GEOGRAPHIC DISTRIBUTION OF SPECIES. 



The following table shows the geographic distribution of the species de- 

 scribed in this memoir. There is a column each for the collections made at 

 Cocos-Keeling by Dr. Wood Jones, at Murray Island by Dr. Mayer, and at 

 Fanning Island by Mr. Carl Elschner. In the last column the distribu- 

 tion especially in other areas is indicated. By comparing the four columns 

 it will be seen that a number of the species, although not collected at Murray 

 Island, probably occur in the Great Barrier Reef area, for they have been 

 found west of it in the Indian Ocean and east of it in the Pacific Ocean. It 

 is therefore probable that, with few exceptions, all the species described in 

 this paper are to be found in the Great Barrier Reef area. 



The total known fauna of the Great Barrier Reef may be compiled by 

 taking the list for Murray Island and supplementing it by the names of 

 species given under Astreopora, Turbinaria, Montipora, and Acropora. To 

 these names should be added those contained in Quelch's report on the 

 Challenger corals, unless already included. The list published by Saville- 

 Kent is of very little value, as it is to a considerable degree only a hetero- 

 geneous assemblage of names, many of which do not apply to any Australian 

 corals. A complete list of the Australian coral faunas, as at present known, 

 is not here published, for reasons already stated.
