Zoster ops pallida 8f Z. lateralis, Layard, B. S. Afr., p. 117.
This species is more generally known under Sundevall’s name of
lateralis, which was changed by Dr. Hartlaub (J. f. 0. 1865, p. 9) to
Z. sundevalli, as there existed already a Z. lateralis. We believe at
the same time that it is without doubt the Z. pallida of Swainson
which was described from a specimen of Dr. Burchell’s. We have
received the species from Mr. Ortlepp at Colesberg, and Mr. Thomas
Ayres has met with it in the Transvaal, where, he says, “ it is
occasionally seen in small companies, actively hopping and climbing
about the hedges and trees during the winter months.” The
present species may be distinguished from Z. capensis by its yellow
forehead, bright yellow throat, and by its isabelline-brown flanks.
Adult male.—General colour above olive-green, decidedly clearer
and more' yellow on the upper tail-coverts; forehead and lores
bright yellow; in front of the eye a black spot, extending in a line
under the eye; round the eye a ring of silvery white feathers; sides
of face and ear-coverts olive-green; cheeks and entire throat bright
yellow, ending abruptly on the fore-neck: centre of the body
whitish, slightly washed with tawny: sides of upper breast greyish
brown, the flanks pale isabelline brown: under tail-coverts bright
yellow: under wing-coverts dull white washed with yellow on the
edge of the wing: upper wing-coverts green like the back : quills
dark brown, the primaries externally margined with yellowish green,
the secondaries with olive-green: tail-feathers brown with olive-
green edgings. Total length, 4‘7 inches; culmen, 0 5 ; wing,
2'35; tail, 1‘9; tarsus, 0'7.
310. Z ost erops sen eg a l en s is . Yellow White-eye.
The following account of this species in South Western Africa is
taken from Mr. Andersson’s work on the Birds of Damara Land:—
“ I never met with this exquisite little bird in either Great Namaqua
or Damara Land; and it was only as I approached the Okavango
that I became aware of its existence. In the thornless forests
bordering upon this stream it is not uncommon, but it migrates
northwards during the dry season. It is found in small flocks, and
diligently explores in search of insects the branches of the smaller
trees, and especially the buds and flowers, suspending itself in a
variety of positions while it is thus employed.” Senor Anchieta has
obtained it at Biballa in Mossamedes.
This species cannot be mistaken for any of the other South
African White-eyes as its general yellow colour renders it very
distinct.
Adult.—General colour bright olive-yellow, rather more intense on
the rump and upper tail-coverts : wings pale brown, all the feathers
edged with yellow, a little greener in tint than the back, the innermost
secondaries washed with yellow all over: tail light ashy brown
with narrow margins of olive-yellow : forehead and lores brighter
yellow than the crown of the head: in front of the eye a dusky
blackish spot: round the eye a ring of white feathers : sides of face
bright yellow, slightly more green on the ear-coverts: entire under
surface of body bright yellow, slightly washed with greenish on the
sides of the upper breast: under wing-coverts and axillaries whitish
washed with bright yellow, the edge of the wing bright yellow:
under surface of quills greyish brown, with an edging of ashy-buff
along the inner web. Total length, 3’6 inches; culmen, 0'4; wing,
2’1 ; tail, 1’35 ; tarsus, 0'6.

Described originally by Sundevall from a specimen obtained by
Prof. Wahlberg in “ Upper Caffraria.” Mr. Thomas Ayres has
procured it in Natal, where he says they are plentiful in the spring
of the year. Captain Shelley has also received a number of specimens
from Mr. T. L. Ayres at Pinetown, and Mr. P. A. Barratt
shot specimens at Macamac. Mr. Thomas Ayres in his account of
birds from the Lydenburg district also writes:—“ This species is
