NEW YORK ZOOLOGICAL SOCIETY: 
consists of many yellow-tipped white hairs slightly mixed with brown. 
The lower surface of the neck is colored like the back and sides, but 
is darker where it joins the body. This color is continued over the 
breast to a point about six inches back of the forelegs, where it is sharply 
divided by the apex of a broad triangular rear area of white. This 
white tract covers the abdomen up to the flanks, the space between the 
thighs, and extends on upward until it terminates high up on the hind- 
quarters in a rump patch similar to that of Ovis montana. In this. 
light-colored rump patch the tail appears as a diamond-shaped patch 
of blackish-brown hair. The darkest portions of this animal are be- 
hind the forelegs, on the outside of the forearm, and on the outside of 
the thigh from the hock joint upward. The front edges of the legs 
are dark colored, while the rear edges are light, and a light-colored 
band extends centrally up the inside of the thigh. 
Pelage-—On summer specimens the pelage is short and compact, and the 
animal has a very trim and neat appearance. Of the specimens that 
have been collected up to this date, sixteen have been examined by 
the writer, and upon all the pelage is stiff and coarse. The long, fine, 
and abundant hair of the neck and abdomen of Ovis fannini is con- 
spicuously absent, a fact which is only partly accounted for by the 
season in which the specimens were collected. 
Horns.—The wide-spreading, deeply grooved horns of Ovis stonei are one 
of the most prominent characters of this species. The horns are light 
in color, slender, and deeply annulated near the head. Their most 
prominent mark is a deep groove under the superior edge, a quarter 
of an inch deep for the first seven inches out from the base, but usually 
disappearing entirely about eleven inches out. The back of the horn, 
at the middle, is almost flat. 
Measurements.—Of actual measurements of Ovis stonei in the flesh, none 
are available for adult males, those taken by Mr. Stone having, un- 
fortunately, been mislaid beyond recovery. Regarding the size of this 
animal, however, Mr. Stone has furnished me with the following state- 
ment: ‘‘ The sizes of Ovis stonei and O. dalli are identical; there is 
no perceptible variation between the sizes of the two species. I know 
this from actual measurements.’ Regarding specimens of other ages, 
Mr. Stone has kindly supplied the following records of measurements 
made by him:
