Heleodytes occidentalis, new species. CoLImMA WREN. 
Type, No. 142863, U.S. Nat. Museum, Dept. Agric. coll., @, Sierra 
Nevada de Colima of Jalisco, Mexico. April 20, 1892. Collected by E. 
W. Nelson (Orig. No. 102). 
Distribution. — Oak forest at the base of the Sierra Nevada de Colima 
on the border between the states of Colima and Jalisco. 
Description. — Compared with typical examples of its nearest relative, 
HI. jocosus, this species may be recognized by its reddish brown crown 
and the brighter markings of the dorsal surface, and also by the obsole- 
scence of the last dark bar on the outer end of the outer tail-feather. The 
postocular stripe is reddish brown instead of blackish as in jocosws, and 
the flanks and under tail-coverts are marked and shaded with bright 
fulvous. The ventral surface is less heavily spotted with black, and its 
bill is proportionately shorter and stouter. The two species are of about 
the same size. 
Heleodytes humilis rufus, new subspecies. GUERRERO 
WREN. 
Type, No. 142820, U. S. Nat. Museum, Dept. Agric. coll., 2, Aguahui- 
zotla, Guerrero, Mexico, December 28, 1895. Collected by E. W. Nelson 
and E. A.Goldman (Orig. No. 2456). 
Distribution.— Interior of Guerrero along lower slope of the Sierra 
Madre near Chilpancingo. 
Description.— Feathers of forehead and crown black, with borders of 
dark rufous becoming richer and redder on nape, back and sides of neck. 
Thence the entire back, including rump and upper tail-coverts, is over- 
laid with rusty brown a little lighterthan the nape. Light markings on 
exposed part of wing are same shadeas back. Chin, throat and ear-coverts 
white ; breast and middle of belly white, washed with pale fulvous ; entire 
flanks and under tail-coverts dull fulvous. 
FT, humilis rufus differs from humélis of the coast districts of 
western Mexico, of which I have a good series at hand, in the 
greater intensity of the rufous on the dorsal surface, and in the 
greatly added intensity of the fulvous wash below. 
The differentiation of this form agrees with certain topographic 
and climatic differences between the localities inhabited by it and 
those inhabited by the typical one.
