The strongly marked species of Mountain Sheep which now 
bears the name of Ovis stonei was discovered in the Cheonnee 
Mountains of northern British Columbia, at the head-waters of 
the Stickine and Nass rivers, in the summer of 1896, by Mr. An- 
drew J. Stone, in whose honor the species was named. It in- 
habited an elevation of 6,500 feet, which is about 4,000 feet above 
timber line. Three of the specimens collected were mounted in 
Missoula, Mont., and exhibited at the New York Sportsmen’s 
Show in the winter of 1897, where they were at once recognized 
as representing a species up to that time unknown. The speci- 
mens were purchased by the American Museum of Natural His- 
tory, and described by Dr. J. A. Allen in the Bulletin of that in- 
stitution, Vol. IX., pp. 111-114, pl. 2, on April 8, 1897. 
Thus far nothing positive is known of the geographic range 
of the Black Sheep save the facts that have been furnished by 
Mr. Stone himself. On this point he makes the following state- 
ment :* 
“The range of Ovis stonei extends throughout the Cassiar Mountains, 
and in the Rocky Mountains, east of the Cassiar, north to where Beaver 
River, a tributary of Liard River from the north and west, breaks through 
the Rockies near latitude 60°. I believe that the Rocky Mountain divide, 
between the head-waters of the Peace River and those of the Fraser River, 
forms the dividing line between its range and that of the southern Ovis 
cervina. Its western limit very nearly conforms to the Cassiar Mountains 
and their numerous spurs.” 
In 1896, Mr. Warburton Pike, while journeying down the 
Yukon River, saw at Hoole Cafion, on the Pelly River, near Pelly 
Mountains, two skins and heads of mountain sheep, which he 
has described as follows :+ 
“The horns were exactly like those of the Big Horn of more southern 
latitudes, and the skin gave no signs of the gradation of color known to 
exist between the true Ovis montana and the Ovis dalli of the northern 
mountains.”
