 last whorl subangulate, with 7 to 8 shallow transverse sulci ; base 

 with about 8 sulci; aperture rhombic; columella with an acute

Probably a synonym of C. striattnn, or at most a mere variety. 



C. TUERicuj.uM Philip])i. PI. 18, fig. 9. 



Shell turreted, imperforate, transversely cingulate, dark rosy, 

 flammulate with scarlet ; whorls plane, divided by profound sutures, 

 the hist angulate ; transverse cinguli 5, equaling the obliquely 

 striate interstices ; aperture rhombic ; columella straight, cylindrical 

 entire. {Phil.) 



This species is very distinct in its size and steepledike form. The 

 shell is pretty solid, consists of 7-8 flat whorls, separated by a deep 

 suture ; they have 5 little-elevated transverse cinguli, which, upon 

 the last whorl are split into two by an impressed line. The inter- 

 stices, wide as the cinguli, are prettily sculptured by the strite of in- 

 crement. On the base I count 6 concentric line. The aperture is 

 rhombic, columella straight, cylindrical, with no tooth below. Color 

 dark rose-red, with bright red flames. 



Alt. 7, diam. 4 mill. {Phil.) 



Habitat unknown.

Is it a synonym of C. exasperatum. Pennant ? 



C. UNiDENTATUM Pliilippi. PL 17, figs. 13, 14 (enlarged). 



Shell small, elongate-conical, imperforate, rather solid; ground- 

 color white, with a more or less ])ink tinge on the up])er ])art of each 

 whorl, especially on the upper part of the spire, or sometimes yellow 

 or gray in place of pink ; entire surface longitudinally marked with 

 distinct narrow black lines. Surface lusterless, densely spirally 

 lirate and striate, the principal ridges subgranose, interstices densely 

 obliquely crispate-striate ; periphery generally scalloped or sub- 

 nodose, angular; base flat, finely or obsoletely lirulate ; whorls 

 about 10, the apical ones rosy, the rest concave below the sutures;
