ocliraceous. In structure^ however, tlie male strongly 

 differs in the length and shape of the opercula. In 

 C. pnstulaia the opercula are not half the length of the 

 ahdomen and their inner margins strongly oblique to apices ; 

 in the species here described the opercula are considerably 

 longer than half the abdominal length, their inner margins 

 concave, their outer margins a little sinuate and their 

 apices subacute, in C. pustuluta the apices are obtusely 

 rounded.
