" SIk'11 <iv;il, tliiii, >riiiiti\ius|);irciit, ;i!ul i^'Iossy : sculpture^ 

 very muiierous ami n-giiliir tine spiral or revolving strias, 

 which are closely punctured ; they are stronger at the base 

 than at the crown : colour white : spire deeply sunken, and 

 for the most part concealed in a small cavity in the centre of 

 the crown ; but the bulb-shaped apex is visible at the bottom 

 of the cavity: mouth seminblong, contracted above and ex- 

 ))anding belov,- : outer ///> slightly raised above the crown and 

 channelled, curved in the middle and at the base: inner lip 

 incons|)icuuus : pillar straight du the upj)er half and incurved 

 below. L. 0-2, B. O'l." 



Three specimens from ' Triton ' exped., Stat. 13, lat. 50^ 

 ol' X., long. 8^ 18' W., .")70 fathoms {'/efre?/s), and I have 

 a small specimen (L. O'l) which I found in ooze from the same 

 station. 



As far as the above description goes the shell might be a 

 Tornatina ; but the figure represents a shell nearly allied in 

 form to Scaphander and with sculpture somewhat like that of 

 S. punctostriatus. Compared with my smallest example of 

 the latter species, less than 0*2 long, my little Cryptaxis 

 differs in its mure equal breadth tliroughout, the lip being 

 more ex|)anded below and the apex at the other extremity 

 being broader, and the small S. jJunctostriatus shows no more 

 sign of perforated apex than does the adult. I have likewise 

 compared it with Cylichna insculpta, Totten, which shell is 

 more broadly ovate and has the apex closed.
