small end (_vide_ the representation of the eggs
of _Ruticilla tithys_ in Hewitson's work).

In length they vary from 0.63 to 0.68, and in breadth from 0.48 to
0.53; but the average of fifteen eggs measured is 0.65 by 0.5.

Willow-Warbler_.

Reguloides viridipennis (_Blyth), apud Hume, cat._ no. 507[A].

[Footnote A: Mr. Hume is of opinion that this bird is the true _P.
viridipennis_ of Blyth. I have elsewhere stated my reasons for
disagreeing with him.--ED.]

It was on the 2nd of February, just at the foot of the final cone of
Mooleyit, at an elevation of over 6000 feet, that Mr. Davison came
upon the nest of this species. He says:--

"In a deep ravine close below the summit of Mooleyit I found a nest of
this Willow-Warbler. It was placed in a mass of creepers growing over
the face of a rock about 7 feet from the ground. It was only partially
screened, and I easily detected it on the bird leaving it. I was very
much astonished at finding a nest of a Willow-Warbler in Burmah, so
I determined to make positively certain of the owner. I marked the
place, and after a short time returned very quietly. I got within a
couple of feet of the nest; the bird sat still, and I watched her for
some time; the markings on the top of the head were very conspicuous.
On my attempting to go closer the bird flew off, and settled on a
small branch a few feet off. I moved back a short distance and shot
her, using a very small charge.

"The nest was a globular structure, with the roof slightly projecting
over the entrance. It was composed externally chiefly of moss,
intermingled with dried leaves and fibres; the egg-cavity was warmly
and thickly lined with a felt of pappus.

"The external diameter of the nest was about 4 inches; the egg-cavity
1 inch at the entrance, and 2 inches deep.

"The nest contained three small pure white eggs."

The three eggs here mentioned measured 0.59 and 0.6 in length, by 0.49
in breadth.

Flycatcher-Warbler_.

Abrornis albosuperciliaris, _Blyth, Jerd. B. Ind._ ii, p. 202; _Hume,
Rough Draft N. & E._ no. 573.

Throughout the Himalayas south of the first snowy ranges, and in all
wooded valleys in rear of these, from Darjeeling to Murree, this
Warbler appears to be a permanent resident.

I have received its nests and eggs from several sources, and have
taken them in
