(1809) Picumnus granadensis granadensis Lafr. 



P[icumnus] granadensis Lapr., Rev. Zool., 1847, p. 78 (Cali, Col.). 



Picumnus canus Bangs, Proc. Biol. Soc. Wash., XXIII, 1910, p. 72 (Naranjito, 

 R. Dagua). 



Picumnus oUvaceus granadensis Hbllm., P. Z. S., 1911, p. 1189 (Primavera, 5200 

 ft., San Isidro; Media Luna, 2700 ft. ; San Antonio; Rio Dagua). 



Inhabits the Tropical Zone of the Pacific coast, north of Barbacoas, and 

 the Cauca Valley, ranging upward to the Subtropical Zone in the Western 

 Andes and western slope of the Central Andes. Represented at the northern 

 end of the Western Andes by P. g. antioquensis. The occurrence of the 

 olivaceous races {olivaceus, panarriensis, harterti) at the east, north, and 

 south of the range of this species, the absence of intergrading specimens, 

 and its strongly marked characters indicate the specific distinctness of this 

 form. Furthermore, its stability is indicated by its occurrence in the humid 

 coast region (Cisneros, etc.) and in the comparatively dry Cauca Valley 

 (Rio Frio) without apparent change. On the other hand, we have yet to 

 find granadensis and one of the three forms mentioned above associated; 

 they have, however, been found in the same faunal area. Thus, at Bar- 

 bacoas we have taken the richly-colored P. olivaceus harterti and at Cisneros 

 wholly typical examples of granadensis with whitish, comparatively un- 

 streaked underparts and grayish back. If, therefore, granadensis is a 

 representative form of olivaceus we should have the palest form occurring 

 in what is doubtless the most humid portion of the area concerned. To my 

 mind it does not follow that granadensis is a representative form of olivaceus 

 merely because it occurs in an area where no other species of Picumnus is 

 foimd which could be so considered. Western Colombia is so often with- 

 out forms common to Ecuador and Panama, northern and central Colom- 

 bia, that the absence of some form of olivaceus between the ranges of P. o. 

 olivaceus and P. o. harterti need not surprise us.

(1809a) Picumnus granadensis antioquensis Chapm. 



Picumnus granadensis antioquensis Chapm., Bull. A. M. N. H., XXXIV, 1915, 

 p. 640 (Peque, W. Andes, Antioquia, Col.). 



Char, subsp. — Similar to P. g. granadensis but whole breast grayish, the flanks 

 and abdominal region distinctly streaked. Differs conspicuously from all the races 

 of P. olivaceus in being less yellow throughout.
