64 NEW GENERA AND SPECIES OF AUSTRALIAN FISHES, 



Depth of gape (from angle to base of median teeth).. 212 mm. 



Width of gape (from angle to angle) 160 ,, 



The history of this pair of jaws, which is in the University 

 Museum and is labelled "Cape of Good Hope?" is most unsatis- 

 factory ; briefly, as related to me by Mr. George Masters, the 

 Curator, it amounts to the following : — 



The specimen originally formed part of the old collection made 

 by W. Sharpe Macleay, and it was only after that gentleman's 

 death that the label was attached by order of the late Sir William 

 Macleay, but on what grounds he believed it to come from the 

 Cape Mr. Masters does not know. It is plain, therefore, that the 

 locality given on the label cannot be depended on. 



As the individual from which these jaws were taken is 

 unknown, I cannot be certain as to which of the recent genera of 

 notidanoid sharks the present species properly belongs, but it 

 plainly comes nearest to Hepirancliias in the presence of a strong 

 coronal cusp to the median tooth of the lower jaw, a character 

 which is found only in the Sqnalus cinereus of Gmelin, which is 

 the type of Rafinesque's genus ; in that species, however, the 

 symphysis of the upper jaw is toothless. 



I have much pleasure in dedicating this n(^w and interesting 

 Notidanid to my friend Prof William A. HasweU, whose 

 important paper on the NotorhyncJius imlicus was published in 

 our Proceedings some years ago.
