Hah. North America, Eio Grande valley. — Mexico, Nuevo Leon {Couch^). 



This species was first described as long ago as 1851 by Mr. Lawrence from specimens 

 obtained by Capt. J. F. M'Cown in the valley of the Rio Grande. Subsequent obser- 

 vations tend to show that its range is nearly restricted to that district. It has been 

 stated to extend to Southern Mexico ; but Mr. Ridgway has shown that the bird from 

 that region is separable by fairly pronounced characters, though his giving it a third 

 name indicates that he expects intermediate forms to be extant connecting the two. 



Mr. Sennett and Dr. Merrill had abundant opportunity of observing E. rufivirgata in 

 the valley of the Lower Rio Grande at Loraita and elsewhere. They found a number 

 of its nests and eggs ; the former are domed, and often placed in the heart of a bush 

 from two to five feet from the ground ; the nest is nearly round, and made of dried 

 stems of weeds, pieces of bark, grasses, and leaves, sometimes with a little hair for 

 lining, but more frequently without. The eggs, four in number, are of a pure dull 

 white colour.

Hob. Mexico, Cordova {SalU ^), temperate and hot regions of Vera Cruz {Sumichrast ^), 

 Play a Vicente {Boucard ^). 



The Embernagra of Southern Mexico differs from E. rufivirgata in having a much 

 stouter bill, the flanks deep drab or raw-umber brown, and the crissum deep fulvous ^. 

 The bird is altogether of a stouter build. 



Sumichrast states that this species inhabits the hot and temperate regions, and is 

 found in the latter as high as 4000 feet above the sea *. 



3. Embernagra superciliosa.
