS —— Monogr. Heliceorum, Vol. V, p. 77. 2 455 Vv.

Near Noimini, South coast of Timor and in the river-bed. 4 Spec. One young specimen has been taken alive, 3 specimens from the river-bed are dead, bleached shells, of which 1 or 2 full-grown. As the specimens agree with my stronger sculp- tured ones, from more than one locality, I have kept them separate from Mantua rareguttata Movusson. 2. Llemiplecta kangeangensis n. sp. Pl. XXXI, fig. 1. Stat. 16. Bay of Kankamaraan, South coast of Kangeang. 2 Spec. Shell depressedly-conoid, umbilicated, carinated, horn-coloured, with a whitish keel, accompanied by a narrow red-brown zone or line. Whorls 4?/,, slightly convex. Nuclear whorls with very fine, radial striae or riblets, becoming stronger on subsequent whorls, where they are more like curved ribs, the ribs being crossed by spiral striae, interstices smooth; near aperture these striae are again fainter, on the 34 and subsequent whorls, the keel is per- ceptible as a slightly depressed, white zone, just above the shallow suture; last whorl moderately depressed, angular by the prominent keel, its basal surface convex, much smoother, shining, of a lighter colour, slightly darker round the pervious umbilicus; aperture depressedly ovate, scarcely angular by the keel, moderately oblique, its upper and basal margins regularly convex; peristome slightly thickened, more so at its insertion near the umbilicus, where it is dilated and partly covers the umbilicus. Diam. maj. 26, alt. 15'/,; apert. alt. 9, diagonally 10; lat. 13; umb. lat. 2 Mill. Of this species one specimen is adult but not intact, having a large hole in its spire and the peristome is slightly broken at its upper part, the other specimen is not fullgrown, however they are sufficient for description and comparison. The species may be distinguished from its allies A. dataviana, arguta etc., by its regularly convex shape, by its smaller size, scarcely perceptible umbilical darker spots and much finer sculpture, which is decidedly riblike in the allied species.

Marrens’ type, the largest having a diameter of 121/, Mill. instead of 11, an altitude of 8'/,, instead of 7 Mill. and is less depressed in shape; only 2 specimens have the bands quite hyaline, in the other ones a con- spicuous brown peripheral band and a narrow subsutural one of the same colour, distinguish them from a specimen formerly received of v. Martens; as however these differences are more gradual, as a few specimens are of the typical size, shape and colour of bands, and the characteristic sculpture, consisting of strong ribs on the upper surface, with a nearly smooth base, agree with v. Marrens’ description, there is, I think, no doubt that they belong to the same species, which came from Dana, an island southwest-wards from Savu. Plectotropis v. Martens. 1. Plectotropis kangeangensis n. sp. Pl. XXXI, fig. 2. Stat. 16. Bay of Kankamaraan, South coast of Kangeang. 2 Spec. Shell widely umbilicated, carinated, convexly depressed, thin, fragile, opaque, white. Whorls 4, rapidly increasing, slightly convex above, with a slight depression near the suture, which is conspicuous, more so as the keel is prominent on penultimate whorl. Nucleus not con- vex, nearly smooth, but under the lens with very fine wrinkles; on the second and subsequent whorls, the sculpture consists of stronger, radial striae, nearly riblike in some parts, crossed by fine, spiral striae; last whorl with a conspicuous, though not sharp, compressed keel, fainter near the aperture, basal part of last whorl much more convex than upper part, with the same sculpture, though a little less coarse. Aperture oblique, angularly lunar, its upper and basal margins convex, columellar margin nearly straight (damaged), joined with the basal one by an obtuse angle; peristome rather thin above, slightly expanded, thicker and narrowly expanded near base. Umbilicus rather large, pervious, funnel-shaped, bordered by an obtuse angle. Diam. maj. 171/,, alt. 10; apert. alt. 5; diagonally 7, lat. 6%. umb. lat) (o7/) Mulk Unfortunately this interesting new species is not represented by an intact specimen, one 4 457 of them is still young, the other one is adult, but has a large hole in the spire and the columellar margin is broken; it is allied to P. rotatoria v. d.

Of the 12 specimens, there is but one that possesses only the peripheral band, the other specimens have a larger or smaller number of narrow lines of lighter colour, as in PretrrEr’s figure (I. c.) and as those of Pirspry. The variety, originally recorded from Tukan Besi by PFEIFFER, has already been recorded by Fuiton as JZazs, from Talaut, by Pirssry from the Philippines. A specimen from FuLron in my private collection is: multifasciate, but otherwise perfectly agrees with the Siboga-specimens. 2. Cochlostyla (Crystallopsis) najas Pfeiffer. PFEIFFER. Symb.

Marrens. The narrow, yellowish, subsutural band, figured by Putvippr, which v. Martens. could not find, is present in some of the specimens; it seems to be more a layer of enamel below the suture, visible by the transparency of the shell, than a true colour-band.

SiAls He Sele, Sav, Uo to a7 Wl, Same, 7 Sec Apams describes the species as smooth, Watson and Pirssry mention fine, remote, spiral striation; the Siboga-specimen is in very fine condition, it very well agrees with Pirssry’s figure, but I should not call the striae remote, though they are narrower than the interstices, they are not visible on that figure. Kopetr has given a coloured figure of the species, on plate B of his Lullacea, in the second edition of the Conchylien-Cabinet ; this dorsal view, with the animal, but without description, shows a more remote striation, but is less characteristic than the beautiful plates, representing the empty shells in Kopett’s monograph.

Shell rather large for the genus, oval, thick, white, with raised spire. Nuclear whorls broken, remaining whorls about 3, (worn), separated near the aperture and probably higher on, by a narrow, channelled suture; last whorl contracted below the suture, then flatly convex, rounded near the base. Sculpture consisting of very fine radiating or growth-striae, stronger at intervals, more conspicuous on upper part of last whorl, and numerous spiral striae, which are raised on the upper part, impressed on the lower part of body-whorl, the interstices are con- Io 403 siderably broader than the striae, even near the base, where they are more crowded. | see about 13 raised striae, of which the upper ones are fainter, and, I think 4o—so impressed ones, the condition of the shell not allowing a reoular counting. Aperture elongately-pear- shaped, narrow above, sharply angular at the summit, rounded below, peristome broken, its contour in accordance with the body-whorl, contracted above; columellar side with a (partly removed) layer of enamel, the columella concave, thick, reflected over the umbilicus, as a thick enamelled plait, nearly concealing an umbilical slit. Pultwowlat. 3/2; apert. alt. 41/,, lat. 1°/, Mill. Though this specimen is in bad condition, its large size and particular characters, more- over the great depth at which it has been dredged, induced me to describe it. I know no species which is like it. Volvulopsis n. gen. Shell elongately-ovate, conically pointed above, rounded and but little contracted below, last whorl forming practically the whole shell; spire a small, apparently not pervious pit, nearly concealed by enamel. Type: V. ancillartorides Schepm. This new genus has some resemblance with Vo/vz/a, but the spire is much less pointed, the base more rounded; unfortunately the soft parts are wanting, so the systematic position could not be ascertained as well as might be desirable. Under these circumstances I have located the genus near the place occupied by Volvula. 1. Volvulopsis ancillariowdes n. sp. Pl. XXXI, fig. 4. Sidious Aneel LOwsO- 7H. savu-sed. O59 Ml.

Shell elongately-ovate, upper part much contracted, forming a short cone, with convex sides, white, only one whorl visible, forming nearly the whole shell, but for a scarcely visible top of the spire, which is encircled by a sharp margin, enclosing a small hole in one specimen, nearly and probably always concealed by enamel, in the adult. Sculpture consisting of rather remote lines of growth and crowded spiral striae, raised near the upper part, impressed near the base and on the median part, where they are much fainter in one specimen (perhaps by erosion). Aperture as long as the shell, ending above in a narrow canal; peristome broken, slightly convex at the upper part, nearly straight lower on, running uninterruptedly in the broadly rounded basal margin. Columellar side convex, with a conspicuous layer of enamel; columella nearly straight, thickly enamelled, probably slightly truncated. Niet 7 latea7 se apert. lat. 4 Mull. The two specimens are somewhat different, that from Stat. 52 being a little more convex, with somewhat stronger sculpture; as both specimens are more or less defective, this latter character may depend on the state of preservation. Though it was impossible clearly to define every character, the species is too remarkable to be neglected. Wit 464 Fam. SCAPHANDRIDAE. Meloscaphander n. gen. Shell ovate, convex in its upper part, attenuated below, with low, exserted spire; aperture shorter than the shell, large; columella moderately curved, thick.

