 Inhabits the Asiatic Ocean. Linnaus. Coasts of Surat, and 



also Jamaica and Barbadoes. Solander. 

 Shell varying from an inch and a half, to three inches and three- 

 quarters long, and nearly equally broad; slightly inflected 

 and angular at the anterior end, and every where covered 

 with erect moon-shaped scales, which are minute about the 

 apex, and become gradually larger towards the margin ; the 

 colour is white, and generally marked with a few scattered 

 brown or ferruginous spots ; the hinge is central, and has a 

 bifid primary tooth in each valve, with strong prominent 

 lateral teeth. The length and breadth are very nearly or 

 quite equal in the shells which come from the Eastern Seas ; 

 but in those from the West Indies, the latter exceeds the 

 former about one eighth, and I have reason to believe that at 

 one time Dr. Solander had described this Western variety as 

 a distinct species, with the name of T. radula, and that he 

 ■ afterwards changed his opinion.
