7. Apogon aterrimus, sp. N. 
D.7[>- A.>. L. lat. 25. 
The height of the body is one-third of the total length (with- 
out caudal). Entirely uniform deep black. 
Cape York. 
8. Apogon Nove Hollandie (Val.). 
New South Wales. 
9. Arripis georgianus (C. & V.). 
Port Jackson, Hobson’s Bay, Holdfast Bay, Houtman’s 
Abrolhos. 
10. Therapon percoides (Gthr.). 
Fitzroy River, Nicol Bay. 
The cross bands become less distinct in large examples, of 
7 inches in length. 
11. Therapon unicolor (Gthr.).

14. Scatophagus argus (L.). 
- = Sc. ornatus (C. & V.). 
In young specimens the markings are frequently like those 
represented in Sc. ornatus by Cuvier and Valenciennes; but 
these specimens do not constitute a distinct species, being in other .

on the head. The length of the dorsal spines is subject to much 
variation. Young specimens from Australia exhibit the coloration 
of Sc. ornatus; adult do not differ from Kast-Indian Se. argus.
