OP NEW SOUTH WALES. 401 



nasal openings two on each side, opposite each other, and placed 

 on a single, more or less prominent papilla ; a distinct fold along 

 thelower part of the body and tail ;" forming the genus Gastrophystis, 

 of Muller ; upper parts covered with small spines beginning 

 rather in front of the eyes, and extending to the base of the dor- 

 sal ; others cover the belly, but no transverse h"nes of these 

 spines join one another on these parts ; the head is quadrangular, 

 and is more than the distance between its posterior extremity and 

 the base of the dorsal ; caudal forked ; tail slightly compressed 

 and naked; anterior part of the head elevated ; cheeks entirely 

 smooth, with a line forming an angle in front, and another below 

 the eye ; the upper parts are brown ; the sides of the head silvery ; 

 the fins yellow ; no defined silvery bands on the sides. 



The specimen is eight and a half inches long, and is from 

 ]\roreton Bay ; it belongs to the Brisbane Museum. 



The length of the head is more considerable than is said in 

 Dr. Gunther's description ; this fish certainly belongs to Richard- 

 son's spadiceus from the Chinese and Indian Seas, and may be 

 different to the typical lunaris. 



Tetrodon amabilis 



Nasal organ very conspicuous, simple, without any fringe or 

 tentacles ; no fold along the lower part of the tail ; body covered 

 with short villiform spines ; dilated belly, covered with rather 

 spaced tubercles ; eight dorsal rays, the body is entirely of a dark 

 reddish brown ; the belly of a fine orange colour ; this is covered 

 with numerous broad, black, concentric stripes ; the fins are of a 

 bright yellow ; the caudal is orange with numerous black spots, 

 forming several irregular transverse bands ; the anterior profile 

 of the head is concave ; it becomes very convex over the eyes, 

 and runs nearly straight along the back. 



The only specimen (taken on the 20th July, 1877) I have seen 

 of this pretty fish is four and a half inches long.
