The typical specimen of S. altipinnis is in the Australian 

 Museum collection ; it is stuffed and in very poor condition, 

 but such of its characters as are retained indicate that it is 

 the adult form of the species described and figured by Regan 

 as S. pleurogramma. A series of specimens of different sizes 

 shows that the colour-markings change with growth, larger 

 examples losing the dark lateral band and the cheek-markings 

 which are characteristic of younger specimens. According to 

 Ogilby's description, the type had no lateral fold on the tail, 

 but this appears to be incorrect. 



Waite recorded these adult and young forms from Lord 

 Howe Island as S. oblongus, Bloch, and S. hypselogeneion, 

 Bleeker : but the species bears little resemblance to the 

 former, while according to Regan it also differs from the 

 latter. 



Loc. — The Australian Museum includes specimens from 

 near Sydney, New South Wales: Moreton Bay, Queensland; 

 and Lord Howe Island. The South Australian Museum 

 possesses an example taken by Mr. Lea at Norfolk Island.
