 tail (about 9 inches long) is usually half as long as the head 

 and body (about 18 inches).

 (about 3 inches) in the female. Dental formula: I 3/3, C 1/1,

Distribution. — The marten was recorded from Cook County 

 by Robert Kennicott (1855:578), and a marten skeleton taken 

 "in northern Illinois" is preserved in the Museum of the Chi- 

 cago Academy of Sciences. Probably the marten once occurred 

 in several of the northern counties of our state where there 

 were stands of white pine. There are no records of its present- 

 day occurrence in Illinois, but there are several for Wisconsin. 

 The marten is an arboreal animal, principally of the conifer- 

 ous forests. The subspecies in Illinois was Martes americana 

 americana (Turton). The species is found from Labrador, 

 Newfoundland, Nova Scotia, northern New York to Alaska, 

 and southward in western Canada to the northwestern United 

 States, with extensions in the Sierra Nevada to south-central 

 California and in the Rocky Mountains to the northern part of 

 New Mexico.
