GOLDEN-EYE DUCK. 



FULIGULA CLANGULA, BoNAP. 

 PLATE CCCCIII. Male in Summer. 



I HAVE been induced to give a figure of the Golden-eye in what I 

 consider its summer plumage, because I find it figured and described 

 by Dr Richardson and Mr Swainson in the Fauna Boreali- Ameri- 

 cana, under the name of " Rocky Mountain Garrot, Clangula Barrovii.''' 

 Before offering any remarks on this alleged new species, it may be ex- 

 pedient to give a description from the specimen represented in the 

 plate, which was presented to me by the Earl of Derby, to whom it 

 was given by a member of one of the late Arctic Expeditions. Let 

 the reader turn to the description of the Golden-eye, at p. 322 of vol. 

 iv. ; and compare with it the following : 



With regard to the form and proportions of the parts, and the 

 structure and arrangement of the plumage, there is no difference what- 

 ever. All that is requisite to be remarked on the latter subject is, 

 that the second primary is longest, as is the case in several specimens 

 of that commonly called the Golden-eye. The colours are also simi- 

 lar, with very slight differences. 



Bill black. Feet orange-yellow, webs dusky, claws black. Head 

 and upper part of neck deep greenish-blue, changing to deep dusky 

 purple in certain lights. Back, posterior scapiUars, inner secondaries, 

 edge of wing, alula, primary coverts, primary quills, and four outer se- 

 condaries, black, the back being darker and glossy, the wing-feathers
