(e ) Small brown Satyr id butterfly offered with D. genutia; former 

 was deliberately chosen. 

 Some specimens of Euploea, Danais chrysippus, and D. genutia, were 

 given alive, and immediately attacked by some of the birds. 



Two Papilio arislolochiae were tried and left, while some of the 

 Danainae above-mentioned wei'e being torn and eaten, though some were 

 still alive or uneaten. The birds had food by them at the time. Later 

 on offered them — 



(a.) A Danais genutia and a brown Satyrid species. The first 

 comer having a fair field, first took the former, and then 

 dropped it and took the other. 



(&.) Last experiment repeated ; two birds came at once, and the 

 Danais was first taken. 



(c) Offered a Junonia and a D. genutia ; the former was taken first. 



(d.) Put in one Gatopsilia, one Danais chrysippus, and two Papilio 

 polites (one mimetic of P. aristolochiae, and the other not). 

 The first comer deliberately chose the Gatopsilia ; the next 

 looked at the remaining three and turned away ; then a 

 P. polites was taken, and I saw it swallowed nearly whole — 

 I could not say whether by the same individual. The birds 

 had food by them. None of the butterflies previously put 

 in were to be seen. They did not seem very eager even 

 for Gatopsilia. 

 IX. Offered to the Babblers killed or disabled specimens as 

 follows : — 



(a.) One Danais chrysippus, one Gatopsilia. Former taken first. 



(b.) One D. chrysippus, one Gatopsilia. Latter taken first, by young 

 bird. 



(c.) Same experiment repeated ; Gatopsilia taken first. 



(d. ) Same experiment repeated with same result. 



(e.) One Danais genutia offered with one Gatopsilia. Latter deli- 

 berately taken first. 



(/. ) Ore female of Elymnias undularis, one Gatopsilia. Latter taken 

 first. The mimic also taken and swallowed whole. 



(g.) Papilio demoleus and Danais limniace. Former taken first. 



(7i.) Same species of Papilio and an Euploea. Papilio taken first. 



(i.) D. chrysippus and Papilio polites. Both of these were taken 

 at once. 



(j.) Same experiment repeated. The first comer took neither, the 

 second Papilio polites. 



(k. ) Protectively-coloured Satyrid and D. chrysippus. Former taken 

 first, and swallowed whole.
