tint and pinkish-grey. All the markings, which are fairly numerous, are 

 more so at the larger end. In shape the egg is a blunt oval, but not at 

 all elliptical as are the eggs of poliocephalus. The texture is fine and 

 close and the surface smooth and glossy, but not silky to the touch, as are 

 the eggs of the cuckoo just mentioned. This egg measures "82" by "GO". 



I took another egg, which, I believe, is an Emerald Cuckoo's, on the 

 10th of May, 1892. I found it in a nest of Orthotomus sutorius (The 

 Indian Tailor-bird), together with three eggs of the owner. When first 

 found the Tailor-bird had laid but two eggs ; the following day it laid 

 another eg-a and I took the whole nest and its contents. The dav when 

 found I shot an Emerald Cuckoo in the patch of grass and scrub in which 

 the Tailor-bird's nest was situated, but at some distance from the nest 

 itself. This egg is a blunt facsimile of that above described as regards 

 shape, texture, &c, but the whole tone of the egg is less bright, and there 

 are no lines on it. With the exception of a few large, smudgy blotches,, 

 the markings are also somewhat smaller. It measures *78" by *63". 



Mr. Hole also sent me two eggs which he considered w r ere of this bird, 

 one of which he took from the nest of S. nigriceps and one from that of 

 S. rufifrons (Hume's Babbler). They measured -79" by -61" and '80" by 

 '61", and were in colouration intermediate between the two described 

 already. They were both taken in July, 1892, at Jellalpur, Cachar, and 

 Emerald Cuckoos were shot haunting the proximity of the nests. 



The eggs are very large for Cuckoos' eggs, in proportion to the size- 

 of the bird, the bulk being as much as it is in the eggs of poliocepJialus 

 and saturatus, birds of, perhaps, between three or four times the cubic 

 contents of the tiny Emerald Cuckoo. 



The range of this bird is much the same as that of the Violet Cuckoo, 

 but it extends further West, having been recorded as far as Kumaon in 

 that direction. It also straggles into Eastern Bengal. 



It used to be wonderfully common during the breeding season at 

 Jellalpur, in Cachar, in the broken ground running along the foot of the 

 hills, and Mr. H. Hole had a marvellous series, all collected at that place. 

 He informed me that he used to find them frequenting Bombax and other 

 lofty trees, hunting for insects and constantly on the move, darting from 

 one perch to another incessantly and twisting about in every position, 

 every now and then giving vent to their musical whistle. They seemed 

 to be sociable birds and consorted much with bulbuls and other birds, and 

 often two or three, or even more, Clirysococcyx might be found together..
