Compsothlypis pitiayumi elegans Todd, Ann. Cam. Mus., VIII, 1912, p. 204 

 (Tara Mt.; Venezuela). 



Parvla pitiayumi, Wtatt, Ibis, 1871, p. 322 (Cocuta Valley) . 



Inhabits both the Tropical and Subtropical Zones, but has not been 

 recorded from the humid Pacific coast fauna. Specimens from the Western 

 and Central Andes have, on the average, less white on the wing-coverts 

 than those from the Eastern Andes but in size agree with elegans. Speci- 

 mens from Quetame in the Eastern Andes are typical of elegans, which 

 appears to be not only more deeply colored below but is also a shade darker 

 above than pitiayumi, of which we have eight specimens from Matto Grosso.

(3619) Compsothlypis pitiayumi pacifica {Berl.). 



Parula pitiayumi pacifica Bbbl., P. Z. S., 1884, p. 286 (Surupata, Ecuador). 



A male from Ricaurte (alt. 4500) in southwestern Colombia in its small 

 size and the restriction of white on the wing-coverts agrees with the Ecua- 

 dorian form (of which we have ten specimens), while our other Colombian 

 birds are referable to the Venezuelan form. It will be observed therefore 

 that the two races most nearly related, that is, -pacifica of Ecuador and 

 spedosa of Chiriqui and northward, are apparently not connected geographi- 

 cally, there being as yet no form of this group known from the Pacific coast 

 between Barbacoas and Chiriqui, while the bird inhabiting the mountains 

 of western Colombia is referable to C. p. elegans of northeastern South 

 America.
