A series of 9 specimens from Costa Rica and 1 from Veragua, com- 

 pared with exactly the same number of D. erythropygia Scl., from Mex- 

 ico (1), Guatemala (7), Panama* (1), and Rio Truando, Colombia (1), 

 agree constantly in the characters above pointed out, and likewise 

 from three examples of D. triangularis from Bogota (2) and Guayaquil 

 (1). The Veragua specimen is like those from Costa Riea, except that 

 it has the whole forehead decidedly russet (the streaks pale tawny), pro- 

 bably only an accidental or individual character. 



-f-Dendrocolaptes puncticollis Scl. & Salv. 



A specimen in the Lafresnaye collection (No. 2214) in the Boston So- 

 ciety, labeled » Dendrocolaptes albicollis Vieill., y'g, Bahia," is much like 

 I). puncticollis, Scl., but is evidently distinct from that species. It 

 certainly is not 1). picumnus (Licht.), D. validus (TsCH.), D. certhia 

 (Bodd.), norD. sanctithomw (Lafr.), with all of which it has been com- 

 pared; nor does it agree with the characters ascribed to I), radiolatus 

 Scl. & Salv., B. intermedins Berl. (also from Bahia), D.plagosus Salv. 

 & Godm., D.pallescens Pelz., I), undulatus (Cab.), nor 1). concoldr'PELZ., 

 descriptions of which have been carefully consulted. 



Compared with an example of what seems to be B. puncUcollis from 

 Costa Rica (No. 42158, $ , Navarro, Feb., 18GG; J. Cooper), it is found to 

 differ so much as to iorbid its reference to that species, though it is 



*Au adult male iu the collection of the Costa Rica National Museum (No. 2333, Sau 

 Carlos, December 20, 1888, A. Alfaro) has the Spanish equivalent of the following 

 inscribed ou the label: Iris, dusky; feet, blue; upper mandible, black j lower, white. 



Mam unable to Hud the slightest difference between this Panama example and 

 some skins from Guatemala and Mexico.
