                             LITTLE NIMBLE WEASEL.
                              [Long-tailed Weasel]

                  PLATE CXL.--MALE and FEMALE.  WINTER PELAGE.

     P. Magnitudine intermedius P. pusillum inter et P. fuscum; cauda longa,
auriculis prominulis, aestate supra dilute fuscus, subtus albus, hyeme corpore
toto caudaque niveis, cauda apice nigro.


     Intermediate in size between P. pusillus and P. fuscus; tail, long; ears,
prominent.  Colour, in summer, light brown above, white beneath; in winter, body
and tail, pure white, except the tip of the latter, which is broadly tipped with


     This hitherto undescribed species is light, slender, and graceful, with
well proportioned limbs, giving evidence of activity and sprightliness; it may
be termed a miniature of the ermine; it stands proportionately higher on its
legs, and although the smaller animal of the two, has the most prominent ears;
the hair is softer and shorter, both in summer and winter, than in either the
ermine or Brown Weasel (P. fuscus); whiskers, numerous but rather short.  Head,
moderate; skull, broad; nose, short and rather pointed; feet, small; nails,
partially concealed by the hair on the feet; tail, long, covered with fur to
within one and three quarters of an inch of the end, where it terminates in long
straight smooth hairs.


     In summer:  Head, ears, neck, outer surface of thighs, all the upper
portions of the back, and the tail on both surfaces to near the tip, light
brown, which is the colour of the hair from the roots to the tips; end of the
tail, black; chin, throat, chest, belly, and inner side of thighs, white; the
brown colour extends far down on the sides and flanks, leaving a rather narrow
stripe of white beneath, which is broadest on the neck; the line of demarcation
between the upper and under colours on the sides is distinctly but somewhat
irregularly drawn.  All the feet are brown; whiskers and nails, dark brown;
teeth, white.
     In winter:  Pure white on the whole body, and for about three inches on the
tail; tip of the tail, black for an inch and three quarters; tip of nose, flesh
colour; whiskers, mostly white, a few black.

     We preserved a specimen of this little animal during several months in the
winter, forty years ago, in the northern part of New York; it had been captured
in a box trap, which was set near its hole in a pine forest, whither we had
tracked it on the snow, believing from its small foot-prints that it was some
unknown species of Rodentia.  What was our surprise when on the following
morning we discovered the eyes of this little marauder prying through the
crevices of the trap.  Supposing it to be a young ermine we preserved it through
the winter, under the impression that it would become tame, and increasing in
size, attain its full growth by the following spring; we were, however,
disappointed in our expectations; it continued wild and cross, always printing
on our gloves the form of the cutting edges of its teeth whenever we placed our
hand within the box.  It concealed itself in its nest, in a dark corner of the
cage, during the whole day, and at night was constantly rattling and gnawing at
the wires in the endeavour to effect its escape.  We fed it on small birds,
which it carried to its dark retreat and devoured greedily.
     Having placed a common Weasel, twice the size of our animal, in the cage
with it, the ermine immediately attacked our little fellow, which ensconced
itself in a corner at the back of the cage, where with open mouth and angry
eyes, uttering a hissing spitting or sputtering noise, he drew back his lips and
showed his sharp teeth in defiance of his opponent.
     To relieve him from a troublesome companion we removed the ermine.  Towards
spring we placed a Norway rat in his cage in order to test his courage.  The rat
and the Weasel retreated to opposite corners and eyed each other during the
whole day;  on the following morning we found the rat had been killed; but the
Weasel was so much wounded that he died before evening.
     We have no other information in regard to the habits of this Weasel.  Its
burrow, the entrance to which was very small, and without any hillock of earth
at its borders, was situated in a high ridge of pine land.
     We have no doubt that, like the ermine, in prowling about it finds its way
into the retreats of the meadow-mouse, the little chipping squirrel, and other
small animals, for although the rat above mentioned was too formidable an
opponent, we are confident it could easily have mastered the little Tamias

                           GEOGRAPHICAL DISTRIBUTION.

     We have only observed this Weasel in the northern part of the State of New
York, but the specimens from which we drew our figures were procured by Mr. J.
G. BELL in Rockland county in that State.
