020 THE AUSTRALIAN HYDROMEDUSiE, 



STATISTICS OF THE AUSTRALIAN HYDRO-MEDUSAE. 



In the following table I have enumerated all the known Aus- 

 tralian species. 



I comprise within the Australian area the South Coast of New 

 Guinea, Fiji, New Zealand, Australia and Tasmania, and the 

 Islands South-west of Fiji. 



The total number of species is 231, which are distributed among 

 69 genera. 



Hydi'opolypinae 176 



Hydromedusinpe 40 



Hydrocorallina? 11 



TrachomedusinsD 4 



This list is an extract from the five papers on the subject pub- 

 lished in these proceedings. Besides the older authors, De Lamarck, 

 Lamouroux, M. Edwards, Busk, and others who described some 

 Australian species, we are mainly indebted to W. Thompson, 

 Coughtrey, Bale, Kirchenpauer and Haeckel for our present 

 knowledge of the species. 



The number of species which I have described for the first time 

 is 30. The table is arranged according to the system expounded in 

 the introduction of this Monograph.
