vomited parts of a lizard (Mabuia striata), but the lizard was never- 

 theless entirely eaten. The mongoose was unwilling to eat birds 

 and refused to attack a conspicuous milliped (Spirobolus). An 

 obscurely colored milliped also was refused by a lemur (Galago). 



Another of Finn's experiments concerning the tastes of mammals 

 for insects deals with a tree-shrew {Tupaia ferruginea). 42 The 

 conclusion is: "It is obvious that this animal had a very strong 

 objection to the 'protected' Danainse and Papilio aristolochice, as 

 it. so constantly refused them" (p. 532). This is a fair summary of 

 the experiment except as it applies to Papilio aristolochice, the record 

 for which was A 2 R2. 



Marshall and Poulton have published 43 accounts of experiments 

 with a mongoose {Herpestes galera), baboons, and a monkey (Cerco- 

 pithecus pygerythrus) . The mongoose tested by Marshall (pp. 376- 

 378) refused but one insect consistently and had only two trials 

 with that. The animal was tested with birds as food and refused 

 five out of ten kinds offered. Two of the five refused have colors 

 of the type called warning and this is peg enough upon which to hang 

 some speculations as to distastefulness. Nothing is said about the 

 equally conspicuous colors of two of the species eaten, viz., Nettopus 

 auritus, blackish-green, white and rufous; and Saxicola pileata, 

 chestnut, black, and white. The results of single trials of several 

 insects with Cercopithecus pygerythrus are recorded on p. 379, and 

 pp. 380-392 are devoted to an account and dtscussion of more 

 extended experiments with baboons. Poulton tabulates the Cole- 

 optera accepted and rejected by the baboons, and from these tabula- 

 tions it appears that about 75 per cent, of the beetles rejected had 

 warning color patterns, as did about 55 per cent, of those accepted. 

 It is unfortunate that there are no records of the natural food of 

 these African mammals that can be used as a check on the experi- 

 mental results. 



MIXED GROUPS OF ANIMALS. 



Brief notes on experiments with a marmoset and lizards are 

 included in E. B. Poulton's description of the "means of defence 

 adopted by the larva of Stauropus fagi" and the "defensive value of 

 'tussocks' of Orgyia and the associated black intersegmental mark- 

 ings." 44
