Type.— No. 126670, Am. Mus. Nat. Hist., 1 ad., La Mar (alt. 8260 ft.), Cundi- 
nimarca, Col., June 13, 1913; Manuel Gonzalez. 
Remarks.— This form is based on an adult and immature male from the 
type-locality, and a female from Suba in the Bogoté Savanna. For com- 
parison I have two adult males and one immature female, topotypes of 
analoides from Lima, and four adult males from Ecuador (Chimborazo; 
‘Quito’). The latter agree with analoides rather than with schistacetfrons, 
though in their reduced size and smaller amount of black about the base of 
the bill they show an approach toward the Colombian form. 
In this form the differentiation from C. analis of Bolivia, shown in part 
by C. analoides, is evidently carried to its extreme through the disappearance 
of black about the base of the bill and of the loss of the white speculum.

This Finch appears to be one of the most common and characteristic 
species of the Paramo or Alpine Zone in Colombia and Ecuador, below which 
we have not found it. Ranging from Chile to the Santa Marta Mts., 
Colombia and Andes of Merida, Venezuela, where this zone finds its north- 
ern limit, it is subject to much variation in size. This variation is pro- 
gressive from Peru both northward and southward since, as Sharpe (Cat. 
Bds. B. M., XII, p. 793) shows, specimens from both Ecuador and Chile are 
larger than those from Peru. But from central Colombia northward and 
eastward a decrease in size occurs. In default of series from south of 
Kcuador I can throw no light on variations of this bird in the southern part 
of its range. From Ecuador, however, I have 28 specimens, from Colombia 
34, and from Venezuela, 7. 
In size these 69 specimens obviously fall into two groups. The first in- 
habits the Andes of Ecuador and the Central Andes of Colombia, a natural 
faunal association. The second inhabits the Eastern Andes of Colombia, 
and their extension into Venezuela, and also the Santa Marta group.
