entire underparts being of a nearly uniform yellow, its black bill, and other minor 
characters. 
It is in all probability a resident species in Mexico, where alone it has been procured 
up to the present time.

Hab. Mexico (de Saussure 4), mountains of Orizaba (Swmichrast 2). 
But little is known of this pretty species, which was first obtained by M. de Saussure 
during his travels in Eastern Mexico, and described by Mr. Sclater in 1858". Since 
then the only specimen that we have met with is a female in our own collection, which 
was picked out of a lot of Mexican skins, the precise locality where they were obtained 
not being stated. Prof. Sumichrast refers to this species a bird found in the alpine 
region of the mountains of Orizaba 2, and speaks of its being represented in the collec- 
tion of the late Sefior Mateo Botteri. 
The authors of the ‘ History of North-American Birds’ * throw great doubts on the 
validity of this species and of G. semiflava of Ecuador, believing them to be referable 
to G. trichas. A moment’s comparison of specimens of these three species is enough to 
show that they are all three perfectly distinct from one another, as Salvin has already 
pointed out®. The absence in the male of the white band across the head at once 
separates G. speciosa and G. semiflava from G. trichas; and the black bill and ochre- 
yellow tint of the under plumage of G. speciosa separate that species from G. semiflava, 
which has the base of the mandible whitish and the under surface clear yellow. 
Like G. melanops, G. speciosa would appear to be a sedentary species in Southern 
Mexico.
