Family NEMIPTERIDyE. 



Genus Nemipterus, Swainson. 



Sub-genus Euthyopteroma, Fowler. 



Nemipterus (Euthyopteroma) aurifilum, Ogilhy. 



Yellowlif. 



Pentapus aurifilum, Ogilby, New Fish. Qld. Coast, 1910, 

 p. 93, and Mem. Qld.'Mus., v., 1916, p. 161, pi. xx. 



This species is not a Pentapus but a Nemipterus, as I have 

 been recently informed by Mr. Ogilby. It evidently enters the 

 subgenus Euthyopteroma, and is closely allied to E. hathyhium, 

 Snyder^, from which it may be distinguished by its much 

 larger eye. 



Fifty-four specimens, 103-176 mm. long from the snoiit to 

 the end of the middle caudal rays, exhibit very Uttle variation. 

 The caudal filament is present in all, but is much longer in 

 some than in others. Ogilby has described the fifth dorsal 

 spine as the longest, but the succeeding ones usually increase 

 slightly in length to the last. 



Loc. — Thirteen miles south-west of North Reef, Queens-

1908, p. 25. 

 Eleven specimens, 165-224 mm. long, do not differ from 

 examples of about the same size from India and the Philip- 

 pine Islands. Some are almost uniformly spotted, while others 

 have three narrow longitudinal bands formed of enlarged 

 coalescent spots ; the remainder are intermediate between 

 these two forms. 



A larger specimen, 300 mm. long, is evidently the same 

 species, but has lost all traces of colour-marldng on the body,
