ength of the hairs on the back is 2 to 2-1/2 inches. The iris is
brown. The horns are subtriangular, touching each other at the base,
curving gradually with a long sweep backwards and outwards; and,
after completing a full circle, the compressed points again curve
backwards and outwards; their surface is more or less closely
transversely ridged.

"The colour of full-grown females does not differ essentially from
that of the males, except that the former have much less white on
the middle of the upper neck. The snout is sometimes brown, sometimes
almost entirely white, the dark eye-pits becoming then particularly
conspicuous. The dark ridge along the tail is also scarcely traceable.
In size, both sexes of _Ovis Polii_ appear to be very nearly equal,
but the head of the female is less massive, and the horns, as in allied
species, are comparatively small: the length of horn of one of the
largest females obtained is 14 inches along the periphery, the
distance at the tips being 15 inches, and at the base a little more
than one inch. The horns themselves are much compressed; the upper
anterior ridge is wanting on them; they curve gradually backwards
and outwards towards the tip, though they do not nearly complete even
a semicircle. In young males, the horns at first resemble in
direction and slight curvature those of the female, but they are
always thicker at the base and distinctly triangular.

"The length of the biggest horn of male along the periphery of curve
was 56 inches, and the greatest circumference of a horn of a male
specimen at the base 18-1/2 inches.

"Mr. Blyth, the original describer of _Ovis Polii_, from its horns,
was justified in expecting, from their enormous size, a
correspondingly large-bodied animal; but in reality such does not
appear to exist. Although the distance between the tips of the horns
seems to be generally about equal to the length of the body, and
although the horns are very much larger, but not thicker or equally
massive, with those of the _Ovis Ammon_ of the Himalayas, the body
of the latter seems to be comparatively higher. Still it is possible
that the _Ovis Polii_ of the Pamir may stand higher than the specimens
described, which were obtained from the Tian Shan range.

"Large flocks of _Ovis Polii_ were observed on the undulating high
plateau to the south of the Chadow-Kul, where grass vegetation is
abundant. At the time the officers of the Mission visited this ground,
i.e. in the
