Juan Vifias (Carriker). Seven skins. 



In attempting to identify Costa Rican specimens of Sturnella magna, 

 we found them to be much larger than the measurements given by Mr. 

 Ridgway for his inexpectata. Upon comparison of a series of Costa Rican 

 birds with a series of S. m. alticola from Mexico, they were found to be 

 exactly the same, being characterized by the large size and by the yellow 

 malar streak. 



S. m. inexpectata is a lowland form, running down the Caribbean low- 

 lands, probably to some point in Nicaragua, but not reaching Costa Rica, 

 in which country Sturnella is not found on the eastern slope lower than 

 2,000 feet, the birds being restricted to the upper eastern slope, the central 

 highlands and mountains, up to 8,000 feet, and the northwestern Pacific 

 slope and lowlands (Guanacaste). 



S. m. alticola is a bird of the highlands, ranging from the highlands of 

 Chiapas, Mexico, southward through Guatemala (Honduras and Nica- 

 ragua ?), Costa Rica, and Chiriqui. 



It is a common bird in many parts of Costa Rica, wherever there are 

 pastures. It is especially abundant around La Laguna de Coris, or 

 Las Concovas, Laguna de Ochomogo, and in the vicinity of Turrucares, 

 and many are killed by sportsmen.

Unfortunately no females of this species were collected, so that their 

 correct identification is almost impossible. The males are intermediate 

 in size between A. p. sonoriensis and richmondi, and Messrs. Todd and 

 Oberholser in comparing the birds in Washington thought they might be a 

 new form, intermediate between the two above mentioned. There seems
