 Occasionally captured in our northern waters, and reaching 3 feet in length 



(Castelnau, P.L.S. N.S.W. iii, 1879, p. 372, has recorded a species from 

 Port Jackson, which he doubtfully identified as L. glyphodon Gunther, while 

 Kner, Novara Zool. i, 1865, p. 81, equally doubtfully identified a fish a L. harah 

 Forskal, which was said to have been taken at Sydney. There is no reason to 

 suppose either species occurs in New South Wales).
