( g .) Put in another D. chrysippus and a small fritillary, Atella 
phalanta. A bird took and ate the latter; the former was 
unregarded for a little time at least, then a bird took and 
ate at least some of it. 
(7r.) A Babbler took and pulled about a Delias eucharis, but then 
left it. I offered it again, and it was refused by a bird 
or two, though another appeared to eat part of it. 
I then put in one Danais genutia , two D. limniace , and several 
D. chrysippus , which were immediately attacked as they fluttered about. 
All of these last mentioned were soon killed and torn to pieces, and I 
saw at least three eaten, though the birds had rice, &c., in the aviary. 
IV. The birds had had no insects but a fly or two when I gave 
them (dead). 
(a.) Two Danais chrysippus and one Papilio demoleus. The latter 
was taken first. I took the former away and 
(to Presented them again with another P. demoleus. Two birds, 
one young, went for the Papilio ; the older got it, and then 
the other bird took a D. chrysippus. 
(c.) Put in two more D. chrysippus and a P. demoleus. A bird 
advanced and deliberately chose the latter. 
(d.) Two more D. chrysippus and a P. demoleus were put in. 
The latter was taken first. 
( e .) Same experiment repeated with same result. 
(f.) One D. chrysippus and one P. demoleus put in; first comer 
chose the latter. 
The birds did not seem to me very eager for the Papilios , though 
they so obviously preferred them. All the butterflies were eaten, or at 
least torn to pieces, and I saw no bodies lying about. There was rice 
in the food-bowl notwithstanding. 
V. Offered the Babblers a Papilio aristolochiae; a bird took it 
and tore off the greater part of the wings, but left the body. Another 
took this and tore off the thorax, and left the abdomen. A Danais 
limniace was then eaten, at least most of the body, I think by one of 
the individuals which had refused the other. 
(a.) Put in the aviary two Danais chrysippus and a Papilio demoleus. 
One of the former was first taken, then the Papilio. 
(5.) The experiment was then tried with two D. chrysippus and 
a Papilio polites* A D. chrysippus was first taken, then P. 
polites by a young bird. 
(c.) Two D. chrysippus and a male Elymnias undularis were then 
put in. D. undularis was taken first and swallowed whole. 
These sets of butterflies were put in dead.
