We have changed the name by which this species is or- 

 dinarily designated, in consequence of a careful examina- 

 tion of the original type of Linnaeus, which is still preserved 

 in his cabinet at Soho Square. The shape is oblong oval, 

 the texture rather thin, or but moderately strong, and not 

 quite opaque. The valves are almost equilateral, com- 

 pressed, and of a more or less glossy pale orange, or reddish 

 flesh- col our, (the latter hue is extremely rare in British cx- 

 amj)les, but is the ordinary tint of the Mediterranean spe- 

 cimens, which are much more delicate and lustrous than 

 our own,) with two whitish or paler approximate linear 

 rays, adjacent to the umbonal fold, which latter, as well as 

 the ventral flexure, is well marked. These rays are most 

 evident in the younger shells, and become occasionally in- 

 distinct in the more aged examples. The right valve is 

 closely striolated in a concentric direction ; the left valve is 

 comparatively smooth, though concentric subimbricated
