320 FAUNA ANTIQUA SIVALENSIS. 



The orbit is smaller tlian in the Tiger ; the post-orbital 

 processes of the malars and frontal are more apart, and the 

 osseous ring consequently less complete. 



Regarding the relations of the fossil with respect to other 

 species — 



The fossil Lion of Gaylenreath, F. spelcea, differs from it 

 in the great size, equalling that of the Lion in the outline of 

 the head, breadth of forehead, depth of zygomatic arches, 

 position of the infra-orbital foramina, and inconsiderable 

 sagittal crest. 



The fossil F. antiqua differs in being greatly smaller. 

 The existing Lion is much larger, differing also m its recti- 

 linear profile, shortness of head, and want of prominence in 

 the sagittal crest and occipital. 



The points of distinction and resemblance with the Tiger 

 have been noticed in detail. 



The Panther somewhat resembles the fossil in the moderate 

 convexity of the head, but differs in size and in the little 

 prominence of the sagittal crest. The Jaguar has the same 

 elevated direction of the zygomatic arch as the fossU, but 

 differs greatly in the outline and form of the head. 



The Cougouar has one character peculiar to it and the fossil 

 in the genus, in the face being shorter than the cranium ; 

 but it differs in size and form. 



The other species of the genus differ at once in size. 



We have named the fossil the Felis eristata, from its most 

 prominent character, the elevation of the sagittal crest. 



The position in the genus will probably be after the Tiger. 

 Its size is intermediate between that species and the Jaguar. 



We are indebted to Walter Ewer, Esq., of the Civil Service, 

 for an examination of the fossil, which was found by collec- 

 tors employed by that gentleman, under the direction of 

 Captain Cautley.
