oval, occasionally somewhat pyriform in shape, and rarely very long aud narrow like
those of our Indian Swift. They are perfectly spotless, and so far as shape aud size go
the egg of II. daurica figured by Bree sufhcieutly correctly represents au average specimen.
Many eggs, however, are longer and narrower than that figure, and while all are, as in
the figure, somewhat pointed towards the end, some are conspicuously so.
“ The eggs vary from 0 75 to 0-83 inch in length, aud from 0*52 to 0-6 inch in
breadth; but they average about 0-78 by 0*55 inch.”
The descriptions are taken from specimens in the British Museum. The figure is
drawn from a bird in Mr. Wyatt’s collectiou, procured by him ou Mount Abu, and a
view is given of one of the corners of the Eort at Agra.
