 tint either uniform, or banded, or reticulated with the

 spirally striolate. Whorls about five, those of the spire 

 convex ; the first two or three extremely small, the penult 

 very large in proportion to them ; the body rounded, and 

 occupying from two-thirds to three-fourths of the entire 

 length, its basal declination not at all angulated, but 

 abruptly though arcuatedly sloping. Suture very narrow.

 chocolate-brown, broadly rounded below. Outer lip very
