Inhabits the Tropical Zone of the Pacific coast and eastward to the 

 Magdalena. Our Pacific coast specimens agree with others from Panama 

 which Hellmayr (/. c.) fixes as the type-locaUty, but a female from the 

 Magdalena Valley (Malena) is much paler below than any one of eight 

 females from Panama and western Colombia.

Found at one station in the Tropical Zone of the Pacific coast and also 

 on the lower Cauca. The Puerto Valdivia specimen agrees essentially 

 with the type and other Panama specimens. Those from Barbacoas have 

 a less well-defined, unspotted, chestnut-rufous area posterior to the breast.

A pair from the Amazonian Tropical Zone adds this species to the known 

 avifauna of Colombia. The male differs from two lower Orinoco (Suapure) 

 males in having the breast and abdomen centrally barred with black, the 

 female differs from a lower Orinoco female in having the hazel-brown throat 

 area more restricted and less definitely bordered by a black line. These 

 differences may be racial but the material at hand is not, in my opinion, 

 conclusive (see Cherrie, Bull. A. M. N. H., XXXV, 1916, p. 185). Rhopo- 

 terpe torquata tragicus Cherrie {I. c.) based on a female from the Rio Roosevelt 

 appears to differ from torquata chiefly in its wider and more extensive white 

 wing-bar.

 curos, e. Peru). 



Four specimens were secured in the Tropical Zone of Amazonian Co- 

 lombia. Three have the forehead black while in the third (immature?) 

 it is rufous of the same color as the back. All four specimens may be easily 

 distinguished from any one of twelve specimens of colma from the lower
