 Ilab. ? 



This is apparently a shell of immature growth, but so 

 peculiar in its colour and marking, that I venture to 

 describe it as new. Of a warm brown silken hue, painted 

 with fine sharply zigzag streaks somewhat broken, nuii>h 

 more delicate and numerous towards the ape.x. 



Species 39. (JIus. Cuming.)

The columella being very slightly truncated in this 



species, partakes very much of tlie character of H/ili/i/ia.

Ilab. Zanzibar. 



An extremely characteristic species of a pure luulbrni 

 cream colour without any indication of pattern. 



The specimen originally described, and from which the 

 accompanying figure from the Concliologia Systematica 

 was engraved, is in the possession of the llev. S. C. E. 

 Neville Rolfe of Heacham Hall. Mr. Cuming has since 

 obtained similar specimens from Zanzibar.
