In this species the aperture is narrower than in P. congoensis, much 
as in P. charmesiana; the last whorl is long, as seen in front, and the 
adnate part of the inner lip‘is relatively long, thereby differing from P. 
congoensis amplior, which attains dimensions nearly as great. The 
umbilicus, while rather large, is not as open as in P. congoensis. Bands 
are faintly or not visible externally, but more or less apparent in the 
mouth. The character of the surface varies somewhat, but only one of 
the examples seen is ‘‘ obsolete cngulata’’ as the type was described. The 
lip is whitish with brown spots in some examples, the mouth more or less. 
suffused with pinkish cinnamon within.

A half grown specimen (length, 82.5 mm.; diameter, 68.0 mm.; 
aperture, 60.0 33.0 mm.) was taken somewhere on the middle Congo (the 
label destroyed). The shell is moderately umbilicate with a rather high 
spire and recalls P. ovata (Olivier) in contour. It is isabella color with 
light brownish-olive streaks, becoming brussels-brown on the last part. 
Some duskier bands are faintly visible in the lower half. Surface glossy, 
showing faint microscopic spirals on the earlier whorls. The whorls are 
not flattened below the suture. The aperture is narrow, as in P. charme- 
stana, suffused with pink inside. Columella and submargin of the lip 
nearly white. The adnate portion of the inner lip is very thin, trans- 
parent, and long, being half the length of the aperture. | 
The operculum is long, narrow, the columellar margin strongly 
sigmoid, being decidedly concave in the upper part. Interior pink,
