A West Indian shell ; introduced hy Donovan as taken near 

 Hartlepool, on the coast of Durham. The small siyechnen, with 

 ahout fifty (!) ribs, stated in Turtons Dithyra fcoj^ied at p. 78 qf 

 the British Marine Conchology ) to have been taken alive at Liver- 

 mead, near Torquay, is evidently not this shell, and was, in all 

 probability, only the young of Venus ovata, the fry of which 

 closely resembles a small Cockle. Unfortunately, the original speci- 

 men is lost, and the description is inadequate for the determination 

 of the species. In some local collections we find Cardium pyg- 

 moeum p)reserved under this name.
