Hab. America. 



Skull, adult : length .ot}, width S\ inches. 



The skulls of these three species are very similar, only differing 

 a little in size ; perhaps they are only local varieties of the same 

 species. 



4. Felis picta. 



Leopardus pictus. Gray, Ann. & Mag. N. H. x. p. 260, 1842. 



Hab. Central America. 



Skull : length 5|, width 3| inches. 



The skull of F. pardalis and the typical specimens of F. grisea 

 and F. melanura are very similar in shape, size, and structure. 

 The nasal bones vary in shape ; in some skulls they are short, broad, 

 and gradually attenuated ; in others the nasal bones are longer, 

 very broad in front, and then suddenly narrowed at about half their 

 length ; but the diff'erent skulls vary in this respect, and the two 

 forms gradually pass into each other. 



The skull of an adult F. pardalis is 5 inches long and 3^ inches 

 wide, of the typical F. grisea h\ inches long and 3^ inches wide ; 

 the nose rather concave on the sides behind. In the typical F. me- 

 lanura the length of the adult skull is u\ inches, width 3 inches 

 7 lines ; intermaxillce elongated ; orbits moderate, incomplete be- 

 hind ; face broad, rather produced.
