proper, but in crossing the Quindio trail from Cartage to the Magdalena 

 Valley we suddenly encountered it in small troupes in the heavy forest of the 

 Subtropical Zone a few hours before reaching Salento. It was last seen on 

 the banks of the Rio Toche at El Pie de San Juan where it was not uncom- 

 mon in bushy growths. 



We did not encounter it in the restricted Bogota region, though we have 

 two 'Bogota' skins in our collection, but on the eastern slope of the Eastern 

 Andes just below Andalucia, Miller secured one specimen, indicating, there- 

 fore, an upper Amazonian or East Andean origin rather than development 

 in the limited area in which it has hitherto been known.

Occurs in both the arid and humid portions of the Tropical Zone of 

 north Colombia, ranging up the Atrato Valley to the headwaters of the 

 San Juan River and up the Magdalena to at least Chicoral, but apparently 

 not reaching the Cauca Valley. 



Specimens from the vicinity of Honda and from Chicoral are doubtless 

 typical. Santa Marta specimens average slightly less blue above and have 

 the bill smaller, while those from the Atrato and lower Cauca Valleys have a 

 slight creamy tint on the white areas indicating an approach toward C. a. 

 zeledoni of Panama.
