ever, the shells, hut the animals also are quite distinct ; the latter in Conus 

 Ceylonensis heing a bright scarlet throughout, the body minutely, almost 

 imperceptibly streaked with white, the siphon the same, only much more 

 distinctly so ; the animal of Conus pus illus is, on the other hand, pure white, 

 with a narrow pink rim round the extremity of the siphon and at its base, 

 and the posterior end of the body is also tinged with pink. 



Drillia ltjcida, n. sp., PI. VIII, Fig. 15. 



Shell acuminately fusiform, very smooth and glittering ; white, slightly 

 and irregularly marbled with pale brown here and there between the ribs and 

 especially behind the outer lip ; suture distinct, apex blunt and rounded, 

 almost like that of Pyramidella in character ; whorls 8 to 9, the two first 

 smooth and embryonal, the others divided with a deeply incised groove beneath 

 the suture, longitudinally, thickly, distantly ribbed ; last whorl with 9 ribs, 

 transversely striated at its base, gibbous posteriorly, with a rather consider- 

 able smooth space behind the marginal varix (as in Reeve's fig. 199, Pleur. 

 pudica, Hinds), next the suture the upper part of the ribs, cut off by the 

 deep spiral groove, have the appearance of a row of granules ; columella and 

 aperture smooth, a callous tubercle at junction of outer lip with the former, 

 sinus very deeply excavated.

H. and A, Adams in their ' Genera of Recent Mollusca' class Clavatula 

 quisqualis of Hinds as a Glathurella ; it would, however, probably be better 

 placed in Drillia, as is done with other allied spp. robusta, Hinds, &c. D. 

 lucida resembles extremely closely the shell from South America figured and 

 described by Hinds as Clavatula quisqualis (Voy. Sulph.,pl. VI, fig. 5) ; the 

 Indian species is smaller, with transverse striae at base of the last whorl, with 

 a row of granules and a deep groove beneath the suture, and with straight 

 instead of oblique ribs. The type is from the Persian Gulf, where it was 

 dredged rather plentifully by Mr. Blanford off Tumb Island and Gwadar ; 

 it was also dredged by Mr. Wood-Mason at the Andamans and found by 

 the late Mr. Raban at Pooree iu the Bay of Bengal ; the specimens from the 

 two last-named localities differ slightly from the type form, being a little more 

 richly marbled with brown (much as in Hinds' figure of his Clavatula Iceta), 

 and having the ribs on the last whorl a trifle more rounded and the penulti- 

 mate rib in the centre of the back more developed than the others (present- 

 ing a varicose appearance). 



Drillia acuminata, Migh., PI. VIII, Fig. 14. 



P. Bost. Soc, 1845. 



Shell fusiform, resembling in shape many small species of Mitra, some- 

 what smooth and shining, apex sharp and pointed (generally broken off) ;
