Shell about three-quarters of an inch in diameter, and is nearly 

 allied to C. gryphoides, but may be at once distinguished by 

 its having the margin crenulated, and the inner surface of the 

 valves always covered with dots, which are, however, so mi- 

 nute as to be hardly observable without a glass ; the side by 

 which the lower valve adheres to other substances, is flat. 



lamellosa. 22. Shell roundish, with transverse 

 rows of membranaceous serrated laminae, and 

 the upper valve flat.

Inhabits 



Shell about an inch in diameter, and either roundish or ob- 

 long ; it differs from C. gryphoides in the lamellated scales 

 being placed in regular transverse rows, and not imbricated ; 

 but I greatly doubt whether it has ever been found in any 

 other than a fossil state. 



punctata. 23. Shell sub-orbicular, with transverse 

 rows of rather distant scales, and the inside 

 dotted.

Inhabits the coasts of Guadaloupe. Bruguiere. 



Shell about ten lines in diameter, ventricose, nearly orbicular, 

 white and transparent ; it is nearly allied to the foregoing 

 species, from which Bruguiere says it differs in having the 

 inner surface of the valves minutely punctured, the under 

 side of the scales studded with elevated dots, and their in- 

 terstices striated.
