(3804) Saltator atripennis atripennis Scl. 



SaltatoT atripennis Scl., Proc. Acad. N. S. Phila., 1856, p. 261 (Popayan); 

 Scl. & Salv., P. Z. S., 1879, p. 505 (MedeUin); Hbllm., lUd., 1911, p. 1120 (Pueblo 

 Rico, 5200 ft.). 



Common in the Subtropical Zone of the Western Andes; one specimen 

 from the western slope of the Central Andes. 



Popayan birds are topotypes and the others, except those from Ricaurte 

 and Barbacoas, agree with them. 



Five specimens from Ricaurte (alt. 4500 ft.), a locality near Barbacoas 

 where the coastal forest ends, and one from as low even as Barbacoas, are 

 fairly intermediate between this form and the next.

(3804a) Saltator atripennis caniceps Chapm. 



Saltator atripennis caniceps Chapm., Bull. A. M. N. H., XXXIII, 1914, p. 182 

 (Fusugasugd,, Col.). 



Char, suhsp. — Similar to <S. a. atripennis but crown largely gray instead of 

 largely black; exposed portions of inner tertials wholly olive-green, throat and 

 breast with no wash of buffy, under tail-coverts paler, bUl averaging heavier and 

 more inflated laterally. 



Inhabits the Temperate Zoneof the Eastern Andes and southward into 

 Ecuador (Gualea). It is not surprising therefore to find that five specimens 

 from Ricaurte (alt. 5000 ft.), a locality in southwestern Colombia on the 

 Ecuadorian line, are intergrades. The bill in these Ricaurte birds agrees 

 with that of caniceps, the color of crown more nearly resembles that of 

 atripennis while the tertials are more like those of caniceps. The buffy 

 throat-mark is barely evident in four specimens and absent in one, but the 

 cinnamon-buff under tail-coverts are unquestionably those of atripennis. 



The present case furnishes an exception to the rule that the affinities of 

 west Ecuadorian forms are with those of the Cauca region rather than with 

 those from the Bogota region.

Found only in the arid coastal region of the Lower Magdalena and lower 

 Atrato.
