ANALYTICAL INDEX 



NAMES of quoted books, memoirs, journals, and publications of learned 

 societies are printed in thick (Clarendon) type, and the latter are indexed 

 under the name of the society. 



The substance of the titles of the text is printed in small capitals, and is 

 followed by the word 'introduction', or 'essay', with its number. The sub- 

 stance of the sectional headings of the text is followed by the contraction 

 ' introd.', or the number, omitting the word ' essay '. 



Quoted titles, beginning with the same word as titles or headings of the text, 

 precede these latter, and are themselves arranged in the alphabetical order 

 of the second word. Titles, &c, of the text, beginning with the same word, 

 are not thus arranged, but are placed in the order of pagination before the 

 list of references under the same word. 



References under one word are generally given in the order of pagination. 

 In certain cases, however, they are grouped more or less completely accord- 

 ing to subject. 



Footnotes, containing references only, are rarely indexed. 



Species are indexed under generic as well as specific names, but the 

 analysis of text is given under the specific name alone. The generic name is 

 distinguished by a capital initial letter. 



Popular terms with a definite connotation such as ' beetles ', ' butterflies ', 

 ' caterpillars ', and ' weevils ', are fully indexed, in preference to their more 

 technical equivalents ' Coleoptera', ' Rhopalocera ', ' Lepidopterous larvae', 

 and ' Curculionidae ', respectively. When the connotation is less definite, 

 e.g. in 'flies' and 'bugs', full references are given under the scientific 



equivalents, ' Diptera' and ' Hemiptera' respectively. 



'f.' indicates 'form'; 'sub-sp.' indicates 'sub-species'; 

 'species.'
