Distinct by its narrow, lengthened shape and beautifully 

 clear-cut granulation. The large apex and irregular mark- 

 ings are also characteristic.

The shell is lengthened, turrite, and consists of 7^ whorls. 

 The apex (embryonal whorl) is not pointed, but rounded, and 

 is formed of l 1 /^ smooth whorls; regularly spirally striate 

 whorls follow. In regular spiral series are arranged granules^ 

 which increase in size with the enlargement of the whorl, but 

 on the last whorl cease at about the middle. The marking 

 consists of brown streaks or lengthened spots in a longitudinal 

 direction, on the last 3 or 4 whorls. These streaks are broader 

 near the suture below, running to a point above. Length 40, 

 diam. 19, aperture 19 x 10.5 mm. (Sturany}.

Very closely related to C. semidecussata, from which it is 

 separable chiefly by the smaller size.

Shell subfusiform-turrite, thin; longitudinally closely pli- 

 cate-striate ; white, covered with a tawny, scaly cuticle. Spire 

 turrite, nude above, obtuse, the suture shallow, densely crenu- 

 lated, whorls 8, rather flattened, the last a little shorter than 

 the spire, somewhat tapering basally. Columella arcuate, 

 somewhat twisted, transversely truncate. Aperture little 

 oblique, acuminate-oval, whitish within ; peristome simple, the 

 right margin lightly arcuate. Length 75, diam. 31, aperture 

 38x17 mm. (P/V.).
