can be no question that G. c. mia^orJiyncha is a perfectly valid 

 form. Cfr. my remarks in Nov. Zool. xii. 1905, p. 9, and I. c. xiv. 

 1907, pp. 42-43. 



Its range extends from the mountains of Colombia south to 

 Northern Bolivia.

Identical with skins from Bogota and Western Ecuador which 

 I am unable to separate from others taken in Mexico and 

 Costa Rica. 



Birds from Bucaramanga form the ti"ansition to C. c. luteola

This bird agrees, in size and colour, with a series from Western 

 Ecuador in the Mvinich Museum. Specimens from Guatemala, 

 which I take to be typical 0. f. funereus, have longer wings 

 (60 mm.) and tail (54 mm.), a slightly larger bill, and the females 

 are much brighter cinnamon underneath. These slight differences 

 might disappear on comparison of a larger series of Central 

 Amei-ican skins, but, for the present, I am unwilling to unite the 

 two forms withovit further evidence. O.f. cethiops, as defined 

 here, ranges over the forest district of Western Colombia and 

 Ecuador. Specimens from Antioquia * and Santa Marta which 

 I have not seen may also be referable to the southern race.