Stat. 221. 6°24'S., 124°39 E. Banda-sea. 2798 M. Solid bluish grey mud with foraminifera. [I Spec: Shell ovate, broadest in its upper half, obliquely attenuate below, rather strong, yellowish under a brown epidermis. Whorls 2h, forming a short spire, slightly eroded, separated by a deep suture, probably a little convex, but the characters of upper whorls are obliterated by erosion; last whorl large, strongly rounded in its upper part, more straightish in its median part, narrower below. Sculpture consisting of spiral lirae in upper part, (about 16 in number), which are often double and are crossed by riblets, giving a cancellated appearance to that upper part; lower on the lirae disappear and have the character of a smooth surface, with about 60 spiral rows of rounded pits, the basal part again with a few (about 5) lirae. Some of the spiral rows of median zone are very fine, the majority is rather coarse. Aperture pear-shaped, with a rather acute angle above, becoming soon broader, much so below, slightly compressed at the base; peristome rather thin, regularly curved, though more above and below, than in median part; body-whorl with a conspicuous layer of enamel on its moderately convex columellar side. Columella concave, thick, not angular below, thickly reflected and quite covering the umbilical region. Ne WG, lake, NOs aos. ali, wy, lee, ©, Mili, Of the three gizzard plates, two are large, subquadrate, with strongly rounded angles, rather thick, calcareous, broadly rounded at the largest extremity, where they are yellowish- white and thinner, one of them nearly straight at the opposite margin, where it is dark brown and thick, lateral sides slightly undulated; the other plate has the front- and backsides more rounded, but otherwise it is similar; the interior of these plates is convex, with a nearly smooth, subcircular centre and a broad, concentically striated margin, exteriorly these plates are concave in their broadest part. The third plate is much narrower, elongate, strongly compressed, brown with darker growth-striae, and has much the appearance of a gaping, equal-sided Umzo pectorum. Length of largest plates about 4'/,, their greatest breadth 41/,, narrowest part 31/, Mill., smallest plate, long 3}/,, high 11/, Mill. The radula has given only a poor result; as the soft parts seemed to be decayed, I obtained only a few separate lateral teeth, 1 could find no median ones; probably they were lost, as, according to Brrcu, is often the case; one of the laterals (1), in a favorable position, 12 465 has the shape of a curved sword, with a rounded knob, and is finely serrated at one of its margins, a little behind the top. The shape and disposition, as well of the gizzard-plates as of the lateral teeth, four of which are zz sé¢w, displayed the appearance of the ribs of a quadruped, as in Scaphander, and are in accordance with my locating the species amongst the Scaphandridae, though, if this be right, the family-characters ought to be altered in accordance with the slightly raised spire in the new genus.

Sculpture consisting of more or less unequal growth-striae, having at intervals the appearance of folds, and numerous spirals, which, on the ventral side, have often the appearance of rows of impressed punctures; on the back and near the aperture, they are more like impressed spiral grooves, with faint punctures; towards the base the grooves are deeper and partly distinctly punctured, however this sculpture varies considerably in different specimens, the punctures being more distinct in some specimens than in other ones. Spire concave, but the spiral perforation is quite concealed by the enamel and bordered by a sharp keel. Body whorl moderately convex. Aperture wide, especially below, where it is dilated; its upper margin forms a large, rounded wing, much surpassing the spire, outer margin slightly convex, basal margin regularly rounded. Columellar side of body-whorl not very convex above, strongly concave below, the body with a strong layer of enamel. Alt.

(from apex to base of apert.) 25, lat. 20, apert. alt. with wing 28, lat. above 7, below 14'/, Mill. This species has some resemblance with S. mundus Wats., but the wing of the aperture is much larger, the aperture is much broader in its lower half, the columella of the new species being much more concave, the basal part of peristome is more regularly curved in S. mundus, dilated in S. Széogae, the sculpture is different, though variable, as stated above; the specimen from Stat. 208 is very small (young) and strongly punctured. Perhaps it is different, but I would not describe another new species on a rather similar specimen, the differences of which may depend on age; the first recorded measurements are of a fine specimen with epidermis, which has served for description, the other ones of the largest, somewhat bleached specimen. 2.

Shell oval, upper part rather much attenuated, moderately strong, white under a yellowish 13 466 or brownish epidermis. Sculpture consisting of more or less conspicuous growth-striae and more or less close-set spiral rows of rounded punctures, which are especially conspicuous on the ventral side, and, in most cases, much less so towards the aperture, where they have in many instances the appearance of slightly punctured spiral striae; near the base the interstices have nearly the character of lirae. Spire concave, concealed by an enamellous deposit, bordered by an obtuse keel. Body-whorl not very convex. Aperture wide, especially in its lower part, which is much dilated; its upper margin scarcely winged, elevated only a little above the body-whorl; outer margin nearly straight, basal margin regularly rounded. Columellar side of body-whorl not very convex above, covered by a thin layer of enamel, very concave below. Alt.

