(Collect. Mass. Lam.) Guaurtient, pl. 44, fig. C-D. 
Pl. XXVII, fic. 112. 
B. testa ovato-acuta, crassiuscula, dorso levigati ; basi striata, cinereo- 
cerulescente, obscuré zonata ; anfractibus propé suturas tuberculatis; labro 
posticé denticulis muricato, intus striato. 
Shell ovate, inflated, smooth, polished, of a variable color, 
bluish ash, reddish or brown, covered with narrow, white, 
longitudinal lines, irregularly spread over it; a deeper zone 
surrounds the suture, and two or three others are found upon 
the lowest whirl, that of the middle much more marked, and 
sometimes the only one; spire composed of six convex whirls, 
slightly flattened at their upper part, and crowned by a row of 
rounded tubercles; the three or four upper whirls are folded 
longitudinally, and intersected by transverse strie. Aperture 
ovate, notched at the top of the right lip, with a ridge upon 
the left. The depth of the cavity is brown, and marked with 
a whitish band. Right lip thin upon the edge, crowned 
throughout its whole length with small, short, and pomted 
denticulations, furnished internally with numerous transverse 
strie ; columella arcuated, covered by the left lip which ex- 
tends upon the body of the lowest whirl in a white, rather 
thick callosity, loaded towards the base with some slightly 
apparent guttules, and terminated by small spinous points. 
Length 14 lines. Width 7 lines. 
Inhabits the seas of Madagascar, and Port Dorey, at New 
Guinea. 
This shel] has some analogy with the preceding; but several 
differences distinguish it: it is more elongated; the last two or 
three whirls are smooth, and ornamented only around the suture, 
by tubercles oftentimes rounded ; finally, the callosity upon the 
body of the lowest whirl is much less prominent.
