BIRD LIFE IN THE URUBAMBA VAIXEY OF PERU. 93 



(28S0) ANAERETES PARULUS AEQUATORIALIS Berlepsch and Taczanowski. 



Anaereles parulus aequatorialis Berlepsch and Taczanowski, Proc. Zool. Soc, 

 1884, p. 296 (Gechce, W. Ecuador). 



There is remarkably little variation in this species, it being possible 

 to match specimens from Chile with others from Ecuador. When, 

 however, comparable series are examined, it appears that birds from 

 Colombia, Ecuador, and Peru have the crest less developed and not so 

 black, the back averaging browner, the forehead and nape less 

 streaked with white, the orbital and auricular region less black. In 

 the Urubamba Valley this bird was found chiefly in the Subtropical 

 Zone; in Colombia it reaches the Temperate Zone.

(2884) ANAERETES FLAVIROSTRIS Sdater and Salvin. 



Anaeretes flavirostris Sclater and Salvin, Proc, Zool. Soc, 1876, p. 355 (Tilotilo, 



Bolivia). 



This is apparently a Temperate Zone representative of Anaeretes 

 parulus. Our specimens agree with others from Bolivia.

(2885a) ANAERETES AGRAPHIA Chapman. 



Anaeretes agraphia Chapman, Proc Biol. Soc. Wash., vol. 32, 1919, p. 263 (Idma, 

 9,000 feet, near Santa Ana, Peni). 



Specific characters. — Quite unlike any described species of the genus, 

 but most nearly resembling Anaeretes agilis Sclater, from which it 

 differs in having no streaks above or below, the crest wholly black, etc. 



Known only from the type, taken by Heller above Idma, at an alti- 

 tude of 9,000 feet. This is probably, like A. agilis, a species of the 

 Temperate Zone. 



(2888a) MIONECTES STRIATICOLLIS POLIOCEPHALUS Tschudi. 



Mionectes poliocephalus Tschudi, Faun. Per., 1845-46, p. 148, pi. 9, fig. 1 (Peru, 

 ' ' tief em Waldregion " ) . 



Inhabits the Subtropical Zone. Differs from a topotypical series 

 of true stnaticollis of Bolivia, in having the white streaks of the 

 throat less extended on to the breast; the sides and flanks less heavily 

 streaked, the center of the belly somewhat deeper yellow and v/ith 

 fewer streaks; the plumbeous of the head more sharply defined, par- 

 ticularly on the sides of the neck, from the olive-green behind it. The 

 Peruvian bird is intermediate between the Bolivian and Colombian 

 forms, but dilTers sufTiciently from both to be recognizable.
