 Hab, Capengo, "West Africa {Coll. H. Adams). 

 Tbis fine species most nearly approaches V.flemingii, Pfr., from 

 India; but tlie aperture is more ample and depressed, the right margin 

 more dilated, the last whorl more compressed at the j'eriphery, the 

 spiral lines on thewhorls are absent,and the colour of the upper portion 

 is red-brown instead of olivaceous. It differs from the other large 

 African species, V. soxoerbyana, Pfr., in the last whorl being less an- 

 gulate, in the spire being considerably more raised, and in the aper- 

 ture being less oblong.
