NOTES ON FISHES FROil 'WESTERN AUSTRALIA — WAITE 211 



we have received the following species : — 



GoNORHYNCHUS GREYi, Richardson. 



Tylosurus ferox, Giinlher. 



I am not aware thac this species has been previously recorded 

 from West Australia. Castelnau has described a species under 

 the name Belone gavialoides,* which, judging from the description, 

 and taking into account the relative position of the tins, is distinct 

 from T. ferox. 



Trachurus declivis, Jenyns. 



CoLPOGNATHUS DENTEX, Cuvier and Valenciennes. 



Giinther's type of C. richardsoniij regai'ded by Boulenger; as 

 synonymous with C. dentex, was obtained at Freemantle, at the 

 mouth of the Swan River, wherein Mr. Woodward's specimens 

 were taken. Our examples are without markings of any descrip- 

 tion, and this fact, taken in conjunction with the widely different 

 colouration or ornamentation of the tigures of Quoy and Gainmrd,§ 

 Richardson, II and Giinther,11 indicates that the species is sulr>ject 

 to great variation in colour and pattern. 



Chrysophrys DAtNiA, Forsk. 



Although tliis species does not appear to have been previously 

 noticed from Western Australia, it was naturally expected that, 

 having such an extensive distribution, it would sooner or later be 

 thence recorded. It may now Ije said to occur on the whole of 

 the eastern, northern, and western seaboards, but being so much 

 more numerous in the tropics, we are scarcely likely to tind more 

 than a straggler or so on our southern shores. 



Odax richardsonii, Gilnther. 



The specimens received do not differ from examples taken in 

 Port Jackson ; the dark markings on the body are very pronounced, 

 and in this the examples are not unlike 0. semifasciatus, Cuv. and 

 Val., from which the species is distinguished by the serrated pre- 

 operculum and by the smaller number of scales above the lateral 

 line — seven in 0. richardsonii, fifteen in 0. semifasciatus. 



The serrations in some specimens are so slight as to be of 

 doubtful specific value, yet Castelnau proposed for examples with 

 serrated preoperculum, the generic name Neodax.
