CHLOROPHONIA. 253 
The general colour of all the species of Chlorophonia isa bright grass-green, and this 
is one of the minor characteristics of the genus. 
Eight or nine species of Chlorophonia have been recognized, of which three (including 
C. cyanodorsalis, of which we know so little) occur within our country, all of them being 
peculiar to it. They are the largest members of the genus; and have been separated 
from the rest by Dr. Cabanis under the name of Acrocompsa. 
Of the five or six South-American species, C. viridis enjoys the widest range, 
being found in Brazil and Bolivia as well as Ecuador; and if C. longipennis prove 
inseparable, it extends also into Colombia. In the latter country C. pretrit is found. 
C. flavirostris, a bird as yet known by a single specimen, is from Ecuador. The almost 
equally rare C. torrejoni, Tacz., is from North-eastern Peru. Lastly, C. frontalis is from 
Venezuela, the Sierra Nevada of Santa Marta, and from Guiana. It will thus be seen 
that, with the exception of C. viridis, all the South-American members of the genus 
have a very restricted range. 
The same may be said of the species of Central America. C. occipitalis is restricted 
to Southern Mexico and Guatemala, and C. callophrys to Costa Rica and the adjoining 
parts of Panama. C. cyanodorsalis is attributed to Guatemala; but of this species we 
know as yet hardly anything.

This pretty species does not seem to have been known to the earlier collectors in 
Mexico (Bullock, Deppe, and others), and it was not until 1847 that a female specimen 
placed in the Brussels Museum was described by DuBus, and figured in his ‘ Esquisses 
Ornithologiques’+. Since then the bird has been found from time to time in Southern 
Mexico, but chiefly in the State of Vera Cruz, where Sumichrast tells us it is a bird of the 
hot region, shifting its quarters in search of food to places elevated as high as 4000 feet 
above the sea. M. Boucard never seems to have met with it in the State of Oaxaca; but
