 eously placed with Bolma. Mr. Smith's type is a young shelly 

 measuring only 31 x 27 millimetres.

In my original description of Schizodentalium plurifissura- 

 tum, I remarked that the strange feature of a series of fissures on 

 the convex side was subject to considerable variation ; the type 

 having 5 such fissures ; mention being made of one with 4, and 

 one with only 2. The South African specimens present such a 

 remarkable variation in this respect that I can no longer con- 

 sider it a generic character. Some of the shells before me, al- 

 though undoubtedly belonging to one and the same species.
