EUPHERUSA. 271 
country—Z£. poliocerca to South-western Mexico, E. eximia to Guatemala and Central 
Nicaragua, and £. egregia to Costa Rica and the adjoining part of the State of 
Panama. 
Asin Microchera and Callipharus the inter-ramal space is more or less feathered ; 
the bill is slender, the tomia of the maxilla turned inwards towards the tip; the sexes 
dissimilar ; the tail rounded. It differs from those genera in having a decurved bill, 
which is comparatively long, the white at the base of the lateral rectrices does not 
extend to the whole of the outer webs, and the size of the birds is considerably larger.

Hab. Mexico, Chinautla (Loucard), Chimalapa and Sierra de Santo Domingo in 
Tehuantepec (W. &. Richardson"); Guatemata, Coban (Delattre!, 0. 8S. & 
f. D. G.*), Kamkhal, Choctum and track between Cahabon and San Luis (0. 8. 
& F. D. G5); Nicaragua, Matagalpa (W. B. Richardson’). 
The French traveller Delattre discovered this species at Coban in Guatemala, and 
subsequently described it in 18431. It was at Coban that Salvin found it in 1859 to 
be one of the commonest Humming-Birds during the month of November, frequenting 
the flowering-plants, principally Salviw, which abound at that season in the vicinity of 
the town. . eximia is also found in the forest-region lying to the northward of Coban 
as low as about 1200 or 1500 feet above sea-level. We never met with it in any other 
part of Guatemala; but its range passes a little beyond the limits of that country both 
to the northward and southward, as M. Boucard says that it occurs at Chinautla in 
Puebla in the month of August, and Mr. Richardson found it on the Isthmus of Tehu- 
antepec, both at Chimalapa and in the Sierra de Santo Domingo, in March and April, 
and also near Matagalpa in the highlands of Central Nicaragua in July. The eastern 
slopes of the mountains of Central America between these limits probably mark the 
limits of the range of this species. 
Though observed in great numbers at Coban we never found a nest, and noticed 
nothing peculiar in its habits.
