Genus CHEN, Boie. 



Chen, Roie, Isis, 1822 (type, Aiiser hy2)erhoreus, Pallas). 



Exanthemops, Elliot, Pr. Pliilad. Acad. 1868, (type, Anser Rossii, Baird). 



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

 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, G. Rossi, while agreeing strictly with A. hxjperhoreus in 

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

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



1 Clienalopex, Stephens, Shaw's Gen. Zool. XII. ii. 1824, 41 (type, Anser juhatus, Spix. — Scl. & 

 Salv. 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 require another generic name.]
