This interesting observation is capable of but two interpreta- 
tions: (1) the specimens seen were Ovis montana, which there- 
by makes a long leap northward, from Lat. 55° to 61° 45’, about 
650 miles; or, (2) they were Ovis stonet, either weathered or 
slightly immature specimens, which in either case would very 
closely resemble the dark British Columbia phase of Ovis mon- 
tana. Mr. Stone himself is authority for the range of his Black 
Sheep up to Lat. 60°, within ninety miles of Hoole Cafion. It 
is my belief that the specimens seen by Mr. Pike were really im- 
mature Ovis stonet, and mark the most northerly limit yet re- 
corded for that species. 
In this connection it is worth while to note that, up to this date, 
there has been no record of the presence of both the Black Sheep 
and White Sheep in the same locality, nor of any mixing of either 
of these with the Big Horn.
