Arboricola atrigularis, Blyth. 
The Black-throated Hill-Partridge.

Arboricola atrogularis, Bl., Hume, Cat. no. 824 bis.

For my only record of the nidification of this species I am indebted to Mr. Cripps. He says :- " On the 15th April, 1876, I secured a nest of this bird in Sylhet containing two perfectly fresh eggs. Again, on the 18th May of that year I secured four hard-set eggs from a nest. Both nests were placed at the foot of large trees which stood at the tops of teelahs or hillocks; a few scanty bushes grew about under the trees, but the whole place looked very dark and gloomy. The nests were mere linings of leaves and twigs which had been placed in slight depressions, apparently hollowed out by the birds. The teelahs were about 150 to 200 feet in height."

The eggs are all broad ovals, a good deal pointed towards the small end, and when fresh are apparently pure white, but as incubation proceeds acquire brownish or yellowish-brown stains. The shell is very fine and smooth, showing very few pores, and the fresh egg appears to have a fair amount of gloss.

Six eggs vary from 1.33 to 1.43 in length and from 1.1 to 1.13 in breadth.
