27822. Portion of the cranium, in a much-crushed condition, but 
exhibiting the palate and cheek-teeth; from the Lower 
Miocene of Cournon (Puy-de-Déme), France. This spe- 
cimen, together with the next, is the type of the species. 
It is described by P. Gervais in the passage cited, and 
also on page 250 of the 2nd edition of the same work. 
“ The carnassial has a length of 0,068, and the tuber- 
cular molar is larger externally than internally, forming 
a triangle of which the external border of the crown is 
the base. This tooth is also remarkable by the presence 
on the anterior border of a transverse subtrenchant 
crest.” The first premolar is very minute.
