equal, the teeth and tongue normal. The dorsal occupies the com- 

 mencement of the posterior fifth of the back ; it is fan-shaped, with the 

 first ray undivided ; the longest rays are \ of the head, or twice the 

 extent of the base of the fin. The posterior margin of the caudal is 

 convex ; the longest rays are \ of the head. The anal resembles the 

 dorsal ; it commences, nearly opposite the middle of the distance 

 between the dorsal and the caudal. The pectorals are rounded, their 

 length equals that of the dorsal. The spines are rather long, very fine, 

 hair-like and crowded. On the back they commence from between the 

 nasal tentacula and extend to the caudal, in front of the base of which 

 there is but a small naked space. The lips, the chin and the space 

 inside the pectorals are also spineless. A single individual was observed 

 at Pinang in December 1842. This species is nearly allied to T. 

 virgatus, Richardson, (ZooL Erebus and Terror, 62, PI. XXXIX. Fig. 

 8-9,) from which it differs in the dorsal being situated farther back ; in 

 the relative position of the latter fin and the anal, and in the greater 

 number of black lines of the back. In the present the latter are twelve ; 

 in T. virgatus six. It is also allied to T. meleagris, Solander.*
