THE EYRA. 1 53 



while in F jaguarondi the border presents an acute angle for- 

 wards, as it follows the upper border of the nostrils above. 



As regards coloration, the hinder surfaces of the ears resem- 

 ble the top of the head in F. jaguarondi, whereas in F. braccata 

 they are of two contrasting colours, both different from that of 

 the head. In F jaguarondi the internal surfaces are like the 

 hinder ones ; whereas in the present species they are totally 

 different, resembling those of various spotted Cats. The legs 

 of F jaguarondi are coloured on their outer surfaces like the 

 back, and are black inferiorly ; whereas in the present form 

 they are marked by cross-bands superiorly, and on their lower 

 halves are totally black. 



After mentioning that the difference in the length of the 

 tail in the two forms may prove to be a character of small 

 importance, Professor Cope observes that " the aggregate of 

 characters indicates the specific distinctness of F braccata 

 from F jaguarondi. The only approach to any of the peculiar 

 characters of F braccata in descriptions of F jaguarondi, which 

 I can find, is in that by Mr. Alston in the * Fauna Centrali- 

 Americana,' who states that there are transverse bars on the 

 inside of the legs." 



Distribution. — South Brazil. The species was established on 

 the evidence of a single skin, obtained either from Rio Grande 

 do Sul or in Matto Grosso, the loss of the label having left 

 the precise locality a matter of uncertainty.
