especially) by darker coloring. A spot behind the ear and a smaller one above and behind 
the eye are similarly colored. The color of the head differs from that of the trunk only in the 
greater or less amount of sprinkling of white. The upper margin of the ear is rounded, with- 
out a projecting blunt point. The appressed whiskers reach behind farther than the ear, The 
blotch on the lower part of the neck ends anteriorly under the throat in five to six small points 
(three, more rarely four, median, and two lateral); posteriorly, it terminates always in one 
simple point, continued but ending between the fore legs; this spot is usually light yellow, or 
varying to light brownish orange yellow, not rarely interrupted by single brown spots. The 
under fur in the gular blotch is whitish, or yellowish orange, or almost white. The paws and 
inside of the feet are distinguished from the outer side of the lower thigh (which is colored 
more or less like the trunk) by a blackish brown darker color. All the stiff straight contour 
hairs of the tail (with the yellowish gray under fur) in winter are much lengthened, and form. 
a bushy brush from the base; the tail is grayish brown nearly to the middle, then blackish 
brown, with single whitish contour hairs. The entire trunk, including the lower thigh, is 
covered with moderately stiff light grayish brown softer hairs, a little darkest on the lower 
thigh. The under fur of the trunk, with the exception of the throat, in winter is light ash 
gray at the base and in the middle; at the end light brownish gray. The moderately stiff 
bristly hairs of the toes do not conceal the claws, being constantly shorter than they are. The 
pads of the toes, even in winter killed specimens, with hairs only on the sides, and enclosed by 
them, as also the pads of the soles.

Mustela foina, Beech marten.—As there is no American species with which the Mustela foina 
needs to be compared, it is here only necessary to say that it differs from the JZ. martes, or pine 
marten, in the pure white color of its gular blotch, which is forked behind, and extends on either 
side, in one of its branches, to the upper part of the fore feet. The body is of a more reddish 
yellow brown color; the chin and snout are lighter, and not different in color from the upper 
part of the head ; the tail is brownish black, or black, from the base, with somewhat crisped 
hairs, and differs from the lower part of the back in color. The downy fur of all parts of the 
body is of a lighter whitish color. The tail is generally longer, with more vertebrz. 
I am, myself, however, far from admitting the identity of the American marten with the 
Russian sable, although it occupies a position intermediate between the latter and the WM. martes 
in size, length of tail, and coloration, as well as intrinsic value of the fur. The white headed 
varieties of New York are most like the sable; the darker headed ones of the western country 
like the pine marten. I have never seen winter specimens of the latter, nor summer of the
