by its more rufous dorsal surface, which is entirely of a warm rufous 

 brown. The superciliary line and the rest of the sides of the head are 

 marked as in the other species. The sides of the neck and breast are 

 ashy, and the flanks and under tail-coverts are fulvous brown, brighter 

 than in the other forms. The rest of the lower parts are white. The 

 wings and tail are longer, the bill is about the same. 



A specimen of Hemiura taken by us at Acapulco is indistinguish- 

 able from Yucatan specimens, representing brachyura^ so the 

 present species is probably not widely spread along the west 

 coast of Mexico.

Wren. 



Type, No. 143007, U. S. Nat. Museum, Dept. Agric. coll., J, Jico, Vera 

 Cruz, Mexico, June 24, 1893. Collected by E. W. Nelson (Orig. No. 1272). 



Distribution. — Both coasts of Mexico north of the Isthmus of Tehuante- 

 pec, in the heavy forests of the mountain slopes of the ' tierra templada.' 

 There are specimens in the collection from the Sierra Madre near Chil- 

 pancingo, Guerrero ; Mt. Zempoaltepec, Oaxaca, and Jico in Vera Cruz. 



Description of type. — Entire top of head, neck and back with upper 

 tail-coverts rusty rufous, a little duller on the head but showing no 

 marked contrast between that and back; exposed parts of folded wings 

 and tail similar to back and crossed by fine blackish bars; lores dark 

 grayish ; superciliary stripe white with fine black edgings to feathers ; 

 postocular stripe blackish ; feathers of ear-coverts and sides of throat and 

 neck with white shaft-lines and black borders, producing a bright black 

 and white striped pattern; chin and throat whitish; breast dark ashy; 

 fianks, abdomen and under tail-coverts dark rufous. 



The ashy-breasted Wrens of this genus, in Mexico and Guate- 

 mala, have been constantly referred to certain South American 

 species. In Baird's ' Review of American Birds' he gives 

 Heterorhiiia griscicoUis as questionably from Guatemala to Mexico. 

 Salvin and Godman in the ' Biologia Centrali-Americana,' Vol. I, 

 p. 80, unite all the Mexican and Central American birds of this 

 style under Henicorhina kucophrys Toch. Having a considerable 

 series of these birds before me from numerous Mexican localities, 

 in addition to the U. S. National Museum series from Central 

 America, I find no difficulty in recognizing three distinct forms
