margins convex ; its length is § of the head. The pectorals are broad, 

 rounded ; their length equals that of the dorsal. There is no lateral 

 line. The spines are rather long, fine and somewhat distant ; above 

 they extend from between the eyes to near the dorsal ; beneath from 

 behind the throat to near the anus, which is situated a little in front of 

 the anal. Young individuals of this species are at all seasons exces- 

 sively numerous on the Malayan coasts. In general form and in dis- 

 tribution of colours it bears a striking resemblance to T.fluviatilis, 

 Buchanan Hamilton,* which latter differs in having distinct simple 

 nostrils, in number of fin rays and other characters. The present 

 belongs to the Sub-Gen. Arothron t Muller.f

Total length : 6 inch. 



The length of the head is contained 3y times in the total. The eye is 

 situated nearly in the centre of the length of the head, bordering upon the 

 profile ; the horizontal diameter is \ of the head ; the distance between 

 the anterior angle of the orbits is nearly three diameters ; between the 

 posterior four. No nostrils appear, but their place is supplied by two 

 small black tentacles, the one close above the other. The jaws are nearly
