some, and black edged with yellow in others. One of the latter was figured in ‘Exotic 
Ornithology’ as the adult male of L. leucothorax. 
The range of this species seems to be quite distinct from that of ZL. leucothorax, and 
extends from the forests of the western side of the mountains of Costa Rica southwards 
as far as Santa Fé in the State of Panama. 
EUCOMETIS.

Eucometis is closely allied to Tachyphonus, and perhaps the only really trustworthy 
difference is in the sexes being coloured alike instead of quite differently, as in Tachy- 
phonus. The commissure of the maxilla is simply curved, or but slightly waved, as in 
Tachyphonus. ‘The wings are rounded, the fourth quill being the longest, the third 
and fifth being nearly equal to it; the tail is long and rounded. The tarsi and feet in 
the more typical EL. cristata are rather slender and feeble, but stouter in E. cassint, 
which does not differ from Tachyphonus in this respect. 
Of the five known species of Hucometis three are found within the limits of our 
fauna; the other two are close allies of EL. eristata, and belong to Guiana, Amazonia, 
and Bolivia. . spodocephala is the only peculiar species in our region, but LE. cassiné 
only just passes beyond it.

This is a north-western form of the Guianan and Amazonian Hucometis penicillata, 
and is found through Western Venezuela and Colombia, and thence passes to the 
isthmus of Darien and into our region as far as the line of the Panama railway. A 
little further westwards, at Santa Fé, its place is taken by E. spodocephala. 
Mr. C. J. Wood, who observed a party of three birds in the valley of the Truando, 
says it frequents bushes and low trees, and has a loud pleasant song °.
