pointed at the other. The shell is hard, compact, and everywhere 

 closely pitted with minute pores, but it is very smooth notwith- 

 standing, and has a very fair amount of gloss. The ground is a 

 pale drab or clay-colour, but the whole of the large end has "a 

 faint reddish- brown tinge, as has also the extreme poiut of the 

 smaller end. 



The egg measures 1'77 in length by 1'2 in breadth.

For roy only record of the nidification of this species I am in- 

 debted 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 lea\es 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 incu- 

 bation 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 l-;33 to 1-43 in length and from I'l to 1-13 in 

 breadth.

Little is known about the nidification of this species. To Mr. 

 Mandelli I am indebted, however, for one of its eggs. He found 

 a nest on the 4th July, at Pattabong, below Darjeeling, at an eleva- 

 tion of about 4000 feet, containing four fresh eggs. The nest is 

 described as having been a heap of dry leaves placed on the ground. 

 The egg is a broad oval in shape, pointed towards the small end ; 

 in colour a sullied white \^ ith a few very minute grey specks dotted 

 about on it ; the shell rather fine and smooth, but with very little 

 perceptible gloss. It measures 1"5 by 1-2.
