Subgenus Leroya Grandidier

species: L. bourguignati Grandidier and L. charmetanti Grandidier. Type: Leroya 
bourguignati Grandidier, here designated. 
E. v. Martens considered the two original species of Leroya, ES 
bourguignati and L. charmetanti to be varieties of Lanistes farlert Craven. 
Germain directly united bourguignati with farler:, and considered charme- 
tanti a variety. These conclusions were apparently not based upon the 
actual comparison of specimens. 
Both of Bourguignat’s species are described and figured as having 
the columella “robust, thick.” It passes by an even curve into the 
basal margin, exactly as in L. graueri. L. farleri has the columella only
