60 CONUS. 
An obscure species. (. suturatus, Kiener, not Reeve (fig. 70),

by a smooth olivaceous epidermis; in which state it is C. 
Gubbe, Kiener (fig. 73). 
C. contusus, Reeve. Pl. 18, fig. 74.

grooved, rude at the sutures, apex very sharp; ochraceous, 
stained with ash-blue. Length, 1°25 inches. 
Moluccas. 
Whether this species will be found to reveal any design in the 
coloring, it is impossible to foresee from the single worn 
specimen.
