PIPILO. 409 



We have two skins from the vicinity of the city of Mexico acquired in 1867, con- 

 cerning which, though referred to P. maculatus, we have always had some doubts as to 

 whether they really belong to that species or not. They have a more oHve shade on 

 the upper plumage, and the wing-spots a greenish tint, and the edgings of the wings 

 and tail are more olive-coloured than in more typical P. maculatus. In one specimen 

 the campterium is yellow, in the other just tinted with that colour. We sadly require 

 evidence of the changes of pluamge between adult and young and breeding and winter 

 dress in this and the allied species; but we believe these specimens to be in the 

 breeding-plumage of P. maculatus, those browner in colour and the spots purer white 

 being in winter dress. 



We have placed P. suhmaculatus as a synonym of P. maculatus, as the differences 

 relied upon seem all represented in the series before us. In view of the obvious varia- 

 tions, probably of season and sex, noticeable in this species, we much doubt if the 

 specific distinctness of P. suhmaculatus can be maintained.

We have but little to say about this bird, which seems to be only doubtfully distinct 

 from P. maculatus, and occurs along our northern frontier both in Arizona and in the 

 valley of the Eio Grande.
