blackish chocolate, the former predominating, the markings generally 

 covering the greater part of the surface of the eggs. In some sets, 

 however, the markings are much less abundant; covering less than 

 half the surface."

Although the amount of variation in shade of color in this species 

 is certainly remarkable, ranging in the case of the adult male from 

 deep glaucous green to forget-me-not-blue, it seems impossible to 

 correlate these differences with geographic areas. Both extremes 

 occur in the present series. In juvenal dress, represented by speci- 

 mens dated May 31, June 7, and August 7, both sexes resemble the 

 adult female, but are much duller throughout, the pileum duller green 

 than the back, while the under surface is extensively yellowish buffy, 

 obscurely streaked with dusky. Two males from the Heights of 

 Chirua and San Miguel, dated March 21 and 25 respectively, are prob- 

 ably in first nuptial dress. The outer primaries and the tertiaries 

 have been renewed, and are blue-edged; the remaining remiges are 

 green-edged. The rectrices are all blue-edged in one, but only the 

 outer ones in the other. Both have the back more or less tinged with 

 green. 



This beautiful little tanager is found only in the heavy Subtropical 

 Zone forest between 4,000 and 6,000 feet, and is most abundant on the 

 slopes of the San Lorenzo, being very rare in the Sierra Nevada. It 

 is almost invariably seen in small flocks, together with other species 

 of similar habits, feeding in the tree-tops. Next to T. desmaresti, 

 it is the most abundant species of the genus in this region, and it seems 

 odd that Mr. Brown did not meet with it. Most of Mr. Smith's speci- 

 mens came from Valparaiso (now called Cincinnati).
