Show 1884.] 'LIGHTNING'AND 'PORCUPINE'EXPEDITIONS. 369 Fossil. Pliocene : Messina (Seguenza). Although this shell is thick and strong for its size, it is so transparent that the eyes of the animal are clearly seen through a living specimen. In this specimen the two uppermost whorls are quite empty, and the end of the liver appears in the succeeding whorl; it probably arose from shrinking of the animal before death. 10. EULIMA FUSCO-APICATA1, Jeffreys. (Plate XXVIII. fig. 5.) S H E L L spike-shaped, slender, thin, transparent, and very glossy : sculpture, indistinct but exceedingly fine longitudinal lines, which are detected only by the microscope ; the periphery is slightly keeled in some specimens : colour that of clear glass, except the 3 or 4 topmost whorls, which are chestnut-brown: spire long and finely tapering to a point : whorls 9-11, rather convex ; the last occupies about half the shell: suture shallow, and somewhat oblique : mouth longish-oval, considerably expanding, acutangular above and obtus-angular below ; its length is nearly one third of that of the spire : outer lip remarkably flexuous and thin: inner lip adhering to the upper part of the pillar, and reflected a little on its lower part. L. 02. B. 0*075. 'Porcupine' Exp. 1870 : Atl. St. 16, 17, 17 a. A fragment of this species indicates a larger size than that which is given in the description. The dark colour of the apical whorls is very peculiar and characteristic. Distribution. Bay of Biscay (' Travailleur' Exp.). Off the west coast of Africa and Cape de Verd Isles; 681-1192 fms. 11. EULIMA PIRIFORMIS, Brugnone. (Plate XXVIII. fig. 6.) E. piriformis, Brugn. Misc. Mai. 1873, p. 7. f. 5. ' Porcupine' Exp. 1870 : Atl. St. 3 a, 6 (var. bizonata), 16, 17, 17 a. Med.. Adventure Bank. Some of the specimens are more or less curved or twisted, like E. distorta. The variety bizonata, of which a single specimen occurred, has two narrow bands of reddish-brown (one below the suture, and the other encircling the periphery) on the last whorl, and two in corresponding positions on each of the other whorls. In some of the other specimens the apical whorls are coloured as in E. fusco-apicata; but the shape of the shell and the proportionate size of the last whorl are different. Possibly, however, both of these species may be one and the same. Distribution. Bay of Biscay (' Travailleur ' Exp. 1880 and 1881), Sicily (Brugnone and Monterosato), off west coast of Africa (' Talisman' Exp.), Culebra I. ('Challenger ' Exp.) ; 11-1512 fms. Fossil. Pliocene : Ficarazzi (Brugnone). The figure given by the lamented author represented a fossil and not a good or characteristic specimen. I have therefore considered it advisable to figure a recent specimen. The Rev. R. Boog Watson has described this species from the ' Challenger' Expedition as E. chaunax, and perhaps also as E. Mans. It may be distinguished from any of its congeners by the swollen 1 Tipped with chestnut-brown. |
