staged appearance. The last whorl shows these colored keels and also a 
group of two or three spiral threads occupying a red-brown tract around 
the columella. The axis is imperforate (Fig. 52). 
In one adult specimen, 9.2 mm. long, the keel midway between 
periphery and suture (as well as that on the periphery) remain strong to 
the end of the last whorl, and there are two distinct cords around the 
columellar region, but no colored tract there (Fig. 5la). This example 
retains early characters lost in what we select as typical C. lang?. 
In two examples the peripheral keel is reduced to a mere angle, 
which becomes obsolete on the last part of the whorl. The band of the 
upper surface extends upon the last whorl (Fig. 51d).

The shell is short; broad, narrowly umbilicate, the umbilicus bounded by a keel; 
rather solid, blackish-brown. The four whorls are strongly convex. Sculpture of 
strong, somewhat unequal spiral cords narrower than their intervals, one at the 
shoulder being slightly larger. On the last whorl there are 12 of these cords in the 
type; in the younger paratypes 10 is the usual number. The intervals have extremely 
close and fine axial striz. The aperture is large, nearly circular except for a wide angle 
above. Outer lip crenulate, thin. Columella concave, with a rather heavy blackish- © 
violet callus. Parietal callus short, rather strong. 
Length, 5.0 mm.; diameter, 4.0 mm.; length of aperture, 3 mm. 
A well-characterized species by its short, umbilicate shell.
