1896.] Frank Finn — Theory of Warning Colours and Mimicry. 45 



Ceased experimenting with this lizard,- which I killed to feed some 

 birds. 



A month afterwards I commenced experimenting with lizards in 

 their natural state in the Museum compound, the butterflies being 

 usually disabled by having the anterior nervure of the fore-wings 

 broken. Owing to the above-mentioned deliberation of the lizards' 

 movements, the work of watching them was very tedious, and I did not 

 always see the final result. I commenced experiments by offering a 

 cockroach, as stated below. 



ExPEBlMENTS ON LlZAJRDS AT LlBEETY. 



July 7 th. — Gave a decapitated cockroach to a big lizard in the com- 

 pound. The lizard rushed to the insect, and after a little hesitation, 

 apparently on account of the kicking legs, seized and carried it off ; I 

 did not see what then happened, as the lizard on my approach went up 

 a shrab. 



July 9th. — A Papilio demoleus and a Danais genutia offered to a 

 lizard, were not attacked. I therefore offered them to another. The 

 Danais disappeared when I was not looking, but it might have fluttered 

 away. I took away the other. 



July \0th. — Offered a Danais chrysippus to lizards. One attacked 

 and let it go (or lost hold) once or twice ; then this lizard was attacked 

 by a bigger one and a scuffle ensued, and the lizards ran off fighting 

 and left the butterfly, which did not seem hurt, and was not eventually 

 taken, though I let it remain for a little. 



July 12th. — In the morning, put a plain-coloured species (Junonia 

 I think) and a Danais chrysippus near a large Galotes. The lizard 

 took the former, which was nearest, and went off with it. 



I then offered a D. genutia to another Galotes, which took and ate it. 



I gave another D. genutia to a smaller specimen of this lizard, 

 which seized it and ran off with it in its mouth as after a little time 

 1 approached. 



I then offered an Euploea to another large lizard. After a little 

 time he attacked it, but it got away, and he pursued it ; then another 

 smaller lizard appeared and possibly there was a fight. If the butter- 

 fly was taken, this was done quickly, for I could not find it, nor did I 

 see it in the possession of the lizards. 



I then offered a D. limniace to the first of these two lizards, but it 

 did not offer to touch it. I put the same insect not far from a smaller 

 lizard, which bit off a piece of wing, and then after a little while went 

 away. I put the same specimen near another, which apeared to see it, 

 and yet ran past, possibly attracted by a fight between lizards further on.
