OF AUSTRALIA. 149 
three-fourths of that between the mouth and the end of the 
snout ; no spines on the eyes nor shoulders ; a median line 
of strong, compressed, arched spines, placed far apart 
one from the other • the rostral ridges are arched inwardly, 
and on their anterior part they are only separated by a narrow 
groove ; the two dorsals large, as long as the interocular space ; 
the dorsal tubercules very feeble between these fins, and not 
visible at all behind the second. The upper surface is rough, 
and the back is covered with small rough tubercules. The 
upper surface is entirely of a light brown, with the snout of 
the same colour. The lower surface is of a light yellowish 
white. 
The specimen is over fourteen inches long. 
Nota. This sort appears to have a shorter, broader, and 
more rounded snout than any other of the genus ■ the 
distance from the posterior angle of the pectorals to the 
extremity of the snout, is very little superior to the breadth 
of the fish. It is named in honour of my late friend, August 
Dumeril. °
