FISHES. -MCCULLOCH. 123 



Locs. I am indebted to Dr. Mark C. Lidwill for the large 

 example here figured, which he captured on a rod and line 

 at Port Stephens, New South Wales. The smaller specimen 

 was caught on a hand-line from the " Endeavour " off North 

 Reef, Queensland, on 13th July, 1910. 



SERIOLA SIMPLEX, Ramsay & Ogilby. 

 (Plate xxxvii., fig. 3.) 



Seriola simplex, Ramsay & Ogilby, Proc. Linn. Soc. N.S. 

 Wales, x., 1886, p. 757. 



The only known specimen of this species is the type, of 

 which the origin is unknown though it was supposed to have 

 been taken in Port Jackson. Though at first separated from 

 S. grandis, it was later united with that species by Ogilby 1 , 

 though he gave no reason for his action. The specimen is 

 197 mm. long, and differs considerably in form from my 

 smallest example of S. grandis, 433 mm. ; it is possible that 

 the difference is due to alteration with growth, but until a 

 series of intermediate examples can be examined it is better 

 to regard the two as distinct. 



Genus TRACHURUS. 

 TRACHURUS NOWE-ZELANDI.E, Hutton. 



Cowanyoung. Horse Mackerel. 

 (PI. xxxiv., fig. 3.) 



Trachurus trachurus, Hutton, Fish. N. Zeal., 1872, p. 16, 



pi. iii., fig. 23 (T. novae, zelandice, C. & V., in synonymy : 



not T. trachurus, Linn.). 

 Trachurus trachurus, McCoy, Prodr. Zool. Viet., dec. ii., 



1878, pi. xviii. Id., Johnston, Proc. Roy. Soc. Tasm., 



1882, pp. 85, 119, and 1890, p. 32. 

 Decapterus leptosomus, Stead, Ed. Fish. N.S. Wales, 1908, 



p. 87 (not D. leptosomus, Ogilby). 

 Trachurus declivis, Waite, Mem. Austr. Mus., iv., 1899, 



p. 72. Id., McCulloch, Zool. Res. "Endeavour," i., 



1911, p. 79 (not T. declivis, Jenyns). 



The Cowanyoung of New South Wales fishermen is identical 

 with the Horse Mackerel of Tasmania and New Zealand. It 

 has been confused with the Yellow-tail, Trachurus declivis, 

 Jenyns, but differs from that species in its form, colouration 



1, Ogilby Ed. Fish. N.S.Wales, 1893, p. 82'.
