vix convexiusciilo satisque declivi ; latere antico manifest! longiore ; 

 postico attenuate, subrostrato ; extremitate autica rotundata ; pos- 

 tica angulata ; costa umboiiali conspicua ; ligamento liaud promi- 

 nente ; superfieie interna albida, aut tlavida ; dentibus lateralibus 

 distinctis, aequidistantibus. 



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

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

 forming 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 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 ligamental one ; umbonal 

 ridge blunt but conspicuous ; inside white 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.

T. testa oblongo-elongata, sohda, convexa, albida aut purpurea, 

 maculis bneisve nebulosis radiantibus fusco-purpureis rubro-roseis 

 aut fulvo-aurantiis plerumque ornata, concentrice sulcata et ob- 

 solete radiatim striata ; sulcis postice sublamellosis ; margine ven- 

 trali antice crenato, postice retuso et sursum acclinato; dorsali 

 antice vix declivi, postice subrecto subincurvato satisque declivi ; 

 latere postico manifeste breviore, rostrato; flexura costaque um- 

 bonali conspicuis ; ligamento subdepresso ; dentibus lateralibus 

 validis, subajquidistantibus. 



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

 colouring being uniform whitish or purple (both within and with- 

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

 red markings on a whitish ground; surface with 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 striae ; 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
