cosmopolitan distribution. The Cats of the New World are, 
however, as a rule, markedly distinct from those of the Old, 
although the Lynxes form a marked exception to this rule. 
Exclusive of the Old World Caracal, these animals are, how- 
ever, essentially a northern group; and it is therefore not 
surprising to find the common Lynx of Europe and Asia so 
closely allied to the Canadian Lynx as, in the opinion of many 
competent zoologists, to be no more than a local race. As a 
whole, the New World is not so rich in Cats as the Old; but it 
is noteworthy that in both hemispheres spotted, striped, and 
uniformly-coloured species occur. It is only, however, in the 
former that we meet with a species (the Jaguar) in which the 
dark rosettes have a central black spot ; while the great tawny 
American Cat (the Puma) differs from its Old World analogue, 
the Lion, in having been derived from a spotted instead of a 
striped ancestor. Moreover, the only striped American species 
is the Pampas Cat, in which the stripes are but poorly de- 
veloped ; and accordingly, if Dr. Eimer’s theory of coloration 
be the true one, it would seem that in this respect the New 
World Fedde are less specialised than their Old World cousins. 
Europe at the present day is remarkably poor in species of 
the Family, having only the Wild Cat, the common Lynx, and 
the Spanish Lynx. The warmer parts of Asia and Africa, on 
the other hand, may be regarded as the headquarters of the 
Family ; and it is here only that we meet with the Hunting- 
Leopard, which is not the sole representative of its genus, but 
is likewise common to the two continents. The only other 
species found both in Asia and Africa are the Lion, the 
Leopard, the Jungle Cat, and the Caracal, although a few 
essentially African species range into Syria. As regards the 
smaller Cats, several African species appear to be peculiar to 
the forest districts on the western side of that continent. 
As regards their geological distribution, it is not a little
