 Clanculus carinatus A. AD., P. Z. S. 1851, p. 162. 



In its conical form, densely granose-lirate sculpture and the carina 

 in the middle of the upper surface of the whorls, this form is quite 

 distinct. 



VAR CARINATUS A. Adams. PI. 14, fig. 24, 25. 



A form which differs slightly from the type in its somewhat great- 

 er altitude ; the peripheral carina of the penultimate whorl is exsert- 

 ed ; the coloration consists of short alternate crimson or brown 

 dashes below the suture, and brown tessellations on a white ground 

 in the center of the base, the intervening space unicolored, brown, 

 save the carina, which is articulated with white.
