This species was never taken in the trawl, but examples were 

 secured by means of the line. It is not found northward of our 

 Colony, but what its northern limit may be appears to be unknown. 



I am, indeed, not certain that it has been previously recorded 

 from, although doubtless taken off Schnapper Rock, between the 

 Manning River and Cape Hawke, where we hooked several 

 specimens.

Station 32. 



This species was first made known from Manly, immediately 

 north of Port Jackson, on March 22nd, 1881, since which date 

 it had not been met with, until the 6th March, 1898, when we 

 trawled a second individual in 10-12 fathoms, between Cape 

 Hawke and Charlotte Head. 



Having the type specimen also before me, I am able to compare 

 the two, and find, apart from size, onl}^ the following differences : — 

 In Ramsay's example, which is immature, the profile of the head 

 slopes backwards, and the lower pair of canine teeth is developed 

 equally with the upper, the second spine is quite detached from 

 the third, but a glass reveals indication of a ruptured membrane 

 between them.
