292 Bangs, Birds from Western Costa Rica. [j^ 



Columba nigrirostris Scl. Four adults, both sexes, Boruca, Paso Real 

 and Pozo del Rio Grande, May, July and August. 



Chgemepella minuta (Linn.). Forty specimens, adults and young of 

 both sexes, Paso Real, July. 



Although recorded from southern Mexico and Guatemala, and again 

 from Panama, this little dove has, so far as I know, not before been taken 

 in Costa Rica. 



Chsemepella rufipennis rufipennis (Bonap.). Twenty-three specimens, 

 both sexes, young and adult, Boruca, Pozo del Rio Grande and Barranca, 

 April -July. 



Clara vis pretiosa pretiosa Ferrari-Perez. Twenty-five specimens, both 

 sexes, Boruca, Paso Real and Pozo del Rio Grande, April-August. 



Leptotila verreauxi Bonap. Twenty-one specimens, adults and young, 

 both sexes, Boruca, Paso Real, Pozo del Rio Grande and Barranca Punta- 

 renas, April- August . 



Leptotila rufinucha Scl. & Salv. Thirty-three specimens, adults and 

 young of both sexes, Boruca and Pozo del Rio Grande, April, May and 

 August. 



Geotrygon montana (Linn.). Nineteen adults, both sexes, Boruca 

 and Pozo del Rio Grande, April-June. 



After very careful comparison of a large amount of material I can find 

 no constant differences between birds of this species from the Greater 

 Antilles and from the continent. Mainland specimens perhaps average 

 a little darker in color, although many are indistinguishable from island 

 skins in this respect; they also average just a trifle smaller, but not enough 

 so to be appreciable in comparing single individuals. 



Psittacid.e. 



Ara macao (Linn.). One adult female, Pozo del Rio Grande, April 20. 



Brotogerys jugularis (Milll.). Thirteen specimens, both sexes, Paso 

 Real, Pozo del Rio Grande and Barranca Puntarenas, July, April, and
