proofs of this conclusion. Thus, the chamEeleon which 

 has been previously referred to had just been imported 

 into this country when I received it, and it had probably 

 never seen a-common hive-bee in its life. I put a living 

 bee in the cage, and the lizard immediately began to 

 watch it, and, as soon as it had settled, captured it 

 with a dexterous shot of its long tongue. As the 

 tongue was being withdrawn with the bee adhering to 

 the sticky pad at its extremity, the chamseleon was 

 stung and immediately showed signs of discomfort, 

 throwing its head from side to side, and thus jerking 

 the bee off. For many months after this I put 

 bees into the cage at irregular intervals; but the 

 chamaeleon's education in this direction was complete, 

 the single experience was sufficient, and no other bee 

 was touched. 



Similar highly-coloured and specially defended features 

 occur in certain Marine Animals 



A very similar example from an entirely different 

 group of animals has been recently brought forward 

 independently by Professor W. A. Herdman ^ and Mr. 

 Garstang. These naturalists suggest that the brightly- 

 coloured dorsal papillae of Eolids (Nudibranchiate 

 gastropods) have the same meaning as the ' tussocks ' 

 of Orgyia, being far more conspicuous than the rest 

 of the body, easily detached, and often reproduced by