Martens (Die beschalten Gastropoden der deutschen Tiefsee-Exped. 1898—g9, p. 131, Pl. 5, fig. 19), but it is considerably more attenuated above, the body-whorl is much less convex than in the figure of v. Martens, the sculpture seems to be different; however sculpture scarcely seems to be a very constant character, as will be seen in the description of my new species, the development of the punctures differing considerably in some parts of the shell; in some specimens very fine intermediate rows of punctures are perceptible, scarcely present in other ones, the colour varies from yellow-brown to rather dark brown, even though being quite fresh and containing the soft parts; however these differences can only be individual, otherwise nearly every specimen should be a species. The same observations about sculpture have been made in the preceding species. Likewise the different measurements have been made after the same rule as in S. Szdogae. 3. Scaphander subglobosa n. SO.

Sculpture consisting of folds, more crowded at the beginning of last whorl, more remote near the aperture, and spiral rows of relatively large punctures, occupying a large part of the shell, but less conspicuous towards the aperture and separated by narrow interstices, which are narrower and more raised on the basal half, with true lirae near the base. Spire concave, concealed by a deposit of enamel, bordered by a very low, rounded, white margin. Body-whorl rather convex. Aperture wide, dilated below, upper margin with a small (broken) wing, outer margin regularly but not strongly convex, basal margin regularly rounded, columellar side strongly convex along the body, which is covered by an orange layer of enamel; lower part or true columella strongly concave. : Alt.

Both specimens have the appearance of being young; as both are moreover defective and the shape has no prominent characters, I think it not advisable to name them; the shells are much more elongated than the young specimens of A. mawcum and have only a very faint columellar fold. The species much resembles A. hyalina Watson, but seems not to be identical, as Mr. Smiru, who compared it in the British Museum, has not identified it. Le 468 3. Atys multistriata n. sp. Pl.

Shell elongated, with slightly convex sides, attenuated above, thin, transparent white; sculpture consisting of growth-striae, which are rather coarse in some parts of the shell and especially towards the spire, where they are more crowded, being more remote and fold-like on the rest of body-whorl; the whole shell is covered with fine spiral striae, very fine and nearly microscopic on the central part, more conspicuous towards the extremities. Spire umbilicated, enamelled, with a rounded border. Aperture very narrow above, larger below, lip rising from the vertex, arched but not contorted, forming a regular sinus above, outer margin slightly convex, thickened interiorly; basal margin forming a compressed sinus, columellar side scarcely enamelled on the slightly convex body; columella short, slightly concave, with a small, contorted fold at its base, making it slightly truncated; behind the columella an elongated, narrow, umbilical slit is bordered by a rounded margin.

Shell convexly-oval, attenuated and contracted above, narrow below, thin, fragile, white. Sculpture consisting of very fine growth-striae and at both ends, strong spiral striae, which are not crowded, though a little closer at the extremities; a median zone, scarcely a third part of the total dorsal length, remaining smooth, except for excessively minute, spiral striae, traceable on nearly the whole shell, under a very strong lens. Spire concave, with a small enamellous centre, bordered by a rounded, opaque, white rim; below this rim the shell is slightly contracted. Lip from its inferior to upper part, slightly contracted, forming an angle at its junction with the outer margin, by the ending of the circum-apical rim; the outer margin at first concave Lo 469 for a short space, then rather convex, until the compressed basal margin; columellar side strongly convex along the body-whorl, which is rather ventricose and covered by a very thin layer of enamel; columella slightly concave above, slightly reflected over an umbilical slit, which is bordered by a very faint rim; columella slightly truncate below. Alt. from apex to base of apert. 6, lat. neary 4'/,; apert. alt. 7, lat. above */,, below 1'/, Mill. The species seems to be allied to the preceding one, but differs in colour, being white instead of yellowish; the spiral sculpture, which occupies only the extremities of body-whorl in tortwosa but extends over more than */, in the new species; above and still more below, the shell is less attenuated, the umbilicus is smaller and less sharply bordered in the latter species, though some specimens seem to be less ventricose than other ones, the least ventricose ones are still more inflated than f.i. A. attenwata and other allied species. The differences between the specimens in this respect, may be due to age or to the state of preservation, some of them being more or less broken at the peristome; the measurements are those of the most complete specimen. Nearest, even perhaps too nearly allied, is the recently described A. chelidon (Proc. Mal. Soc., Vol. X, p. 253, Pl. 11, fig. 16; Oct. 1912), but that species is more slender, and, according to figure, the aperture is more rounded above. 6. Atys (Alicula) cylindrica Helbling.

