AUGUST, 1915. NOTES ON SOUTH AMERICAN BIRDS CORY. 305 

 Chrysoptilus punctigula zulias subsp. nov. 



Type from Encontrados, Zulia, western Venezuela. Adult male, 

 No. 34632, Field Museum of Natural History. Collected by N. Dear- 

 born, February 14, 1908. 



Similar to C. p. punctipectus from Cumana, Venezuela, in general 

 coloration of upper parts, but differs in having the throat much blacker, 

 the white spots being much smaller, and the under parts, except middle 

 of lower abdomen, with rounded black spots somewhat approaching 

 C. p. guttatus from northern Peru. It differs from C, p. guttatus from 

 Peru in its much more olive and less golden green back with smaller and 

 narrower black bands on the upper parts; smaller white spots on the 

 throat, and lack of reddish tinge on the lower throat and upper breast 

 (the last character may vary with age). From C. p. ujhelyii and 

 C. p. striatigularis it may be distinguished at a glance by its spotted 

 (not streaked) throat, more heavily banded upper parts, and other 

 characters. 



Wing, 99; tail, 70; bill, 21; tarsus, 18 mm. 



This apparently well marked subspecies inhabits the heavily wooded, 

 low, humid region in the vicinity of Encontrados and Catatumbo. 

 Two females from La Ceiba, Trujillo, Venezuela, while not typical 

 approach close to this form. Specimens examined from Venezuela: 

 Encontrados, Zulia, 20", 4$; Catatumbo, 2 $ ; La Ceiba, Trujillo, 

 2 9 (not quite typical). 



For convenience of ornithologists the following key to the group 

 is submitted:
