MAMMALIA. 
19 
Compared with the skull of Felis chaus, that of F. shawiana is comparatively longer, 
it has the nasal portion more elongate, the face less convex, the breadth behind the postorbi¬ 
tal, processes less, whilst the processes themselves are longer and project further. The true 
lynxes have an even shorter and more convex skull, and so have the smaller typical cats. 
The skull of Chaus caudatus approximates to that of the true cats, being rounder and 
shorter than that of F. cliaus. The only skull I can find which approaches in form to that 
of Felis shawiana belongs to F. viverrina, the type of Gray’s genus Viverriceps , a cat with 
a peculiarly long head. 
Felis shawiana is distinguished externally from F. ( Chaus ) caudata by its much shorter 
tail, from F. chaus by being spotted throughout, and from F. torquata (F. ornata. Gray) 
by its shorter tail, more rufous colouration, and distinct black spots on the abdomen. It 
is very different from F. euptilura, 1 which has red spots on the sides and rufous bars across 
the breast. 
This cat appears to be common in the plains of Eastern Turkestan, around Kashgliar and 
Yarkand. Dr. Stoliczka has noted on the label of the original skin that the animal is found 
abundantly, and I have received the same account from Captain Biddulph, Dr. Scully and 
Mr. Shaw. 
In the figure on plate lb, the black spots on the belly have been omitted. Three views 
of the skull are given on plate lc.

1, Adult skin (probably purchased) sent from Leh ; 2, Skin of young animal without label; 3, skull of young- 
animal purchased at Kashgliar, and said to have been brought from Sarikol (the two last very possibly 
belonged to the same individual). 
The occurrence of the ounce, or snow leopard, as it is called by sportsmen, on the Pamir, 
might have been anticipated. It is found in parts of Southern Siberia, 2 throughout Tibet, 
on the Altyn-tagh, south of Lob-nor, and in Western Turkestan. To the east it extends to the 
Amur, where Schrenk found it abundantly, and it occurs to the westward on the mountains 
of Persia, Armenia and Asia Minor, being found in the latter country near Smyrna. 3

b 2, Skins (without skulls or feet) purchased at Kashgliar. 
Two fine skins, removed, without cutting open the belly, by an incision from the inse r- 
tion of the tail to between the thighs, are marked as purchased for Government by Captain 
Chapman in Kashghar ; one is said to have been brought by an Aksu merchant. Both 
belong to the European form of lynx, and not to the much paler F. isabellma 4 of Tibet.
