B, testa ovato-oblonga, crassiuscula, levissimd, alba ; anfractibus con- 
vexo-planis, connatis ; labri limbo striato. 
Shell ovate, oblong, thick and smooth ; the external surface 
is entirely white or ash colored, polished, covered with a thick 
reddish brown epidermis. Spire composed of six or seven 
slightly elongated whirls, somewhat convex, and united by a 
very fine, regular, linear suture. Aperture ovate, terminated 
at the base by a shallow emargination. Right lip simple, 
sharp-edged, expanded, furnished with fine transverse striz in- 
ternally : left lip smooth, arcuated lengthwise, and partially 
covering the columella. 
Length 8 lines. Width 42 lines. 
Inhabits the coasts of Brazil in the Bay of Rio Janeiro. 
This species is remarkable for its dilated aperture, and for the 
reflection of its right lip, which gives it some affinity to the 
genus Pranaxts. Wood, in his catalogue, has called it Bucct- 
num levigatum.
