filleted fish (Anonymous 1978). Also trawled in 

 the Gulf of Papua. 



Distribution. — This is the most estuarine of the 

 species of Scomberomorus in Australia. It is 

 confined to estuarine and coastal waters of north- 

 ern Australia from Shark Bay, Western Australia, 

 through the Northern Territory, and Queensland 

 to northern New South Wales (Whitley 1964a:252, 

 fig. 5f; Lewis 1981:17) and southern Papua New 

 Guinea (Fig. 55). Reports of specimens collected by 

 D. G. Stead from Thailand and Malaya (Whitley 

 1964a:252) are based on misidentifications. 



Geographic variation. — Comparisons of morpho- 

 metry characters for three small samples of S. 

 semifasciatus were made with ANCOVA: Queens- 

 land (n = 3-4), Northern Territory (n = 3-5), and 

 New Guinea (n = 13-22). Null hypotheses that the 

 3 sets of regression lines are coincident were 

 accepted for 23 sets, rejected for 3 sets: Base 

 ID, orbit (fleshy), and orbit (bony). The New- 

 man-Keuls Multiple Range Test showed that the 

 Queensland and New Guinea populations differed 

 significantly from each other in Base ID (slopes 

 0.256 and 0.211, Q = 4.392**) and that the New 

 Guinea population differed from the Northern 

 Territory population in fleshy orbit (slopes 0.020 

 and 0.030, Q = 5.492**) and bony orbit (slopes 

 0.034 and 0.046, Q = 7.523**).
