Hah. — Kalingwisi River, Lake Mweru. 



Rather like V. capillata, Frauenfeld, from Lake Nyassa, but darker- 

 coloured, not umbilicated, with the whorls more distinctly keeled or 

 angled, and with more distinct spiral striae. The angulation a little 

 below the suture gives the spire a turreted appearance. Of the two 

 keels upon the middle of the body- whorl the lower one is peripheral 

 and the upper one falls above the suture on the penultimate whorl.

Hah. — Kalingwisi River, Lake Mweru. 



It is one of the blackish lines around the periphery that usually 

 forms a slight carination. The species is larger than C. Morelli of 

 Preston, is imperforate, and has a larger aperture. Some examples 

 exhibit more or less spiral striation.
