throat, flanks and under tail-coverts light citron yellow, palest on the 

 throat. Females in juvenal plumage resemble males in the same 

 plumage.^ 



The colors from an adult male taken June 28th were: eye seal; 

 bill, above black, below plumbeous; feet slate grey. A male just 

 assuming the adult phase had the bill above slate black, below slate 

 grey with blackish tip. 



In the series in the Brooklyn Museum and the Klages specimens 

 in the American Museum the . yellow on the crown is about inter- 

 mediate in amount between that on the crown of B. chlorotica liolacei- 

 coUis from Chapado Matto Grosso,^ and E. trinitatis^ from Bonda, Santa 

 Marta, Colombia. The Santa Marta birds probably represent a dis- 

 tinct race. 



In the American Museum collection are specimens, sent by Klages, 

 collected on the Caura River, during September and December, and 

 from Ciudad Bolivar on the Orinoco collected in December. My 

 own notes show that specimens were collected at various points on 

 the Orinoco from March to August inclusive. 



A nest and set of three fresh eggs together with the mother bird 

 was collected at Agua Salada de Ciudad Bolivar April 17, 1907. The 

 nesting site was a Chaparo oak in the midst of a savanna that was 

 dotted thinly with trees. The nest was located near the tip of a long 

 horizontal branch and only about 1.4 m. from the ground. In 

 shape it is a flattened ball and is constructed entirely of dry grasses, 

 of medium texture loosely woven into shape and is without other lin- 

 ing. The entrance is a round hole in the middle of one side. The 

 nest rested on the main branch and two small horizontal twigs that 

 proceed from opposite sides of the main branch, the result being a 

 cross-shaped support. It was not tied in any way to the supporting 

 branches and certainly gave one the impression that it was very inse- 

 cure. My thought at the time of finding it was that with the first puilf 

 of wind it would go tumbling to the ground. The measurements are: 

 horizontal diameter about 15 cm., vertical diameter about 10 cm.; 

 the entrance hole is 3.5 cm. in diameter. The eggs are from ovate 

 to medium short-ovate in form. They measure 15.5 x 12.25; 17-75 ^ 12 



lAn examination of the specimens of Tanagra in the collections of the American Museum and the 

 Brooklyn Museum, together with a consideration of my field notes and observations convinces me that 

 our greatest advance in knowledge of the specific character of the various members of the group will result 

 .from a careful, systematic study of age and seasonal plumages correlated with field observations.
