■"I^HE first Terrestrial Isopoda described from New Zealand were those given by Dana * 

 in 1853, in his account of the Crustacea collected by the United States Exploring 

 Expedition ; in it he described and figured in considerable detail 7 species (includino- 

 one doubtful one), all of them from the northern part of New Zealand. In 1865 one or 

 two species were added by Heller f in the report on the Crustacea of the Novara 

 Expedition. In 1870 Mr. E. J. Miers % comjiiled a Catalogue of the New Zealand 

 Crustacea, and in connection therewith described some new species that were in the 

 collections of the British Museum ; he added 5 species, and his catalogue contains 

 altogether 12 species and one considered doubtful. During subsequent years a few 

 species were added by JVIr. G. M. Thomson § and myself || , and all the species known 

 were included in our " Critical List of the Crustacea Malacostraca of New Zealand." ^ 

 In 1885 Budde-Lvmd ** published his " Crustacea Isopoda Terrestria," and added two 

 new species and mentioned most of those previously described, but as he was unable to 

 examine specimens he could give no additional information on them, and was obliged to 

 leave several of them under the heading of "imcertain sjiecies." Four other new species 

 were described and figured by Eilhol in 1885 in his " Mission de File Campbell," ff in 

 which he also gave references to previously described species. 



In the present paper I endeavour to give a complete list of aU the New Zealand 

 Terrestrial Isopoda at present known, with descriptions of the various species and figures 

 where necessary. The material at my disposal consists chiefly of collections that I have 

 accumulated since 1884. Besides sj)ecimens that I have collected myself, I have 

 many from Mr. R,. Helms, formerly of Greymouth, Mr. J. McMahon, of Kenepuru, 

 Mr. W. W. Smith, of Ashburton, Mr. S. H. Drew, of Waugauui, Mr. H, Suter and 

 Mr. R. M. Laing, of Christchurch, and Mr. L. Hames, of Takapuua. Mr. G. M. 

 Thomson has very kindly placed in my hands the whole of his collection, including
