Descriptions of New Species of American Birds. 477 



Collected by Col. A. J. Grayson. No. of type, 42,562. 



Remarks. — This Partridge, in its general appearance, 

 resembles 0. pectoralis, but is rather larger, it specially differs 

 from that species, in there being no black before the eye, and 

 in having a narrow black collar below the white throat, 

 instead of a large black patch extending on the breast as in 

 0. pectoralis. I consider it but a well-merited compliment to 

 name it after its discoverer, who continues his explorations 

 at localities seldom visited.

"This species, as far as I can ascertain, is undescribed, and 

 is interesting as being the most northern representative of the 

 genus yet discovered. It approaches the Saltator ntftventris 

 of Yigors (S. vigorsii of Gray, and, perhaps, of Bonaparte, 

 Notes Ornith. 23), and considered perhaps jnstly to be a 

 synonym of S. grandis, but appears to be lighter below, the 

 abdomen and crissum by no means rufous, and the super- 

 ciliary stripe extending far beyond the eye ; it resembles 

 typical specimen of grandis in the absence of clear olivaceous 

 on the back and wings ; it is, however, much paler beneath,
