NOTES ON THE DISTRIBUTION OF SOME AUSTRA- 

 LIAN SHARKS AND RAYS, WITH A DESCRIPTION 

 OF RHINOBATUS BOUGAINVILLE I, Miill. and Henle. 



By J. Douglas-Ogilby, 

 Senior Assistant Zoologist, Australian Museum. 



Having had occasion lately to overlook the collection of Sharks 

 and Rays in the Australian Museum, I have thought that the 

 following notes may ])rove of interest to ichthyologists, especially 

 to those who have made a study of our palseichthyan forms. It 

 will be seen, that in two instances, [those of Scyllium maculatum 

 and Rhinohatus granulatus] I differ in my identification from 

 those who have preceded me in this branch, and from the exami- 

 nation of numerous specimens, both in the Australian Museum 

 and in that of the Hon. Wm. Macleay, I am convinced that 

 neither of these species occur so far south as the New South 

 Wales coast, where their place is taken by my recently described 

 Scyllium anale, and by Miiller and Henle's Rhinohatus bougain- 

 villei, of which latter the habitat was previously unknown, I 

 have also the pleasure in this paper of adding two new genera to 

 the Australian fauna, viz., Rhynchohatus djeddensis, Forsk., which 

 appears to be not uncommon, but has hitherto been mixed up 

 with Rkinobatus ; and Pieroplaiea of which I came across a fine 

 specimen caught near Cape Hawke, by Mr. J. Brown, and which 

 is as yet undescribed. The addition of Tceniura lynima is also 

 worthy of notice, though its previous discovery, on the south 

 coast of New Guinea rendered its Australian record a mere 

 matter of time ; our specimen is from Cape York, and was 

 collected by Mr. Walter Powell.
