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).” The 
conclusion is: “It is obvious that this animal had a very strong 
objection to the ‘protected’ Danaine and Papilio aristolochie, as 
it so constantly refused them” (p. 532). This is a fair summary of 
the experiment except as it applies to Papilio aristolochie, the record 
for which was A2 R2. 
Marshall and Poulton have published“ 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 Sazicola 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 discussion 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 fag” and the “defensive value of 
‘tussocks’ of Orgyia and the associated black intersegmental mark- 
ings. ”’#
