tip. The second whorl is crossed by about twelve rather prominent 

 and obtuse ribs, which are most elevated at the periphery ; their in- 

 terspaces are concave and wider than the ribs. On the last whorl, 

 which forms the greater part of the shell, there are about fourteen 

 ribs, most prominent on the shoulder, fading out a short distance 

 below the periphery, and also disappearing close to the suture ; the 

 base is somewhat produced and is destitute of sculpture. There is a 

 minute umbilical chink or groove, partially concealed by the edge of 

 the lip. The suture is strongly impressed. Aperture rather large, 

 obovate, broadly rounded posteriorly, narrowing nearly to a point 

 anteriorly, at the junction of the outer lip and columella ; the outer 

 lip is rather thin, without a varix, strongly convex at the shoulder, 

 and a little produced anteriorly, where it forms a distinct, prominent 

 angle at its junction with the columella-margin, which is straighter 

 than in most species, though somewhat excurved. In some speci- 

 mens there appears to be a rudimentary notch at tlie anterior angle 

 of the lip, somewhat like that of Trichotropis and LHiopa. The 

 inner lip is usually not continuous on the body-whorl. Color dark 

 reddish brown, varying to light brown and brownish yellow, fre- 

 quently more or less coated with iron oxide.

In color and general appearance this species resembles the young 

 of C. Jan-May eni. It is, however, a shorter and stouter species, and 

 is destitute of the spiral lines, which render the ribs on the shoulder 

 conspicuously nodulous in the latter.

Shell small, white, long-ovate, with a regularly tapering, blunt- 

 tipped spire ; a strongly impressed suture ; and four to five evenly 

 convex whorls, which are rather finely and regularly reticulated by 

 transverse ribs and revolving cinguli of nearly equal strength, except 

 on the base, which has only the spiral sculpture. Apical whorl rela- 

 tively large, obtusely rounded, nearly smooth ; on the second turn a
