vix convexiusciilo satisque declivi ; latere antico manifeste longiore ; 

 postico atteuuato, subrostrato ; extremitate autica rotundata ; pos- 

 tica angulata ; costa umbonali conspicua ; ligamento haud promi- 

 nente ; superficie interna albida aut flavida ; dentibus lateralibus 

 distinctis^ sequidistantibus. 



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

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

 foi-ming a St. Andrew^s cross upon the umbones), but usually only 

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

 lineated markings of purplish crimson, rather obliquely distinctly 

 but not coarsely concentrically grooved ; anterior side much the 

 longer, and romided at its extremity, its dorsal slope shght but 

 convex ; posterior side attenuated, the shghtly convex ventral edge 

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

 moderately sloping and scarcely convex ligamental one ; umbonal 

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

 teeth distiuct, 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, solid, convex, somewhat glossy, variable in 

 colouring being imiform wliitish or purple (both within and with- 

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

 red markings on a whitish ground; surface Math very distinct 

 concentric sulci, which become strong elevated striae as they ap- 

 proach the prominent umbonal ridge, on and beyond which they 

 become sublamellar ; the interstices traversed by nearly obsolete 

 radiating strise ; 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
