ant spots, and below these again, a large dark spot partially covered "by the 

 feathers, and not observed in specimens of P. fusca. The middle of the 

 breast and abdomen clear white, the rusty of crissum extending further on the 

 belly. The bill is more rounded and shorter, the tarsus shorter, and the outer 

 claw extends further on the middle claw. 



Pipilo aberti is easily distinguished by the black lores and chin, less distinct 

 spots on the throat, and nearlj r uniform under parts. 



A specimen collected by Mr. Clarke, of the Mexican Boundary Survey, at 

 the Copper Mines, appears to belong to this species. It has unfortunately lost 

 its tail. The chestnut patch is paler. A smaller race of the same was col- 

 lected by Lieut. Couch at Santa Catarina in Mexico. 



Centurus uropygialis, Baird. 



Head and neck all round, and the lower parts of the body brownish ash, 

 darkest above ; a broad frontal band of dull yellowish white, (not golden.) A 

 small quadrate patch directly on the vertex, of deep red ; rest of the upper parts 

 banded transversely with black and white, even on the rump and upper tail 

 coverts. Middle of the belly yellow, sides of the body along crissum, and lower 

 tail coverts banded with black and white, like the back. Primaries black, white 

 at the base ; secondaries with round spots on the outer web ; two central tail 

 feathers black on the outer vane with a narrow stripe of white at the base, 

 running for half the length of the feather near the shaft, and tapering to a point ; 

 inner vane banded alternately with black and white ; two exterior feathers on 

 each side banded on both vanes ; intermediate ones entirely black. 



Total length 9 inches, extent 16, wing 5, tails 4 l-10th. 



Differs from C. carolimcs in yellow belly, resembles it in character of trans- 

 verse bands above, and markings on the tails. C. flaviventris has the middle 

 tail feathers entirely black, and the rump and upper coverts white. C. 

 tricolor has the middle of belly red. C. uropygialis also lacks the golden front 

 and occiput of this and other species.
