Allied to B. inter stinctua, from the same region, but much 

 smaller, shorter in proportion, and rather remarkable for the 

 mottling of colors, which causes it to look as if mouldy.

From several similar African shells, this differs in having but 

 two bands, the posterior one fairly entering the aperture so as 

 not to appear at the suture on the other whorls as in B. neuricus, 

 meridionalis, and Bengalensis, from the latter of which it can 

 scarcely be distinguished, except by this peculiarity. Both bands 

 are often wanting.

Closely allied to A. purpurea^ but the form is constantly more 

 ventricose, and by comparing an extensive series, including the 

 young, the difference is plainly not accidental. The color is 

 more mixed with green and less conspicuously flammulated, and 

 often flecked with triangular pale spots, and the aperture more 

 of a blood red. Dr. Perkins says it is only found in the interior, 

 while A. purpurea is found near the sea.
