R. costariceiiais seems to be an entirely local species, difteving 

 from R. passer/nii\ of which species the Museum possesses a 

 large series from various localities, both on the Atlantic and on 

 the Pacific sides of the Cordillera, including Pozo A/ul where 

 the two arc found in company. Pozo Azul is situated about thiity 

 miles southwest of San Jose, just at the foot of the hills where 

 the level belt of the Pacific coast begins. For this reason and 

 from the fact that I have not met with the bird in the extensive 

 series of specimens I have examined from the Atlantic region, I 

 am inclined to believe it a species confined to the southwest 

 coast region. 



I would here express my thanks to Mr. J. C. Zeledon for kind 

 suggestions in regard to the present paper. 



THE BIRDS OF ANDROS ISLAND, BAHAMAS. 



BY JOHN I. NORTHROP. 



The island of Andros is the largest of the Bahama group, 

 being about ninety miles long, and forty or fifty miles across at 

 the widest part. The southern portion is separated from the 

 northern by shallow waters called 'bights' ; but these are so filled 

 with cays, as to make it convenient to include all the islands 

 under the general name of Andros. 



Like all the others of the group, Andros is entirely of coral for- 

 mation. The country is described by the natives as either 'cop- 

 pet', 'pine-yard,' or 'swash.' The first term is applied to the 

 thicket of angiospcrmous trees and shrubs that occupies the ritlge 

 along the eastern coast. In most places, this belt is very narrow, 

 but near the southern end it extends several miles into the inte- 

 rior. Back of the coppet, the land is comparatively level, and is 

 covered by a forest of the Bahama Pine {/Vf/?/s haha77ic7tsis) . 

 As one approaches tiie west coast, the pines become smaller and 

 are mingled with palmettos ; finally both cease, and one sees
