Birds of Southern Cameroon . 
A female (No. 4326), evidently sitting, was caught in the 
nest at about 8 o^clock in the evening. The nest was a 
hanging pocket composed almost entirely of the moss-like 
Usnea with a few cobwebs running through it to give it 
consistency, and a very few fine bits of grass-tops inside 
(just like that already described). Two eggs were in it, 
which measure 16x11 mm. 
[The eggs of this rare species are of a long narrow 
oval form, blunted at the smaller end, and very slightly 
glossy. The ground is dull greenish-blue washed with 
rufous towards the larger end and marked with very small 
dots of light red with smeared edges.—W. R. O.-Gr.]

Nos. 4079, 4081. $ ad.; 4082,4086. ? ad. Irides of all 
dark greyish-brown. Esamesa, R. Ja, Jan. 1910. 
All the examples were shot in the same place, and three 
of them in the same tree, a small Acacia-like tree near the 
village, where they were busily looking for insects in the 
foliage. The finding of this species forms another interesting 
link between the bird fauna of the district of the Ja and 
that of the Central African Lakes. 
Camaroptera griseoviridis. (Plate XII. fig. 13, egg.) 
Sharpe, Ibis, 1908, p. 321; Bates, Ibis, 1909, p. 70. 
My specimens vary greatly in the amount of white on the 
belly. 
A pair of these little birds built a nest in the thickest 
part of the foliage of a guava bush near my house, so that 
I saw and heard them every day. Besides the loud sharp- 
toned notes already described, they had a lower call in a 
sort of whining tone of voice that was very peculiar. 
A young bird (No. 4403), with the plumage not yet grown, 
had the swollen margins of the gape yellowish-white, the 
inside of the mouth orange, and a pair of large black spots 
at the base of the tongue. 
This bird unites the green leaves of a spray, using any 
kind of tree or bush, to form the outside frame for its nest,
