The third to sixth dorsal spines are the longest, half as long as 
the head ; the second anal spine longer and stronger than the third.

Moreton Bay. 
Description.—This species is similar to Centropogon australis, 
from which it will be readily distinguished by the shorter third dorsal 
spine, which in C. australis is two-thirds as long as the head. The 
height of the body is contained thrice and a half in the total length ; 
the length of the head thrice and a quarter. Head slightly com- 
pressed, with deep grooves along the interorbital space, which is 
concave and much narrower than the orbit; there is a slight groove 
behind the orbits, across the occiput. Snout shorter than the eye,
