GRAUCALUS C&SIUS. 399 
from which it is distinguished at a glance by its bright yellow shoulder- 
spot. We have received a few specimens procured by Mr. Atmore 
in the neighbourhood of George. It likewise occurs in Natal, where 
-Mr.Ayres has found it inhabiting the coast range. He states that the 
__ females are more numerous than the males, and are generally found 
in small companies when moving about; in appearance and shape, 
and also in fight, they much resemble the hen-bird of the Emerald 
Cuckoo (Cuculus smaragdineus). It has also been procured in 
Benguela by Senor Anchieta. 
Adult male.—Glossy black, with a bright shoulder-spot of lemon 
yellow, occupying the lesser coverts and the outermost of the median 
series. Total length, 8°5 inches ; culmen, 0°7; wing, 4°15; tail, 4-6; 
tarsus, 0°8. The female is of a greenish grey colour, banded with 
black above ; white below, also banded with black, and is, in fact, not 
to be distinguished from the female of 0. nigra. The red-shouldered 
Campophaga pheenicea does not occur in South Africa,

Campophaga Levaillanti, Layard, B. 8. Afr. p. 153. 
This species has a limited range, and is strictly South African 
in its habitat. We found them in small flocks frequenting 
the tops of lofty trees in the Knysna forests, searching after 
insects. Le Vaillant also seems to have procured them in the 
Outeniqua, and on the borders of the Sunday and Zwartkop Rivers. 
Mr. Rickard notes them both from Port Elizabeth and Hast London, 
and we have seen them from the neighbourhood of Grahamstown. 
Lieut. Trevelyan informs us that near Kinewilliamstown it is rather 
__- scarce, and in Natal it inhabits the dense bush on the coast range. 
Captain Shelley writes :—“ Not very uncommon in the thick bush 
near Durban. A boy who was with me shot at one of these birds 
with a catapult, when it dropped a Mantis it was feeding on, but was 
so intent upon its prey, that it came quite close to pick it up again, 
and was dispatched by another shot.” 
Adult male.—General colour above and below dark bluish grey, 
somewhat lighter on the forehead and sides of the crown ; wings like 
the back, the primaries blackish, narrowly edged with grey ; tail- 
feathers blackish, slightly washed with grey, the outermost paler 
towards the tip; round the eye a ring of whitish or grey; lores and 
feathers in front of the eye slaty black, the shade of this colour
