the dorsal triangles are perfectly smoofli, but the marginal

 Inhabits the West Indian Seas, and the coasts of St. Croix and 



St. Thomas. Chemnitz. 

 Shell an inch and a half or near two inches long, and about 

 two-thirds as broad, but it is said to vary considerably in 

 breadth as well as in the convexity, colour, and markings : 

 the markings consist of bands, streaks, or veins, which some-

 dark brown colour on a paler ground ; the border is tumid, 

 scaly, and coloured alternately with large steel blue and 

 blackish spots. It may be distinguished from C.fasciatus, 

 which it most resembles, by the valves being entirely destitute 

 of granules. 



maculatus. 9. Shell with eight smooth valves, 

 spotted with brown, and marked with two 

 darker bands along the back ; margin scaly.
