This unique Australian example belongs to the col- 
lection of the South Australian Museum at Adelaide, and 
is labelled as having been collected in Edcombe ( ? Edge- 
combe) Bay, Queensland. It formed one of a collection 
of catfishes and eels kindly forwarded to me for examin- 
ation some years ago by the Trustees of that Museum, to 
whom I take this opportunity of again returning my grate- 
ful thanks. 
I have gone very fully into the history of this well 
known Indian fish for two sufficient reasons ;—firstly, 
because this is the earliest record of its occurence in Aus- 
tralian waters, and indeed, so far as I am aware, in any 
waters east of Burmah, no mention being made of it as a 
Malayan fish by either Cantor or Bleeker. I have, how- 
ever, no reason to doubt that the locality given above is 
correct, even though its presence in the intermediate area 
has escaped the detection of such keen observers as the two 
biologists referred to as well as of all our Australian col- 
lectors ; and secondly, because I do not know any detailed 
diagnosis of the family Amphipnoide. Though the genus 
Amphipnous has been included in the Symbranchide, 
(though separated as a subfamily, Amphipnoina) by 
Giinther, Day, and others, the presence of scales and of a 
lung-like accessory branchial organ, and the degradation 
of the osseous attachment between the shoulder-girdle
