which is often tinged with yellow and rarely with rose-colour at 

 the margins, concentrically siibstriated; the ventral edge nearly 

 straight, and usually very indistinctly inflated behind; anterior

Very like Timorensis, but not so elongated; the dorsal edges 

 much more sloping, and the front one not refuse. 



This may eventually prove but a young variety of Simiata, but 

 the only specimen I have ever seen (purchased ^vith tliis name 

 attached, and now in the collection of Mr. Cuming) has been pro- 

 nounced distinct by every Conchologist who has inspected it.
