The results of most of the earlier experiments with various animals 
are brought together by Prof. E. B. Poulton in a paper entitled, 
“The Experimental Proof of the Protective Value of Color and 
Markings in Insects with Reference to their Vertebrate Enemies”’ 
(Proc. Zool. Soc. Lond., 1887, pp. 191-274). It is convenient to 
review these experiments collectively. Those covered by Poulton 
are as follows: 
Butter, A. G. Remarks upon certain Caterpillars, etc., which are 
Unpalatable to their Enemies. Trans. Ent. Soc. Lond., 1869, 
pp. 27-29. 
Animals experimented with were Lacerta viridis, frogs, and spiders. 
In part previously published in Ent. Monthly Mag., 5, 1868, 
pp. 131, 132. 
Pouuton, E. B. Diary of observations during 1886. P. Z. S. 
Lond., 1887, pp. 269-274. 
Using Lacerta muralis, L. viridis, and Hyla arborea. The earlier 
sketch of some of the results of these experiments is: ‘‘Some 
experiments upon the protection of insects from their enemies 
by means of an unpleasant taste or smell.” Rep. British A. A. 
S., 1886 (1887), pp. 694, 695.

on the relation between the Color and the Edibility of Lepi- 
doptera and their Larve. Trans. Ent. Soc. Lond., 1869, pp. 
21-26. 
The birds used were seven species of finches, one weaver bird, 
one muscicapid, one pipit, and one thrush. Few of them are 
highly insectivorous species.

Birds used as in his previous experiments.

Lond., 1887, pp. 268, 269. 
Experiments with lizards: Lacerta viridis, L. agilis, and Zootoca 
vivipara.

Vol. I, pp. 328-341. 
Principally experiments with Lacerta viridis. 
The main burden of the first half of Poulton’s paper is the searching 
of the results of these experiments for support of ‘“ Wallace’s original 
suggestion ‘that brilliant or conspicuous larve would be found to 
be refused by their enemies’” (p. 196). In the preliminary sketch®
