Eastern Andes and eastern slope of the Western Andes of the Subtropical 

 Zone. The occurrence of this form at Rio Toch€ and El Eden, and of P. 

 granadensis at Salento, indicates the faunal affinities of the first-named 

 localities with the Magdalena Valley and of the last with the Cauca 

 Valley. 



Nine males frgm the Magdalena Valley have the crown streaked with 

 scarlet, but a male from La Frijolera in the Lower Cauca region has the 

 crown streaked with cadmium-orange. It thus resembles a male from 

 Tacarcuna in eastern Panama, but in other respects these two males and 

 also two females from eastern Panama (Tacarcuna and Tapaliza) agree 

 with P. o. olivaceus. 



In the color of the crown-stripes these males agree with P. o. flavotinctus 

 of western Panama and Costa Rica, but in the jet blackness of the crown 

 the Frijolera specimen resembles olivaceus, while the Panama specimens 

 show an approach toward flavotinctus. They are'thus intermediate between 

 these two races, instead of olivaceus and panamensis of the Canal Zone as 

 we should expect. In any event it is important to note that representa- 

 tives of olivaceus occur at La Frijolera and at Tacarcuna, while at Peque 

 southwest of the first-named locality Picumnus granadensis antioquensis 

 occurs.

Picumnus olivaceus harterti Hellm., Bull. B. O. C, XXIII, 1909, p. 67 (Paramba, 

 n. w. Ecuador). 



A specimen from Barbacoas agrees with an essentially topotypical 

 series from Esmeraldas southward, in Ecuador, of which five males have 

 the crown-stripes cadmium-yellow. In its more olivaceous color and 

 streaked under-parts this race is much nearer true olivaceus than to canus, 

 its nearest geographical congener. 



It is worthy of note that, as in other cases, the Barbacoas form of this 

 species agrees with the one from Ecuador rather than with the one from the 

 more northern part of the Colombian coast.
