This species appears to be restricted to the arid northern coastal zone.

Inhabits the Temperate Zone in all three ranges. A male collected at 

 El Pifion just south of Bogota, is much less rufescent above and more ru- 

 fescent below than two 'Bogota' skins in the Museum collection. The 

 latter are bright amber-brown above with the jugulum and center of the 

 breast grayish, while the El Pinon specimen is uniform ochraceous-bufi 

 below. It thus more nearly resembles S. g. rufipectus in general color than 

 it does the Bogota specimens which I assume represent true gularis. One 

 of the latter has indeed been compared with Lafresnaye's type which it 

 resembles but has the breast somewhat paler. Not one of eight specimens 

 from the Western and Central Andes in Colombia and three from near 

 Quito are so bright as these two 'Bogota' specimens, but the occurrence at 

 El Pinon, in the heart of the Bogota region, of a specimen which is essen- 

 tially like those of the Western Andes indicates either that two forms occur 

 in the Eastern Andes or that the two Bogota skins are not normally colored 

 arid have perhaps undergone some change in color since collected. I in- 

 cline to the latter rather than the former theory and therefore enter my 

 Synallaxis gularis rufipectus as a synonym of S. g. gularis.

Synallaxis rutilans caquetensis Chapm., BuU. A. M. N. H., XXXIII, 1914, p. 621 

 (Florencia, Col.). 



Char, subsp. — Similar to S. r. amazonica HeUm., but the rufous areas much 

 deeper (mahogany-red rather than cinnamon-rufous) less extensive below, and more 

 extensive above, where they occupy most of the crown and back; flanks and abdomi- 

 nal region olive-fuscous with a sUght tint of the color of the breast, rather than bufiy 

 brown. 



This well-marked race is known only from Amazonian Colombia.
