 acuminate, of irregular spiral increase: two first whorls minute 

 with nearly horizontal suture, the rest of the whorls well de- 

 veloped, increasing rapidly, and separated by a progressively 

 more and more rapidly descending suture. Whorls 6, slightly 

 convex, lightly flattened, notable the fourth. Outer lip convex. 

 Columellar margin very short, quite projecting, strongly trun- 

 cate. Peristome simple, acute. Length 6, diam. 2 mm.

C. belonidcea Servain. The upper whorls in this species are 

 regularly elongate-convex, with a suture which does not descend 

 much until the beginning of the last whorl, where the descent 

 rapidly increases, the suture descending very obliquely. The 

 last whorl is not rcgularh- convex, but is flattened in the upper 

 part and inflated below. The long-piriform aperture is narrow 

 above, dilated at the base; the outer margin is straight, arcuate 

 in front. The apertural convexity of the penult whorl descends 

 in nearly a straight line to the columella, which is short, 

 straight, indistinctly truncate below. Length 5.5, diam. 1.25, 

 aperture 1.75 x 1 mm.; whorls 5. 



Spain: banks of the Rivillas at Badajos.
