Nov. 1907. BIRDS FROM GUATEMALA DEARBORN. 125 



green above and wax-yellow beneath, and all had straw-colored 

 irides. The Puerto Barrios bird was olive-gray above, and only 

 locally and slightly tinged with yellow beneath, and had dark-brown 

 irides. The dark iris was an index of immaturity, and it seems proba- 

 ble that the color variation so conspicuous in any large series of this 

 species is due to difference in age, the pale specimens being younger 

 than those of brighter color. 



245. Vireo bellii Audubon. 



Bell's vireos do not appear to have been heretofore recorded from 

 south of Tehuantepec, but apparently they reach southern Guatemala 

 in considerable numbers. Two were taken at Gualan February i5th, 

 two at San Jose, March 8th, and one at Patulul March 25th. No 

 evidence of a recent moult is discernible on any of the lot. Iris dark 

 brown. 



246. Vireolaniqs melitophrys Du Bus. 



One specimen, the only one seen, was taken at Lake Atitlan. 

 Iris Nile-blue. 



247. Vireolanius pulchellus Sdater & Salvin. 



This species was found only in the wooded valleys near Patulul, 

 but even there it was scarce. Two specimens were collected. Iris 

 dark brown. 



248. Cyclarhis flaviventris Lafresnay. 



Nine were collected, in all; one at Mazatenango, five at Patulul 

 and three at Lake Atitlan. The song of this bird is rather loud, smooth 

 and pleasant to hear. Iris orange, and elliptical in shape, with the 

 longer axis horizontal.
