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.
