Spiza americana (Gmel.)

Type from Santa Marta, Colombia, No. 5371, $ adult, coll. of E. A. 

 and O. Bangs. Collected Jan. 15, 1898, by W. W. Brown, Jr. 



Subspecific characters. Smaller than A. conirostris; wings and tail 

 darker, more dusky, less greenish ; back much grayer, the feathers 

 tipped and edged with gray ; nape and head between the black stripes 

 clear gray without any olive or greenish. 



Size. tf adult, wing, 76.2; tail, 64.6; exposed culmen, 14; 9 adult, 

 wing, 66; tail, 57; exposed culmen, 14. 



Remarks. A. conirostris canens differs so much in color from true A. co 

 nirostris besides being considerably smaller, that it may prove to be a dis 

 tinct species, though for the present I prefer to treat it as a subspecies. 



Saltator magnus (Gmel.) 



1 specimen, adult <j\ This one example is not at all typical, and if 

 others from the same region are found to agree with it, the form deserves 

 separation as a subspecies.
