This appears to be a nondefcript fpecies, at lead we 

 have not been able to find any thing hke it defcribed : it 

 comes neareft to Donax plebeia in ftape, being fub- 

 cuneiform, and the teeth are equally ftrong in propor- 

 tion ; in thefe, however, it differs, efpecially in their ob- 

 liquity, being the reverfe of each other; that fiiell, too, 

 has a lateral tooth, and the beak turns towards the pof- 

 terior or fiiort fide ; whereas, in this, if any thing, it is 

 inclined to the Ioniser or anterior fide. 



It appears to be a rare fpecies, as only one mutilated 

 fpecimen of a fingle valve, had come under examination 

 till very lately, which was taken at Falmouth in Corn- 

 ■wall, five or fix years ago ; from which we did not 

 choofe to hazard a defcription : a few other fpecimens, 

 recently found at St. AuflLes bay in that county, and on 

 the coafl: o{ Devon, has enabled us to add it to the cata- 

 logue of Britijli Shells. They are all exaftly alike in 

 colour and markings.
