refused to touch a Precis madagascariensis, but recognised with evident pleasure 

 and accepted and ate a second Precis natalensis © f. She then accepted a 

 Gharaxes pollux, crushed it well and held it in hei- bill for two or three minutes, 

 being evidently loath to relinquish it, yet feeling that she could not find space 

 for it. Finall}^ she dropped it. She then refused a Charaxes candiope, but in the 

 end, attracted by its violent fluttering, accepted and ate it; took in her bill and 

 dropped through sheer repletion a Charaxes pollux, a Charaxes cithceron, and a small 

 queer termite, and refused persistently even to taste a very favourite grasshopper. 



I reoffered all four insects three times at intervals of ten minutes, but they were 

 each time ignoi'ed.

Exp. 91. — September 30. Fed with grasshoppers till she would absolutely not 

 touch another. She then most obstinately refused to taste Papilio angolanus, 

 accepted Papilio demodocus, subjected it to very prolonged crushing, being quite 

 evidently doubtful whether to swallow it, but finally did so ; readily ate a Charaxes 

 hrutihs, obstinately refused to have anything to do with a Papilio demodocus and a 

 Papilio lyceus ; crushed and readily ate a Charaxes j^ollux ; again refused to 

 touch Papilio demodocus, Papilio angolanus, and Papilio lyaius ; readily ate a second 

 Charaxes polliuv; held for some time a,nd finally dropped a Precis artaxia; refused, 

 then accepted and ate with relish a large moth, Nyctipao 7nacrops, refused without 

 tasting Precis artaxia ; crushed, held, a,nd finally swallowed Charaxes ca7idiope. 

 She was evidently nearly replete. Three minutes later J reoffered the Precis 

 artaxia, which was this time eaten readily, while Papilio lyceus, Papilio demodocus, 

 Papilio policenes, and Papilio angolanus were obstinately refused without tasting, 

 and Leuceronia thalassina tasted and rejected.

It is probable that P. artaxia was also prefei'red to P. policenes and L. thalassina,

Exp. 92. — October 10. 1 offered the roller (hungry) a section of a smallish 

 "night-adder,"' about Ig in. long. Usually a quite imperturba,ble bird, she now 

 at once dashed to the back of the cage with great fright and scurry of wings, 

 but, gradually recovering herself, returned to her usual perch and after very 

 slight hesitation accepted the piece, crushed it once or twice, and threw it away.
