198 ANIMAL ECOLOGY 



Section 3. — Works on particular groups of British Animals 



The system upon which the works Hsted below have been 

 chosen is explained in Chapter IL When it is stated that no suit- 

 able work exists on any particular group, this does not imply that 

 no good systematic work has been published on that group, only 

 that it is not to be found in EngHsh, or that it is inaccessible, or in 

 a very scattered form, or else not sufficiently up to date to be very 

 reliable. In almost all cases, except very recent publications, 

 there has been published a good deal of additional work in various 

 periodicals, and often much work has been done but has not yet 

 been published by the systematists concerned. The list is neither 

 logical nor complete, but in spite of this, should be found useful 

 to working ecologists. 



Mammals 



Barrett-Hamilton, G. E. H., and Hinton, M. A. C. (1910-1921). A 

 history of British Mammals. London. 



Birds 



WiTHERBY, H. F., and others (1920). A practical handbook of British 



Birds. London. 

 Howard, H. E. (1907-1914). The British Warblers. London. 



Reptiles 



Leighton, G. R. (1901). The life-history of British Serpents. Edinburgh- 

 (1903). The life-history of British Lizards. Edinburgh. 



Fish 

 Maxwell, H. (1920 circ). British freshwater Fishes. London. 



Molluscs 



Ellis, A. E. (1926). British Snails. Oxford. 



This book covers the gasteropods of land and fresh water. There 

 is no convenient and accurate work on the freshwater lamellibranchs, 

 and the systematic position of a good many of the species is still in 

 dispute. 



Crustacea 



Webb, W. M., and Sillem, C. (1906). The British Woodlice. London. 



There is no comprehensive work upon the freshwater Crustacea 

 of the British Isles, but much information can be obtained from Ward 

 and Whipple's " Freshwater Biology," ®' which although dealing with 

 American forms, is most useful, since many of the genera, and in the 

 case of smaller forms, species, are the same in Europe and America. 

 The following other works may be mentioned : 



Tattersall, W. (1920). The occurrence of Asellus meridianus Rac. in 

 Derbyshire. Lanes, and Cheshire Naturalist, May, p. 273 (contains 

 key to species of Asellus). 



Bars, G. O. (1895). An account of the Crustacea of Norway, Christiania 

 and Copenhagen. Vol. i. (Includes an account of the genus 

 Gammarus^
