464 ON SOME AUSTRALIAN SHARKS AND RAYS, 



Carcharias crenidens. Klunz. 



Some months ago I received from Mr. Henry Smithurst a small 

 specimen of this shark which had been taken by hook at the 

 Burnett River Heads ; it is barely 12 inches long, yet shows no 

 sign of the umbilical sac, and I conclude therefore that this 

 species never attains a large size. I doubt the possibility of its 

 specific separation from C. acutus, Riipp., with which I had 

 previously identified the small example in question. 



ScYLLiUM anale. Ogilby. 



This species seems to be common in the neighbourhood of Port 

 Jackson, but has been confounded with S. maculatum, Bl., from 

 which it may at once be distinguished by the separation of the 

 nasal valves. I have examined about a score of examples up to 

 this time, but have not found a single specimen of Bloch's species 

 which must, I think, be excluded from the New South Wales list. 



Chiloscyllium ocellatum, (Gmel). 



The Australian Museum possesses a specimen of this fish 

 caught in Port Jackson ; it must, therefore, be included in future 

 in the Fauna of this colony. 



Rhinobatus bougainvillei. M. & H. 



Preoral space 1| in the distance, between the tip of the snout 

 and the vent ; snout moderately produced ; interorbital space con- 

 cave, contained five times in the length of snout. Anterior nasal 

 valve continued inwards by a short fold. Rostral ridges narrow.
