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 the anterior angle 
of the lip, somewhat like that of Zrichotropis and Litiopa. 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-Mayeni. 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.

PLATE XXXII, FIGURE 11. 
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
