Todd-Carriker : Birds of Santa Marta Region, Colombia. 357 



above remarks are based on a comparison of our series with several 

 skins from Brazil and Bolivia, presumably representing true amauro- 

 cephalus, and with the type-series of faustus, kindly loaned by Mr. 

 Bangs. The latter race we consider doubtfully distinct from pileatus. 

 This flycatcher was detected in the lower foothills of the semi-arid 

 section, where it was taken in the fringe of trees along the small 

 streams between Mamatoco and La Tigrera. Specimens were secured 

 also at Fundacion and Tucurinca, while Mr. Smith's collectors took 

 two at Bonda, probably along the Manzanares River.

Mionectes olivaceus galbinus is the brightest in color of all the races 

 of the species, the black being yellowish oil green, with the pileum little 

 darker, and the abdomen pale lemon yellow. In juvenal dress, illus- 

 tiated by two specimens dated July 8 and 21, the color-pattern is the 

 same, but all the colors are duller, and the streaking below obsolescent. 

 If the present series are correctly sexed, as there is every reason to 

 believe, it is evident that the attenuation of the ninth primary is not a 

 sexual character, as has been supposed, since there are numerous ex-
