Spire conic, obtuse ; apex nude, rufous ; whorls 6, scarcely con- 

 vex, the last slightly shorter than the spire, subangulated ; colu- 

 mella somewhat twisted, longitudinally biangulate, entering. Aper- 

 ture oblong-subpyriform, whitish within ; peristome thin, narrowly 

 expanded, the right margin dilated above and below, basal margin 

 forming an obsolete angle with the columella. (P/V.) 



Alt. 52, diam. 25 ; aperture alt. 7, width 15 mill.

C. CARIXATA Lea. PI. 13. figs. 53, 54. 



Imperforate, elongated, the spire turrited-conic, the body whorl 

 carinated. Tawny-brown, darker below, fading to a light brown on 

 the spire, the apical whorls a trifle darker ; usually in part or 

 almost entirely denuded of the thin creamy-brown hydrophanous 

 cuticle which is disposed in ragged oblique streaks. 



Spire long, straight-sided, the earlier two whorls forming a some- 

 what bulbous apex. Whorls 7 to 7}, the first two convex, the rest 

 flat, the last whorl angular at the periphery, somewhat swollen 

 above and frequently subaugular there also. Aperture oblique, 

 broad below 7 , white or livid inside ; peristome dark brown, expanded, 

 receding below ; columella long, white, straight, somewhat receding. 



Alt. 64, diam. 29 ; oblique alt. of apert. 31 mill.

The priority of Lea's name carinatus over that given by Brod- 

 erip, dactylus, cannot be questioned. I have examined Lea's type, 

 a large and finely developed specimen.
