surface, and towards the tip these become mixed with black 

 which finally dominates. 



The type specimen is a male with an approximate length 

 of head and body amounting to about 51 cm, and of tail about 

 27 cm. The fur is soft, but not silky, or fluffy. It is compa- 

 ratively short measuring about 2 cm on the upper neck, 3 cm 

 on the flanks and anterior back, but above the hind quarters 

 it is longer amounting to 4 cm or even more.

As these measurements indicate the prseorbital region of 

 the skull is very short. The brain-case is not very broad. The 

 sagittal and occipital crests are well developed, although the 

 former is short. The nasal region is pinched in as proved by 

 the great difference in breadth of the nasals in front and at the 

 end of the nasomaxillary suture. p 2 is entirely absent, and 

 m 1 is minute, situated on the inside of p 4 . 



This cat is related to Felis pajeros qarleppi Matschib 

 from Cuzco. When passing through Berlin recently I was 

 kindly permitted to examine the type of this latter race. I 

 f ound then that it had the blackish spöts of the lower side less 

 conspicuous, the reddish spöts of the sides smaller and more 

 continuous, the dark cross-bands of the hind legs less sharply 

 developed, but the cross-bands of the fore-legs complete and not
