Birds of Southern Cameroon. 619 



A female (No. 432G), 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 16 x 11 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.-G.]

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 po. ir. 



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, lasing any 

 kind of tree or bush, to form the outside frame for its nest.
