(2319) Synallaxis subpudica Scl. 



Synallaxis subpudica Scl., P. Z. S., 1874, p. 10 (Bogotd); Stone, Proc. Acad. 

 N. S. Phila., 1899, p. 306 (Ambalema). 



We met with this species only on the Bogota Savanna, and hence in 

 the Temperate Zone of the Eastern Andes, but Stone records it from Am- 

 balema, in the Magdalena Valley. 



Bogota Savanna, 7. 



(2320) Synallaxis pudica pudica Scl. 



Synallaxis pudica Scl., P. Z. S., 1859, p. 191 (Bogotd); Scl. & Salv., P. Z. S., 

 1879, p. 521 (Remedios). 



Inhabits the Tropical Zone of the Magdalena Valley and westward 

 into Antioquia, ascending in clearings or along trails into the lower border 

 of the Subtropical Zone.

(2320a) Synallaxis pudica nigrifumosa Lawr. 



Synallaxis nigrifumosa Lawb., Ann. Lye. N. H. N. Y., VIII, 1867, p. 181 (Grey- 

 town, Nicaragua). 



Synallaxis pudica Hellm., P. Z. S., 1911, p. 1148 (Sipi; Pueblo Rico). 



Inhabits the Tropical Zone of the Pacific coast of Colombia. Speci- 

 mens from this region average somewhat larger than those from Nicaragua 

 and are slightly grayer below and less intensely olivaceous above. They 

 are, however, nearer to true nigrifumosa in the color of the parts named 

 than they are to pudica, while the tint of chestnut-rufous of the crown and 

 wings is alike in Nicaraguan, Costa Rican, and west Colombian specimens. 

 In short, while not wholly typical, specimens from the Pacific coast region 

 of Colombia are nearer to the Central America, than to the Bogota form.

(23206) Synallaxis pudica caucse Chapm. 



Synallaxis pudica caucce Chapm., Bull. A. M. N. H., XXXIII, 1914, p. 622 (La 

 Manuelita, Cauca Valley). 



Char, subsp. Similar to S. p. pudica Scl., but the crown is paler, cinnamon- 

 rufous rather than chestnut-hazel; the back mouse-gray without the olivaceous 

 wash of pudica, the rump and upper tail-coverts dark grayish olive, paler than in 

 pudica.
