This species is distinguished from A. affinis and A. 

 lineatus by its small number of scales on the lateral line, 

 different fin formulae and by its short and deep form. 



Trawled in 37 fathoms off Flinders Island, Investigator

This species is extremely variable with age, the young 

 being short bodied and round, and the depth only 2| in the 

 total length, while large specimens are much more elongate 

 with the depth 3J. The form and armature of the bones of the 

 head is essentially the same in both, but those of the young 

 have much more spinate edges, and their surfaces are smooth 

 and with but few ridges. The same remarks applv to the 



no. 11. 



scales which have very coarsely denticulated edges and almost 

 smooth surfaces ; in the adult the denticulations are much 

 finer and they are continued back as ridges almost half way 

 across the exposed portions of the scales. The accompanying 

 figure represents my smallest specimen (70 mm. long).
