while in / jaguaronadi 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 / jaguarondi, whereas in &. braccata 
they are of two contrasting colours, both different from that of 
the head. In /& 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 / 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 / dbraccata 
from /. jaguwarondt. ‘The only approach to any of the peculiar 
characters of / draccata in descriptions of / jaguarondt, 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.
