The Babblers then took and left two Papilio aristolochiae, though 

 by this time all the Danaids and the Papilio polites were more or less 

 torn up and eaten, the latter all but the wings, I think. One of the 

 P. aristolochiae was not even killed at first. There was other food in 

 the cage. 



(d.) Offered the birds a Danais chrysippus and a Catopsilia. 

 Two of them came at once, so 1 was not quite certain; but 

 I think the latter was preferred, 

 (e.) Repeated the experiment with two D. chrysippus and one 

 Catopsilia. The latter was distinctly chosen by the first 

 comer. 

 ( /.) Repeated the experiment with two D. chrysippus and a 

 Junonia. The first comer (young bird) took a D. chrysippus, 

 the second the non-warningly-coloured species. 

 (gr.) Put in a Junonia and one D. chrysippus. One bird took 

 one and another the other. 

 A Babbler took a Papilio polites readily. I saw no traces of the 

 P. aristolochiae about by this time. 



(h.) Offered the Babblers a Papilio polites and two Danais chry- 

 sippus. The two first comers took the latter ; but the 

 former was soon taken. 

 (i.) A Papilo demoleus and a Danais chrysippus offered. One bird 

 came, and chose the former ; but the Danais was soon taken. 

 (j.) One Catopsilia and one D. chrysippus were offered. The 

 former was chosen by the first comer. 

 There was some rice still left in the vessel at this time. 

 VI. (a.) Offered to birds, in my hand, one specimen each of 

 Danais chrysippus, Papilio demoleus, and P. polites. The last named 

 was taken first, and then the Danais. 



(6.) A pi'otectively-coloured butterfly was offered in my hand 

 to the birds, together with a D. chrysippus. The Danais 

 was taken first. 

 (c.) A Danais limniace and a Papilio demoleus were offered ; the 



latter was taken first. 

 (d.) A protectively- coloured butterfly (same species as above) ; 

 again offered with a D. chrysippus. The Danais was taken 

 first ; it was nearest to the bird, 

 (e.) Same experiment repeated with another D. chrysippus; the 



Danais again taken first. 

 (/.) Same experiment repeated; this Danais was also taken first, 

 though the other species was eaten readily by the next bird. 

 (g.) A small satyrid butterfly offered with Danais limniace in my 

 hand. The former was taken first.
