Carriker : List of the Birds of Costa Rica. 507 



Bangs Collection : San Pedro and Escazu (Underwood). 

 Fleming Collection : San Pedro and Los Cuadros de Irazu (Under- 

 wood).

 Carnegie Museum : Volcan Irazu, Paso Real de Terraba, and Peralta 

 (Carriker); Tucurriqui (Underwood). Four skins. 

 Boucard was the first to see this handsome large swift in Costa Rica, 

 but did not secure specimens of it. It seems rather strange that it 

 was not taken by the early collectors, because it is by no means rare, 

 although very hard to shoot. I have seen it in all parts of the country 

 from near sea-level up to the craters of the Volcanoes de Irazu and 

 Turrialba. I have never been able to find out where they breed, but 

 having always seen the birds around the summits of volcanoes during 

 the beginning of the breeding season, it seems not improbable that they 

 have their nests in the cliffs of the inner walls of the craters. 



219. Chaetura vauxi (Townsend). 



Cypselus vauxi Townsend, Jour. Acad. Phila., VIII, 1839, 148. 



Chcetura vauxi Baird, Birds N. Am., 145, 1858, pi. 18. — Hartert, Cat. Birds 

 Brit. Mus., XVI, 1892, 481 (Honduras, most southern record). — Salvin 

 and Godman, Biol. Centr.-Am., Aves, II, 1893, 375 (Costa Rica [Van 

 Patten, in U. S. Nat. Mus.l). 



British Museum Collection : Los Cuadros de Laguna, July, 1898 ; 



Carrillo, Nov. 7, 1898 (C. F. Underwood). 



The only published record for the occurrence of this swift in Costa 

 Rica is that in the Biologia, which is the record of a skin collected by 

 Van Patten, without locality. Mr. Ogilvie-Grant informs me, how- 

 ever, that there are two skins in the British Museum collected by 

 Underwood, as given above. This is evidently a very rare bird in Costa 

 Rica, being merely a straggler, but perhaps more abundant than the 

 records tend to show, on account of the difficulty of collection.
