costis longitudinalibus acutis (in anfr. ultimo circa 12 versus peripheriam obsoletis) incrementique striis ornati, et sulco levi supra costas continuo superne divisi; anfr. ultimus magnus, lira acuta circa caudam cinctus; columella fusca. Long. 11 mill., diam. 33. Hab. Persian Gulf (Colonel Pelly). This species has no spiral sculpture. The longitudinal ribs are thicker at the top; and being cut across by the narrow transverse furrow a little below the suture, the appearance of a narrow infrasutural belt is thus produced. Terebra (Myurella) fuscocincta, sp. nov. Testa parva, subulata, nitens, albida vel cornea, lineis duabus fuscis cincta, altera saturatiore paululum infra suturam, altera fere ad anfractuum basim; anfract. ultimi basis fusca; anfr. 10, convexiusculi, infra suturam leviter constricti, costis validis, acutis, arcuatis, superne subtubercularibus (in anfr. ultimo circiter 10 vix ad basim attenuantibus) instructi; columella brevis; cauda lira distincta cincta; canalis brevis, latus. Long. 8 mill., diam. 2. Var. anfr. planiusculis, costis rectis munitis. Hab. Persian Gulf (Colonel Pelly). This species is coloured somewhat like pumilio, but is at once distinguished from that form by the absence of the transverse striation and by the existence of fewer ribs. The upper brown line or band is quite at the top of the whorls in pumilio, whereas in the present species it is a little below the suture, colouring a slight depression or constriction which exists there. The variety is allied to tenera, Hinds, which, however, is shorter, has fewer ribs, and wants the brown line near the base of the whorls and that around the periphery. Terebra (Myurella) MacAndrewii, sp. nov. Testa parva, breviter subulata, parum nitida, albida, zonis duabus (supera paululum infra suturam purpureo-nigricante, infera aliquanto suturam supra fuscescente costis albidis fere interrupta) cincta; anfract. 11, convexiusculi, superne leviter constricti; costis longitudinalibus parvis superne impressione spirali levi divisis. (in anfr. ultimo 12-13 basi sensim attenuatis) instructi, et striis gracillimis, creberrimis, spiralibus ornati; anfr. ultimus zona tertia fuscescente infra peripheriam cinctus; columella brevis, purpurascens; labrum aliquanto expansum; canalis perbrevis, latus. Long. 13 mill., diam. 4. Hab. Persian Gulf (Colonel Pelly). This is one of the very numerous and beautiful species presented to the British Museum by the late and deeply lamented Robert M'Andrew, Esq. The slight blackish purple depression, a little below the suture, dividing the longitudinal ribs, forms an obscure nodulous infrasutural belt. The three exterior coloured bands, which are interrupted by the whitish ribs, are visible within the aperture in the form of three series of squarish spots. Terebra (Myurella), cognata, sp. nov. Testa subulata, dilute fuscescens; anfr. 12, primi 2 læves, convexi, lilacei, cæteri planiusculi, costis longitudinalibus rectiusculis (in anfr. ultimo circa 12 basi productis) instructi, et superne sulco parvo spirali inter costas præcipue conspicuo insculpti, lirisque transversis supra costas subobscuris cincti; anfr. ultimus quadratus, ad peripheriam zona angusta albida inconspicua ornatus; canalis brevis, aliquanto recurvus. Long. 14 mill., diam. 3. Hab. Persian Gulf (Colonel Pelly). Allied to polygyrata, Desh. ; but the transverse sculpture of the latter is coarser, as is also the infrasutural sulcus or punctured line. Terebra (Hastula) rufopunctata, sp. nov. Testa subulata, nitens, pallide olivacea, infra suturam zona angusta alba, et infra illam zona secunda livida cincta, et supra zonam albam punctis pluribus, parvis, rufis, notata; anfractus 12, primi duo læves, vitrei, convexi, cæteri plani, costis vel plicis tenuibus numerosis, acutis, versus basim anfractuum evanidis, ornati, sutura obliqua sejuncti; anfr. ultimus circa peripheriam albo zonatus, et infra illam zona livido-fusca cinctus; apertura parva; canalis brevissimus, latus, levissime recurvus; columella medio leviter arcuata, ad basim carina unica succincta. Long. 22 mill., diam. 5. This species must not be confounded with strigillata, L., to which it has considerable likeness as regards the coloration. It may be at once distinguished by its acute plications, which do not extend to the bottom of the whorls, whilst those in the old species are quite flat and reach from suture to suture; and the body-whorl of the former is shorter than that of the latter.

