.»,; Heleodytes capistratus nigricaudatus, new subspecies. 

 Black-tailed Wren. 



Type, No. 142S06, U. S. Nat. Museum, Dept. Agric. coll., <J, San Benito, 

 Chiapas, Mexico, March 11, 1896. Collected by E. W. Nelson and E. A. 

 Goldman (Orig. No. 3648). 



Distribution. — Pacific coa.st of Chiapas, near Tapachula, and thence into 

 adjacent parts of Guatemala. 



Heleodytes capistratus /lii^^ricaiidatus is very much like If. capis- 

 tratus castaneus Ridgw. in the uniform chestnut coloration of the 

 back, and, indeed, in other respects except the color of the tail. 

 In the present form the two central rectrices are black, or blackish 

 brown, with one and sometimes two subterminal white or whitish 

 bars, the feathers being tipped with a narrow grayish or blackish 

 brown border and lacking the several brownish bars which are 

 conspicuously present in birds from Costa Rica, Nicaragua and 

 Guatemala. In the eleven specimens of nigricaudatus before me 

 this character is so constant that, despite the close resemblance 

 of this form to castaneus in other particulars I feel justified in 

 recognizing it as a geographical race occupying the extreme north- 

 western border of the range of the species along the Pacific coast. 



Salpinctes obsoletus neglectus, new subspecies. Chancol 



Rock Wren. 



Type, No. 142866, U. S. Nat. Museum, Uept. Agric. coll., $ , Hacienda 

 Chancol, Guatemala, January 3, 1896. Collected by E. W. Nelson and E. 

 A. Goldman (Orig. No. 3330). 



Distribution. — Highlands of western Guatemala and probably of central 

 Chiapas. 



Description.— Salpinctes o. neglectus maj' be distinguished from the 

 Rock Wrens of the western United States and the highlands of northern 

 and central Mexico by its clearer or more ashy gray color, the intensity of 

 the black .shaft-lines and white tips of the feathers on the dorsal surface, 

 the black and white markings being quite clearly and sharply defined. The 

 ear-coverts are dark brown, the cheeks are white with blackish brown 

 mottling, and the sides of the neck are brown, variegated with white. 

 The rump is a little deeper fulvous than in obsoletus from the Mexican 

 highlands. The tail is also darker than in that bird. The throat is 

 whitish, the breast and sides are mottled with distinct black spots, and the 

 flanks are dull fulvous. Size about the same as typical obsoletus.
