former, and am inclined to think that all may exhibit more white on the head in winter than 
summer. Many additional specimens will, however, he 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 intolerable 
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 vertebrae; the stretched skin measures 19 inches; the tail vertebrae, 8; the entire tail, 10; the hind feet, 3g. 
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.
