left. Even two of these were ultimately taken, and I suppose eaten ; T did 

 not watch the whole process. The other, a D. chrysippus, was at the top 

 of the cage, and possibly hard to get; I took it out. The young Babbler 

 took, instead of a Danais genutia, a specimen of Nichitonia xiphia, which 

 he seemed not to like. However, later on I could only find a few bits 

 of wing left of all the butterflies I had put in, so I suppose it was 

 eaten after all. The birds had had some grasshoppers first. 



III. Put a Danais genutia into the aviary, where a Babbler took 

 it and ate it whole. A D. chrysippus was taken by a Babbler, which 

 was pulling off the wings with no great eagerness, when another took 

 it away and ate the body. An Duploea (rather crushed) was eaten 

 readily enough, with part of the wings, by a Babbler. I then put 

 in several D. chrysippus and genutia, and the birds ate them all and 

 fought over them. I saw one throw up a body two or three times before 

 swallowing it, A T). chrysippus was first taken when I put in two of 

 each kind (D chrysippus and D. genutia) dead. The birds had had 

 some grasshoppers some hours before. Some time afterwar-ds I killed 

 and put in — 



(a.) One each of Danais chrysippus, genutia, and limniace, Euploea, 



and Catopsilia. A bird snatched the D. limniace before I 



took my hand away, and the Catopsilia was not, I think, 



the next taken. The Euploea was swallowed whole. 



(b.) Two D. chrysippus and a large brown species put in; a bird 



first took the latter, 

 (c.) The same two D. chrysippus were put in together with a 

 Junonia. Two birds advanced at once and one took the 

 Junonia, the other a D. chrysippus. The Junonia was 

 eaten before my eyes, and I saw the other begun upon. 

 (d.) 1 repeated this experiment with two D. chrysippus and another 

 protectively-coloured specimen. This latter was taken by 

 the first bird which came. About this time I saw a bird 

 eat the body of a Danais, and soon found two lying about. 

 The birds pecked but did not seem to care for them. 

 (e. ) I put in a Catopsilia and two D. chrysippus ; two or three 

 of the birds came at once. One took the Catopsilia and 

 another a D. chrysippus. 

 (/. ) Put in a Catopsilia and one D. chrysippus. Tiie first comer 

 took the former, and immediately afterwards the latter 

 was taken. The Catopsilia was eaten at once with some 

 of its wings. The body of the other was eaten after 

 some rubbing ; I do not know whether the eater was the 

 individual which took it.
