FISHES. — MCCULLOCH. 183 



Genus Pelates, Cuvier <fc Valenciennes. 



Pelates (Cuv. & Val.), Ogilbv & McCulloch, Mem. Qld. Mus., 

 v., 1916, p. 125. 



The " Endeavour " collection includes four specimens of 

 P. sexlineatus, Q. & G., and eight of P. quadrilineatus, Bloch. 

 As they were all taken within a hmited area of the Queensland 

 coast, it was thought that they might be merely sexual forms 

 of the one species, but each is represented by both males and 

 females with the testes and ovaries in an advanced stage of 

 development. They therefore bear out the conclusion that 

 the two species are distinct. 



The differences between them may be tabulated as follows : — 



Spinous dorsal with a large black blotch, the longest spine 

 higher than the anterior ray. Usually three dark stripes 

 between the supraorbital margin and the occipital crest. 

 Black shoulder-spot prominent. MaxiUary reaching beyond 

 the vertical of the hinder nostril. quadrilineatus. 



Spinous dorsal without a black blotch, the longest spine and 

 the anterior ray subequal in length. Two dark stripes between 

 the supraorbital margin and the occipital crest. Black 

 shoulder spot indistinct or absent. Maxillary not reaching 

 beyond the vertical of the hinder nostril. sexlineatus. 



Pelates quadrilineatus, Bloch.
