The shell is shortly rimate, cylindric-fusiform, rather solid, 

 carob-brown, with an irregular cinnamon band behind the 

 peristoine and on the base; penult and last whorl flattened, 

 tapering downwards, furrowed above the rounded, projecting 

 base. Spire stout, convexly conic, not paler. Whorls con- 

 vex. Sculpture of fine oblique striae. The aperture is much 

 longer than wide, subtriangular, being narrowed below, 

 rounded basally, tawny within, armed with 7 (or 8) white 

 lamellae and plicae : angular lamella low, rather long, extend- 

 ing a little beyond the outer end of the parietal, which is 

 stronger ; columellar lamella horizontal, strong, not emerging, 

 curving upward deep within ; the subcolumellar lamella ob- 

 tuse, tuberculiform, tinted, not visible in a direct front view. 

 Three subequal plicae are evenly spaced, the upper palatal 

 reaching to the peristome, the others shorter; they show as 

 white or whitish streaks outside (and there is sometimes a 

 minute, immersed, suprapalatal fold). The columellar lip is 

 dilated, peristome otherwise unexpanded, with a thin, blunt 

 edge ; but it is rather strongly thickened a little distance within 

 the palate. 



Length 5.5, diani. 2.1 mm.; 6i/> whorls (fig. 3). 



Length 5, diam. 2.1 mm.

This form differs from the unfigured C. kobelti West., from 

 further west in northern Spain, by having a well-developed 

 subcolumellar lamella, which, however, is immersed and 

 scarcely visible in a front view. I have not seen C. kobelti.
