minute, circular ; the posterior a little larger, transversely oval, both 

 situated along the upper margin of the infraorbital. The mouth is 

 small, the lower jaw but little shorter than the upper; the angle is 

 situated opposite the anterior opening of the nostril. The notch of the 

 upper lip corresponds to the tubercle of the lower, which is notched 

 underneath. There are no teeth perceptible in the lips. On each 

 side of the vomer appears a transversal tubercle. In the young the 

 opercles appear to be scaleless. The vertical diameter in front of the 

 first dorsal spine equals the length of the head. A straight line from 

 the gill-opening to the root of the caudal fin contains 42 or 43 scales ; 

 an oblique in front of the anterior dorsal fin 13. 



Each scale is marked by a central line, horizontal in most, but almost 

 vertical in those immediately below and in front of the pectoral fins. 

 The third dorsal spine is situated at equal distance from the muzzle 

 and the root of the caudal fin. The length of this, as well as of the 

 two preceding spines, exceeds ^ of the vertical diameter of the body 

 beneath them, and it also slightly exceeds the extent of the base of the 

 fin itself. The fourth spine is about \ of the preceding three. On 

 each side of the base is an elongated scale. The second dorsal fin 

 commences at equal distance from the first dorsal spine and the root of 

 the caudal, opposite the third anal ray ; the base nearly equals the 

 length of the first ray. The caudal fin is slightly lunated : the length 

 of the first and fourteenth ray is about \ of the total length. The 

 length of the pectoral fins is 5 \ times in the total ; above the root 

 of each appears an elongated scale, formed like a knife-blade with the 

 back towards the upper margin of the fin ; its length is nearly \ of that 

 of the fin. At Pinang young individuals are numerous at all seasons.
