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

 impohta, albida ; concentrice striata, striis tenuibus, confertissimis, 

 ad umbones posticeque obsoletis ; lineis verticalibus interrupts 

 fissurajformibns notata, ; margine ventrali convexo vel subarcuato ; 

 dorsab postice subrecto (plerumque subincurvato) declivi, antice 

 prope umbones retuso, deinde convexo, satisque decbvi ; latere 

 postico breviore, subbiangulato ; extremitate antica rotundata; 

 uatibus promincntibus, acutis; ligamento maximo, prominente; 

 rlexura ventrali satis distincta ; superficie interna nitida, plerumque 

 flavescente ; dentibus lateralibus magnis, antico approximato. 



Var. Obovata, extus flavescente, intus flava. 



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

 dull whitish, with vertical fissure-like interrupted lines, and crowded 

 concentric fine stria?, which 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 slightly concave 

 and then convex and moderately sloping; posterior end nearly 

 biangulated, the dorsal edge nearly straight (usually incurved) 

 and rather strongly sloping; inside glossy, white, or tinged with 

 yellow ; lateral teeth large, anterior approximate. 



Var. Obovate, yellowish ; within deep yellow.

T. testa T. remiei sirmlh'ma, sed subobliqua et sulcis concen- 

 tricis valde irregularibus vixque continuis; natibus haud recte 

 incurvatis ; margine dorsali postice elevatiore, antice prope nates 

 prominulas subincurvato; umbonibus hevigatis; 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 Remies, 

 but appearing oblique from the beaks having a forward inclination, 

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

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

 terior extremity distinctly angulated ; ventral edge slightly as- 

 cending posteriorly ; beaks rather prominent.
