Holotype, M. C. Z. no. 53185 

 Paratype, M. C. Z. no. 53186 



Holotype. — M. C. Z. no. 53185; collected Feb. 1923, at Madazini, Tanganyika 

 Territory, Africa, by Arthur Loveridge. 



Paratype. — M. C. Z. no. 53186; collected Feb. 1923, at Itende, Tanganyika 

 Territory, Africa, by Arthur Loveridge. 



Remarks. — From the shell characters it seems well to place 

 this species next to Achatina immaculata Lam. Neither the 

 radula nor the soft parts have been available for examination, 

 so that this designation remains somewhat tentative. Only 

 two specimens are at hand, and the most adult one from Mada- 

 zini is chosen as the holotype. The second specimen belongs to 

 the same series of material collected by Mr. Loveridge, and 

 since it comes from the same region as the holotype it is con- 

 sidered as a paratype.
