north-western parts of Arnhem Land, viz. the Victoria, Daly, 

 Mc Kinley, Mary, and South Alligator Rivers and some small 

 ponds as well. As to the geographical situation of ttiese localities, 

 I beg to refer to the adjoining map-sketch (fig. 1), drawn partly 

 from a sketch in Dr. Dahl's popular account of his travels „Dyr 

 og vildmaend" (Christiania 1897—1901). 



The specimens of marine fishes have been obtained chiefly 

 in Roebuck Bay, Kimberley District of North-West Australia. 

 In a previous paper (K. Vet. Ak. Handl., Stockholm 1921), I have 

 had the opportunity of treating a collection of marine fishes from 

 the some locality, and I think, that the data given below may 

 be of some supplementary value. 



Before proceeding to give a systematically arranged review 

 of the species, I wish to make some general remarks about the 

 present material from a more zoo-geographical point of view. 



The marine fishes. 



Among the marine fishes in the present collection, there are 

 three species, which are new to science, viz. Craterocephalus 

 capreoli, Rhinoplagusia australis, and Pseudohatrachus dahli, 

 all collected in the Roebuck Bay. 



Of the other species, the main part belongs to widely distri- 

 buted Indo-Pacific or Indo-Australian forms: 



Species Distribution 



Arius thalassinus .... Red Sea to east coast of Au- 

 stralia. 



Pristipoma hasta .... Red Sea to Australia. 



Chrysophrys hasta .... East Indies to Australia. 



Drepane punctata .... East coast of Africa to Austra- 



ha, northwards to China. 



Scatophagus argus .... Ceylon and India to Tahiti, north- 

 wards to China. 



Chorinemus lysan .... Red Sea to western Pacific.
