Descrqifiov. — Shell oval, moderately inequilateral ; length rather more than 

 1^ times thf height; left valve less convex than the right. Anterior part of 

 valve.s rounded. Posterior margin convex, subtruncate, more or less ob]i(|ue, 

 forming a blunt angle with the ventral margin. A slight carina extends from the 

 umbo to the postero-ventral angle and cuts off a flattened postero-dorsal area. 

 Umbones moderately prominent. I'allial sinus large, rounded. Postero-dorsal 

 area ornamented with small radial ribs; the remainder of the shell smooth 

 except for growth-lines. 



(1—6) BlaekdoAvii. 



Aj]iiiiti<'H. — T. slriijata Goldfuss,^ from the Aachen Greensand, is simihir in 

 form to T. iiueijunlix, but possesses fine radial ornamentation over the entire surface 

 of the shell. T. liui/imti, d'Orbigny,- is also similar in form, but appears to be more 

 nearly ecpiilateral and without radial ribs. 



A species of TcUimt found in the ]\leule de Hracquegnies was referred to 

 T. iiueqiniJis by Briart and Cornet, but it appears to differ in some respects fi'om 

 the latter. The specimens which I have seen from Bracquegnies are not 

 sufficiently well preserved to enable me to express a defiuito opinion as to their 

 relationship to T. insequalis.
