(I) Same experiment repeated. Protective species taken first, 
and eaten, by the same bird. 
This bird again ate one of this Satyrid ; though there were Danais 
limniace and chrysippus uneaten in the cage. A Catopsilia 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 Catopsilia. Latter chosen. 
(6.) One D. genutia one Catopsilia. Former chosen, by young bird, 
(e.) Same experiment repeated. This time the butterflies were on 
my hand, held on the floor; a bird swooped from the 
perch on the Catopsilia , 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. 
(f. ) One Huphina phryne , one D. chrysippus. Former taken first. 
( g.) One Papilio demoleus , one D. 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 liberty. 
January 1 6th. — As the birds were hopping about the garden eating 
termites, &c., I gave them a number of butterflies, mostly dead or
