Expedition to the Zambesi Riven . 
81. Camaroptera sundevalli (Sliarpe). 
We obtained our two specimens near Tete. 
C. brevicaudata appears to take its place on the higher 
reaches of the river. 
Adult $. Total length (measured in flesh) 4*68 inches, 
wing 1*95. Iris orange ; upper mandible brown, lower light 
horn-colour ; legs and feet flesh-colour. 
82. Sylviella pallida. (Plate I. fig. 1.) 
Sylviella pallida Alexander, Bull. B. O. C. viii. p. xlviii. 
This species is closely allied to S. minima Grant (see 
below, p. 156), which in my original description of the present 
species (l. s. c.) I erroneously called “S. leucopsis Reichen/” 
Under these circumstances I have thought it advisable to 
figure both species in the accompanying Plate for com¬ 
parison. The British Museum possesses a male and female 
of S. minima from the island of Manda, B. E. A., with 
which we have compared our specimens. From these 
birds the Zambesi specimens differ in the following par¬ 
ticulars :—The upper parts are uniform grey, not washed 
with greenish ; superciliary stripes, chin, throat, cheeks, and 
fore-neck, as well as the middle of the breast and belly, are 
white, tinged with buff, the sides and flanks more distinctly 
washed with the same colour. The bill, which is larger, is 
black, not brown. 
Adult. Culmen 045 inch, wing 2*3, tail 10, tarsus 0*75. 
Iris straw-colour; legs and feet light brown. 
Note .-—We seldom observed this elegant Sylviella. It is 
shy and retiring by nature, keeps much to thick undergrowth 
coating stony ground near the river, and is particularly fond 
of frequenting acacia-growth, from which it seems to gather 
an abundant supply of insect-food. It is interesting to 
watch this bird threading its way through the maze of twigs 
and branches, always examining one bush thoroughly before 
passing on to the next, now hanging Tit-like from some 
pendent twig, the next moment to run in mouse-fashion 
along the branch, looking very like a miniature Nuthatch. It 
is a silent bird, but now and again, when a pair are together, 
the male will keep in touch with the female by uttering a
