ON SOME BIRDS FROM THE SIERRA NEVADA DE 

 SANTA MARTA, COLOMBIA. 



BY OUTRAM BANGS. 



Mr. W. W. Brown, Jr., has recently sent a third lot of birds, 

 including about three hundred skins, to the Bangs collection. 

 These specimens were collected during Ma)' and June, 1898, at 

 the following localities in the Sierra Nevada de Santa Marta, 

 Colombia: Palomina, altitude 5000 feet; San Francisco, 6000 

 feet; San Miguel, 7500 feet; and Macotama, 8000 feet. Many 

 of the birds are in worn breeding plumage, and some of the 

 species are also represented by young in first plumage. Again 

 I am in debted to Mr. R. Ridgway and Dr. C. W. Richmond for 

 aid in determining many species. 



(Note.— All measurements are in millimeters. Colors, when definite 

 names are used, are according to Ridgway 's Nomenclature of Colors.)

Specific characters.— This species resembles in a general way the only 

 other member of the genus — N. erythrops Scl. of Lima, Peru, but differs 

 much in details of coloration and markings— lower abdomen white in- 

 stead of dusky brown ; lower flanks and under tail-coverts, uribam d, pale, 

 cinnamon instead of blackish ; under wing-coverts white, some of the 

 feathers faintly streaked with dusky, instead of " dusky brown narrowly 

 barred with white."

 maries) bistre; primaries hair brown, narrowly edged with bistre; tail 

 bistre, the center and base of the feathers shading towards hair brown ;
