Suborbicular, solid, nearly equilateral, from convex to subventri- 

 cose, dull dii'ty M'liite, sculptured with numerous somewhat obso- 

 lete radiating costellse, which are decussated by very fine raised 

 crowded concentric strise; ventral edge arcuated; the dorsal sloping 

 from the rather prominent beaks x)n either side, and rather the more 

 convex in front ; anterior side rounded, posterior obtusely subangu- 

 lated ; ligament sunken, fold and umbonal ridge not conspicuous ; 

 inside wliite ; lateral teeth large, the front one the nearer. 



Var. Larger, wliite ; the liinder (and not as in the type,) the

T. testa obovata, subobliqua, inaequilaterali, ventricosa, solida, 

 incarnata aut albido-rosea, impolita; striis elevatis concentricis 

 tenuissimis strias radiantes elevatas confertissime decussantibus ; 

 margine ventrali arcuato, postice sursum accliviore ; dorsali antice 

 dechvi et pro])e nates paululum incurvato, postice elevatiore subar- 

 cuato et subito declivi ; latero antico longiore, rotundato ; extremi- 

 tate postica rotnndato-angulata ; ligamento angusto, parvo, infosso ; 

 natibus acutis, prominentibus ; flexura costaque umbonaH subobso-

 versus subrosea ; dentibus laterahbus maximis, subsequidistantibus. 



Obovate, rather oblique, dull, solid, ventricose, pinkish wliite, 

 or flesh-coloured, closely decussated by elevated radiating, and by 

 fine concentric lamellar striae ; ventral edge arcuated, and ascending 

 posteriorly ; anterior side the longer, its extremity rounded and 

 sHghtly attenuated, its dorsal edge sloping, and near the acute and 

 prominent beaks, somewhat incurved ; liinder extremity subangu- 

 lated, the more elevated ligamental edge sloping rather suddenly, 

 and in an arcuated Line ; bgament small, narrow, and sunken ; um- 

 bonal ridge and fold nearly obsolete ; a lanceolate lunule ; inside

In almost evcTy adult specimen the tips of the beaks are chalky 

 white, the umboncs yeUow, and the ligamental edge rosy. 



I had inadvf-rtently designated this shell with a pre-occupied 

 name.
