Oblong, solid, convex, but slightly glossy, inequilateral, whitish, 

 with (in tlie typical variety) two deep crimson short rays (thus 

 forming a St. Andrew's cross upon the mnbones), but usually oidy 

 adorned with more or less interrupted rays of tawny-orange or faint 

 lineated markings of pm-plisli crimson, rather obliquely distinctly 

 but not coarsely concentrically grooved ; anterior side much tlie 

 longer, and rounded at its extremity, its dorsal slope slight but 

 convex ; posterior side attenuated, the slightly convex ventral edge 

 rising on that side, so as to form a beak in its junction with the 

 moderately sloping and scarcely convex Hgamental one ; umbonal 

 ridge bkmt but conspicuous ; inside wliite or yellowish, the lateral 

 teeth distinct, and equidistant. The typical variety is extremely 

 rare, I have only seen two specimens in the collection of "William 

 Walton, Esq., and the original one in the French Museum.

Elongated-oblong, sohd, convex, somewhat glossy, variable in 

 coloming being uniform wliitish or purple (both witliin and with- 

 out), but more conunonly subradiated by purplish brown or rosy- 

 red markings on a whitish ground; surface with very distinct 

 concentric sulci, wliich become strong elevated strise as they ap- 

 proach the prominent mnbonal ridge, on and beyond wdiich they 

 become sublamellar ; the interstices traversed by nearly obsolete 

 radiating strife ; ventral edge swelling out in front and sloping 

 upwards behind, so as to render the narrow and biangulated pos- 

 terior extremity rostrated ; anterior side decidedly the longer, its 

 extremity rounded, its slope very slight ; ligamental edge straightish
