black-brown ; the rubiginous cat, flecked with rust 

 red on a yellowish ground ; the F. etiptilura, brown- 

 yellow-grey with large reddish spots ; the F. skawiana, 

 greyish fulvous sprinkled with black like a serval 

 cat, constitute with some others an entirely separate 

 group. In this connection it is interesting to 

 remember that Geofl^roy's cat of South America 

 occurs in tivo phases, one having largish blotches 

 with pale centres, the other being punctated all over 

 with small solid spots; two distinct types of coloration 

 thus occur in the same species.
