no form of this species is known from the Tropical Zone of the Pacific coast 

 of Colombia but that in the Tropical Zone of the Pacific coast of Ecuador 

 it is represented by C. r. rubripileus Salvad. and Fest., a smaller form in which 

 the throat is usually spotted quite to the base of the bill, the rump paler, 

 the outer tail-feathers quite as often barred as not (barred in ten out of eigh- 

 teen specimens) while the female has less red in the crown. 



A female from La Candela in the Central Andes at the head of the Mag- 

 dalena Valley, exhibits in a most interesting way the characters of both 

 gularis and rubiginosus, and although not a geographical intermediate, it 

 suggests the intergradation of these forms. It has the throat spotted with 

 white and well-defined black malar stripe and unbarred rectrices of gularis, 

 but the crown is gray, the red being confined to the nuchal region; the rump 

 is nearly the color of the back and the breast is narrowly barred with buffy 

 as in rubiginosus. 



Specimens from the Central Andes are larger and have the abdominal 

 region and under tail-coverts less definitely barred than in those from the 

 Western Andes. The minimum size appears to be reached at the type- 

 locality, whence a female measures, wing, 125; tail, 75.5; culmen, 26 mm.; 

 as compared with wing, 115; tail, 70; culmen, 24 mm. in females from San 

 Antonio. Specimens from La Frijolera are intermediate in size.

Char, subsp. — Similar to C. r. meridensis, but upperparts and olive bars of 

 underparts darker, cheeks grayer, bill longer; similar to C. r. canipileus (d'Orb.) 

 but with much more red and consequently darker, less golden in color. Similar to 

 C. r. alleni (Bangs) but olive bars of underparts wider and yellowish ones narrower; 

 tail always (?) unbarred; posterior underparts, especially lower tail-coverts, less 

 distinctly barred.
