Ocadia(?) nicoleti (Pictet & Humbert 1 ). 

 Syn. Emys nicoleti, Pictet & Humbert 2 . 



Known only by fragments of the carapace and plastron, the 

 former being the type. In the plastron the humero-pectoral sulcus 

 cuts the entoplastral at a high level, and the antero-posterior dia- 

 meter of that bone considerably exceeds the transverse. Of small 

 size. 



In the absence of any knowledge of the contour of the neural 

 bones of the carapace, the generic position of this species must be 

 regarded as provisional. The entoplastral presents, however, all the 

 characters of Ocadia. 



Hob. Europe (Switzerland). 



The originals of the following specimens are the types, and were 

 obtained from the Middle Miocene of Chaux-de-Ponds, Switzerland.
