Genera of Humming Birds. 165 



Male. — Differs only from C. violiceps by the colour of 

 forehead, which is dark green, metallic in some lights. 



It was discovered by my traveller, Eugene Rebouch. 



The type is now in the New York Natural History Museum. 



238. Cv.\NOMViA GUERRERENSIS, Salv. and Godm., Biol. cent. 



ameri., 1892. 

 Guerrero Green Crown. 

 La Leucolie de Guerrero. 

 Habitat. — Guerrero, Mexico. 



This new species is very nearly allied to C. viridifrons, 

 so much so, in fact, that I am of opinion that both belongs to 

 the same species ; I have one specimen, from Mazatlan, col- 

 lected by Mr. Forrer, which I can only refer to that species. 

 The type specimen of C. viridifrons, was collected at Putla, 

 which is close to the state of Guerrero. It is therefore 

 probable that it is found all over the Mexican west coast, 

 from Tehuantepec to Mazatlan, and even more north. 



The specimens from which Mon. Salwin and Godm described 

 the species, were collected by Mrs. Smith.
