CAMAROPTERA OLIVACEA. 293 
276. ACROCEPHALUS SCH@NOBANUS. European Sedge- Warbler. 
The Common Sedge Warbler of Europe has only as yet been met 
with in Damara Land as far as regards the limits of the present 
work. Mr. Andersson thus records the circumstances of its cap- 
ture :—“I obtained two specimens on December 22nd, 1866, at 
Otjimbinque in the bed of the river, amongst some ‘ cotton-plants,’ 
on which, and on the ground, they were hopping about in search of 
insects: they were new to me.” We have seen two specimens from 
the Congo district, obtained by M. Louis Petit, so that the line of 
migration probably lies along the west coast. The following 
description is from one of Mr. Andersson’s specimens. 
General colour above fulvous brown, streaked with dusky brown 
on the back, and with black on the head: rump tawny buff, the 
upper tail-coverts brown with dusky centres: wings dark brown, 
all the feathers edged with fulvous brown, the primaries with some- 
what ashy brown: tail-feathers dark brown with lighter fulvous 
brown edgings, the outer feathers lighter: lores and a distinct eye- 
brow yellowish buff: in front of the eye a dusky spot: ear-coverts 
brown washed with fulvous: cheeks and under surface of body 
yellowish buff inclining to tawny on the flanks and thighs, and to 
brown on the sides of the upper breast: throat and centre of 
abdomen buffy white: under wing-coverts ashy whitish washed with 
yellow on the edge of the wing: ‘‘upper mandible dark horn-colour, 
the lower brownish, but both yellowish at the edge: gape bright 
orange yellow : legs and toes livid brown: iris dark brown” (Anders- 
son). Total length, 4°5 inches; culmen, 0-55; wing, 2°53; tail, - 
1°75 ; tarsus, 0°85.

Calamodyta olivacea, Layard, B. S. Afr., p. 98. 
We have only seen this species ourselves from the neighbourhood 
of Graham’s Town, but it has also been found in Natal by Mr. T. 
Ayres, and the latter gentleman gives the following account of it in 
that colony :—“ The Caffres call this bird ‘ Imboos Ischlaty” (sig- 
nifying “bush goat”), from its curious notes when it sees an object 
of suspicion or dislike, which much resemble the bleating of a kid 
at a distance, although the tiny bird may be within a few feet of the
