 SUMMARY AND CLASSIFICATION 



It now remains to bring together the results arrived 

 at, and to show their relation to one another, in a 

 system of classification. 



I have not introduced the terms proposed below 

 into the earlier parts of this book : it appeared better 

 first to illustrate the meaning and use of existing 

 terms by the description of numerous instances. I 

 trust, however, that the new terms may be found to 

 be useful. My friend Mr. Arthur Sidgwick has kindly 

 helped me in choosing the words. 



In the following scheme Protective and Aggressive 

 Kesemblances are grouped with Mimicry under the 

 fi^rst h^ad of Apatetic Colours, because an animal is 

 thus made to resemble some other species or some 

 other object. Protective and Aggressive Eesemblances 

 are classed as Cryptic Colours (Procryptic and Anti- 

 cryptic), because their object is to effect conceal- 

 ment ; Mimetic Eesemblance and Alluring Colouration 

 are called Pseudosematic Colours, because they 

 usually resemble Sematic or Warning and Signalling
