let the bird out for a time, leaving the Euplcea, Danais, and P. demoleus 

 in the aviary. But all three were uneaten when the bird went to roost, 

 and also when I looked next morning. 



After this the bird was transferred to the Alipore Zoological 

 Gardens, where it still is. 



Experiments with King-crow. 



The first bird of this species I got was sickly and soon died. Wot 

 however, before it had rejected a Danais chrysippus after tearing off the 

 wings, and eaten a Terias whole. 



The next bird, with which I experimented more than two years after, 

 was healthier and older, but did not do well in captivity. In fact, 

 when I ultimately released it, it was so weak as to fall a prey to a kite, 

 a bird it would naturally attack and tease. It was kept part of the 

 time in a small, and part in a large cage, both with upright wires, and 

 fed on maggots and grasshoppers. I performed with it the following 

 experiments, also towards the end of 1896. 



November 16th. — I gave the bird two Papilio demoleus and a 

 Danais limniace. The Papilios were very soon eaten, though the bird 

 was wild, (and hungry too, I think) ; the D. limniace was not eaten. 

 I then put in another P. demoleus and one each of Danais genutia and 

 D. chrysippus. The bird tore off the wings of the P. demoleus, but left 

 the body ; it did not touch the Danaids. I then put in a Junonia and a 

 Catopsilia ; the latter was eaten at once, but the former soon disappear- 

 ed also and not long after the body of the P. demoleus also, the Danaids 

 being untouched. I left these in the cage, as night came on. 



November \lth. — The Danaids left overnight were gone to-day, but 

 I do not know whether the bird ate or the sweeper removed them. I 

 gave the bird in the morning, when it was hungry, a Danais genutia 

 and a D. chrysippus ; it immediately took the genutia and tried to swal- 

 low it whole. It must have eaten both, for they disappeared, and I 

 saw it swallow a body after picking off the wings. I then put in three 

 D. chrysippus, one of which had been refused by the Bhimraj (see 

 Bhimraj nnder this date) and the Papilio aristolochise also refused by 

 that bird. I soon saw the King-crow eat one D. chrysippus, and not 

 long after found only one left out of the three, with torn wings. The 

 P. aristolochise was uneaten. Yet the bird soon after ate grasshoppers 

 when given. 



By the evening only the P. aristolochise was left, with more torn 

 wings than before. I then gave the King-crow, which should have been 

 hungry, a non-mimetic specimen of P. polites, which it at once ate, 

 nearly whole. I then put in a Delias eucharis and a Catopsilia, the latter
