THE BRITISH TERRESTRIAL ISOPODA in 



A CHECK-LIST OF THE BRITISH TERRESTRIAL 

 ISOPODA (WOODLICE). 



By Walter E. Collinge, D.Sc, F.L.S., Carnegie Fellow, and 

 Research Fellow of the University of St Andrews. 



Comparatively little attention has been paid to the Wood- 

 lice or Terrestrial Isopoda of the British Isles. During the 

 last few years, however, an increased interest has been 

 evidenced which has led to the desire, on the part of many 

 workers, for a check-list, and believing that such a list will 

 prove useful I have undertaken the compilation of one that 

 will show at a glance the name and authority for each 

 species and variety, the source of the original description, 

 and the distribution in the British Isles. In all, thirty-six 

 species and thirty-five varieties are listed. 



The capital letters following the abbreviation " Dist." 

 after each species and variety represent: E. = England; 

 S. = Scotland ; W. = Wales ; I. = Ireland; and Ch.I. = Channel 

 Islands. 



The species are numbered consecutively and the varieties 

 are lettered. Synonyms are without numbers or letters. 

 Doubtful species and varieties are printed in italics.
