 (San Agustin, Col.). 



Char. sp. — In the extreme graduation of the tail and dark ohve-green color of 

 the back resembling Atlapetes flaviceps Chapm., but differing from that species in 

 being still darker above (approaching in this respect A. crassus Bangs). 



This distinct species is known only from the region at the head of the 

 Magdalena.

A common bird throughout the Subtropical Zone of all three ranges. 

 Specimens from Fusugasugd, may doubtless be considered topotypical of 

 this form and with them the remaining birds of the series agree in color 

 but average somewhat larger.

 bie et du Perou" = northeast Peru, cf. Berlepsch, Int. Om. Cong., 1910, p. 1097). 



Specimens from the Subtropical Zone in the Western Andes agree with a 

 series from Loja, Ecuador and introduce this race to the recorded Colombian 

 avifauna.

 Buarremon elceoprorus Scl..& Salv., P. Z. S., 1879, p. 504 (Sta. Elena). 



Two topotypes collected by Miller & Boyle show this bird to be a closely 

 related form oi A.l. latinuchiis. Both are males; one in fresh plumage shows 

 the olivaceous tinge which distinguishes this race from latinuchus; the other 

 taken the same day (Nov. 19), is in worn plumage, the olivaceous suffusion 

 of the upperparts has largely disappeared and the specimen can almost be 

 matched by examples of latinuchus.
