Variation. — Only the largest examples of this species have the 

 maxilla produced backward towards the pi^eopercnlum as described by 

 Ogilby and figured by McCulloch. A fine series of over one hundred speci- 

 mens, 18-41 mm. long, which were taken togethei- in Port Jackson, shows 

 that the mouth is always small in young specimens, reaching only a little 

 beyond the vertical of the anterior border of the eye ; this last decreases 

 in size considerably with growth, and in the largest specimens of the 

 series, the maxilla extends to below its posteinor third. In a 45 mm. 

 specimen, the end of the maxilla is a little behind the vertical of the 

 posterior orbital border, and in one of 58 mm., it is midway between the 

 eye and the preopercular margin.

The body is more slender in the young, but the characteristic colour- 

 marking is well developed in even the smallest specimens of our series. 



Locs. — Many specimens, including the holotype, are in the Australian 

 Museum from several localities between Newcastle and Jervis Bay, New 

 South Wales.
