Mr. G. L. Bates on the 
and was deep, and built high on the more exposed or open 
side. 
The extremely small nestlings had the mouths inside and 
the tongues bright orange, unmarked, and the margin of 
the gape yellowish white. 
Elminia longicauda. (Plate IX. fig. 20, egg.) 
Sharpe, Ibis, 1904, p. 631; 1907, p. 456 ; Bates, 1905, 
p. 470. 
The habits of this bird were deseribed in * The Ibis , (1905, 
p, 96), with its nest (1905, p. 457) and its eggs (1909, p. 32). 
One of those eggs, No. 41, is figured here. Other nests and 
eggs have been found, but the eggs were broken. A nest, 
brought in with the male bird, No. 3023, contained a 
single very young nestling. The inference from the fact 
that the first breeding birds and nests were found in June, 
namely, that this species has a distinct breeding-season, has 
proved partially correct, as the eggs and young found since 
have been in the months of March, April, and August, that 
is, all within a single half-year. 
As this is a bird of the cleared land, averse to the forest, 
it is naturally most abundant about the Ja and Bitye ; it 
was rare at Efulen, and not seen at all at Assobam, where 
the extent of the cleared land is small.
