(2895) LEPTOPOGON SUPERCILIARIS SUPERCILIARIS Tschudi, 



Leptopogon superciliaris Tschudi, Arch, fiir Naturg., 1844, vol. 1, p. 275 (Cen. 

 Peru). — Berlepsch and Stolzmann, Ornis, 1906, p. 86 (Idma). 



Our specimens are less yellow below than Colombian specimens of 

 poUocepTutlus; have the plumbeous cap more restricted, the wing- 

 coverts less ochraceous. The differences are carried to the extreme in 

 a series from Locotal, Bolivia, which, however, may well stand with 

 the Peruvian race.
