Native. UUginal. Perhaps one or two others might have 

 been added to the estimate of six counties, the number in 

 which this species has been already ascertained. Those of 

 Argyle, Banff, Ross or Sutherland, would seem not un- 

 likely. With the progress made in re-converting the sheep- 

 walks into deer-forests, in the Highland counties, this 

 species may become more frequent ; for it does not seem 

 to be natm-ally restricted to rocky places and precipices, 

 but rather to be adapted to the stream-sides and swampy 

 spots on the declivities of the mountains, where, at present, 

 it is destroyed by sheep.
