PhaeVum cethereus, Bi.oxn. Voy. Blonde, 1826, 251 (not of Linn., 1766). 

 - Audubon describes the bill of the male as " orange-red," and that of the female as yellow ; but he 

 seems to have had P. cethereus in mind in the former case, though his description otherwise applies exclu- 

 sively to P. flavirostris. He says that both sexes have the "iris brown; tarsi and base of toes yellow, 

 the rest and the webs black, as are the claws" (" Birds of America," Vol. 7, p. 65).
