RECORDS OF SCANDINAVIAN WOODLICE. 225 



Since Webb and Sillem's ' British Woodlice ' was published 

 in 1906 a small band of workers have added considerably to our 

 knowledge of the distribution of known species, and have made 

 several interesting additions to the fauna, including Tricho- 

 niscus pygmceus, G. 0. Sars (England, Scotland, and Ireland) ; 

 Armadillidium album, Dollfus (Devon) ; Eluma pur pur as c ens, 

 Budde-Lund (Ireland); and four hothouse species new to science, 

 namely, Trichoniscus stebbingi, Patience (Scotland, England, and 

 Belgium), T. spinosus, Patience (Clyde), T. linearis, Patience 

 (London), and Philoscia patiencei, Bagnall (London and Win- 

 laton).
