A whitish, or yellowish shell, formed of three un- 

 equal planes ; the anterior face is raised in the middle, 

 so as to form an obtuse angle ; the two posterior faces 

 are round, and their edges describe the segment of a 

 circle. It has on each valve, about twenty-three convex, 

 longitudinal ribs, eleven of which, on the anterior face, 

 are partly covered with little rough scales, the upper 

 part of the shell being smooth ; the scales on the pos- 

 terior face are farther apart, thicker, and more promi- 

 nent, but not so numerous as those before ; the margins 

 of the valves are crenated ; the anterior margin is deeply 

 serrated, and does not shut so close as the rest of the 

 shell ; the summits are conic, slightly oblique, and sepa- 

 rated from each other by a thread line. The inside is 

 white, with a yellow, or orange band, extending from 

 the summit to the middle of the cavity; there are five 

 teeth in each valve, two at the beak, two lateral, and 

 one long and conical, just before the ligament ; all these 

 teeth are articulated into corresponding cavities in the 

 opposite valve. 



Inhabits the Indian seas, and, according to Linnaeus, 

 is sometimes found in the American ocean.
