 as follows : — '•' Transversely oblong ; valves deep, carinated ; the 

 keel acute, extending from the beak to the angular extremity of the 

 narrow, oblique, produced posterior side; beaks short, incurved, 

 close to tbe small heart-shaped anterior side."

Nice. — Among the mammalian remains enumerated by Risso from 

 the bone breccia of the Castle Catinat at Nice, are bones and teeth of 

 ' Lagomys.' • Remains of the same genus have been more recently 

 mentioned by Riviere, from a paleeolithic deposit discovered by him 

 in a small cave, Lympia, inside the town of Nice.^
