(l.) Same experiment repeated. Protective species taken first, 



and eaten, by the same bird. 



This bird again ate one of tbis Satyrid ; though there were Danais 



limniace and chrysippus uneaten in the cage. A Gatopsilia was then put 



in, and the same bird took and began upon.it, when it was taken and 



soon swallowed by another. 



Some Danais genutia and limniace, Euploea, and Delias eucharis 

 were then thrown in, but though one or two birds pulled them about, 

 I saw none eaten. The birds were now going to roost. They had had 

 no insect food before on this day, but a number of cockroaches the 

 day before. 



X. Offered the birds — 

 (a.) One Danais chrysippus, one Gatopsilia. Latter chosen. 

 (b.) One D. genutia one Gatopsilia. Former chosen, by young bird. 

 (r.) Same experiment repeated. This time the butterflies were on 

 my hand, held on the floor ; a bird swooped from tho 

 perch on the Gatopsilia, and took it. 

 (d.) Same two species offered. Both were taken at once, 

 (e.) One protectively-coloured specimen, one D. chrysippus. For- 

 mer deliberately taken. 

 (/. ) One TLuphina phryne, one D. chrysippus. Former taken first. 

 (<jf.) One Papilio demoleus, one jD. chrysippus. Former chosen, but 



birds not eager. 

 (h.) Same experiment repeated. As the first comer was hesita- 

 ting, and seeming to prefer the D. chrysippus, another 

 snatched the P. demoleus 

 (i.) One small protective Satyrid, one D. chrysippus offered. The 

 first comer in the last experiment deliberately chose the 

 former, though the Danais was nearer. 

 ( j.) Papilio demoleus offered with Euploea. Latter taken first. 

 Put in three Euploeas, one Danais genutia, one D. limniace. Last 

 chosen deliberately by young bird. I threw in two more Euploeas and 

 two D. limniace. The former were this time seized, but one bird soon 

 left its prey, and I did not see the other specimen eaten, though I saw 

 one Euploea swallowed whole. 



In the afternoon of the following day I released these birds, which, 

 as observed in the beginning of this paper, still continued about the 

 place. Thus I was enabled to make the following experiments with them. 



Experiments with Babblers at lieertt. 



January lQth. — As the birds were hopping about the garden eating 

 termites, &c, I gave them a number of butterflies, mostly dead or
