532 P. Finn — "Experiments with a Tupaia and a Frog. [No. 2, 



it had been taken by the other Tupaia. This was in fear of my animal, 

 and had had none of the butterflies. 



I put in another P. aristolochise, which was smelt at by both the 

 Tupaias, but not killed, though my animal then ate a Catopsilia given it. 



Some time later I found this P. aristolochise dead, and slightly 

 bitten, but quite whole, having evidently been rejected. 



It is obvious that this animal has a very strong objection to the 

 " protected " Danainse and Papilio aristolochias, as it so constantly 

 refused them, and that in the case of the former absolutely, unlike the 

 Babblers dealt with in my first paper (J. A. 8. B. 1895, Pt. II, p. 

 344), which birds, caged under much the same conditions, generally 

 showed their dislike of the Danainse merely by preferring other species. 



Experiments on a Bull-Frog. 



My experiments on this amphibian, which Dr. Alcock had been 

 keeping for a little time for use in the Museum, and which he kindly 

 allowed me to test upon this subject, were few and not long continued. 

 But such as they are, I have thought well to insert them, if only for 

 completeness. The experiments were made soon after I came to India, 

 in 1894. 



November 2nd. Offered a Danais chrysippus to the frog, which was 

 being regularly fed on cockroaches ; the butterfly was not touched. 



November 10th. I put into the cage of the frog, instead of its 

 usual meal of about a dozen and a half of cockroaches (Periplaneta 

 americana), one cockroach only, and a Delias eucliaris. Before long 

 both insects had disappeared. 



I then put in another D. eucharis, a Danais chrysippus, and a smaller 

 non-warningly-coloured butterfly. Later on I found the Danais was 

 gone. The others apparently remained. 



November llth. No butterflies left in the frog's cage. 



November 12th. I put in the frog's cage a Tenets, three Delias 

 eucharis, and three cockroaches. 



November \Zth. To-day there were no insects in the cage, and 

 about five cockroaches were put in by Dr. Alcock, and a Danais chrysip- 

 pus by myself. 



November \4ith. The Danais chrysippus given to the frog yesterday 

 was still there, alive; I saw none of the cockroaches, but did not 

 specially look for them. I took out the Danais. 



November Ihth. To-day I put a female Hypolimnas misippus and 

 a cockroach in the frog's cage; there were also two or three more 

 cockroaches. I did not note what happened next day. 



November 17 th. No insects left in the frog's cage. I now put in
