A more globose shell than C. ignobilis, with shorter spire, more 

 convex whorls and differently formed lip. 



C. IGNOBILIS Sowerby. PI. 33, fig. 65. 



Imperforate, rather solid, conical. White under a very thin light 

 buff cuticle, with two narrow chestnut bands, one above, one below 

 the periphery, and a dark columellar tract, often very small. 



Surface lightly striatulate, the earlier whorls minutely, obsoletely 

 spirally striated. 



Spire distinctly conical, the lateral slopes slightly convex. Sut- 

 ures but little impressed. Apex obtuse, but more acute than usual 

 in the present group. Whorls 5, very slightly convex, the last 

 angled at the periphery ; base rather flattened. Aperture oblique, 

 ovate ; lip expanded and reflexed, white. Columella subvertical, 

 scarcely' arcuate.

The very distinctly conical spire of this species is a notable feature. 

 The proportions of length and breadth vary considerable. The 

 banding is usually as described above, but it varies as follows : 



1. Bifasciate, the lower band wider (fig. 65.) 



2. Upper band wanting. 



3. Body-whorl not banded. 



C. BOETTGERIANA Mollendorff. Un > figured. 



Imperforate, globose-conic, rather solid, transversely striated, 

 sculptured with minute spiral lines and forward-descending fold- 

 like wrinkles; white, covered with an olive-buff shining deciduous 

 cuticle, and encircled by two rather wide bands. Spire high conic, 

 the apex rather obtuse. Whorls 5 J, slightly convex, the last a little 

 descending, sometimes ornamented with a third band around the 

 columella ; suture broadly margined, white, opaque, crenulated. 

 Aperture oblique, ample, lunate-oval ; peristome white-lipped,
