Icterus gularis is extensively distributed through Southern Mexico, where it has been 
obtained on both sides of the mountain-range, and according to Swainson on the table- 
land, but this we think is probably an error; it is omitted from Sumichrast’s list of the 
birds of the State of Vera Cruz, but he met with it abundantly on the Pacific side of 
the Isthmus of Tehuantepec. Mr. Gaumer has sent us a specimen from Yucatan and 
many examples from the island of Cozumel. In Guatemala its distribution is rather 
local, for skins of it do not occur in collections made by the natives of Coban ; but about 
the plains of Salama and Zacapa, where the vegetation is much less dense, it is far from 
uncommon; it also spreads throughout the coast-region of Guatemala bordering the 
Pacific up to an elevation of about 3000 feet. It is thus a bird of the lowlands, and 
we have no record of it from the higher portion of the mountain-ranges. Mr. R. Owen 
secured an egg of this species together with the hen bird at San Gerénimo in 1860; it 
is pale grey, blotched and streaked with very dark brown. 
There is a good deal of variation in the intensity of the orange colour of this bird, 
as well as in the general dimensions, but we do not think any satisfactory division is 
possible.
