THE FISHES OF MALABAR. 
71 
Eyes—Eacli having rather a broad circular adipose membrane, diameter § of length of head, 
1 ] : diameters apart. 
Teeth—On either side of both jaws are upwards of eighteen lancet shaped teeth, many of 
which however are often absent. The middle ones in the lower jaw are the largest. On the 
anterior part of the vomer appears a pointed triangular spot with velvety teeth, and on each palatine 
and pterygoid bone a rather broad continued line of similar teeth. Others exist at the root 
of the small oval flattened tongue, and on the margin and internal surface of each hyoid. 
Fins—The spines of the 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 equal to the diameter of the eye, is two- 
thirds of the length of the second, which is shorter than the third. The fourth, the longest, is 
one-fourth of the length of the head; the rest gradually decrease; the sixteenth is so short and 
slender that it may easily escape observation. The anterior spurious fin is often connected by a 
short membrane to the second dorsal and anal. Each caudal lobe equals the length of the head. 
The length of the pectorals is two-seventeenths of the total length ; the ventrals one-third of the 
pectorals. 
Scales—Are placed as in the last species. 
Lateral line—Consists of a series of short rectangular elevations, at first in upper fourth of 
body, from whence it gradually deviates towards the termination of the second dorsal, and 
again declines to below the middle of the body opposite the fifth finlet, where it ascends on to the 
lateral keel. \ 
Colours—The same as in the last species, the C. Commersonii. After death several series of 
irregularly disposed black spots appear above the lateral line, whilst beneath it there are three or 
four rows of longitudinal short linear spots, each resembling an interrupted line. 
Grows to two feet in length. 
Habitat—Seas of India and Malaysia.
