olive-green spots and speckles, and there are numerous other abnormal
varieties which I have not observed amongst the Ravens.

On the whole the eggs do _not_ vary much in size; out of one hundred
and ninety-seven, one hundred and ninety-five varied between 1·28 and
1·65 in length, and 0·98 and 1·15 in breadth. One egg measures only
1·2 in length, and one is only 0·96 in breadth; but the average of the
whole is 1·44 by 1·06.


8. Corvus insolens, Hume. _The Burmese House-Crow_.

Corvus insolens; _Hume; Hume, Cat._ no. 663 bis.

The Burmese House-Crow breeds pretty well over the whole of Burma.

Mr. Oates, writing from Pegu, says:--"Nesting operations are
commenced about the 20th March. The nest and eggs require no
separate description, for both appear to be similar to those of _C.
splendens_."

When large series of the eggs of both these species are compared,
those of the Burmese Crow strike one as _averaging_ somewhat brighter
coloured, otherwise they are precisely alike and need no separate
description.
