2 THE VOYAGE OF H.M.S. CHALLENGER. 



greater number of novelties were dredged off Kerguelen and the adjacent islands, the 

 Isopod fauna of which has been hitherto comprised in a very meagre list consisting of 

 only fifteen species ; to this I am able to add fifteen new species. 



In other parts of the world, with the exception of Australia, dredging in shallow- 

 water proved to be not very productive as regards this group. A great number of 

 species, particularly among the Sphaeromidae, were dredged along the southern and 

 eastern shores of Australia, but most of these species prove to be identical with forms 

 already described by Mr. Haswell. I have to acknowledge my indebtedness to Messrs. 

 Chilton, Miers, and G. 0. Sars, for sending me their papers dealing with Isopoda ; also 

 to Professor G. 0. Sars for kindly forwarding to me drawings of Isopoda collected by him 

 off the coasts of Norway, but only as yet briefly described ; to the Rev. T. R. R. 

 Stebbing for the loan of several species described by him, and finally to Mr. G. M. 

 Thomson for a collection of Isopoda from New Zealand, which have proved to be of the 

 greatest assistance in determining several points, which will be referred to in the course 

 of the following pages.
