 dentition heavy, as compared with Felix dpurhc. 



Compiiriaon <nul i-nt/iial tinii!<iirf>i/nif.'<. —VAWoi's account ot the cranial 

 characters of Fidi« tifr<( Fischer,- based on specimen No. 1226, British 

 Museum Collection (locality not given), contains, besides nonessentials, 

 the foUowiuii': "nasals are broad, and on a line with the processes of the 

 maxillas at their articulation with the frontal bone. * * * Au<litory 

 bulhe prominent, oblong: mastoid foramen of a triangular shape. Zy- 

 goma well arched. Canines moderate." No cranial measurements are 

 given. The skull of the type and only specimen of Felix f(isx(( fa differs 

 from the above in having the nasals bones narrow, audital bulhe pointed, 

 mastoid foramen oval, zygoma slightly arched, canines large. The 

 skull of 7^<'^/.v '/;>'/'7/f' is readily distinguished from that of F. foxxata by 

 the absence of a frontal fossa, the marked lateral constriction of the au- 

 dital bulla', the narrowness of the posterior narial fossa, and the small 

 size of the teeth. It is also noted that the infraorbital foramina are 

 double. The two species are of similar size. The following dimensions 

 of the type skull of Fdixfuxxatu are followed by those of the type of F.
