MCCULLOCH. 73 



The name Trochocopus unicolor Gunther, A.M.N.H. (4) xvii, 1876, p. 398, 

 was based upon a stuffed skin from Port Jackson, which is probably not distinct 

 from the Blue Groper. 



Heterochoerops viridis Steindachner, Sitzb. Akad. Wiss. Wien liii, 1866, p. 

 461, pi. 5, 3, is evidently the very young form of Achoerodus, in which the pre- 

 opercular margin is strongly serrated, and the tubes of the lateral line are simple 

 instead of arborescent.

N.S. Wales, 1893, p. 134. 

 This is probably only a colour variation of the preceding species.

f body. bellis (267b).

Probably only a colour variety of the preceding species. 



CXX. Family Neoodacidae. 



A. Cheeks scaly. Neoodax (26S) . 



AA. Cheeks naked. 



B. Dorsal originating above operculum; scales about 30. Hcieroscarus (269) 

 BB. Dorsal originating above pectoral; scales about 50. Olisthops (270). 



268. Neoodax Castelnau, Res. Fish. Austr. (Viet. Offic. Rec. Philad. Exhib), 



1875, p. 37 (waterhousii) . 

 The status of the older name Odaj-, which has been allotted to three different 

 genera by Lacepede, Cuvier, and Cuvier and Valenciennes, is so uncertain that 

 it seems to be preferable to use Castelnau's name. 



A. About 60 scales on the lateral line. semifasciatus (268a). 



AA. 30-45 scales on the lateral line. 



B. Lateral line about 40- batteatus (268b). 



BB. Lateral line about 45. obscurus (268c). 



268a. N. semifasciatus. Rock Whiting. Odax semifasciatus Cuv. & 



Val., H. N. Poiss. xiv, 1839, p. 299, pi. 407. Odax richardsonii Gunther,

p. 159, pi. 55 (PI. xxxi.). 



Common along the southern portion of the coast, and reaching a length of 



14 inches. There seems to be nothing to distinguish N. richardsonii from N. 



semifasciatus.
