Swains, and E. pulverius Brewst. From the former it may be 

 distinguished by its duller, grayer color, especially on under- 

 parts. From E. pulverius it differs mainly in its much smaller 

 size and rather darker, grayer color. We secured seven specimens 

 of this bird on the highlands of Chiapas, Mexico, and Guatemala, 

 where it is probably resident. The distribution of the three fly- 

 catchers named above is as follows : 



Empidonax pulverius Brewster. — Pine forests of the Sierra 

 Madre of western Mexico from Chihuahua to Jalisco. Zacatecas, 

 and across to Tamaulipas. 



Empidonax affiuis Swain. — Pine-forested slopes of mountains 

 on southern border of the Mexican tableland from the Valley of 

 Mexico to Mt. Orizaba and the Sierra Madre of Guerrero. 



Empidonax trepidus. — Pine-forested slopes of the highlands 

 in Chiapas and Guatemala. 



Phcenicothraupis littoralis, new species. Tabasco Ant 

 Tanager. 



Type No. i66,2oS, $ ad., U. S. National Museum, Biological Survey 

 Collection. From Frontera, Tabasco, Mexico, collected March 4, 1900, by 

 E. W. Nelson and E. A. Goldman. 



Distribution. — PVoni heavy coastal forests of Tabasco north to 

 southern Tamaulipas. 



Subpecific characters. — The adult male differs from P. salvi)ii vaTnnXy 

 in its much more vivid poppy red underparts, especially on throat and 

 breast ; upperparts clearer, more vinaceous red ; crest deeper richer scar- 

 let, Tlie females differ still more, having a strong reddish suffusion on 

 underparts with distinct traces of red crest on crown. Size about as in 

 P. salvini but bill larger. 



Dimensions of type. — Wing, 105; tail, 92 ; culmen, 19; tarus, 28. 



Notes. — True F. salvini appears to be a bird of the forested 

 foothills being replaced in the lower coast lowlands by the species 

 described above. At first I proposed to treat this bird as a sub- 

 species of P. salvini, but in view of the absence of any specimens 

 showing intergradation between the widely different females of 

 the two it is probably safest to consider them as full species until 

 the contrary is proved.
