disabled, comprising specimens of Danais chrysippus, D. genutia, D. 
limniace, and Euploea , with Papilio demoleus, Huphina phryne, Catopsilia , 
Junonia , &c. There was no doubt that these latter non-warningly- 
eoloured species were preferred to Danais and Euploea. All as far as 
I saw were eaten, while though, the Danainae were picked at, and I 
think one or two of them eaten, I often saw them looked at and then 
passed over in favour of a Catopsilia or other palatable species. 
I offered two specimens of the female of Neplieronia hippia. The 
first one, which was displayed, was passed over by a bird in favour of a 
Catopsilia , though the same individual then tried and ate it. The 
second specimen, whose wings were half closed, did not seem to be 
noticed at first, but on being thrown to a bird it was picked up and 
eaten. I saw one bird, eating a Catopsilia , leave it and try a Danais 
genutia , and then return to its former prey. I saw one bird try un¬ 
successfully to catch an uninjured butterfly on the wing; decapitated 
specimens were caught with some trouble as they fluttered. 
This day they four times refused a red, black and white bug 
{ Dysdercus sp P). I thought Euploeas were least disliked of the unpalat¬ 
able butterflies given. 
January 17th. — This morning I found lying about wings of the 
butterflies rejected overnight; but these birds may not have eaten the 
bodies. 
I put out several Danais genutia , which were not regarded with 
favour, though one or two were taken. A bird which had left one took 
and ate a skipper. 
Another „protective butterfly was eaten in preference to Danais 
genutia and D. chrysippus. A Junonia was eaten readily. 
A male Elymnias undularis was eaten readily. 
Two D. genutia were rejected, but a protectively-coloured species 
taken. 
Some specimens of Huphina phryne were taken readily and eaten. 
Two birds tried to catch a D. genutia on the wing. 
A bird took a Junonia from my fingers and apparently ate it. 
Another protectively-coloured species then taken. 
Another attempt made to catch a flying D. genutia. 
Two male specimens of Elymnias undularis taken in succession from 
my hand. 
D. genutia was taken from my hand, but it escaped, and three birds 
tried to catch it. 
Another protective species was taken. 
A specimen of a protective species was taken, squabbled for, and 
eaten.
