"Iris dark brown, feet pink, bill bright orange-red." 

 Messrs. >Salvadori and Festa* have most correctly pointed out 

 the difl'erences between specimens from Western and Eastern 

 Ecuador. The large series in the Munich Museum, however, 

 proves that the birds from the Avestern slopes of the Andes are 

 clear l_y distinct from^. erythrorhynchus of Bogota, and constitute 

 a third, hitherto overlooked race. A. spectabilis, A. erythro- 

 rhynchus, and the new form are evidently the southern repre- 

 sentatives of the Central American A. aurantiirostris Lafr. t and 

 should, according to ray view, be ranked as subspecies of the 

 latter. The northern bird may, however, readily be distinguished 

 by its much larger, heavier bill, much broader, black jugular band, 

 and pure olive-green black. 



Characters, range and synonymy of the three races are as 

 follows : —
