108 EARED GREBE. 



have given no description of the female of the Clangula vulgaris for 

 comparison, that of the female of the C. Barromi agrees in all respects 

 with the female of the former. 



Finally, finding in my specimen of " Clangula Barromi,"" that the 

 feathers of the neck, and of the white patch before the eye, are ob- 

 viously much worn, as are the tips of the smaller white wing-coverts, 

 and the white parts of the tips of the scapulars, beyond which the black 

 margins extend unaltered, I think it is thus, in the first place, easy to 

 account for the appearance of the black band on the wing ; and, second- 

 ly, cannot but infer that the alleged Rocky Mountain Garrot is simply 

 the Golden Eye in its summer plumage. 



It may be remarked that Beisson's description and figure of the 

 " Garrot," represent it in that state in which Mr Swainson has con- 

 sidered it as constituting a distinct species. 



This species is abundant on the Columbia River, where it was pro- 

 cured by Dr Townsend, who has sent me a fine specimen of the male, 

 having a narrow bill, an elliptical, but not crescentic, white spot, the 

 head green, purplish above, and no black band on the wing, but the 

 posterior lateral feathers margined and tipped with black. This spe- 

 cimen therefore presents a combination of the characters of both al- 

 leged species.

The specimens from which my figures of this species of Grebe 

 have been taken, were lent me by my noble and kind friend the Right 

 Honourable the Earl of Derby, who received them from North Ame- 

 rica, where, as I am assured, it is not uncommon, although it has not 

 been my good fortune to meet with it.
