 the occiput, and another from the angle of the lower mandible running upon the 

 side of the neck, white, space between those lines including the nares and 

 plumage under the eye and the ears, nearly black. Throat from the base of the 

 bill, black, which color is bounded on each side by the white lines from the angles 

 of the lower mandible, and continues to a somewhat rounded point upon the breast. 

 Head and body above dark cinereous, inclining to brownish upon the back and 

 wing coverts. Quills brownish. Tail brownish black, external feathers having 

 their outer webs pure white and tipped with the same color, the brown color of 

 these feathers extending narrowly along the shafts into the white tips. Body

Hab. Texas, on the Rio Grande; discovered by Mr. John Woodhouse Audubon, 



Obs. This is one of the most remarkable finches yet discovered in America, 

 and is quite unlike, even in general appearance, any other species of this country 

 with which I am acquainted This bird was also brought from Texas by Mr. 

 Audubon. 



4. Emleriza Belli, nobis. 



Form. Wings rather short, second, third and fourth quills longest and nearly 

 equal. Tail and legs rather long. 



Dimensions. % Total length of skin from tip of bill to end of tail about 5i 

 inches, wing 2|, tail 3 inches. 



Colors. % Head and neck above cinerous, shading into olive upon the back 

 and neck. 



Frontal spots on each side of the base of the bill, (scarcely united) narrow 

 ring around the eye, and entire under surface white. Edge of the wing at flexure, 

 yellow ; superior wing coverts brown tinged with ferruginous, quills and tail 

 brownish black, nearly all the feathers of both narrowly edged with whitish, 

 most apparent upon both webs of the external tail feathers. Conspicuous spot 

 upon the breast, nares, and lines from the external angles of lower mandible 

 running downwards upon the sides of the neck, deep brownish black. Flanks 

 tinged with rufous and with a few longitudinal stripes of brown. 



% Slightly smaller, flanks and interior tail coverts more tinged with rufous. 



Hab. California, near Sonoma and San Diego; discovered by Mr. John G. 

 Bell. 



Obs. This species resembles in rather a remarkable degree the Emberiza 

 hypochondria, D'Orb. Voy. Merid. Ois- pi. 45, fig. 1, but is smaller and without 

 the deep castaneous flanks of that species. In the bird now described, the dark 

 spot upon the white breast is a striking feature, and is much more strongly pro- 

 nounced than in any other with which I am acquainted. 



I have named this species in honor of Mr. John G. Bell, of the city of New 

 York, a gentleman possessing a very extensive knowledge of natural history, and 

 whose attachment to the pursuit of which, induced him to make the visit to Cali- 

 fornia, which resulted in the discovery of this and other iateresting birds.
