Test. Brit. p. 64. Penn. Brit. Zool. 1812. 4. p. 181. 



A thickish, milk-white shell, somewhat diaphanous, 

 smooth, and depressed ; margins rounded on both sides ; 

 very smooth and yellowish within ; primary tooth of the 

 hinge bifid ; lateral teeth strong, that in the right valve 

 more solid and remote than the other. Length an inch 

 and a quarter ; breadth an inch and three eighths. 



This is a very rare British shell, dredged up at Wey- 

 mouth, under the inspection of the late Duchess Dowa- 

 ger of Portland, and first described by Dr. Pulteney. 

 It does not appear to be the species figured by Lister, 

 Born, and Chemnitz, though all those authors have been 

 referred to for this shell.
