disgust, as I thought. I then found the body and part of the wings of 

 a non-warningly-coloured butterfly beneath the Sibia's last perch ; but 

 the bird soon ate this body, which it had possibly dropped previously. , 



Afterwards I saw the Sibia eat another non-warningly-coloured 

 butterfly. The P. demoleus, panope and aristolochise, the D. genutia and 

 limniace, and the Euplcea which had been there all day, were still left 

 when the birds went to roost. 



May 3rd. In the morning all the butterflies left over-night remain- 

 ed for some time. Later on the Papilio panope had been devoured, and 

 the P. demoleus had disappeared. 



I then released the P. aristolochise, which now seemed slightly in- 

 jured, but flew away. Later still the Danais genutia and D. limniace 

 had apparently been eaten, as I only found wings about ; and subsequent- 

 ly to this the Euplcea had disappeared, a small bit of wing only being 

 left. 



In the evening, there being plenty of maggots and other food in 

 the cage, I put in a Neptis, which was seized by a Liothrix ; this bird 

 was pursued by the Sibia, which took the butterfly, but soon rejected 

 it, when it was swallowed whole by the Yellow-vented Bulbul. 



I then pnt in one specimen each of D. chrysippus, D. genutia, 

 and J), limniace, Euplcea, P. demoleus, and a much worn P. panope, with 

 a male Eypolimnas. This last was soon seized by the Sibia, which ate 

 it after tearing off the wings, not without trouble, partly on account of 

 it toughness, and partly by reason of the other birds ; one Liothrix tried 

 to snatch the prey, even hanging from it for a moment. Another 

 Liothrix then took the P. demoleus, but dropped it and wiped its beak. 

 The Euplcea was then taken by that Liothrix which had tried to rob the 

 Sibia of its prey. The Mesia, however, snatched it from this bird, but 

 let it go, and it flew freely about in spite of this treatment. 



The P. panope soon appeared to be injured, perhaps by Liothrix, 

 but I did not see any bird touch it; it was much rubbed, and hardly 

 recognizable. 



May 4<th. This morning all the butterflies (Euplcea, Danais chrysippus, 

 genutia, and limniace, Papilio panope and demoleus) left over-night were 

 uneaten. The D. genutia had got behind a vessel, so I took it out, and 

 Roon after found it minus some of its wings, but uneaten ; while of the 

 P. panope only the two fore-wings and the thorax remained. The 

 insects had obviously been tried by the birds. The D. chrysippus had 

 also been mauled, and a little later I found it minus its head, by which 

 time the abdomen of the D. genutia had also disappeared ; I think I 

 had noticed previously that its head was gone. 



Some time later I saw the Euploea, D. limniace, and P. demoleus
