ERyTHROCERCUS THOMSON], sp. n. (Plate XVI. fig. 2.) 
Upper parts olive-yellow; rump and upper tail-coverts rufous 
washed with yellow; tail rufous, the feathers slightly washed with 
yellow on their edges and crossed by a broad black subterminal 
band; in one specimen the outer feather alone is without any black 
baud, and the next feather is only banded on the outer web, with a 
black spot on the inner one; in the second specimen the four outer 
feathers on each side are without any black at all; rictal bristles 
black, forehead rather narrowly margined with brownish buff; lores 
and in front of the eye white (but the state of the skins prevents 
me from seeing the limits of this colour on the sides of the head) ; 
wings dark brown, all the feathers broadly edged with olive-shaded 
yellow excepting towards the ends of the primaries; entire under 
surface bright yellow ; under wing-coverts yellow, basal portion of the 
inner webs of the quills rather narrowly edged with rufous buff. 
Bill—upper mandible brown, lower one flesh-colour. Legs and 
claws pale brown. Total length 4:5 and 4:1 inches; culmen 0°25; 
wing 1°9 and 1°8; tail 21; tarsus 065. 
On referring to Mr. Sharpe’s Cat. B. Brit. Mus. iv. p. 208, pl. 9, 
we at once recognize Erythrocercus livingstonii as the nearest ally 
of this new species; and I shall propose the following addition to his 
key of this genus :— 
a. Tail uniform, without a bar: to include C. macalli and C. living- 
stonit. 
6. Tail with a broad black subterminal bar: C. thomsoni. 
The present species further differs from C. Livingstonii in the crown 
and sides of the head being the same colour as the back, the forehead 
alone being margined with brownish buff, and the chin scarcely shows 
a trace of white. 
MERopPs DRESSERI, sp. n. (Plate XVI. fig. 1.) 
Crown and nape fawn colour, the tips of the feathers slightly - 
washed with greenish yellow ; remainder of the upper parts green; 
the basal portion of the inner margins of the quills pale fawn colour ; 
the primaries have the remainder of their inner margins and their 
ends dusky black; the secondaries are rather broadly tipped with 
black, with the exception of the inner feather, which, like the longer 
scapulars and upper tail-coverts, is washed with blue towards its 
end; two centre tail-feathers green, gradually shading into black on 
their long narrow ends, which are slightly widened at the tips; 
remainder of the tail square, the feathers with broad black end, 
narrowly tipped with white on the outer ones, and rather more broadly 
so with blue as they approach the centre pair; on the sides of the
