Xiphorhynchus oequatorialis insolitus ' (Ridgw.) of which I have ex- 

 amined the type and a specimen from the Rio Truando, is more deeply 

 colored than any of our Colombian specimens (though approached by one 

 from Baudo and another near Quibdo) and appears to be more unlike wqua- 

 torialis than is the more northern punctigula (Ridgw.), some specimens of 

 which are very close to oequatorialis.

(2543) Xiphorhynchus triangularis (Lafr.).

Common in the Subtropical Zone of all three ranges. I detect practi- 

 cally no racial variation in our series of forty-eight specimens, though those 

 from the Western and Central Andes may average slightly more rufescent 

 above. The white area along the cutting-edge of the central part of the 

 maxilla to which Hellmayr (P. Z. S., 1911, p. 1154) calls attention is present 

 in all but five of our specimens. Two of these are from Cocal, one from 

 Anolaima, near Bogota, one from Fusugasuga, and one from Buena Vista. 

 I do not regard the absence of this character in the Cocal birds as indicating 

 intergradation of triangularis with cequatorialis, which doubtless occurs at 

 a few hundred feet below Cocal. In other respects these two Cocal birds 

 are typical triangularis having the throat feathers margined or ringed in 

 squamate pattern, the crown with shaft-streaks. Furthermore, in three 

 other specimens from Cocal the whitish mark on the maxilla is conspicuous, 

 while its absence in specimens from the Bogota region shows that it is not 

 a constant character.
