AMAZILIA. 293 
In many respects Amazilia resembles Cyanomyia and Agyrtria, the main points of 
structure being similar, the culmen being feathered to the base, but so as to leave the 
nasal covers distinctly exposed on their anterior portion. In Amazilia the throat is 
never wholly white, and none of its members have any glittering blue colours, or any 
glittering colours on the top of the head. 
We are more or less acquainted with twenty-nine species of Amazilia, but there are 
some others which we have not met with ; the former are spread over the Andes as far 
south as Peru, and over the northern portion of South America, none, so far as we 
know, occurring in the valley of the Amazons nor in Brazil. In Central America and 
Mexico we recognize thirteen species, two of which range as far north as the mouth of 
the Rio Grande. On the western side of Mexico, Mazatlan is the most northern point 
reached, Only one species also occurs in South America. Generally speaking, all 
species of Amazilia are birds of comparatively low-lying lands, but they ascend the 
mountains at certain seasons to an elevation of at least 4000 feet.
