disabled, comprising specimens of Danais ehrysvppus, D. genutia, D. 

 limniace, and Euploea, with Papilio demoleus, Huphina pihryne, Gatopsilia, 

 Junonia, &c. There was no doubt that these latter non-warningly- 

 coloured 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 Gatopsilia or other palatable species. 



I offered two specimens of the female of Nepheronia hippia. The 

 first one, which was displayed, was passed over by a bird in favour of a 

 Gatopsilia, 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 Gatopsilia, 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 caugbt with some trouble as they fluttered. 



This day they four times refused a red, black and white bug 

 (Dysdercus sp ?). 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-ooloured 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 band. 



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, a#d 

 eaten.
