Shell large, orbicular, elongated oval, globose, longer than wide, 

 thick, rounded laterally, less so in front. Dorsal valve uniformly 

 convex or slightly depressed at or close to the frontal margin. Ventral 

 valve deeper and a little more convex than the dorsal one, and slightly 

 longitudinally carinated ; beak rather sharply incurved, overlying 

 the umbo of the opposite valve, and truncated by a small circular 

 foramen, separated from the hinge-line by a wide, narrow, concave 

 deltidium in two pieces ; beak-ridges very sharply denned. Surface 

 smooth, marked by concentric lines of growth, punctate. Colour 

 pinkish-red or yellowish-horny. Loop simple, long, and reflected ; 

 cardinal process rather large and prominent ; under it a mesial septum 

 extends to about one-third of the length of the valve on either side 

 the adductor and other muscular scars. (Davidson.) 



Length, 55 mm. ; breadth, 48-7 mm. ; depth, 31-8 mm.

 depression. Ventral valve deeper and more convex than the opposite 

 one, with a longitudinal mesial fold of moderate breadth and elevation, 

 somewhat flattened, extending from the beak to the front ; margins
