GALEID^. 

 RHIZOPRION gen. nov. 



Teeth in the jaws similar, oblique, with a smooth median cusp and serrated 

 outer base. ( 'pi£a, root ; irplcov, saw. ) 



Type: — Caroharias (Scoliodon) crenidens Klnnzinger. 17 



This is the most common of all the smaller galeids on our coast, and has 

 the right of inclusion in the New South Wales fauna, the ' ' Endeavour ' ' having 

 trawled a specimen off Cape Byron. It is very distinct from Scoliodon acutus, is 

 in the synonymy of which Garman has placed it. 



CARCHARHINUS AMBLYRHYNCHOS (Bleeker). 19 



I have much pleasure in adding this rare shark to the Queensland fauna, 

 Dr. Hamlyn-Harris having collected a specimen at Cape Bowling-green, N.Q. 

 It is a young female and measures 605 millim. 



PMSTIDyE. 



PRISTIS MICRODON Latham.^ 



Two rostra from Moreton Bay in the Queensland Museum belong to this 

 species as described by Garman. 21 As far as these specimens are concerned it is 

 much to be regretted that Ave have to use Latham's name, for they are without 

 exception the most murderous weapons of the sort that I have yet seen ; of 

 exceptionally heavy build, and bearing enormously long, strong, and trenchant 

 teeth, they are the very antithesis of the more slender and graceful rostrum of 

 P. zysron. 22 These are the pair recorded by me 23 some time ago as P. zephyr ens, 2i 

 a species which Garman makes synonymous with P. microdon. 



RHIXOBATID.E. 



RHINOBATUS ARMATUS Gray.- 5 



An examination of several specimens of the common " shovelnose shark" 

 of the Moreton Bay fishermen shows that the East Australian species is B. 

 armatus Gray not B. granulatus Cuvier 26 as has been supposed. The two
