Numerous divisions have been 

 proposed in • the first three 

 species as established by Lin- 

 naeus, but none have received 

 general recognition. Blyth has 

 established the name isahellina 

 for the Indian form of the Lynx, 

 and de Winton, who studied the 

 group, has accepted Gray's name 

 of afjinis for the Indian repre- 

 sentative of choAis, on the ground 

 of " its longer tail, bright fox- 

 red ears, and lighter build", its 

 narrower skull and slighter 

 teeth, (A. M. N. H. (7). ii. 

 p. 292, 1898). Blanford's key, 

 modified to this extent, is as 

 follows : — 



Key to the species of Felis. 



A. — Ears of moderate length, not tufted. 

 a. Very large, total length over eight feet.
