This species has usually passed as C. guadricolor (Vieill.), but, as Count Berlepsch 
has shown 14, it cannot be that bird, the description of which, founded upon a specimen 
said to have come from Trinidad’, better suits Cyanomyia francie of Colombia than the 
present species. 
Count Berlepsch proposed to call this bird Uranomitra ellioti*, but Lichtenstein’s 
title, Trochilus verticalis, a synonym, according to Cabanis and Heine, of C. guadricolor, 
may be used for it, based as it is upon Deppe’s specimens collected in Mexico. 
The range of C. verticalis is chiefly confined to the sierras of North-western Mexico, 
from Mazatlan southwards through the States of Jalisco and Aguas Calientes *. The 
most southern place whence we have received specimens is Zapotlan, which is on the 
south side of the Rio Lerma and Lake Chapala. Floresi’s specimens, of which Gould 
had a number in his collection, were probably all obtained at or near Bolafios. 
M. Boucard tells us that he and M. Sallé found this species at a great elevation on 
the peak of Orizaba during an excursion to that mountain®. No specimens were 
obtained on Popocatepetl by Elwes and Godman in 1888, nor did Mr. Richardson find 
it on the upper parts of Ixtaccihuatl; but Herrera and other writers on Mexican birds 
say that it occurs in the Valley of Mexico, and M. Boucard says he found it breeding 
at Choapam in the month of March 4.

* When in London last summer (1891) Mr. W. Brewster showed us a specimen of a Cyanomyia allied to 
‘ this species from Sonora, It has not yet, so far as we know, been described.
