seven instead of six) I find that the Cumanacoa bird is separable, and that 

 Lichtenstein's name is a nomen nudum. The name cumanensis, therefore, 

 dates from my publication of it in 'The Auk' though it must be confessed 

 that my object was to show that the bird to which I apphed it was not a 

 valid form! I now name as type No. 73284, Am. Mus. Nat. Hist., Cuma- 

 nacoa, Bermudez, Venezuela, cf , July 5, 1896; W. H. Phelps. 



This form is distinguished by its smaller size and generally darker colors 

 and by the more pronounced and slightly wider, blacker bars on the wing- 

 quills. 



The VUlavicencio specimens agree fairly well with those from Cumana9oa 

 and indicate that this form ranges through Venezuela to the eastern base of 

 the Andes.

Known only from the Tropical Zone of the Pacific coast. Hellmayr 

 (1. c.) describes a specimen from Novita as like others from Ecuador. A 

 female from Tapaliza, eastern Panama extends the recorded range of the 

 species. It is materially grayer than our two Colombian specimens, but is 

 in much worn plumage.
