PIWTECTIVE COLORAIIOX. 



Special Colour Resemblances, — Protection afforded by Eesemblances of this 

 kind chiefly efficacious against \''ertebrate Enemies. — Some Evidence 

 showing that Caterpillars are concealed by Protective Coloration from 

 Enemies. — Protective Coloration of the Iguana. — Protective Colora- 

 tion occasionally appears to be Superfluous. — Protective Eesemblance 

 in an Annelid. — Protective Coloration the prevailing device among 

 Leaf -feeding Caterpillars. — Protective Coloration in Man. — Green 

 Colour of the Moth. — Longitudinal Striping of Caterpillars. — Longi- 

 tudinal Striping found in all the species of the BiitterSy Family 

 SatyridfB. — These Larv£e usually feed by Night and often conceal 

 themselves by Day. — Internal-feeding Larvse sometimes Striped. — 

 Striping sometimes occurs in Certain Species Only of a Genera. — 

 Striped Larvje do not always feed on or among Grasses.— Occasional 

 Absence of Coloration in Internal-feeding Caterpillar's. — The Eesem- 

 blance of the Larva; of Geometers to Twigs. — Comparative Rarity of 

 Green Tree-frequenting Animals an Argument in favour of Selection. — 

 Deceptively-coloured African Mantis. — Protective Colorationin Spiders. 

 — Do Animals select Resting-places which are in Harmony with 

 their Colour / — Indifferent Colours. — Certain apparently Protectively 

 Coloured Animals probably do not owe their .Coloration to Natui-al 

 Selection. — Specific Characters retained even in Insects which imi- 

 tate the same Environment. — Protection often due to Multiplicity of 

 Surroundings. — Colours of Pelagic Organisms. — Protective Resem- 

 blances due to Causes other than Natiu'al Selection. — Combination 

 of JIany Methods of Defence. — Dimorphism in Coloration. — Variable 

 Protective Resemblances in Chrysalids. — Variable Protective Coloration 

 in Vertebrates. . . ... 83

WARXING COLOUATIOX. 



The Magpie-moth Caterpillar as an Instance of "Warning Colours. — Earlier 

 Experiments with Waruingly-eoloured Insects. — Some Experiments 

 upon the Palatabilily of Various Animals. — Warning Coloui-s can only 

 be safely adopted by a comparatively Small Number of Animals.— 

 Objections to the Current Theory of Warning Coloration. — The 'W'iuo-s 

 of some Inedible Butterflies resist Injury. — Dr. Eisitr's Theory of 

 Warning Colours. — Connection between Integumental Pigment and 

 Excretory Products.— Warning Colours of Nudibranchs.— 'Warninu- 

 Coloration in Wasps.— Dr. Eisig's View not universally applicable.- 

 The Wai-ning Coloration of the Skunk.— Warning Coloration in Other 

 Mammals.— Warning Coloration in Reptiles.— Warning Coloration in 

 Amphibia.— Bright Colours not always used as a ^Varuiug.— Instance 

 of Alluring C!oloration in a Lizard.— Other Examples of Alluring Colours. 

 —Bright Colours and Largo Size of the Eins in certain Fish may Iiave
