Fossil. Pliocene : Messina {Seguenza). 



Although this shell is thick and strong for its size, it is so trans- 

 parent 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 

 prohahly arose from shrinking of the animal hefore death. 



v 10. Eulima fusco-apicata 1 , Jeffreys. (Plate XXVIII. fig. 5.) 

 Shell 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 top- 

 most 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. 18/0 : 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 ; 681-1 192 fms. 



11. Eulima piriformis, Brugnone. (Plate XXVIII. fig. 6.) 



E. piriformis, Brugn. Misc. Mai. 1873, p. 7. f. 5. 



8 Porcupine ' Exp. 1870 : Atl. St. 3 a, 6 (var. bizonata), 16, 17, 

 17«. 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 (' Talis- 

 man' 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 

 1 Challenger ' Expedition as E. chaunax, and perhaps also as E. hians. 



It may be distinguished from any of its congeners by the swollen 

 1 Tipped with chestnut-brown.
