Total length : 3f inch. 



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

 bordering on the profile, is a little nearer the muzzle than the gill-open- 

 ing ; its greater diameter, rising obliquely backwards, is \ of the length of 

 the head; the distance between the anterior angles is two such diameters ; 

 three between the posterior. The nostrils have two small apertures, 

 between which rises a small tentacle. The teeth and tongue are normal. 

 The rounded dorsal is situated between the penultimate and posterior 

 fourths of the back ; the two first rays are undivided, the fifth and sixth, 

 the longest, are contained 2 \ times in the length of the head, and they 

 equal the extent of the base. The caudal is broad, with the posterior 

 margin rounded ; its length § of the head. The first undivided anal ray 

 commences opposite the termination of the dorsal fin, which it resembles. 

 The pectorals are broad, rounded ; their length is a little less than that 

 of the dorsal. The spines commence immediately behind the upper 

 lip, and terminate a little behind the dorsal, and immediately behind 

 the anal, leaving the tail naked. In form they resemble those of T. 

 carduus. Single individuals, none of which exceeded the length stated, 

 were observed at all seasons at Pinang.
