This, the palest form of the group, appears to be restricted to the Cauea 

 Valley. It is one of the comparatively few races confined to that region. 

 La Manuelita, 3; below Miraflores, 2; CaU, 1; Guengiie, 1. 



(2321a) Synallaxis gujanensis columbianus Chapm. 



Synallaxis gujanensis columbianus Chapm., Bull. A. M. N. H., XXXIII, 1914, 

 p. 620 (Buena Vista, Col.). 



Char, subsp. — Similar to S. g. gujanensis (Gm.), but the forehead grayer the 

 underparts much whiter, the breast very faintly tinted with grayish instead of 

 strongly washed with warm buff; the sides and flanks rather warm grayish ohve 

 instead of tawny-oUve; auricular region grayer. 



Inhabits the Tropical Zone at the eastern base of the Eastern Andes.

Synallaxis fuscifrons Madab., Orn. Monatsber., 1913, p. 22 (Aracatuca, Santa 

 Marta, Col.). 



Leptoxura cinnamomea Wtatt, Ibis, 1871, p. 331 (Paturia). 



Synallaxis dnnammnea Allen, Bull. A. M. N. H., XIII, 1900, p. 158 (Cienaga). 



This is evidently a form of the northern coastal region, which, however, 

 extends up the Atrato to Bagado. It may easily be distinguished <from 

 true cinnamomea by its much brighter color and olive-gray forehead. 



Bagado, 2; Atrato, 1; La Playa, 2; Calamar, 2.

 P. Z. S., 1879, p. 521 (Dept. Antioquia); Hellm., Ihid., 1911, p. 1148 (Tatamd 

 Mt., 6700 ft.). 



Apparently of local distribution in the Subtropical and Temperate 

 Zones. We did not meet with it in the Central Andes. Specimens from 

 the Western Andes have stouter bills but otherwise agree with those from 

 the Eastern Andes.
