34C) LIEUT. -COL. H. H. GODWIN- AUSTEN ON [JuilC IS, 



Operculum lioniy, multispiral, black-br )wn, with a pale centre, 

 with a central minute lioUow showing dark upon it, like the bull's eye 

 of a target. 



Hab. Bu«an Hills (A. Everett). 



I place this species in the genus Jerdonia with doubt, the ojier- 

 culum of the S. Indian shell /. trochlea being of a decidedly cal- 

 careous nature ; but unless the animal differs in other resftects, it is 

 not desirable to create a new genus only on the single character of 

 the operculum.

This figure is not sufficiently good for the identification of the 

 species, and I have therefore given an enlarged drawing taken from 

 a typical specimen in the British Museum.
