as can be judged by the specimens before me, are narrower and darker 
than usual in the other forms, thus producing the more uniformly brown 
appearance. Six specimens before me give the following dimensions.

Peuceza ruficeps australis, new subspecies. SOUTHERN 
SPARROW. 
Type, No. 136131, U. S. Nat. Museum, Dept. Agric. coll., 2, City of 
Oaxaca, Oaxaca, June 15, 1894, Collected by E. W. Nelson and E. A. 
Goldman (Orig. No. 2104). 
Distribution. That outlying part of the Mexican table-lands occupied 
by the Valley of Oaxaca, and adjacent mountains up to 6000 or 7000 feet. 
On the north its range merges into that of doucardz, which is common 
about the Valley of Mexico and on the plains of Puebla. 
Description.— Similar to P. boucardz, from which it differs in the light 
rusty-red shade of the rufous on the dorsal surface, the small amount of 
ashy bordering the feathers of the back, and the more fulvous lower 
surface. 
In general coloration it is much nearer scotte of Chihuahua 
and southern Arizona, but the rufous of australis is of a paler or 
more rusty shade, and it is smaller with a heavier bill. The 
present form is at once distinguishable from /zsca (of this paper) 
by the very much lighter shade of the red or rusty color on the 
dorsal surface.
