whether she cared for it or not. The next time, however, she swallowed it (a fairly 

 thick piece). I then cut out and ofiered a small scrap of the snake's flesh without 

 skin. This she tasted very deliberately and rejected, but she ate it on its being ^ 

 reoffered. The next piece she again tasted and rejected, and thenceforth would 

 have nothing to do with it, refusing it most obstinately. She very readily, however, 

 ate a Neptis agatha and a Terias senegalensis (I had unfortunately nothing more 

 unpleasant than the latter to offer, but the bird was still distinctly hungry), followed 

 by four smallish grasshoppers. She then refused uttei-ly with shakes of the head to 

 touch the small piece of snake-flesh, but readily accepted and ate another Terias, 

 once more persistently refusing the piece of snake. 



A little later, after several more grasshoppers, she refused a Terias but eagerly 

 accepted and ate a Neptis agatha, Mycalesis campina S and $ , and the Terias 

 reoflered. After ten more grasshoppers she refused repeatedly and obstinately to 

 touch a Terias, but most readily accepted and ate a Neptis agatha. 



[Summary : — 



1. N. agatha (M. canijnna perhaps the result of stimulation). 



2. Terias senegalensis. 



3. Night-adder. 



The fear shown by an occasional snake-eater at the unexpected appearance of a 

 bit of snake was interesting.] 



Exp. 93. — October 12. The bird was obviously hungry. She crushed well 

 hesitated for a few seconds over, then threw right away a S Lamipyris mar- 

 gineptennis, i-eadily accepted and ate Terias senegalensis, twice refused but, chano-ing 

 her mind, the result doubtless of her hunger, accepted, crushed lightly, and at 

 once threw away a second Lampyris, crushed and readily ate a Mylothris yxdei, but 

 again tasted and rejected the Lann-pyris, as also Amaitris doviinicanus. 



She then ate four small pieces of fresh meat (lamb) and refused the next but 

 though coaxed into eating it flatly and finally refused to have anythino- to do with 

 the next. She refused equally obstinately to touch a Terias, but readily accepted 

 and ate a Mycalesis campina, afterwards once more refusing the Terias. I then 

 gave her six grasshoppers, after which she fairly readily ate another Mycalesis 

 campina, then crushed well and finally flung away a wood-boring longicorn 

 Ceroplesis caffer, of which I had removed one elytron, afterwards utterly and 

 obstinately refused to have anything further to do with it. The beetle in question 

 smelt slightly of sandal-wood and a clear white liquid exuded when the elytron was 

 removed. 



Ten minutes later she tasted and at once flung away a small piece of lamb's 

 meat, ate eleven small grasshoppers and refused utterly to touch another ; crushed 

 and rejected Papilio angolanus, refused for a second then crushed and very readily 

 ate an Arrugia hasuta $ , tasted and rejected Papilio lyceus; refused for a second 

 undoubtedly through disinclination, then accepted and readily ate a S Arriiqia 

 basitta, refused without tasting Hypolimnas wahlbergi and for a second Precis 

 artaxia, but then, changing her mind, accepted and ate the latter; accepted 

 H. ivahlbergi with a little hesitation, but having tasted it appeared quite reassured
