that the form of mttellinu found at Puerto Valdivia is much paler than that 

 of the Pacific coast.

Char, suhsp. — Resembling M. m. dbditivus in color but wing and tail averaging 

 slightly longer, the wing more pointed, the chin feathers ('beard') shorter, broader, 

 and less stiffened; differing from M. to. manacus in its grayer underparts, unbarred 

 nape and more pointed wing. 



Inhabits the Tropical Zone at the eastern base of the Eastern Andes.

(3174&) Manacus manacus bangsi Chapm. 



Manacus manacus bangsi Chapm., Bull. A. M. N. H., XXXIII, 1914, p. 625 

 (Barbacoas, Col.). 



Char, svhsp. — Resembling M. m. gutturosus (Desm.) in color, the throat and 

 jugulum white clearly demarked from the deep. guU-gray breast and abdomen, but 

 wing longer and more pointed, tail shorter, outer primaries narrower less regularly 

 ciu-ved and projecting 8 to 10 mm. beyond the tips of secondaries. 



This race appears to have a very restricted range. No form of the 

 species has been recorded from the Pacific coast of Colombia north of Bar- 

 bacoas nor have we met with one in -the Cauca Valley. To the south 

 its range can extend but a short distance since at Esmeraldas, Ecuador 

 southward, the quite different M. m. leucochlamys (Bull. A. M. N. H., 

 XXXIII, 1914, p. 626) is found.

Apparently restricted to the upper Magdalena Valley where it appears 

 to represent M. m. abditivus of the lower part of the valley. As remarked 

 under that race specimens from Malena, from near Medellin, and Puerto 

 Valdivia show, in possessing a faint tint of yellow on the anterior under- 

 parts and nape, an evident approach toward fiaveoliis. The difference 

 between the two forms is further bridged by three specimens from the 

 vicinity of Honda which are much less strongly tinged with yellow than are
