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

 cose, dull dirty white, sculptured with numerous somewhat obso- 

 lete radiating costellse, which are decussated by very fine raised 

 crowded concentric strife ; ventral edge arcuated ; the dorsal sloping 

 from the rather prominent beaks on 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 white ; lateral teeth large, the front one the nearer. 



Var. Larger, white; the hinder (and not as in the type,) the 

 front), dorsal edge the more elevated; the strife more elevated and 

 rather more distant.

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

 incarnata aut albido-rosea, impohta; striis elevatis concentricis 

 tenuissimis strias radiantes elevatas confertissime decussantibus ; 

 margine ventrali arcuato, postice sursum accliviore ; dorsali antice 

 declivi et prope nates paululmn incurvato, postice elevatiore subar- 

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

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

 natibus acutis, prominentibus ; ficxura costaque umbonaH subobso- 

 letis ; lunula lanceolata ; supcrficie interna tlavescente, margines 

 versus subrosea ; dentibus laterahbus maximis, subajquidistantibus. 



Obovate, rather obhque, dull, solid, ventricose, pinkish white, 

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

 fine concentric lamellar strias ; ventral edge arcuated, and ascending 

 posteriorly ; anterior side the longer, its extremity rounded and 

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

 prominent beaks, somewhat incurved ; hinder extremity subangu- 

 lated, the more elevated Hgamental edge sloping rather suddenly, 

 and in an arcuated line ; ligament small, narrow, and sunken ; um- 

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

 yellowish, pink near the margins; lateral teeth very large and 

 nearly equidistant. 



San Nicolas, Zebu. 



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

 white, the umbones yellow, and the Hgamental edge rosy. 



I had inadvertently designated this shell with a pre-occupied 

 name.
