series from the root of the pectoral to the anterior part of the caudal 

 contains about 34. The length of the head is about \ of the total. 

 The second ray of the anterior dorsal is the longest, terminating in a 

 filament ; its length is double that of the greatest vertical diameter, or 

 a little less than £ of the total length. The teeth are minute, velvety, 

 of nearly equal length. This species appears not to be numerous at 

 Pinang.

 the base, upper margin orange, between the rays 3 to 5 white oval 

 spots, forming transversal series ; caudal similarly coloured, but with

Total length : 6 inch. 



The head is a little depressed, the profile slightly sloping, the length £ 

 of the total ; the breadth at the nape is contained 2\ times in the depth, 

 which exceeds one half of the length of the head; the cheeks are tumid ; 

 eyes obliquely oval, nearly vertical, situated nearer the posterior angle of 

 the preopercle than the muzzle ; their greatest diameter is about £ of 

 the length of the head ; their distance f of the greatest diameter ; the 

 muzzle is bluntly rounded, the lower jaw slightly projecting beyond the 

 upper ; the gape is wide, the angle of the mouth is beneath the posterior 

 margin of the orbit. The teeth of the upper jaw are generally minute, 

 but the anterior 4 or 5 on each side a little longer than the rest ; 

 the external series on each side of the lower jaw consists of 9 teeth, of 

 which the two last towards the angle of the mouth are stronger, and 

 much longer than the rest, and recurvous. These teeth M. Valen- 

 ciennes compares with the fangs of venomous serpents. The other 

 teeth are minute like those of the upper jaw. On the lower part of
