MEMOIRS OF THE QUEENSLAND MUSEUM. 
case Triurm Lacepede replaces Ranzania Nardo and T. bougainvilleanns becomes 
the name for the Indian Ocean form if that be really distinct from Ostracion laevis 
Pennant 1776. 
In confirmation, I have just received from Dr. E. \V. Gudger of New York, the following 
note {'hi lit., April 1.5, 1937) : — 
“ When your letter of March 15 came yesterday I at once got a copy of Lacepede, 1847 
edition, and looked up Triurus hou^ainvilleanus. First of all, it is interesting to see that Commerson 
got these from the stomach of mackerels. Gn yesterday I sent you a copy of “ The Tail of 
Masturus ” [Ann. Mag. Nat. Hist. (10) xix, 1937] and in it you will find that a considerable number 
of small specimens have come from the stomachs of kinghsh and dolphins. When I worked through 
Lac()pedo’a text .... I felt all the time that he was talking about a young Ranzania, so that 
unconsciously I have come to the same conclusion about Triurm that you did. It is to be regretted 
that he did not give sizes, and particularly that ho did not state that the tail is obliquely cut down- 
ward and forw'ard. Had he done .so there would have been no shadow of doubt as to what the 
fish is. I strongly think it is Ranzania." 
Dr. Gudger enclosed a photograph of a Sunfish from Rottnest Island, near Fremantle, 
Western Australia, dated 30/8/36. This appears to represent Masturua lanceolatus (Lienard, 1840), 
and shows that we now have all three genera of Sunfishes {Mola, MaMurus, and Triurus) in 
Australian waters.
