in its turn, is not distinguishable from Guiana skins. I am perfectly 

 convinced that the birds inhabiting Guiana, Venezuela, and Colombia 

 belong to one and the same form, entitled to the name browni. But 

 whether they are different from P. citrina, of eastern Brazil, appears 

 extremely doubtful. Compared with three males from Brazil (includ- 

 ing the types), the northern birds are slightly smaller, with shorter 

 tails, and somewhat slenderer, shorter bills. It may be, too, that the 

 ear-coverts are more greenish, and the under parts a deeper, purer yel- 

 low. However, a larger series of the typical race should be examined. 

 Furthermore, the name Orospina pratensis Cabanis (from Tucuman) 

 may be an earlier one for browni, for the single (not quite adult) 

 male from Argentina more nearly agrees with the northern race in 

 proportions."

It will thus be seen that the name browni rests on a very slender 

 basis indeed, but pending the receipt of a series of Brazilian examples 

 it may be allowed to stand provisionally. In a series of males secured 

 at Minca from June ly to 26, 1913, two phases of coloration are repre- 

 sented. Some are decidedly grayish above, while in others the back 

 is almost as bright olive yellow as the crown. 



This bird is found throughout the foothills and mountain slopes 

 up to 6,000 feet, wherever grass-lands or savannas occur. It has been 

 seen in the little bits of savanna along the road to Cincinnati, between 

 Mamatoco and Minca, but it is not at all common there. While col- 

 lecting at Minca the writer was so fortunate as to find a considerable 

 flock feeding in a tract of recently cleared level land in the valley, 

 though their normal habitat in that vicinity was evidently some grass- 

 covered hills near by known as the " Cueva de Tigre." The birds are 

 extremely shy, flushing at the slightest provocation, and flying far and 

 high. Their flight is Goldfinch-like, but rather stronger. In their 

 habits they remind one a great deal of the Longspurs, alighting almost
