Shell imperforate, thick, conico-elongated, apex reddish, eroded, 

 remaining whorls 6, spirally lirate, penultimate whorl with 6 granose 

 lira?, the first and last largest, 6th or basal ridge very prominent 

 subcarinate, interstices obliquely striate, decussated on the last 

 whorl ; upper whorls whitish-rosy, penultimate radiately streaked 

 with white and red, last whorl olivaceous, obscurely clouded, 

 carinated ; base convex, ornamented with 7 concentric line, punctate 

 with rosy, and with intermediate lirulse ; aperture subquadrate, basal 

 margin arcuate ; columella straight, bounded outside by a parallel 

 groove, truncate at base. Alt. 11, diam. 8 mill. (Fischer.)

This species, represented by one slightly worn example, belongs 

 to the same group as the preceding \_T. giliberti]. It is heavier; its 

 base is wider ; the surface of the whorls has granulose lirse, and the 

 oblique strife, very prominent on the last whorl. The coloration is 

 peculiar. ' It is probable that this diagnosis will require modifica- 

 tion when better preserved specimens are found. (Fischer.) 



The single specimen known is in the Bordeaux Museum. 



C. FOURNTERI Crosse. PI. 45, fig. 51. 



Shell imperforate, acutely elongate-conical, small, brown or 

 olivaceous, unicolored or punctate or maculate with white ; spire 

 straightly conical, apex acute, sutures linear ; whorls about 8, flat, 

 very finely, evenly, densely spirally striate, the striaB sometimes sub- 

 decussated by delicate oblique growth-lines ; last whorl carinate at 

 periphery, the base coarsely lirate, lirse about 9 in number ; aperture 

 small, quadrangular, smooth within ; lip acute, bordered inside by 

 a wide porcellanous band, the throat nacreous, brilliant green ; col- 

 umella straight, scarcely truncate at base. 



Alt. 9, diam. 6 ; alt. 7, diam. 4? mill.

Seems to be very closely allied to C. giliberti. The figure of this 

 species is not very satisfactory.
