that the record for La Candelaria by Underwood (Biologia) is a mis- 

 take, and should refer either to verreauxi or cassini vinaceiventris. 



It is one of the most abundant pigeons in the Terraba Valley, living 

 under the same conditions as L. verreaaxi, with which it is frequently 

 associated in the same locality. The birds of this genus are not gre- 

 garious, only being met with singly or in pairs.

It is impossible to tell exactly what part of Costa Rica the range of 

 this bird covers, there being but three records of its occurrence. The 

 first known record is that of Lawrence, under G. albiventer, and not 

 the specimens taken by Underwood at Miravalles, as stated by Salvin 

 in a note under that species in Underwood's List. It would seem 

 that the bird is practically confined to northwestern Costa Rica in the 

 region of the volcanoes Miravalles and Tenorio, where, according to 

 Underwood, it is not so extremely rare. The only other record is 

 from Angostura, in the valley of the Rio Reventazon at about 2,000 

 feet. Its habits are evidently similar to those of G. montana. 



I have seen but one slightly immature bird of G. violacea, from 

 South America, and consequently could make no close comparison of 

 that species with the one from Central America, but the close resem- 

 blance of that one skin to Costa Rican birds, combined with the 

 statement made by Messrs. Salvin and Godman (Biologia) that the 

 Central American bird is separated from the Brazilian only on 

 the character of its more vinous forehead and cheeks and by the more 

 intense violet-blue on the mantle, lead me to the conclusion that the 

 Central American bird should be made a subspecies of the Brazilian, 

 as given above.
