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

 inipobta, nlbida ; concentrice striata, striis tenuibus, confertissimis, 

 ad umboues posticeque obsoletis; linois verticalibus interruptis 

 fissurseformibus notata ; margine ventrali convexo vel subarcuato ; 

 dorsali postice subrecto (plerumque subincurvato) declivi, antic^ 

 prope umbones retuso, deinde convexo, satisque decHvi; latere 

 postico breviore, subbiangulato ; extremitate antica rotundata; 

 natibus prominentibus, acutis; ligamento maximo, promineute; 

 flexura ventrali satis distincta ; superficie interna nitida, plerumque 

 flavescente ; deutibus lateralibus magnis, antico approximato. 



Var. Obovata, extus flavescente, intus flava. 



Eounded-ovate, solid, 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 ; hgament very large, projecting; anterior side 

 romided, 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

T. testa^ T. remlei simillima, sed subobliqua et sulcis concen- 

 tricis valde irregularibus vixque continuis; natibus baud recte 

 incuryatis ; margine dorsali postice elevatiore, antice prope nates 

 prominulas subincurvato; umbouibus Isvigatis; extremitate pos- 

 tica angulata. 



Var. Testa magis compressa; sulcis concentricis baud rudibus, 

 et versus marginera ventralem solum conspicuis. 



In sculpture, colour, and general shape extremely hke Remies, 

 but appearing obhque from the beaks ha\ang a forward incbnation' 

 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.
