vian form. The northern bird is somewhat larger (wing, 65 mm. in four 

 males from San Antonio, 60 mm. in two from Inca Mine, Peru) but agrees 

 in color with the southern one, about an equal amount of variation in the 

 coronal patch and color of the underparts being shown by both series.

Sometimes reaches the lower border of the Temperate Zone and is com- 

 mon in the Subtropical Zone of the Western and Central Andes and of the 

 western slope of the Eastern Andes. Our series of forty-one specimens 

 shows but little individual and apparently no racial variation and agrees 

 with a single specimen from Inca Mine, Peru.

 Andes, and one from Villavicencio essentially agree in color with a series 

 from Trinidad, but have the upperparts and auricular region slightly darker, 

 a difference possibly due to fading in the Trinidad specimens, though the 

 latter were taken in 1893. The Buena Vista specimens are materially 

 different from old Bogota and Guiana (?) skins in which the upperparts are
