the others together. At the base of each whirl of the spire, is 
found a transverse band of slightly apparent, articulated black 
points. A band, more strongly marked, the points of which 
are more distinctly observable, surrounds the lower whirl of 
the body of the shell; aperture ovate, sub-dilated, smooth, 
canal short, feebly emarginated ; columella white, nearly 
straight; right lip smooth, rarely denticulated, white and 
slightly sharp. ’ 
Length 8 lines. Width 4 lines. 
Inhabits the Mediterranean, the shores of Provence, Corsi- 
ca, Sicily, and Barbary. 
The coloring of this pretty little shell is very variable. It 
sometimes happens that the transverse articulated bands do, not 
exist, or else the longitudinal waved bands are replaced by a 
very fine vermiculated net-work. It varies much less in its 
form; nevertheless. it sometimes becomes thicker; the whirls 
of the spire are then more detached, and more elongated. _

Shell small, ovate, pretty thick, reddish, smooth, shining, 
surrounded with interrupted, small, brown lines, more approx- 
imate towards the middle of the lowest whirl, and of a deeper 
color at the base; spire elongated, pointed, composed of seven 
slightly convex whirls, surrounded at their upper part by a 
white band, sprinkled with distant, brown points or spots ; 
aperture white ; the internal edge of the right lip crenulated ; 
the external part forming a smooth, thick callus, of a dull 
white, which is continued upon the base of the shell even to 
the columella, which is arcuated and folded at its base.
