McCULLOCH AND WAITE — FiSHKS FROM SoUTH AUSTRALIA 



55 



margin subcutaneous, operculum unarmed, its lobe with a cleft : gill-membranes 

 forming a free fold across the isthmus : large teeth, forming bands on the jaws, 

 and similar teeth on the vomer; palatines toothless. 



Dorsal composed almost entirely of spines, anal with two spines and numer- 

 ous rays ; 1)oth fins united with the caudal : pectorals present, united with the 

 opercular lobe by membrane: \entrals jugular, with a hidden spine and two rays: 

 \iviparous. 



This definition is based on nine specimens herein ascribed to four species. 

 According to Castelnau, the genotype, O. antarcticits. has palatine teeth, Ijut this 

 is probably an error. 



Synonviiiv. In assuming Nco(jiiiirlliis to lie synonymous with OpIiicHiins, 

 we rely principally upon the evidence afiorded by a specimen in the Australian 

 Museum which is believed to be A', siilcatiis (see notes under that species): 

 Castelnau's description of A^ sulcatns is partly unintelligible, and is contradictory 

 in several details, so that we feel justified in disregarding some of the statements 

 which conflict with our conclusions.
