168 COCHLOSTYLA-TRACHYSTYLA. 



Differs from C. cryptica in the absence or obsolescence of oblique 

 wrinkles, and in the broad band just above the periphery, denuded 

 of hydrophanous cuticle. 



Var. CRETATA Broderip. PI. 51, fig. 12. 



Shell subglobose, swollen ; whorls 3, the last much the largest, and 

 begirt with blackish bands and lines ; closely striated with oblique 

 growth-lines, and encircled with elevated spiral lines ; brownish- 

 black, with a chalky cuticle ; aperture silvery-bluish, the lip having 

 an obscure reddish border. (Brod.)

Seems to differ mainly in the more conspicuous development of 

 the hydrophanous cuticle. 



C. PANAENSIS Semper. Unfigured. 



Imperforate, turbinate-globose, solid, purple-brown, margined 

 with tawny at the suture ; spire elevated, globose ; whorls 4, a little 

 convex, encircled by evanescent impressed lines ; the last whorl not 

 descending; suture generally impressed ; columella very much dilated, 

 excavated, rather sloping, whitish-rosy ; aperture ample, subtetrago- 

 nal, livid ; peristome broadly expanded and reflexed, horny-livid, 

 upper margin strongly arched, basal margin forming an angle with 

 the ctlumella, (&) Alt. 50, greater diam. 65, lesser 46 mill.

C. panaensis SEMP., Reis., p. 189. 



The very obliquely placed aperture, with the upper lip strongly 

 arched forward, the high, globular form of the shell, the quite im-

 this as a species. 



C. CINERACEA Semper. PL 59, fig. 3. 



Depressed, solid, rough, and grooved by irregular impressed lines ; 

 ashen ; obtusely cariuated at the periphery ; spire shortly conoid ; 

 whorls 4, a little convex, the last one nearly flat above, very con- 

 vex below, not descending in front. Columella white, nearly 

 straight. Aperture oblique, subtetragonal, livid within ; peristome
