These specimens differ fi-om a good scries of T. n. nigricapilhis 

 from Western Ecuador in having the black cross-bands of the 

 lower parts much broader, more regular as well as more closely 

 set, especially along the middle of the belly. Moreover, chin 

 and throat are distinctly, though narrowly, banded with blackish, 

 v/hile they are uniform white in the Ecuadorian form. Even 

 young birds can easily be distinguished by these characters. In 

 the coloration of the lower parts T. v. schottii approaches 

 T. semibaclms Salv., of Chiriqui and Costa Rica, but has the to]) 

 of the head black like 7'. n. nigricapillus. Its range is evidently 

 i-estricted to Westei'n Colombia, fiom the R. Ti'uando south to 

 the San Juan district. -Like its southern representative, it 

 exclusively lives in the hot, low country.

t The presence of dusky bars on tlie primary coverts npon wliich the late 

 Dr. Sharpe laid much stress is a purely individual character. Five birds from 

 W. Ecuador aU have distinct blackish bars, as also the female from Juntas.
