158 ON FISHES NEW TO THE AUSTRALIAN FAUNA. [Mar. 19, 
Eye large, four thirteenths of the length of the head. 
Maxilla reaches beyond the anterior margin of the orbit. 
3. Platystethus huttonii’. D. 13/36. A.3/32. L.1.90. Eye 
moderate, two ninths of the length of the head. Maxilla 
not extending to the front margin of the orbit *. 
Cua@rops omMopTerRvs (Rich.). 
During the month of June 1888, I obtained in the Sydney 
market three adult examples of a Cherops which I believe to be 
identical with Sir John Richardson’s C. ommopterus ; but on account 
of certain constant differences in the pattern of coloration, I append 
a description of the life-colours, all three examples being exactly 
similar in this respect. They were of Jarge size, measuring respec- 
tively nineteen, twenty, and twenty-four inches, and came from the 
Clarence River, New South Wales, this being the first recorded 
instance of the occurrence of the species within the colony, and 
extending its range southward by many degrees. ‘The only difference, 
besides the coloration, between Dr. Giinther’s description and my 
specimens is that in the latter there are in two but nine, and in the 
third ten scales, in an oblique row beneath the lateral line. The 
colours of the fresb fish are as follows :—upper part of head green, 
becoming gradually more tinged with blue towards the snout; 
cheeks and opercles olive ; mandibular region pale violet ; chin sky- 
blue; edge of the maxillary lip with a narrow outer golden and inner 
blue stripe ; anterior margin of the preorbital very narrowly edged with 
blue ; an oval sky-blue spot in front of the orbit, and extending to 
about one third of its diameter. Body olive-brown above the lateral 
line, rose-coloured below, most of the scales on the back and caudal 
peduncle with a medium-sized, round, blue spot ; a broad dark band 
runs from the fifth scale of the lateral line forwards and downwards 
in an arcuate shape to the inferior margin of the opercle. Dorsal 
fin golden, the spinous portion with a basal, median, and marginal 
band of blue, the two outer of which are exchanged on the rays for 
wavy, anastomosing lines of the same shade; anal fin grey, with a 
broad basal and marginal blue band, bordered on the inner edge by 
a narrower golden stripe ; ventrals bluish, the membrane between 
the first and second rays golden ; pectorals grey, with two transverse 
golden bands in front of the base, and the two outer rays and basal 
third of the others blue; caudal brownish, with the outer rays blue, 
and the bases of the remainder green. Irides golden and crimson, 
with sky-blue marginal spots. 
Count Castlenau’s Torresia australis, of which the type is unfor- 
tunately missing, is probably the young of Cherops ommopterus. 
P.S. (Dec. 22, 1888).—Since writing the above I have received 
another large specimen from the same locality, which agrees exactly 
in coloration with those here described. 
1 From Dr. Giinther’s description (Ann. Nat. Hist. [4] xvii. 1876, p. 895) it 
appears to me that this fish has quite as good a claim to separate generic rank 
as many other Carangoids the right of which has never been questioned.

pl. xi. f. 31 ©), is a Cyttus. :
