°i8q7 I Nelson, JVeiv Birds from Mexico and Guatemala. 6q 



Heleodytes occidentalis, new species. Colima 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, 

 H. jocosus, this species maybe 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 '\r\ jocosus, 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., $, 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 lighter than the nape. Light markings on 

 exposed part of wing are same shade as 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. 



If. humilis rufus differs from humilis 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.
