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 shghtly the shorter, rounded at the extremity ; posterior side 

 rather attenuated, and obtusely angulated above; dor.-^al edges 

 scarcely sloping and nearly straight, the front being very slightly 

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

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

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

 much more sloping, and the front one not retuse. 



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

 the oidy specimen I have ever seen (purchased with tliis name 

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

 nounced distinct by every Conchologist taIio has inspected it.
