ENUMEBATION OF ANIMALS. 



ENUMERATION OF THE ANIMALS WHOSE CHARACTER AND 

 HABITS FORM THE BASIS OF THE AUTHOR'S GENERAL- 

 ISATIONS. 



The following catalogue is the result of the conviction that it is 

 desirable to show the exact nature, variety and extent of the bases 

 on which the generalisations contained in the body of this work are 

 founded. In general terms and in round numbers it may safely 

 be affirmed that the conclusions referred to have been based on the 

 character and habits of about 1,250 animal species, representing 

 though necessarily unequally all zoological classes and orders, from 

 the Protozoa up to the Quadrumana. Of these species I have been 

 able seriatim to catalogue only 930 ; while, in the case of at least 300 

 others, the species, for various reasons immediately hereinafter to 

 be described or explained, have been indeterminable. Of the 300 in- 

 determinable species about 100 are birds, another 100 insects, while 

 the third hundred are mammals, fish, or other animals. 



. The appended catalogue has involved an immense amount of 

 labour incommensurate, perhaps, with the result ; much of it 

 fruitless, unrepresented and unrepresentable. I can honestly 

 affirm, indeed, that the compilation of this section of the Appendix 

 has cost me infinitely more trouble comparatively than the other 

 investigations on which the body of this book has been based; 

 while, notwithstanding all the pains bestowed, it cannot be con- 

 sidered accurate, complete or satisfactory. 



The catalogue makes no pretence to be regarded as exhaustive 

 or even precise. I had no sooner begun to draw it up in the form 

 in which it appeared desirable to present it to the general reader, 

 than I found insuperable difficulties in rendering it at all complete, 

 on the one hand, or accurate on the other. As a warning to future
