 This shell has somewhat the aspect of the Triton cynocephahs ; it 

 diflFers in being much less ventricose, and in having very prominent 

 tubercles round the upper part of the whorls. The mouth is stained 

 with a pale flesh-tint \vithout any indication of dark colour on the 

 columella.

The longitudinal waved ridges •which adom the surface of this 

 interesting species have, in the fine specimen before me, a beautiful 

 ripple-like appearance which is very characteristic. The columella 

 and interior are covered with enamel of a bright uniform flesh-tint, 

 and the A-arices are very round and prominent. I have seen several 

 exaraples of this species in difFerent stages of grow'th, all exhibiting 

 the above peculiarities ■vvith remarkable specific distinctness.

This is a strongly marked species, with the denticulated sculpture 

 of the lip extending into the aperture after the manner of ribs ; and 

 the body of the shell is crossed by flattened ridges, between each of 

 ■vvhich are three very characteristic raised lines.
