Hab. ? 



The habitat of this characteristic species, which is at 

 present unique, in the collection of Jlr. Cuming, is un- 

 known, but it is here aiTauged with the largo Jamaica 

 Jlelicea, because it partakes in some degree of the typical 

 form of II. ingent and its congeners.

The Up and aperture of this ancient species are more 

 frequently white, than of the dark Uvid-blue colour repre- 

 sented in the accompanying figure.

Scarcely distinguished from //. Bainbridgei, except in 

 bciug of a more globosely convoluted form.

This sj)ecics approximates to the //. acuta type, and 

 partakes of the same gnmulatcd sculpture and tone of 

 colouring.
