622 F. Finn — Experiments with various Birds. [No. 4, 



When I put in the butterflies I had reserved, the Danais was 

 first attacked, then the P. polites; the P. demoleus was left a little 

 time, then it disappeared, as the other two species had done. 



III. I put in two Danais chrysippus and one D. genutia and three 

 non-warningly coloured butterflies. The Liothrix took the latter first ; 

 then one took the D. genutia. The female Button-Quail apparently 

 ate the two D. chrysippus, but she had no fair chance at the others. 



A Papilio aristolo chide put in was not touched by any of the 

 birds. But a few hours after only a wing was left. 



I put in one D. chrysippus and Euploea and two or three non-warn- 

 ingly-coloured ones. These were taken first. 



I put in a female of N. hippia, which was eaten by a Button- 

 Quail. 



I put in some Danais with Hnphina phryne and other non-warn- 

 ingly-coloured specimens where the Button-Quails could have a choice ; 

 they did not seem eager for any, and certainly did not pick out the 

 non-warningly-coloured ones. A Liothrix went on tearing a Euploea 

 even among these, and I think ate it. 



Soon the Button-Quail ate a greyish butterfly, and a Liothrix 

 took one of the H. phryne, while two D. chrysippus were still left. 



An Elymnias undularis d* was in a corner, so I put it between the 

 two D. chrysippus, whence a Liothrix took it. 



In the evening I put in one each of D. chrysippus, D. genutia, 

 D. limniace, and Euploea, with a similar number of non-warningly- 

 coloured butterflies. The Liothrix deliberately picked out three of 

 these ; I did not see whether they got the fourth. The Button- Quail 

 swallowed the D. chrysippus. Then a Liothrix took the Euploea. 



IV. Next day, the Danais limniace put in yesterday had been 

 eaten. I put in an Euploea with two Nepheronia hippia $ . A Liothrix 

 took the Euploea first, before I was fairly out of the aviary. Only 

 the undersides of the N. hippia were visible. 



When all these were eaten, I put in two Papilio demoleus, two 

 P. polites (not much like P. aristolochise,) and two D, chrysippus. A 

 P. demoleus was first taken, by a Liothrix. P. polites seemed to be looked 

 at by these birds with some suspicion ; yet one was soon taken, and 

 another seized, pecked, and left, by them. This specimen, however, and 

 both the P. demoleus (one of which I think was swallowed by the 

 female Button-Quail) disappeared before one Danais did. This, how- 

 ever, afterwards disappeared. 



V. Next day, I put in one each Danais chrysippus, D. genutia 

 and Euploea, with three non-warningly-coloured butterflies. The 

 Liothrix took at the first attack the Euploea and two of the non-warn-
