Stanleyville (Lang and Chapin Coll.; March, 1915). 
The shell is imperforate, rather broad and short, the aperture more than half the 
total length; somewhat biconic, being typically carinate at the periphery; between — 
old gold and primuline yellow, the earlier whorls narrowly banded with reddish brown 
next to the suture, above and below, and in the median keel; these bands not extend- 
ing upon the last whorl. Nearly three moderately convex whorls remain in the type, 
less than two in some adult shells. The penult and earlier ones have a keel in the 
middle, another partly concealed in the suture. The surface is rather glossy, marked 
with light growth lines. The aperture is large, ovate; outer lip thin; the concave 
columella rather heavily calloused; parietal callus very thin, transparent. There is 
a slight basal projection at the junction of the columellar and external margins. 
Length, 8.3 mm.; diameter, 6 mm.; length of aperture, 5.5 mm.; nearly three 
whorls remaining. Type. Fig. 5lc. 
While this species has some resemblance to C. pirothi Jickeli, C. 
mweruensis E. A. Smith, and other carinate species, it differs by the short 
but broad shape and the complete closure of the umbilicus. 
A young shell, 4.7 mm. long, has 4% whorls. The first two are 
strongly convex; a vertical ripple or two then mark the end,of the em- 
bryonic stage, after which a median red-brown keel and one immediately 
above the suture begin, at first weakly, soon stronger. The spire has a
