634 F. Finn — Experiments with various Birds. [No. 4, 



evening, I put in about twenty Euplceas and a male Hypolimnas. This 

 last was singled out for persecution by the Liothrix and a Yellow- vented 

 Bulbul, and though its size and activity gave trouble, it was at last, 

 falling in the water vessel, caught firmly by one of the former birds, and 

 eaten by a bird of this species, which threw up the body once, but 

 eagerly took it again. 



Meanwhile the other Yellow- vented Bulbul was worrying an Euplcea, 

 which I suppose it ate. I saw no other Euplceas eaten at the time, and 

 both the unoccupied Bulbul and the other Liothrix wanted to get the 

 Hypolimnas from its owner. I saw Euplceas taken and relinquished by 

 Liothrix at least twice, though they ate rice and milk (for the last few 

 days I have been giving them sweetened sop made thus or with bread, 

 which seems much to their taste aud probably lessens their readiness 

 for butterflies). 



The dry body of one aristolochise was still about. At night about a 

 dozen Euplceas were still left in the cage. 



V. Next morning some of the Euplceas put in over-night were 

 gone, but two or three remained alive. In the evening all were eaten. 

 I then put in a male Hypolimnas and a female Nepheronia hippia. The 

 former was first attacked by a Liothrix, but before it succeeded in 

 catching it, another seized the mimic, which had settled with its wings 

 closed while the other was being chased. 



I saw a Bulbul in possession of both, but the Hypolimnas was 

 snatched from it by a Liothrix just as it had nearly got rid of the wings. 



I put in five Papilio aristolochise and two non-mimetic specimens 

 of P. polites. One of the latter was soon knocked into the water, and 

 another taken and torn by a Liothrix, which (or another of the same 

 species) was about to eat the body, when a Bulbul snatched it and 

 appeared to eat part. 



I found the bodies of four Euplceas in the cage, as well as the old 

 P. aristolochiae, though the birds had much fewer maggots this morning 

 than usual. 



I took the first P. polites, still living, out of the water and laid it on 

 the ground. But both it and the P. aristolochise were untouched when 

 the birds roosted. 



To-day they ate none of the plantain supplied, seeming to prefer 

 the rice and milk. For a day or two I have noticed little plantain was 

 eaten. 



VI. Next day the P. polites was not to be seen, but none of the 

 five P. aristolochise had been eaten, and two at least were still alive. 



I then put in five Danais chrysippus and three D. limniace, which 

 were not touched.
