STUDIES IN AUSI'IJALIAN FISHES McCULLOCH. 177 



Colour. — Dark slatej'-brown above, gradually changing to leaden-silver 

 below. Head brown above, leaden-silver on the sides. Vertical tins 

 similar to the body ; outer sides of the veutrals and pectorals lighter. 



Described and figured from a specimen 740 mm. long from the snout 

 to the end of tlie middle caudal rays. It differs from Ogilby's description 

 in several characters, but a comparison of it with the holotype of the 

 species, which is stuffed in the Australian Museum collection, shows it to 

 be similar in all details. 



Loc. — This specimen was found washed up on a beach at the entrance 

 to Crookhaven, New South Wales. It was slightly damaged, parts of the 

 eye and caudal peduncle having been eaten awaj', but was otherwise in 

 splendid condition. The specimen was presented to the Trustees of the 

 Australian Museum by the Fisheries Department of New South Wales. 



No species of the genus Centrolophus has hitherto been recognised 

 from Australian waters.

 1904, p. 156, fig. 16. 



Erosa iridea, Ogilby, New Fish. Qld. Coast, 1910, p. 113. 



Having compared the type of E. iridea, which is 80 mm. long, with a 

 small Japanese example of E. erosa, 46 mm. long, I find no differences 

 other than small details of the cephalic structure, which are evidently due 

 to the very different sizes of the specimens. 



Loc. — Nineteen miles N. 30° W. from Double Island Point, Queensland ; 

 33 fathoms.
