We have the type of Swainson’s Pipilo fuscus before us; if agrees with other 
Mexican specimens, the species being apparently confined in its range to Mexico and 
the bordering States on the north, the allied forms P. crissalis and P. albigula being 
fairly definite. Sumichrast says of this species that it is common in the plateau of 
Mexico, where it breeds; it is also found in smaller numbers in the alpine region, but 
it does not descend below 4000 feet ®. Grayson found it abundantly about Tepic and in 
many places on the road to Guadalajara. It does not approach the sea-coast nearer 
than Tepic, where it is a constant resident ’. 
The bird described by Prof. Baird as P. mesoleucus is said to be found in the upper 
Rio Grande valley, that of the Gila and Colorado®, and at Guaymas in the Gulf of 
California. Specimens from these countries have the occiput slightly more rufous than 
examples from Mexico; but in this respect the type is intermediate, and we think all 
should be united under the name of P. fuscus. P. albigula is very nearly allied, but 
has less rufous on the lower abdomen. P. crissalis is distinct in having no white on 
the middle of the abdomen.

Though briefly described by Lichtenstein in his list of the Mexican birds collected 
by Deppe, we have no doubt that this species is identical with that subsequently 
described by Mr. Sclater as Pipilo albicollis*®; it has since been regarded by American 
authors as an extreme variety of P. fuscus, from which we understand that they 
anticipate links may be found connecting the two birds. In this view we cannot 
agree, for we consider P. rutilus to be a thoroughly segregated form, to be distinguished 
by its much whiter under surface, by the peculiar ferruginous bar across the throat, 
and by the colouring of the chest. 
In its range it appears to be confined to a limited district in Southern Mexico, for
