ochraceous. In structure, however, the male strongly 
differs in the length and shape of the opercula. In 
C. pustulata the opercula are not half the length of the 
abdomen and their inner margins strongly oblique to apices ; 
in the species here deseribed 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. pustulata the apices are obtusely 
rounded.
