 under the head of the former.

Jonas. (Hamburgh), MSS. 



Hab. Zanzibar. 



This species exhibits a curious black-spotted appearance 



from the tubercles being of a blackish brown colour within ; 



they ai-e covered by a superimposed layer of white, dm-ing 



the growth of the shell, but it becomes more or less won 



off by friction or erosion.
