 The specimen was procured by Mr. Townsend on the Colum-

I am obliged to confess that I should not have ventured to pub- 

 lish this species as distinct from G. borealis, on my own respon- 

 sibility. The discriminating eye of Dr. Richardson, however, 

 who has studied this genus more carefully than I have had an 

 opportunity of doing, may have detected marks of difference 

 which I have not been able to discover. — Bach.
