Bangs Birds from Costa Rica and Chiriqui. 



107 



0. cinereicuuda seems to be a perfectly distinct species. Trochilus caslan- 

 eovenlris Gould is, furthermore, the name by which the bird of the Volcan 

 de Chiriqui, which I have called throughout this article, for the sake of 

 clearness, 0. leucaspis, must be known. It was based on a female bird from 

 the Cordillera of Chiriqui, and is the earliest name for any member of the 

 genus. I should therefore arrange the forms as follows : 



Oreopi/ra castaneovenlris ccutaneoventris (Gould.) Volcan de Chiriqui. 



0. castaneoventris calolsenia (Salv.) Costa Rica ; Irazii, Cerro de la Candel- 



aria, Dota Mts. (one skin in Underwood coll.), etc. South to western 



ranges of Veragua. 

 (0- pectoral'i s Salv. A doubtfully valid form, occurring with 0. c. calolsema 



in several parts of Costa Kica, the alleged differences probably being 



due to fading or to some aberrant difference in structure of the 



feathers.) 

 0. chiereicauda, Lawr. Central Costa Rica. Dota Mts. 



Melanerpes wagleri Salv. & Godm. 



In the Underwood collection is one young male of this species, taken at 

 Pozo Azul, July 9, 1903. This is I believe the first time the bird has been 

 recorded from Costa Rica, where the place of this Panaman form is taken 

 by Melanerpes hoffmanni. 



Hypocnemis nrevioides capnitis subsp. nov. 



Type from Volcan Miravalles, Costa Rica. cT adult. No. 17,048, coll. of 

 E. A. and O. Bangs. Collected October 16, 1895, by C. F. Underwood. 



Characters.- Similar to H. nseviuide** (from Panama) except that the 

 adult c? has the whole sides and flanks slate color. (In true //. ntevioides 

 (Lafr.) the sides are whitish tinged with pale gray, and flanks pale grayish 

 brown). 



The adult 9 of the new form has the sides and flanks darker, duller 

 brown, and the back deeper chestnut, than in true H. nsevioidcs. 



MEASUREMENTS. 



Mr. W. W. Brown, Jr., took'examples of true H. nsevioides (Lafr.) at Loma 

 del Leon, and near Panama City, Panama, but did not meet with the 

 species anywhere in Chiriqui, and so far as I am aware H. nxvioides has 

 never been recorded from Veragua or Chiriqui, there being, apparently, a 

 gap between the ranges of the Costa Rican and Panaman forms. 



* Type locality, Pasto, southwestern Colombia.
