the forest regions of Central Europe ; though not an inhabitant of 
Britain during the historic period, its remains have been found in 
cave-deposits of Pleistocene age; F. cervaria, Siberia; PF. pardina, 
Turkey, Greece, Sicily, Sardinia, and Spain; and F”. isabellina, Tibet. 
The American varieties are F. canadensis, the most northern species, 
and F. rufa, the American Wild Cat or Bay Lynx, extensively dis- 
tributed from the Atlantic to the Pacific throughout nearly the 
whole latitude of the United States, but replaced in Texas and

Washington territory by I. fasciata. 
In both cases, as might be supposed, specimens obtained from 
the more southern climates are shorter in their fur, more brightly 
coloured, and more distinctly spotted than those from colder regions. 
When only a few individuals of each most markedly different form 
are examined the distinctions are sufficiently evident. The occur- 
rence, however, of transitional or intermediate forms makes it 
extremely difficult to draw the line between the different varieties 
or species, or to assign definite characters by which they can be 
separated. Wherefore it is best at present to accept the so-called 
species as only provisional, and wait until more abundant materials, 
with fuller knowledge of the localities from which they are derived,
