Inhabits the Tropical Zone. There is an obvious an(i fairly con- 

 stant difference separating bir(is from southern Peru and Bolivia 

 from those of southeastern Ecuador (Zamora) and southeastern 

 Colombia. The more southern birds have the dark centers of the 

 feathers of the back smaller, and their margins much gra3^er, less 

 olivaceous than the northern birds. These characters are not so 

 noticeable in worn specimens but are usually diagnostic. The Zamora 

 birds doubtless typically represent aurifrons aurifrons, and I assume 

 that Bonaparte's name is applicable to the southern form. In addi- 

 tion to the Urubamba specimens listed below, we have examples of 

 peruana from the following locahties: Peru: Rio Inambari, 1; Rio 

 Javari, .3; Astillero, 1; Candamo, 1; La Pampa, 2. Bolivia: Todos 

 Santos, Province of Cochabamba, 1 ; Yungas, Province of Cocha- 

 bamba, 2. 



Rio Comberciato, 1; Idma, 1; Santa Ana, 1.

Ollantaytambo, 1 male; Chospiyoc, 2 males; Huaracondo Canyon, 

 1 male, 1 ?; Poquiura, 1 female; Pisac, 1 male; Galea, 1 male, 1 female; 

 Cuzco, 1 male, 2 females; La Raya, 1 female. 



(3882) BRACHYSPIZA CAPENSIS PERUVIANA (Lesson). 



Pyrgita peruviana Lesson, Rev. Zool., 1839, p. 45 (Lima, Peru). 



An abundant species ranging from the Pacific coast to the table- 

 land, but on the eastern slope we did not take it below the Subtropical 

 Zone. Our series appears to agree with specimens from Lima. 



San Miguel Bridge, 3; Idma, 1; Torontoy, 1; Ollantaytambo, 2; 

 Huaracondo Canyon, 2; Ttica-Ttica, 4; Cuzco, 6; Calca, 1 ; La Raya, 6. 



(3903) PSEUDOCHLORIS OLIVASCENS CHLORIS (Tschudi). 



Sycalis chloris Tschudi, Faun. Per. Aves, 1846, p. 216.— Sclater and Salvin, 

 Proc. Zool. Soc, 1869, p. 153 (Tinta). 



Inhabits the Puna Zone. Specimens from Tirapata, taken in late 

 July and early August, are completing the molt and are consequently 

 in fresh plumage. A male which is evidently fully adult is bright 

 olive-yellow above, the rump and upper tail coverts being nearly 

 pure yellow. A second male has the back washed with brownish, 

 but the upper tail coverts are nearly as bright as in the first-named 

 male. A male from Pisac (April 18) is in worn plumage and differs 

 so widely from either of the Tirapata birds that it is difficult to believe 

 they represent the same species. While wear might change the back
