 Barber). In coll. E. L. Layard. 



A small delicate shell, of succinoid character and nearly 

 allied to B. Bovokeri^ Sow., but differing in its fewer whorls, 

 broader last whorl, coarser longitudinal liration, and in the 

 absence of any granular sculpture.

A. testa obesa, tumida, semipellucida, tenui, cinuamomeo-ochracea ;

A handsome species, obese, of a cinnamon horn-colour, with 

 darker brown longitudinal flames irregularly disposed. 



Two fresh specimens and two dead ; the latter are smaller, 

 but undoubtedly the same species.

-4. testa oblonga, compacta, nitida ; anfractibus septem, tumidis, 

 ventricosis, undique laevibus, planatis, specimine altero olivacea, 

 fere unicolore, altero longitudiualiter flammis zebrinis decorato ;

 Bai-her, nee Bowker). In coll. E. L. Layard. 



As Mr. Layard observes, this form would appear to be one 

 of the links in the chain of Achatince which inhabit the tropical 

 and subtropical African regions. The present species is 

 meanwhile well characterized by the remarkably ventricose 

 growth of the whorls.
