small contiguous teeth. Although the species and va- 

 rieties of this genu^ are but few, yet these few are thinly 

 scattered over most parts of the globe; however, some 

 coasts (the European in particular) supply a profusion, 

 but not attended by any great variety : they are mostly 

 found buried in the sand. 



The Indian, Atlantic, American, and Northern seas, 

 have also their share, and the Mediterranean is not ex- 

 empt from the general contribution. It is not exactly 

 ascertained that any of this genus are natives of rivers. 



The Donax derives its name, in all probability, from 

 its shape, which resembles the barbed head of a javelin 

 or dart.
