former, and am inclined to think that all may exhibit more white on the head in winter than 

 summer. Many additional specimens will, however, be required to settle the question definitely. 



NOTE. A marten from Cape Flattery, received from Dr. Suckley while these sheets are passing through the press, is in tolerable 

 winter fur, with the soles well covered with hair, except on the tubercles, which are visible. It is entirely of the pine marten 

 pattern of coloration, not like the sable ; the upper part of the head is not lighter than the back, and the reddish yellow patch 

 on the throat is very distinct and well defined. In all points it agrees with the summer specimens from the west above referred 

 to; a remarkable uniformity of coloring pervading all of them. Its outstretched hind feet reach within an inch of the end of the 

 tail vertebra; the stretched skin measures 19 inches; ths tail vertebre, 8; the entire tail, 10; the hind feet, 3|. 



1 have not now the means of knowing within what limits the white headed or sable-like martens, such as I describe from 

 Essex county, New York, are found. I am, however, still more than before, inclined to the belief that we have two species, 

 one representing the pine marten, with dark head; the other similar to the sable, with whitish head; both, probably, distinct 

 from the corresponding Old World species, the martens at least.
