dorsal yellowish white, the latter minutely dotted with black towards 

 the margin ; first dorsal, ventrals and anal whitish, the latter sparingly 

 dotted with brown ; upper part of opercle with a bluish black spot. 

 Iris silvery ; adipose fold of the orbit pale amber-coloured.

Total length : 9f inch. 



The length of the head slightly exceeds 3^ in the total, measured 

 to the centre of the posterior margin of the caudal ; the depth at 

 the occiput is f of the length of the head. The diameter of the orbit is 

 3J in the latter ; the opening of the adipose fold of the orbit is verti- 

 cally oval. The lower margin of the opercle is nearly straight, or 

 slightly concave about the middle. The greatest vertical diameter of 

 the body in front of the second dorsal is 3-g- in the total length. The 

 arched portion of the lateral line terminates opposite the anterior 

 fourth of the second dorsal ; the rest is straight and covered by 37 

 to 40 plates, none of which in height exceeds ^ of the greatest vertical 

 diameter of the body. The length of the falcated pectorals is 3^ in 

 the total. The last dorsal and anal ray is stronger and more elongated 

 than the preceding ones, and as the connecting membrane easily 

 becomes torn, these two rays acquire the appearance of spurious ones. 

 M. M. Cuvier^and Valenciennes describe C. xanthwus as corresponding 

 in every respect to the present species, except in its having a series of 

 eight or nine dorsal spots of a darker blue than the rest of the back. 



From C. affinis, Riippell, (Neue Wirbelth. Fiscke, 49, Tab. 14, 

 Fig. 1.) the present also differs but slightly; in affinis the head is 

 \ of the total length, and the pectorals equal the length of the head : 

 both are therefore shorter than in the present. The first dorsal spine 

 is \ of the fourth, the longest. In the present the first spine is 2^ in 

 the length of the third and fourth, which are of equal length. Single 

 individuals occur at all seasons at Pinang. They are eaten by the 

 natives.
