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

 the margins, concentrically substriated; the ventral edge nearly 

 straight, and usually very indistinctly inflated behind ; anterior 

 side slightly the shorter, rounded at the extremity ; posterior side 

 rather ^attenuated, and obtusely angulated above; dorsal edges 

 scarcely sloping and nearly straight, the front being very slightly 

 convex, the hinder somewhat refuse; ligament large and promi- 

 nent ; umbonal ridge and fold quite obsolete ; teeth distinct and 

 generally tinged with rose-colour, the lateral one approximate.

T. testa T. Timorensi simillima, sed abbreviate, et ovali-subtri-

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 Sinuata, but 

 the only specimen I have ever seen (purchased with this name 

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

 nounced distinct by every Conchologist who has inspected it.

 sinuated posteriorly, and somewhat swollen in the middle ; ante-
