An abundant species in the Subtropical Zone of the Western and Cen- 

 tral Andes, descending to the Tropical Zone, but not taken below 2000 ft. 

 It appears to be rare in the Eastern Andes. 



I have no Paraguay specimens for comparison but our series agrees with 

 a single bird from Chapada, Matto Grosso.

A single male from La Morelia lacks the grayish rump-patch and is • 

 obviously to be referred to the Amazonian form which, while it has not 

 before been recorded from Colombia, has been reported from eastern Ecua- 

 dor by Hellmayr.'

Common in the Tropical Zone of the entire Magdalena Valley and also 

 at the eastern base of the Eastern Andes at Villavicencio, and doubtless 

 as far south as the junction of llanos with Amazonian forest, where it is 

 replaced by S. r. ruficollis, which Miller secured at La Morelia. 



In the region between the Magdalena and Cauca Valleys intergrades 

 occur, most of which are nearer uropygialis but some of which are very 

 close to wqualis. While the differences between the two are obvious, there
