We have the type of Swainson's Pipilo fuscus before us ; it 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. alUgula 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. mesoleucm is said to be found in the upper 

 Eio 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. alhigula 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 Lichten stein 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
