Specimens from the Temperate Zone at the north end of the Western 

 Andes have the characters of this race well developed but farther south in 

 this range true palpebrosa occurs. A single specimen from the Rio Toche 

 agrees with these West Andean specimens rather than with our series from 

 Laguneta, indicating that the faunal affinities of this locality are with Sta. 

 Elena, the type-locality of olivaceiceps, rather than with Laguneta in the 

 same latitude but on the western slope of the Central Andes.

 Buthraupis cucuUata Scl. & Salv., P. Z. S., 1879, p. 500 (Concordia). 



This Ecuadorian species occurs in the Temperate Zone of both the 

 Central and Western ranges, but appears to be replaced in the Eastern 

 Andes by B. c. gigas. Our series agrees with topotypical birds from the 

 Quito region.

This well-marked race, or possibly species, of the Temperate Zone of the 

 Eastern Andes was common at El Pinon.

Temperate Zone of the Western and Central Andes. 



Nine specimens from the Temperate Zone of the Central Andes are 

 clearly referable to the Quito rather than Bogota form (eximia). All have 

 a slight trace of blue on the rump indicating the probability of intergrada- 

 tion between these representative races. The Paramillo birds are without 

 blue on the rump. In none of these specimens do the blue lesser wing- 

 coverts cover the black bases of the greater coverts as they apparently do 

 in 'Quito' skins.
