270 FLEAS, FLUKES AND CUCKOOS 



sometimes given in detail, so that British fauna can be separated from 

 the rest. 



There are several famous series of zoological treatises, such as the 

 Cambridge Natural History, which set out to survey the animal kingdom 

 group by group. It is of the greatest importance to consult the four 

 main series of this type (see below) no matter in which group of para- 

 sites the reader may be interested. Some of the volumes are now quite 

 out of date but others are recent and first class — for example, Strese- 

 mann's Aves (Handbuch der Zoologie, 1934). 



For the study of every group of parasites it is of course useful to find 

 an up-to-date and reliable textbook, particularly one which supphes a 

 good, but not necessarily detailed, classification of the group concerned. 

 In many cases no such book exists and the unfortunate non-specialist is 

 then left to flounder. Below, the authors have endeavoured to suggest, 

 chapter by chapter, what literature will prove helpful if the reader 

 wishes to embark on a more serious study of the parasites in question. 

 (Unless otherwise stated the papers are written in English.) Some of the 

 publications have been suggested partly on account of their valuable 

 bibliographies, and these have been marked with an asterisk. 



Throughout the text the reader will find an occasional reference to 

 an author or to a paper which does not appear in the relevant list in the 

 Bibliographical Appendix. However, the full reference to these authors 

 and their publications will be found in the papers indicated by an 

 asterisk. Thus, for Chapter 7, references to the numerous works of 

 Jordan and Rothschild will all be found in Pulgas by A. M. da Costa 

 Lima and C. R. Hathaway, A Synopsis of the British Siphonaptera by 

 N. C. Rothschild or Katalog der palaearktischen Aphanipteren by J. Wagner, 

 which contain copious bibliographies. 



Most of the literary quotations in the text are so well known that it 

 seems unnecessary to refer to their source. The particular translations 

 of Pliny and Mouffet from which we have quoted so liberally are, how- 

 ever, especially attractive, and these references are consequently given 

 below. 



Holland, Philemon (1601). The Historie of the World commonly called the 

 Naturall Historie of C. Plinius Secundus. Trans. P. Holland.

 The History of Four footed Beasts and Serpents. Edited by John Rowland.
