heaviness of the stripes below, but it appears to be individual and I can 

 detect no racial difference between topotypical (Bogota region) skins and 

 those from the Western and Central Andes. Old 'Bogota' skins have the 

 back notably browner, less olivaCeous above than our recently collected 

 ones.

Two specimens from La Morelia and two from Florencia in the Tropi- 

 cal Zone of Amazonian Colombia, show on comparison with a specimen of 

 brevicauda from British Guiana, the characters attributed to the Peruvian 

 race by Taczanowski. The posterior parts of the upper surface, and the 

 exposed portion of the inner wing-quills, are decidedly less rufous and more 

 olivaceous, the breast is more heavily margined and the size considerably 

 less, as the appended measurements of males show:

Found only at Villavicencio where Fuertes shot two specimens and 

 Cherrie one. This appears to be a representative of G. b. brevicauda with 

 which it doubtless intergrades.

Inhabits the Temperate Zone of all three ranges. Our series of fifteen 

 specimens (including four from Mt. Pichincha) shows much variation in 

 color, some being rich ochraceous-tawny, others nearer ochraceous-buff 

 below with a corresponding difference above. This variation, however, 

 appears to be individual rather than racial. Both types of color are found
