Mr. D. G. Elliot on the Trochilidse. 
washed with rufous ; feathers in front of the eye fulvescent; 
cheeks and ear-coverts dark brown, narrowly streaked with 
whitish; throat white, the chin unspotted, but the rest of the 
throat broadly streaked with dark brown, these streaks be¬ 
coming plainer on the breast, which, like the sides of the 
neck, is more ashy grey than the rest of the back; flanks 
brown, as also the thighs and under tail-coverts; centre of 
abdomen white; under wing-coverts ashy brown, mottled with 
dark brown markings. Total length 5*8 inches, culmen *55, 
wing 2'45, tail 2’6, tarsus *85. 
A second specimen is more dingy underneath, and is not 
so clearly marked as the one described. It seems to me to 
differ from all the other African Bradypteri, of which the 
Museum has a large series, by its black bill and distinctly 
striped throat and breast. 
VII.— Notes on the Trochilidse. The Genus Lampropygia. 
By D. G. Elliot, E.B.S.E., E.L.S., &c. 
The genus Lampropygia contains only a few species; but they 
are large handsome birds, possessing a considerable amount 
of metallic colouring. They are closely allied on the one 
hand to the members of the genus Bourcieria, and on the 
other to those composing the genus Agl&actis ; indeed I 
am not altogether satisfied of the necessity of separating them 
from the first-named genus, and think perhaps it may be 
better, in some future arrangement of the family, to retain the 
species treated of in this paper in the genus Bourcieria. The 
birds usually restricted to the genus Lampropygia are met 
with from Venezuela down the western coast of South Ame¬ 
rica to Bolivia, no species having been found inhabiting 
Eastern South America or any portion of Central America. 
Venezuela contains L. cceligena, described by Lesson, and 
erroneously attributed by him to Mexico ; Columbia has three 
species, L. columbiana (characterized in this paper), L. pru- 
nelli, and L. wilsoni, the last being also an inhabitant of 
Ecuador; while Bolivia, as yet, has only given us L. boliviana,
