First described from Southern Mexico by Mr. Sclater in 1856, Certhiola mexicana 
has gradually been traced through Guatemala and the rest of Central America, and 
along the slopes of the Andes as far south as Bolivia. It is true that various attempts 
have been made to divide the birds found in this area into several races: but, with a 
large series before us, we feel convinced that no separation can be maintained. Its 
range on the continent of South America is somewhat peculiar, in that it extends in an 
almost straight line, not diverging at all to the eastwards, for in Venezuela a distinct 
species (C. luteola) quite takes its place. 
In Guatemala C. mexicana has none of the habits which render the Antillean species 
so familiar; for we never observed it frequenting the houses as the allied species are 
wont todo. In Guatemala, indeed, it is by no means a widely distributed bird, being 
restricted in its range, so far as we know, to the tropical forests of northern Vera Paz, 
atan elevation of about 1200 feet above the’sea. Here, however, it is common enough, 
judging by the number of specimens obtained for us by our native collectors. 
We never obtained its nest or eggs; but Salmon, who met with both at Remedios 
and Medellin in the Colombian State of Antioquia, describes the former as made of 
fine dry grasses, and oval in shape, with a side entrance; it is usually placed at the 
extremity of a bough, but not suspended from it. The eggs are dirty white, thickly 
spotted with red-brown, especially in a zone under the larger end; they measure 
65 by “5°
