 f. 11. 



In the 'Annals and Magazine of Natural History' for June, 1883 

 I indicated the probability that a species which was there described 

 and figured as a Oylichina parviila might be the type of a distinct 

 genus, intermediate between Cyliclmn and Utriculus, because the 

 spire was partly concealed ; and I suggested the name Cryptaxis. I 

 am now encouraged by the discovery of the present species to adopt 

 the above generic name. (Je^r.).

Shell solid, yellowish-white, short, broad and squarely truncate in 

 front with a rather blunt mammiform spire exhibiting about three 

 turns ; surface transversely marked with faint lines of growth, and 

 near the suture with fine well-marked wrinkles, as if too large for 

 the spire around which the posterior fourth of the whorl is closely 

 wound and very strongly appressed, giving the posterior edge of the 

 last whorl especially a bevelled appearance; spiral sculpture, 

 extremely fine grooves, not puncticnlate, strong on the posterior 

 aspect, obsolete on the body (which appears polished), and, except 

 in the young, on th,- anterior extreme; the sutural wrinkles are 

 prettily ghagreened by the intrr-ectiou of these fine close grooves; 

 ry obliquely wound, the margin of the volutions rounded 

 (notwithstanding it- I.ein.: eloM-ly appressed") and the rounded edge
