BASILEUTEETJ8. 175 



In Mexico as yet we only know Sasileuterus lelli as an inhabitant of the temperate 

 highlands of the southern portion of the republic. Prof. Sumichrast records it from 

 the temperate regions of Vera Cruz, beyond the limits of which it passes into both the 

 alpine and hot regions ; and he speaks of having met with it as high as about 6500 feet. 

 Its usual resorts are thicket^, ravines, and dark woods 7. In Guatemala we found it 

 common in the lower part of the belt of forest which surrounds the Volcan de Fuego 

 between 7000 and 10,000 feet, and in the wooded ravines as low as 6000 feet. It 

 here consorted with Sasileuterus cuUcivorus, both species having very similar habits. 

 Nothing is known of its nidification.

This is another of the many discoveries of Herr Deppe in Mexico, whose specimens 

 were allowed to remain buried in the Berlin Museum until after the species was 

 described by Swainson in 1838. Eeference was subsequently made to Deppe's speci- 

 mens by Bonaparte in his ' Conspectus ' i°. 



B. rufifrons enjoys a wide range throughout the temperate regions of Southern 

 Mexico, from the Sierra Madre, near Mazatlan, to the southern confine of the republic. 

 Prof. Sumichrast tells us it frequents, with B. cuUcivorus and B. belli, thickets, ravines, 

 and dark woods, and that, though chiefly found in the temperate region, it also extends 

 its range to the hot region and into the more alpine districts as high as 6500 feet. 



Some doubt seems to exist as to certain specimens, both from Mexico and Guatemala, 

 whether they belong to B. rufifrons or to B. delattrii. Adult fresh-plumaged birds of 

 these two species are easily distinguishable ; but younger birds of the two are not so 

 readily recognized, as in B. rufifrons a yellow tinge pervades the white of the under- 

 surface, and in B. delattrii the yellow of this part is of not nearly so decided a tint as in 

 old birds. It is probably birds of this stage of plumage that have been misnamed. On
