Elongated oblong, moderately strong, opaque, decidedly convex, 

 but depressed near the umbones, not lustrous, almost smooth, 

 scarcely inequilateral. Surface covered, when fresh, with a dull 

 asparagus-green coloured epidermis, which rarely extends to the 

 umbones, and is more or less coarsely wrinkled at the sides ; 

 beneath this, the valves are stained with lighter and darker 

 shades of liquorice brown, and not unfrequently marked near the 

 middle with perpendicular, scattered, scratch like lines. Ventral 

 margin subparallel to the dorsal, but retuse or incurved ; dorsal 

 edges nearly straight, scarcely declining, the front one the more 

 elevated, and if anything slightly convex, the hinder just retuse. 

 Anterior side the longer, occupying nearly three-fifths of the 

 entire length ; its extremity bluntly subangulated, projecting 

 above, very obliquely rounded below ; posterior termination most 

 bluntly subbiangulated, and rather the more projecting (as usual) 

 below. Inside white ; two erect curved simple primary teeth 

 (of which the hinder is the broader) in the right valve ; two 

 smaller oblique incurved ones in the left. Length 3 inches, 

 breadth 1 inch and an ^. N. America, W. Indies, dx. Intro- 

 duced by Dr. Turton, as from the Scilly Isles,
