T. testa, ovato-suborbicnlari, solida, convexa aut subventricosa, 

 impolita, albida ; conccntrice striata, striis tenuibus, confcrtissimis, 

 ad umbones posticeque obsoletis; lineis verticabbus interruptis 

 fissuraeformibus notata ; margine ventrab convexo vel subarcuato ; 

 dorsaH postice subrecto (plerumque subincurvato) decbvi, antice 

 prope umbones retuso, deiude convexo, satisque decbvi; latere 

 postico breviore, subbiangulato ; extremitate antica rotundata; 

 natibus prominentibus, acutis; ligamento maximo, prominente; 

 flexuia ventrali satis distincta ; superJEicie interna nitida, plerumque 

 flavescente ; dentibus lateralibus magnis, antico approximate. 



Var. Obovata, extus flavescente, intus flava. 



Rounded-ovate, solid, varying from convex to subventricose, 

 dull whitish, with vertical fissure-Hke interrupted bnes, and crowded 

 concentric fine striae, wliich latter become obsolete on the umbones 

 and posteriorly ; ventral edge varying from convex to subarcuated ; 

 beaks prominent and acute, with a forward inclination; fold 

 tolerably distinct ; bgament very large, projecting; anterior side 

 rounded, rather the longer, the dorsal edge at first sHghtly concave 

 and then convex and moderately sloping; posterior end nearly

T. testa T. remiei simillima, sed subobHqua et sulcis concen- 

 tricis valde irregularibus vixque continuis; natibus hand recte 

 incurvatis ; margine dorsali postice elevatiore, antice prope nates 

 prominulas subincurvato; umbonibus Isevigatis; extremitate pos- 

 tica angulata. 



Var. Testa magis compressa ; sulcis concentricis haud rudibus, 

 et versus marginem ventralem solum conspicuis. 



In sculpture, colour, and general shape extremely like RemieSy 

 but appearing obhque from the beaks having a forward incKnation, 

 and the anterior dorsal edge being sbghtly incurved ; posterior dor- 

 sal edge the more elevated, longer than in the last species ; pos- 

 terior extremity distinctly angulated ; ventral edge sHghtly as- 

 cending posteriorly ; beaks rather prominent.
