(3354) Polioptila livida plumbeiceps Lawr. 



Polioptila plumbeiceps Lawk., Proc. Acad. N. S. Phila., 1865, p. 37 (Venezuela). 

 Polioptila livida plumbeiceps Hellm., Nov. Zool., XIV, 1907, p. 4 (Venezuela; 

 Bogotd; Cauca Valley). 



A Tropical Zone species which doubtless ranges throughout the greater 

 part of Colombia. We have taken it only in the Magdalena Valley, but 

 Hellmayr {l. c.) records it from the Cauca Vallej-. It is probable that 

 it also occurs at the eastern base of the Andes since we have several speci- 

 mens from the Middle Orinoco. 



It is worthy of note that the Gnatcatcher of the Pacific coast from 

 Esmeraldas southward is a bird of the hilineata group, of Panama, etc., a 

 form as yet unknown from western Colombia.

Polioptila livida daguce Chapm., Bull. A. M. N. H., Vol. XXXIV, 1915, p. 648 

 (Los Cisneros, w. Col.). 



Char, subsp. — ■ Similar to Polioptila I. plumbeiceps (Lawr.) but much darker above, 

 the back, etc., slate-gray rather than guU-gray (No. 7) the inner wing-quills narrowly 

 instead of widely margined with whitish, outer pair of tail-feathers white almost 

 to the base; no indication of a superciliary. 



Known only from the type taken at Los Cisneros in the Tropical Zone 

 of the Pacific Coast.

(3362) Polioptila schistaceigula Hart. 



Polioptila schistaceigula Haet., Bull. B. O. C, VII, 1898, p. xxx (Cachabi, n. w.

A female from San Jose and another from Puerto Valdivia near the 

 Pacific coast are evidently to be referred to this species, hitherto known
