The more elongate form, the smaller and more numerous 

 scales, and the long and more deeply forked caudal are 

 features by which this species may be readily recognized from 

 either T. affinis or T. gerrardi. 



The Swallow-tail, by which very characteristic name the 

 species is known to the South Australian fishermen, was the 

 commonest fish taken on the cruise. The catch at Station 3 

 weighed 70 lb., while no less than 700 lb. weight was netted 

 at Station 4.

Ked Snapper. 



Contrary to local belief, the "Red Snapper" of South- 

 Australia is T . gerrardi, and not T . affinis ; not a single speci- 

 men of the latter was recognized in the hauls, nor have I so- 

 far seen it in the markets, though T . gerrardi is to be had 

 daily, often in large quantities. The colouration is similar to 

 that of the Eastern species, and may be thus described: — The 

 ground is iridescent silver suffused with blood-red ; this colour 

 occurs where the scales overlap, so that longitudinal lines are 

 produced, separated by the silver tint of the body of the scales. 

 The dorsal spines are colourless, the membrane red, whereas 

 the rays are red and the membrane untinted ; the coloura- 

 tion of the anal is similar to the soft dorsal. The pectorals, 

 and ventrals are slightly suffused with red; the caudal is red,. 

 with the outer and middle rays colourless.
