1. c). The belly is again lighter, almost whitish with a tinge 

 of rust red colour. The region below anus is buffish. The tail 

 has above the colour of the back, but the end is entirely black 

 for 12 — 13 cm above and below. Otherwise the lower side of 

 the tail is dull buff. 



A young specimen of the same Puma measuring: head and 

 body about 68 cm, and tail about 38 cm, is similar, although 

 a little more reddish in its general colour. The black is more 

 confined to the clorsal area than in the old male. The lower 

 side has about the same distribution of colours as in the adult, 

 but the white areas are comparatively larger and the »red» 

 falls between buff (309.1) and dead leaf (321, 1). There are 

 four dusky cross-bars on the inner side of the före leg, the up- 

 permost at the elbow. The hair round the pads of the soles is 

 dark brown. The upper side of the tail is brown and its tip 

 blackish brown.
