while the forehead is the bluish green; but in the other, a male, the yellow

 in panamensis it is whitish.

Inhabits the Temperate Zone of the Central and Eastern Andes descend- 

 ing to the upper limits of the Subtropical Zone. A specimen from Laguneta 

 in the Central Andes agrees with others from El Pifion in the Bogota region 

 in having the pinkish crown reaching to behind the eyes, whereas in Ecuador 

 specimens it is restricted to the forehead. 



The Ecuador bird will stand as Pionus seniloides gerontodes (Finsch).'
