Malacias melanoleucus (_Bl.), Hume, cat._ no. 429 quart.
Mr. W. Davison was fortunate enough to secure a nest of this Sibia on
Muleyit mountain in Tenasserim. He says:--"I secured a nest of this
species on the 21st of February, containing two spotless pale blue
eggs slightly incubated. The nest, a deep compactly woven cup, was
placed about 40 feet from the ground, in the fork of one of the
smaller branches of a high tree growing on the edge of a deep ravine.
"The egg-cavity of the nest is lined with fern-roots, fibres and fine
grass-stems; outside this is a thick coating of dried bamboo-leaves
and coarse grass, and outside this again is a thick irregular coating
of green moss, dried leaves, and coarse fibres and fern-roots.
"Externally the nest measures about 5 inches in height, and nearly the
same in external diameter at the top.
"The egg-cavity measures 1·7 deep by 2·7 across.
"The eggs, a pale spotless blue, measure 0·95 and 0·98 in length by
0·66 and 0·68 in breadth."
