This form is very mutable in color, and numerous varieties have 

 been proposed. The following are the more prominent. 



Var. vlolacea Risso (j)l. 65, fig. 88), a beautiful purple form. 

 Var. ca)tdida Briis., pure white. Var. olivaceocoiwi)lor Req., uniform 

 olivaceous without flames or blotches, from the Gulf of Gabes.. Var. 

 seriopiuictata Ren., dark olive, uniform or mottled with lighter, the 

 periphery and supra-sutural fasciole conspicuously articulated with 

 olive-brown and white. 



Var. SOLIDUM Phil. 



Shell conical, imperforate solid, pale olivaceous, articulated with 

 yellowish ; whorls ])lane, base nnii'gined by a prominent cingulus ; 

 whorls sculptured with 3 slightly elevated cinguli, the last rounded- 

 angular; base obsoletely 7 to 9 ciugulate ; aperture rhondioidal, 

 columella very oblique, entire. Alt. 14, diam. 12 mill. (Phil.) 



This form I place here with some doubt on account of its more 

 oblique columella, which forms no angle where it joins the basal lip. 

 It may be a synonym of C. coimlam, ov possibly distinct. 



C. occiDENTALis Mighels & Adams. PI. 37, figs. 2, 3. 



Shell rather small, thin, imperforate, opalescent; surface shining, 

 strongly sculptured above with smooth, yellowish sj^iral ribs, narrower 

 than their interstices, numbering 3 or 4 on each whorl ; periphery 

 very bluntly subangular, base nearly flat, with a few ribs around 

 the axis and at periphery, otherwise smooth. The spire is elevated, 

 acute ; whorls 7 to 8 ; apical whorl minute, smooth, rounded ; follow- 

 ing three whorls beaded on the spiral ribs ; sutures impressed ; aper- 

 ture rather rounded, pearly; columella, arcuate, narrow, not dentate 

 or truncate at base. Alt. 12, diam. 10-11 mill.
