MOLLirSCA OF THE ' CnALLENGER ' ESPEDITIOiSr. 335 



Up thin, sharp, regularly curved, quite straight above, where it is 

 slightly and widely hollowed back on the edge, prominent and 

 patulous below, a little pinched in at the canal. Inner lip 

 scarcely convex above, and very little concave at the base of the 

 pillar, wliich is somewhat oblique and direct; there are four oblique, 

 rather strong teeth, of whicli the two in the middle are the strong- 

 est ; a very thin, narrow, definite-edged glaze extends down the 

 edge of the mouth. 11. 0'57. B. 0"3. Penultimate whorl, 

 height 0-1. Mouth, height 0-39, breadth 0-12. 



Without the auimal it is, of course, not easy to distinguish 

 between this form and Admete, but the apex is larger and the 

 pillar-teeth stronger than they are in that genus. The generic 

 features are well marked in this species, which, however, resembles 

 no other known to me.

Shell. — Long, narrow, fusiforn:i, not ribbed, finely spiralled, Avith 

 a high, narrow spire of rounded whorls, a blunt mamillary apex, a 

 contracted rounded base, prolonged into along, lop-sided, slightly 

 reversed snout. Sculpture. Longitudinals — there are none but 

 small, rude lines of growth. Spirals — there are very many small, 

 rounded, pretty equal threads parted by shallow rounded furrows 

 of about tlieir oAvn breadth ; on the snout these threads are 

 feebler, sharper, and more remote. Colour white under a thin, 

 brown, smooth, persistent epidermis; the inside of the mouth is 

 tinged with buff", which is deeper on the inner lip than elsewhere. 

 Spire very high, narrow, conical, but a little bent. Apex consists 

 of 1 to 2, large, mamillary, but cylindrical whorls. Wliorls 8 in 

 all, high, narrow, of rapid increase, convex, rounded, contracted 

 below as well as above, where they slightly lap up on the pre- 

 ceding wborl ; the last whorl is larger than all the rest, is slightly 

 tumid, rounded on the base, which is contracted, especially on 

 the left, and is produced into a very long, narrow, lop-sided 

 bent, and ^.lightly reversed snout. Suture deep, but very open.
