TEREBRATULA resupinata. 
TAB. CL.---Fig. 3 and 4. 
Spec. Cuar. Oblong ovate, front depressed by 4 
large rounded plait, sides elevated, rounded : 
lower valve obtusely carinated, with a sharp 
beak and a longitudinal ridge along each side. 
Seuninimmesies cca 
Lexern about one-fourth greater than the width: the 
sinus on the front is rounding in the middle with 
straightish sides; the lower sides of the shell are 
rounded and entire ; the carina of the lower valve is very 
broad and rounded.

in comparison with it; on which account, although a 
plainer shell without plaits on the edges, it has so general 
a resemblance at first sight, that the two have been laid 
together as the same species. I believe neither are yet 
commonly known; all that I have yet seen have ay 
ochraceous tint,
