7 2 Mr. G. L. Bates— Field-Notes on the 
My specimens were obtained in snares baited with termites, 
along with birds of the genera Alethe, Turdinus , Bleda, 
Neocossyphus , &c. Young birds have spots on the wing- 
coverts, as have those of Alethe . 
Sylviella batesi. 
Sharpe, Ibis, 1908, p. 319. 
Both my specimens of this species were caught or shot 
in their nests. The male (which had the testes very large) 
seemed to be sitting. The two nests were alike, and 
resembled those of some other small Warblers in being 
pocket-shaped; but in materials and structure they were 
peculiar. These small pockets were made of short leaf- 
petioles, not woven together, but held together loosely by 
gossamer-threads (of spider’s or caterpillar’s web) running all 
among them, and extending up over the twig so as to form 
the attachment, which is not at one point of the twig, but 
extends along for several inches. Thus the whole structure 
is as flexible as a knitted bag. All over the outside are 
many particles of trash hanging to the gossamer-threads, 
that tremble at the slightest breath. Inside the bag are 
a few fibres for nest-lining. A single egg was found in each 
nest; the two were just alike, except in size, one measuring 
19 X 12 mm., and the other 16*5 x 11 mm. 
[Two eggs are of a long pointed oval form and devoid 
of gloss. The ground-colour is yellowish-clay, thickly 
mottled all over with umber-brown and grey, the markings 
being more or less clouded and indistinct.—O.-G.] 
2124. Sylviella virens.

Two of my female specimens were caught in their nests, 
which were suspended in the bushes or grass. The nest 
is a nicely constructed little pocket like that of a Sunbird. 
In one nest were three or four tiny eggs, which got broken 
when the bird was caught; it could be seen, however, that 
they were speckled on a white ground.
