the posterior caudal margin, but \ to the centre of a vertical line 

 between the points of the caudal lobes. The diameter of the orbit is 

 4^ in the length of the head ; the margin of the orbit supports a rather 

 broad circular adipose membrane. The distance of the eyes across the 

 forehead is 1^ diameter. On each side of both jaws appear upwards 

 of 18 lancet-shaped large teeth, of which, however, more than 10 or 

 11 are seldom present. The middle ones of the lower jaw are 

 the largest. On the anterior part of the vomer appears a pointed 

 triangular spot with velvety teeth, and on each palatal and pterygoid 

 a rather broad continued line of similar teeth. Others appear at the 

 root of the small oval, flattened tongue, on the margin and internal 

 surface of each hyoid bone. The scales are perceptible in the places 

 noted under Cybium commersoni. The greatest vertical diameter 

 slightly exceeds \ of the total length. The lateral line, a series of 

 short rectangular elevations, commences following the upper fourth of 

 the body, from which it gently deviates towards the termination of the 

 second dorsal fin; from thence it continues declining to below the 

 middle of the body, opposite the fifth spurious fin, when it slightly 

 ascends towards the strong keel in front of the caudal fin. The spines 

 of the anterior dorsal fin are very slender, and the membrane is easily 

 detached, so as to leave the filamentous points of the anterior and the 

 whole of the posterior five or six very short spines unconnected. 

 The anterior spine, scarcely equalling the diameter of the eye, is f 

 of the length of the second, which is shorter than the third. The 

 fourth, the longest, is \ of the length of the head ; the rest gradually 

 decrease; the sixteenth is so short and slender that it easily may 

 escape observation. The anterior spurious fin is often by a short 

 membrane connected to the second dorsal and anal. Each caudal lobe 

 equals the length of the head. The length of the pectorals is &J in 

 the total ; the ventrals ^ of the pectorals. 



At Pinang this species occurs at all seasons, but not in numbers. In 

 quality it resembles C. commersoni, and like it, a solitary, stray one, 

 may during the cold season, be seen in the fish bazars of Calcutta.
