wliicli ai'(> iiinro ov less imperfect, l)ut after an examination of specimens of 

 L. suhasqnilateralis from Le Mans in the Museum of Palfeontology at Paris I am 

 inclined to refer them to that species. Tn the specimens from Le Mans the 

 number of rilxs is sometimes greater than is shown in D'Orbigny's figure, also the 

 ears may be less sharply separated from the valve, and in one case the hinge-line 

 was seen to be relatively longer. 



Types. — From the Cenomanian of Le Mans. The specimens here figured are 

 in the British Museum. 



Distnhution. — Upper Greensand (zone of Pecten asppr) of Warminster.