In the Annals and Magazine of Natural History,' 1873, vol. xi. p. 262, I made a few remarks on a species of Terebra which had been referred by Messrs. Deshayes, Hinds, and Reeve (partly) to T. aciculina, Lamarck. Since writing the paper referred to I have had occasion to reexamine this species, and find that it is not in fact the Lamarckian shell. In his diagnosis, which appears almost as if it were extracted from Born's description of T. cinerea ( Index Musei Vindobonensis,' p. 267), from the similarity of language, he gives "albidocinerea" as the colour of the species, which evidently in no way applies to the present species, which is of a more or less ashy-brown colour, banded with white beneath the suture, and also longitudinally streaked with brown, and has a white zone around the last whorl a little below the middle, which is also distinctly seen within the brown aperture. M. Deshayes, in the second edition of Lamarck's Animaux sans Vertèbres,' vol. x. p. 250, remarks that Lamarck was wrong in changing Born's name cinerea to that of aciculina if his shell was the same as that of this author, and he considers Born's species identical with that described by Lamarck under the name of Terebra cærulescens. This, however, is a palpable mistake; for the latter is a smooth shell without any striation or plication beneath the suture, differently coloured, and has the sutures indistinct ("suturis obsoletis," Lamarck), which arises from the fact of the whorls being encircled by a narrow callosity just above, but contiguous to, the suture, which peculiarity induced me to found the subgenus Impages for this and a few other species possessing the same characteristic. The synonymy of T. cærulescens and T. cinerea is as follows: Terebra (Impages) cærulescens, Lamarck, Animaux sans Vert. ed. 2, vol. x. p. 245; Kiener, Coq.

XIX.-New and peculiar Mollusca of the Patellida and other Families of Gastropoda procured in the Valorous' Expedition. By J. GWYN JEFFERYS, LL.D., F.R.S. Patellida. Tectura rubella, Fabricius. Patella rubella, Fabr. Fn. Gr. p. 386. BODY greyish-white, with numerous and close-set brownish streaks in front: head semicircular: mouth concave, opening horizontally, and puckered: mantle thick: tentacles awlshaped, contractile, with blunt tips: eyes small, black, sessile on the tentacles at their outer base: foot oval. Sluggish. Godhavn, 5-20 fms.; Station 4, 20 fms.; 5, 57 fms. (dead); Holsteinborg, 3-12 fms. Greenland (Fabricius and others). Spitzbergen (Torell)! Tromsö, Norway (M. Sars). Labrador (Packard, fide Whiteaves); Newfoundland (Verkrüzen) ! Young shells have a butotn-shaped (and not a spiral) apex, which turns to the broader and longer end, as in Lepeta; but in the latter genus the apex is spiral. The apex is strongly striated lengthwise, and resembles that of Ancylus. In a Greenland specimen, which I received from Dr. Mörch, I found two fry with perfect shells enclosed in the concavity of the foot. Perhaps T. rubella may be the type of a distinct genus (say Erginus, from one of the Argonauts). I see no reason for changing the opinion which I expressed in the third volume of 'British Conchology,' p. 246, for retaining the generic name Tectura in preference to the later and objectionable name Acmaa, although Mr. Dall and the Rev. J. E. Tenison Woods prefer to use Acmaa. Lepeta cæca, O. F. Müller. Patella cæca, O. F. Müller, Zool. Dan. Prodr. p. 237. no. 2866. BODY of a pale yellowish colour, pinkish about the head: mouth round, opening vertically: mantle thick: tentacles awlshaped, and thick: eyes none: foot oval, stout. Off Godhavn, 80 fms.; Station 1, 175 fms.; 3, 100 fms.; 5, 57 fms.; Holsteinborg, 35 fms.; St. 13, 690 fms. Circumpolar, and ranging southwards to the west coast of Scotland, Cape Cod, and North Japan, at depths of from 4 to 100 fathoms; also widely distributed in the Pliocene and newer Tertiary strata of northern regions. The apex in the young is spiral, incurved, and deciduous, and it resembles that of Propilidium; but in the latter the spire is persistent and has two turns instead of one; and L. cæca wants the internal septum. Propilidium ancyloïdes, Forbes. Patella? ancyloides, Forb. in Ann. Nat. Hist. vol. v. p. 108, pl. ii. f. 10. Station 12, 1450 fms.; one dead specimen. 'Lightning' Expedition, 189 fms.

(Acton)! It is the Rostrisepta parva of Seguenza, a Pliocene fossil of Sicily. Fissurellidæ. Puncturella profundi*, Jeffr. SHELL conical, with a roundish-oval outline, thin, semitransparent, of a dull hue: sculpture, numerous longitudinal and equal-sized striæ, and still more numerous but minute and less raised concentric striæ, the intersection of which causes a very fine and delicate cancellation and a beading of the longitudinal striæ: colour brownish-white, becoming pale yellowish in dead specimens: beak smooth, incurved and twisted to the left, forming a minute spire of one whorl and a half: slit pearshaped mouth roundish-oval: margin very finely scalloped : inside glossy and somewhat nacreous: plate or septum large, triangular, thin, placed vertically in the middle, and occupying the lower third of the inside, so as to separate the anterior from the other half; it is not a vaulted sheath as in P. noachina, nor does it cover (although it apparently protects) the slit or opening at the top. L. 0.25. B. 0.2. a Station 12, 1450 fms.; dead specimens. Porcupine 'a Expedition, 1870, coast of Portugal, 740-1095 fms. I have described the shell from a 'Porcupine' specimen. This differs from P. noachina in the size, shape, texture, sculpture, slit, and internal plate. It belongs to the genus * Inhabiting the depths of the sea. |
