Types. — Holotype: QM 1.6588; Cape Cleveland, N 

 Queensland, Australia; G. Coates; 463 mm FL; D 

 XVII + 18 + IX; A 20 + IX; P! 23; RGR X 1 + 1 + 4=6. 



Diagnosis. — This species has relatively few large 



spots (larger than the diameter of the eye) on its 

 sides (Fig. 64). In having few gill rakers (3-9), it is 

 superficially similar to S. commerson but differs 

 in lacking an abrupt downward curve in the 

 lateral line under the second dorsal fin and in hav- 

 ing more vertebrae (48 or 49 vs. 42-46). Postero- 

 dorsal spine of hyomandibula large as in S. com- 

 merson and Acanthocybium. Ventral process of 

 angular long, 117-126% of dorsal process, as in 

 S. commerson and Acanthocybium. Intercalar 

 spine well developed as in S. caualla and S. 

 commerson. 



Description. — Lateral line gradually descending 

 to midline on caudal peduncle. Intestine with two 

 folds and three limbs (Fig. 3m). Spines in first 

 dorsal fin 16-18, usually 17 (Table 9); second dorsal 

 fin rays 17-19 (Table 10); dorsal finlets 9-11, usu- 

 ally 9 or 10 (Table 10); anal fin rays 16-20, usually 

 19 (Table 11); anal finlets 9-11, usually 10 (Table 

 11); pectoral fin rays 21-23, rarely 25 (Table 12). 

 Precaudal vertebrae 19 or 20, usually 20 (Table 6); 

 caudal vertebrae 28 or 29, usually 28 (Table 7); 

 total vertebrae 48 or 49, usually 48 (Table 8). Gill 

 rakers on first arch (0-2)+ (3-8) = 3-9, usually 

 1 + (5-6)= 6-7 (Table 5). Morphometric characters 

 given in Table 25. 



Size. — Maximum size 100 cm FL, 8 kg in weight, 

 commonly 50-80 cm (Lewis 1981). 



Color pattern. — In his original description of the 

 species, Munro (1943) provided a good description 

 of freshly caught specimens from Queensland. 

 Cranial regions and upper part of back iridescent 

 bluish green, cheeks and belly silvery white. In 

 adult fish, sides marked with about three indefi- 

 nite rows of indistinct bronze-grey blotches, each a 

 little larger than orbit. Membrane of first dorsal 

 fin jet black with large contrasting areas of
