(3990) Atlapetes schistaceus (Boiss.). 



Tanagra schistaceus Boiss., Rev. Zool., 1840, p. 69 (Bogota). 



A common species in the Temperate Zone of all three ranges. 



I find no racial variation, but specimens from the Western and Central 

 Andes average slightly larger than those from the Eastern.

Met with only in the Temperate Zone of the Eastern Andes, at El Piiion 

 where it was common. In the Central Andes it is replaced by the nearly 

 allied A., p. papallactce Hellm.

Atlapetes pallidinuchus obscurior Chapm., BuU. A. M. N. H., XXXIII, 1914, 

 p. 186 (Santa Isabel, Cen. Andes). 



Inhabits the Temperate Zone of the Central Andes and southward into 

 Ecuador. I have seen no Ecuador specimens, but the form from Papallacta, 

 eastern Ecuador, recently separated by Hellmayr (whose descriptions did 

 not reach me until after my paper describing the bird as A. p. obscurior 

 was published) is doubtless the same as the Colombian bird.
