difference between new and old skins is greater than that which exists 

 between many subspecies, and if the two sets of birds were from different 

 locahties, might readily be considered racial.

Of general distribution in the Subtropical Zone but apparently not com- 

 mon in the more northern parts of the Western Andes. An old ' Bogota ' 

 skin shows much the same difference from these fresh specimens as exists 

 in old skins of Chlorospingus flavipectiis. Birds from Subia and Fusugasuga 

 are topotypical and the remaining specimens in the series agree with them.

 Pipilopsis flavigularis Scl., Rev. Zool., 1852, p. 8 (New Grenada). 



Inhabits the Subtropical Zone of the Eastern and Central Andes. On 

 the eastern slope of the Eastern Andes it ranges southward at least to south- 

 eastern Ecuador whence we have a typical specimen from Zamora. Speci- 

 mens from La Frijolera northwest Colombia are also typical, but those from 

 La Palma and Andalucia have the breast washed with brownish somewhat 

 as in raarginatus. The throat is orange in four specimens and in the same 

 number yellow.

 p. 189 (Buenavista, Narino, Col.). 



Char, subsp. — Similar to Chlorospingus flavigularis hypophceus but breast and 

 sides light oUve-gray rather than huffy brown, back greener; resembling C. f. 

 flavigularis Scl. but wings and tail shorter, breast and sides browner, flanks more 

 olivaceous, lores grayer, wing-quills margined internally with buff increasing in 

 amount from without inwardly. 



The relationships of this bird appear to be with the Central American 

 form rather than with C. f. flavigularis. Specimens of the latter from the
