to Tonala, but when at Retalhuleu in 1862 Salvin saw in the collection of Dr. Bernoulli 
a skin of a Cyanomyia which, from a note made at the time, was most probably of this 
species. 
4. Cyanomyia guerrerensis, sp. n. 
C. viridifronti similis, sed capite summo et fronte saturate obscure cyaneis nec viridibus, dorso postico paulo 
grisescentiore, forsan distinguenda. 
Hab. Mexico, Rincon, Acaguizotla and Tierra Colorada in Guerrero (Mrs. H. H. 
Smith). 
Five specimens of this Cyanomyia in Mrs. Smith’s collection, made in the Sierra 
Madre del Sur in the State of Guerrero, all agree in having the forehead and crown 
dark indigo-blue, instead of dark green as in the type of C. viridifrons; the back, too, 
seems a little greyer, and the tail perhaps deeper bronze. 
As this bird appears to have a distinct range from C. viridifrons, we now describe 
it, but the characters are undoubtedly slight and we do so with some diffidence. 
The position of both these birds is to some extent made more doubtful from the 
fact of C. violiceps being found in the districts occupied by each of them. The green 
colour of the flanks under the wings in both C. viridifrons and the present bird con- 
trasted with the dusky flanks of both C. verticalis and C. violiceps, as well as the total 
absence of glittering feathers on the crown in all stages of the two first-mentioned 
birds, is fair evidence of their distinctness. 
We may further remark that one of the Guerrero birds is quite young in first 
complete plumage, the feathers of the head are in moult, and the new ones are of the 
dark indigo-blue of the other more adult specimens. 
B. Maxilla nigra; hypochondrie viride lavate.

We have not met with any bird agreeing with the above description. Mr. Elliot, 
when describing the species, stated that the type was said to come from Honduras.
