Land, Fresh- Water, and Marine Crustacea. 131 



The Eev. Canon Norman's papers on " British Land 

 Isopoda " and " British Isopoda Chelifera " [in Ann. and Mag. 

 Nat. Hist. (7), vol. iii. (January and April 1899)] have been 

 useful to me in the preparation of this section of the 

 Catalogue, and to shorten the synonymy the reader is 

 referred to these works ; also to a paper by myself in the 

 Annals of Scottish Natural History for October 1898.
