through his bill and dropped it ; but ran through his bill for 

 a few seconds and sicaUoiced a fresh one. Rejected another 

 dry one, but tasted and at once swallowed a further fresh one 

 and a Precis madagascariensis. He then took a Catopsilia 

 florella, tasted it, and turning right round to (\ who was 

 behind him, gave it to her ; tasted a second one and ate it 

 himself ; accepted a Papilio angolamis, ran it from side to 

 side in the point of his bill, bowed to me several times, still 

 holdinor it, then ran it through his bill again and swallowed 

 it ; took the very favourite moth, Splmutomorpha cMorea, 

 away from C and swallowed it himself; accepted a i?_?/?>//a, 

 but allowed C to have it; and accepted five larval migratory 

 locusts. He swallowed the first three of them, but deliberately 

 turned round and passed on the fourth to C Tlie fifth he 

 also offered to C, but, on the latter bird's ignoring it, he ace 

 it himself. 



C tasted and readily swallowed two Precis a7'ta.via. I 

 offered a third. This time she was watching the crack 

 eagerly and darted her bill right into it, seized the butterfly 

 directly it appeared on the other side, and promptly swallowed 

 it, treating a fourth in exactly the same way ; then wrenched 

 from the forceps the abdomen of the P. natalensis, of which 

 A simultaneously secured the thorax, swallowed it; accepted, 

 tasted, and readily swallowed the Catopsilia jiorella handed 

 her b}"- A, and a second, also a Papilio angolanus, a Terias, 

 two more P. angolanus, two Byhlia (species not stated, but 

 probably goetzivs), and an Ypthima near impura ; accepted a 

 moth. Spiling omorplia chlorea, but (as already related) had it 

 taken from her by A ; then took from A, with his apparent 

 consent, a Byhlia ; accepted and ate the first larval migratory 

 locust offered her by A, and ignored the second. 



B, on my accidentally dropping a wingless Pr^m- natalensis 

 at the commencement of the experiment, rushed forward 

 from the back of the cage, picked up, in apparent mistake 

 for it, the wingless Papilio angolanus that A had just rejected, 

 tasted it, and swallowed it — then found and ate the Precis, 

 too. Later in the experiment she tasted and ate a Terias 

 hrigitta.
