Genus CHEN, Boie.

Exant)iei)iops, Elliot, Pr. Pliilad. Acad. 1868, (tyjie, Anscr Eossii, Baiud). 



Of the three North American species of this genus, two, C. lnjperboreus, the type, and C. cmru- 

 lescens, are precisely alike in the details of form, the only difference being the coloration, which is 



C. hyperhoreus. 



very distinct in the two ; the third species, C. Rossi, while agreeing strictly with A. hyperboreus in 

 plumage, both in the adult and young stages, differs decidedly in the form of the bill, which is (pile 

 peculiar. It seems unnecessary, however, to adopt the generic term Emnthcmops, proposed for 



1 aienalopcx, Stephens, Shaw's Gen. Zool. XII. ii. 1824, 41 (type, Anscr jubatiis, Spix. — ScL. & 

 Salt. P. Z. S. 1876, 360). [The Egyptian Goose seems hardly strictly congeneric with the South Ameri- 

 can species upon which this genus was based, and may reipiire another generic name.]
