farther, to the Little Missouri River, in western North 

 Dakota. 



In going southward, the goat halted at the Teton 

 Mountains, Wyoming; but the mountain sheep has gone 

 on to the lakes of Santa Maria in Chihuahua, Mexico, 

 and southwestward to the lower end of the Lower Cali- 

 fornia Peninsula. 



As the Big-Horn goes northward, it is finally replaced 

 in northern British Columbia by the Black Sheep (Ovis 

 stonei), a species which as yet is but little known outside 

 the basin of the Stickine River, and the mountains which 

 surround it. It is now certain, however, thanks to the 

 explorations of Mr. Charles Sheldon, that the range of 

 the latter species extends northward from the Stickine 

 River to the Macmillan River, in latitude 63. Just 

 where the Black Sheep and Big-Horn come together, no 

 one is as yet able to say; but it is very probable that the 

 extreme northern and western boundaries of the latter 

 species will shortly be determined. 



The White Sheep (Ovis dalli), has been observed as 

 far south as the Schesley Mountains, the first range north 

 of the Stickine River. This means that in the south- 

 eastern portion of its range, the White Sheep is found in 

 the territory of the Black Sheep. It is impossible to pur- 

 sue this point any farther without forestalling the publi- 

 cation of the results of Mr. Charles Sheldon's very valu- 

 able scientific explorations, and studies of mountain sheep 

 in some hitherto unknown portions of the great Yukon 

 Territory. If Ovis fannini is eventually abandoned, as a 

 distinct form, the author will be consoled by the knowl-
