till finer materials than the
outside. The cavity is nearly 21/2 inches deep, measuring from the lower
edge of the entrance, and is about 2 inches in diameter.

During this present year (1874) Mr. Parker obtained several more
nests of this species, all built in the low jungle that fringes the
mud-banks of the congeries of channels and creeks that are known in
Calcutta by the name of the "Salt Lake."

This jungle consists chiefly of the blue-flowered holly-leaved
_Acanthus ilicifolia_ and of the trailing semi-creeper-like _Derris
scandens_. It is in amongst the drooping twigs of the latter that the
nest is invariably made.

The nests vary a good deal in shape; some are regular cylinders
rounded off at both ends, with the aperture on one side above the
centre--a small oval entrance neatly worked. Such a nest is about 4.5
inches in length externally from top to bottom, and 2.75 in diameter;
the aperture 1.3 in height, and barely 1.0 in width.

Others are still more egg-shaped, with a similar aperture near the
top, and others are more purse-like. The material used appears to be
always much the same--fine grass-stems intermingled with blades of
grass, and here and there dry leaves of some rush, a little seed-down,
scraps of herbaceous plants, and the like; the interior, always of the
finest grass-stems, neatly arranged and curved to the shape of the
cavity. The nests are firmly attached to the drooping twigs, to and
between which they are suspended, sometimes by line vegetable fibre,
but more commonly by cobwebs and silk from cocoons, a good deal of
both of which are generally to be seen wound about the surface of the
nest near the points of suspension or attachment.

Four appears to be the full number of the eggs. Mr. Doig, writing from
Sind, says:--"This bird is tolerably common all along the Narra, but
as it keeps in very thick jungle it is not often seen unless looked
for. I took my first nest on the 12th, and my second on the 17th of
May. This evidently is the second brood, as I noticed on the same day
a lot of young birds which must have been fully six weeks old. One
nest was lined with horsehair and fine grasses. Four was the normal
number of eggs."

Mr. Gates writes:--"The Yellow-bellied Wren-Warbler is very abundant
throughout Lower Pegu in suitable localities. In the plains between
the Sittang and Pegu rivers they are constant residents, breeding
freely from May to August and September. In Rangoon also, all
