Eleven were killed at one sliot, but, owing to the difficulty of making 

 presentable skins of such unusually fat birds, I only saved live.

14. Volatinia jacarina (Linn.). 



These pretty little black sparrows were very abundant in small flocks, 

 and seemed to prefer the cactus hedges along the cart-roads. They 

 spend a great deal of their time upon the ground, and lead pretty much 

 the same sort of a life as the little ground doves {Chamwpelia rufipen- 

 nis) so abundant in that region.

 from the western United States, and the size is quite as large as in 

 more northern skins. — R. E.J 



Common at a large lagoon about 10 miles from La Palma, where it 

 probably breeds. The Spaniards call it by a^ name which signifies " an 

 officer," on account of its red shoulder patches.

18. Icterus pectoralis espinachi Nutting (MS.). 



[Note,— Three specimens of this species from the western coast of 

 Costa Rica differ from more northern examples (one each from San Sal- 

 vador, Guatemala, and Tehuantepec) in decidedly smaller size, the 

 wing measuring only 3.70-4,05, and the tail 3,85-4.05, instead of 4,30-

 any tangible differences in coloration. Should the difference in size
