pointing out that while smaller, A. bandeirana has a half 

 whorl more, a vertical columella, the shell has no dark 

 markings, and the base is not granulose, as it is in A. 

 dohrniana. A. welwitschi is much more closely allied to 

 dohrniana.

This species, named for the Marquis Bandeira, has been 

 united by Dohrn with A. dohrniana Pfr., a view combatted 

 by Morelet (Journ. de Conchyl, 1873, p. 327; 1874, p. 60). 



Dautzenberg examined specimens collected in the Congo 

 valley by Dupont, typical in other respects, but measuring
