844 MK. R. I. POCOCK ON THE 



just as I thought he was going to swallow it, he spat it out with 

 profuse salivation. 



One given to another Capuchin (sp. a) was licked and dropped. 



One given to a third Capuchin (sp. b) was chewed up and 

 swallowed without any signs of dislike, the larva being not even 

 taken from his mouth for examination. 



Another given to the same monkey was also eaten without any 

 signs of dislike, although he held it in his hands and licked it 

 several times before finally putting it into his mouth and chewing 



it. 



June 24, 1909. Repeated experiments with monkeys. 



The two Capuchins (sp. a), the Dent's and Mona Monkeys 

 behaved exactly as before. They took the larvae, smelt them, 

 tasted them once or twice, and finally rejected them. The 

 Capuchin (sp. b) which had previously eaten two, again ate one 

 without signs of relish or the opposite. I then oflered a larva 

 to another Capuchin of the same species (b) and he treated it as 

 the specimens of the species a and as the Mona had done, that 

 is to say smelt it, tasted it, rubbed it in his hands, repeated the 

 tasting once or twice, and finally dropped it. His behaviour 

 showed that the difiference between the behaviour of the first 

 example of sp. b, which ate the larvte, and that of the examples 

 of sp. a, which I'ejected them, is not attributable to the specific 

 distinction between the Monkeys as might have been supposed, if 

 only one specimen of sp. b had been available for experiment. 



One given to Canadian Jay, taken, pecked, jammed into a 

 cranny, and repeatedly pecked ; then dropped. When the bird 

 made no attempt to fetch it, the keeper picked it up and placed 

 it on the perch, when the bird again seized it, jammed it into a 

 cranny in the perch, and left it. 



One given to Red-backed Shrike was eagerly seized, and after 

 one or two pecks was left, the bird retiring and wiping his beak 

 on the bars, as the Canadian Jay had also done. 



Two given to Silver Pheasant were taken and pecked, and after 

 a good deal of rubbing in the earth were eaten. 



One given to Prince of Wales' Pheasant was taken, pecked and 

 rejected. 



One o-iven to Piping Crow was pecked and tasted and rejected, 

 after a good deal of shaking of the head and wiping of the beak 

 on the part of the bird. It was then picked up by a Magpie, 

 which after a taste or two stowed it away under a large stone, 

 and built up the hole with pebbles. 



One given to Bufi" Laughing Kingfisher was taken and tasted, 

 but rejected with much bill wiping. Tried and rejected in the 

 same way by a second specimen of this bird. 



One given to Common Laughing Kingfisher was taken and 

 tasted, but finally rejected. 



One given to Dial Bird was finally rejected aftei' a great deal 

 of pecking and tasting, accompanied by much shaking of the head 

 and wiping of the bill,
