which the extent of the base but slightly exceeds \ ; the distance from 

 the caudal is \ of the total length. The anal commences opposite the 

 posterior half of the dorsal, which it resembles in form and length, 

 but the extent of the base is a little shorter ; the distance from the 

 caudal is contained 5| times in the total length. The three caudal 

 margins are slightly convex ; the length of the fin is f of the head. 

 The pectorals are broad, slightly rounded, the lower rays are but little 

 shorter than the upper which are contained 2f times in the length of 

 the head. The spines are rather short and fine, and disposed on two 

 separate spots. Above they cover a narrow oval spot from behind the 

 occiput to opposite the termination of the pectorals; laterally they 

 extend to within a vertical distance from the gill-opening of J of the 

 length of the head ; they are very distant and so deeply imbedded, as 

 easily to escape observation. Below they commence on a level with 

 the angle of the mouth, but opposite the posterior margin of the orbit, 

 their anterior margin is deeply excavated ; the lateral margin describes 

 an arch, which keeps a little beneath the lower part of the root of the 

 pectoral, and terminates behind at some distance in front of the anal, 

 which is situated nearly opposite the first dorsal ray. The spines of 

 the anterior half are crowded ; those of the posterior distant. Along 

 the arched lateral margin of the spinous spot appears an indistinct 

 abdominal soft keel, which afterwards continues straight to the lower 

 part of the root of the caudal. The other parts of the body are naked. 

 No lateral line is visible. Smaller individuals of this species are at 

 Pinang very numerous at all seasons.

Young. Head and body yellow brass-coloured ; head above, back 

 and upper half of the sides minutely dotted with black, so closely as 

 to appear blackish ; fins bright gamboge ; dorsal, caudal and anal each 

 with a single large irregular black spot, occupying the greater part of 

 these fins, but leaving open a narrow space along the base ; lips whitish 

 lilac. Iris shining brass-coloured.