Sits WO2, OAc IN ACO AM IT, 835 Wil uw Sjoec, Shell oval, ventricose, rather solid, yellowish-brown. Sculpture consisting of some spiral lirae, about 12 in number on the upper part of shell, occupying also the upper umbilical pit, and of which the lower 2 are considerably flatter; these lirae and not less their interstices are crossed and consequently cancellated, by finer, but still sufficiently conspicuous, radiating riblets; below the last of the lirae, run 2 spiral rows of fine punctures. Near the base run a few spiral rows of strong punctures, the 2 most basal ones accompanied by lirae, then follow higher on 3 rows of larger punctures, with nearly flat interstices and still higher up 2 spiral rows of small punctures; at last near the base of the otherwise nearly smooth median zone, still one row of very small punctures; this smooth space is crossed by irregular, sometimes fold-like growth- striae. Spire concave, with a small patch of enamel at its bottom, otherwise lirate, as described above, with a rounded rim. Aperture elongate, moderately narrow above, wider below; peristome strongly contorted near the vertex, then produced in a narrow wing; outer margin regularly convex, basal margin rounded; columellar side of body very convex, with a rather thick layer of enamel, which is rugose (perhaps abnormal), columella concave, broadly spread over the umbilical space. Alt. from vertex to base of apert. 57/,, lat. 4; apert. alt. 6, lat. above 1/,, below 2 Mill. This species is remarkable for its prominent sculpture of upper part of body-whorl.

Sculpture consisting of very fine growth-striae and a few spiral striae which are rather faint and not crowded, near the base. Spire umbilicated, rather wide and deep, showing the whorls, about 3 in number, not enamelled, bordered by a rounded margin, divided by a single spiral groove; body-whorl nearly straight above, then convex. Aperture elongated, narrow above, large below; upper margin of peristome forming a small, rounded sinus, outer margin nearly straight, even slightly contracted above the middle, then slightly dilated; basal margin rounded. Columellar side of body-whorl convex, covered with a thin layer of enamel, columella short, concave, with a tooth-like fold at its basal part; no trace of umbilicus. Alt. from margin of spire to base of apert. 31/,, lat. 2; apert. alt. 3°/,, lat. above 1/,, below 21/, Mill. This species may be distinguished from LD. dentifera and monodonta, by its strongly truncated spire and by being attenuated at the upper part, monodonta being more cylindrical, dentifera regularly oval. One specimen is slightly worn, but has the tooth-like fold more con- spicuous, than that which has served for description. Both specimens are empty shells, consequently it is not certain that they have lived at the recorded depth. Cylichna Loven. 1. Cylichna javanica n. sp. Pl. XXXII, fig. 6. Stat. 4.

Shell ovate, roundedly-truncated above, more contracted below, thin, pellucid, white. Sculpture consisting of rather strong, radiating striae and a few conspicuous, impressed, spiral striae, at the upper and basal part of body-whorl, the median part of that whorl being covered with very fine, close-set spirals, only visible under a strong lens. Spire concave, but scarcely umbilicated, quite or nearly concealed by the enamellous point of junction of the peristome, the border of the spiral excavation is rounded, the space within that border is opaquely-white, by an internal layer of enamel, visible at the peristome. Aperture elongate, with raised, rounded upper margin, somewhat contorted at its insertion; outer margin thin (broken), moder- ately curved, more so above and below, narrow, compressed, gutter-like at the base. Columellar side of body-whorl convex, with a thin layer of enamel; columella concave, forming a strongly contorted fold at its lower part, ending below in the basal gutter, reflected over the umbilical region, which is bordered by a blunt rim of the same opaquely-white colour as the spire.

The preservation of the specimens was rather bad, nevertheless I got a defective radula and 3 gizzard-plates. I found many rows of teeth, the laterals (1) have a subquadrate base and a simple, long cusp; as median tooth (M) I may consider a triangularly rounded object, but I see no cusp. The gizzard plates are brownish, with a median keel, they are many-articulated, having the appearance of a contracted, many-valved chiton; length of gizzard-plates about 1, breadth about */, Mill. These plates and the laterals are in accordance with what is known of ffamznea, and so I have left the species in that genus, though with some doubt, as the simple shape, of what I consider to be the median tooth, is more that of Atys, as figured by Bercu in Semper’s “Reisen im Archipel der Philippinen’. The measurements of latitude of shell are not quite trustworthy, as the peristome is more or less broken, especially in the largest specimen. Fam. HypaTINIDA®. Hydatina Schumacher. 1. Hydatina sp.
