Type locality — Eastern Canada. 



Distribution — Practically the whole of northern North America, from 

 the northern border of United States northward, farther south 

 in the Rocky Mountains, in New York and in the mountains in 

 Pennsylvania; formerly its range extended as far south as Illinois 

 and Indiana. Replaced in Alaska and New Foundland by allied 

 forms. 

 Description — General color light gray, more or less grizzled with 

 brown ; belly grayish white ; throat grayish white ; ear tufts brownish 

 black, usually more than 1.50 inches long; a ruff of long hairs on 

 sides of head, grayish white, the middle hairs with ends brownish 

 black and forming a black patch in middle of the ruff ; end of tail 

 wholly black; feet large. 

 Measurements — Total length, about 38 in. (965 mm.); tail vertebrae, 4 

 in. (102 mm.); hind foot, 9.75 in. (248 mm.). 



The Canada Lynx is now a comparatively rare animal within our 

 limits and the few that remain are confined to northern Wisconsin, 

 although in early days its range extended considerably further south. 

 There is always more or less likelihood of the untrained observer con- 

 founding the Wild Cat (L. rufus) with this animal, and many records 

 are untrustworthy for that reason ; but there are numerous well authen- 

 ticated instances of its occurrence in Indiana (see Hahn, /. c, p. 544); 

 and Kennicott includes it in his list of mammals of Cook Co., Illinois 

 (/. c, p. 579). I have seen specimens (skins or skulls) from Douglas
