Thoiigli by many the Briiniiich's GuilU'iuot lias been regarclocl as merely a local 

 race of the common species, it has of late become generally regarded as having good 

 claims to be considered a distinct species. It appears to have to a large degree the 

 same distribution as has the troile, and so far as it has been observed, the same habits.
