DETAILED LIST OF BIRDS.

The eggs are oval in shape, resembling those of the 
AVagtail, but differing from them in the comparative sparse- 
ness and clearness of the markings. The ground colour is 
generally a pale clear greenish white, and they are thinly 
spotted, speckled, and even streaked with yellowish or 
reddish brown. Where several of the spots occur close 
together a nimbus of the same colour, but paler, more or 
less unites them, and a few somewhat faint brownish purple 
spots and clouds, or an indistinct mottling of this colour, 
are here and there occasionally observable. The eggs vary 
much in size and shape — some are a good deal elongated 
and some conspicuously pyriform. They have very little, if 
any, gloss. In size they vary from 0*9 to 1"03 in length, 
and from 0*68 to 0*75 in breadth. I do not know why orni- 
thologists in India so generally refused to admit Gould's 
species, H. guttatus, which is really very distinct. It is 
perhaps a trifle smaller, with the wing decidedly shorter 
and the tail-feathers narrower, but it is chiefly in plumage 
that it differs from H. maculatus. There is much less 
white on the forehead ; the nape, instead of being, as in 
H. maculatus, white for the breadth of a full inch, the 
feathers narrowly fringed with black, has only a few of the 
feathers broadly white centered. The back, instead of 
being thickly sown with white more or less crescentic 
marks, is thinly sprinkled with small circular dots, the 
largest of which are scarcely one- twelfth of an inch in 
diameter. The black of the breast and lower abdomen 
comes further down than in H. maculatus and is spotless, 
whereas in the latter most of the black feathers of the lower 
breast are narrowly tipped with white. One before me, 
from Darjeling, measures — Length, 10 ; wing, 3'9 ; bill at 
front, 0 75 ; tarsus, I'l. As a whole it is a somewhat more 
sombre-looking bird than the more commonly seen western 
species. \_A. O. H.]

Specimens in nearly full breeding plumage were obtained 
on the 13th of August, at the Chu-Chu Pass, twenty-five 
miles above the plains of Y ark and. It was common on
