1033 NEW. YORK ZOOLOGICAL SOCIETY: 
western Canada was described by E. W. Nelson, and christened 
vis dalli, in honor of Professor William H. Dall, of Washing- 
ton, D. C. Next in order of discovery came Nelson’s Mountain 
Sheep (Ovis nelsoni), of southern California, described by Dr. C. 
Hart Merriam in 1897. In 1896, while on an exploring expedi- 
tion in the Cassiar Mountains, of northern British Columbia, Mr. 
A. J. Stone discovered the very interesting dark-colored species 
of Mountain Sheep described by Dr. J. A. Allen in 1897, and 
christened Ovis stonei, in honor of its discoverer. 
The discovery of gold on the Klondike River, Northwest Ter- 
ritory, has led to the discovery of still another species of Mountain 
Sheep, which may justly be regarded as the handsomest and the 
most striking in color markings of all known species of the Genus 
Ovis. | 
While in Victoria, British Columbia, last November, the at- 
tention of the writer was called by Mr. John Fannin to the skin 
and skull of a Mountain Sheep which had been sent down from 
Dawson City by Mr. Henry W. Brown, as a specimen of Ovis 
stonet, and presented by him to the Provincial Museum. An ex- 
amination of the skin, which is not only from an adult male ani- 
mal, but is also in perfect pelage and preservation, revealed the 
startling fact that it represents a species absolutely new to science, 
and so strikingly differentiated as to render its title to inde- 
pendent specific rank beyond question. It is hereby described 
and named in honor of Mr. John Fannin, Curator of the Provincial 
Museum of British Columbia, in recognition of his work as a 
naturalist specially interested in the animal life of the Northwest.

Colors.—Entire head and neck, breast, abdomen, inside of forelegs, and 
rump patch for four inches above insertion of tail, snow white. Entire 
body, except as above, brownish gray, giving the appearance of a 
white animal covered by a gray blanket. This color is produced by 
a nearly even mixture of pure white and blackish-brown hairs. The 
gray color covers the shoulders from the insertion of the neck down- 
ward to the knee, where it fades out. On the outside of the thigh, 
the gray color grows paler as it descends, until at the hock joint it
