The length of the head is three times and a-half in the total 

 length (without caudal) ; its upper surface is flat and impressed 

 with two large radiated impressions, an elongated space in front 

 of the eyes covered with small scales ; a longitudinal groove on 

 the medial line of the snout. Teeth very fine and numerous, with 

 a line of large, conical, distant ones on each of Loth jaws, getting 

 smaller and closer behind ; no vomerine teeth ; tongue smooth. 

 The diameter of the eye is half the width of the interorbital space. 

 Body rather compressed ; its height is Jess than the length of the 

 pectorals. Caudal fin strongly emarginate, the lower lobe longer 

 than the upper. Colour in spirits dark brown above, silvery 

 bpneath. ; the snout black ; the fins yellow. 



West Australia. Length from three to four feet.

The length of the head is one-fourth of the total length (with- 

 out caudal) ; its upper surface is striated, with a broad moderately 

 deep groove in the centre ; the beak is striated above ; the prse- 

 orbital entirely covers the maxillary. The diameter of the eye is 

 about equal to the width of the interorbital space, and one-third 

 of the length of the postorbital portion of the head. The length 

 of the pectoral fin is much greater than the height of the body, 

 but much less than the distance between the opercular margin 

 and the eye. The ventral fin is situated nearer to the eye than to 

 the root of the caudal. The anal fin commences much in advance 

 of the dorsal, but both terminate near and at an equal distance 

 from the caudal ; the hinder rays of both are short and well 

 apart. The caudal is long and rather acutely rounded ; the free 

 poation of the tail is much flattened above, and roundly keeled
