516 U. Ss. Pp. R, R. EXP. AND SURVEYS—ZOOLOGY—GENERAL REPORT. 
The specimens exhibiting the highest development of claw are from Fort Tejon, but the other 
localities raentioned illustrate the same peculiarity very readily. Specimens frequently occur, 
however, which it is difficult to refer positively to any one of the three species with spotted 
scapulars ; some of them may possibly be hybrids.

PIPILO ABERTII, Baird. 
Pipilo abertii, Barrp, Stansbury’s Rep. Great Salt Lake, Zoology, June 1852, 325. (New Mexico.) 
Kieneria abertii, Bonar. Comptes Rendus, XL, 1855, 356. 
Sp. Cu.—General color of upper parts pale brownish yellowish red ; beneath brighter, especially en the under coverts, palest 
on the middle of the belly. Sides of head anterior to eyes, and chin dark brown. Bill yellowish. 
Length, 9 inches ; wing, 3.70; tail, 4.85. 
Hab.—Base of Rocky Mountains in New Mexico. Valley of Gila and Colorado. 
This plainly colored bird is among the largest of the North American species, and is without 
any blotches, spots, or variations of importance from one color, except on the chin and sides of 
the head. The bill is similar to that of P. erythrophthalmus, but the cutting edge is less concave 
and more sinuated. The tail is more graduated ; the claws thicker and stronger. The wings 
are short and much rounded ; the first quill shorter than the secondaries.
