Description. — Pileum with two broad lateral stripes of black, 

 extending from the forehead to the nape, and inclosing a median 

 coronal spot or stripe of deep orange rufous or Sanford's brown; 

 sides of head (including broad superciliaries) and of neck deep 

 neutral gray, with a blackish transocular stripe, fading into pallid 

 neutral gray on the throat; upper parts, and wings and tail exter- 

 nally, between dark citrine and medal bronze ; under parts, from the 

 breast down, lemon chrome, the sides shaded Avith pyrite yellow, the 

 crissum sometimes more buffy (near old gold) ; under wing-coverts 

 dull yellowish whit^; bill brownish black: feet pale brownish (in 

 skin). 



Measurements.— Mal^iWrng, 70-77 (average. 72); tail, 57-64 

 (61); bill, 11-12 (11.3); tarsus, 21.5-24 (22.5). Female: Wing, 

 63-70 (66); tail, 53-59 (56); bill, 10.5-11.5 (11.2); tarsus, 21-22 

 (21.5). 



Range. — Subtropical Zone, Andes of central and southern Peru, 

 south to the Urubamba Valley. 



Remarks.— Imm2it\iv& birds of this species may readily be told by 

 the rusty tips to the greater wing-coverts and by the olive greenish 

 nape and sides of the head. 



In its pattern of coloration and proportions this species is a typical 

 Basileuterus. The black transocular stripe is not mentioned in the 

 original description nor shown in the plate, the colors of which are 

 poor. The type specimen, kindly placed at my disposal by Dr. Otto 

 Fiihrmann of the Neuchatel Museum, was exposed to the light for 

 many decades, so long in fact that its original colors appear to have 

 been considerably changed. Indeed, it actually agrees better with the 

 Ecuador race about to be described than with Peruvian specimens, 

 but Doctor Hellmayr, who has again examined it at my request, is 

 confident that this is due entirely to post-mortem changes in the skin. 

 He points out that von Tschudi did not extend his travels in Peru 

 beyond the Department of Junin toward the north. There is noth- 

 ing on the label of the type to show whence it came, other than 

 " Perou," but in his Fauna Peniana von Tschudi expressly gives the 

 type locality as " Urwiildern des Chanchanayo [sic] gebietes," i. e., 

 Chanchamayo Valley. Freshly collected specimens from this general 

 region agree with the description as given above. There is some 

 variation in the color of the upper parts, but not more than in the 

 other races of this species, which appear to be sufficiently well 

 differentiated.
