THE FISHES OF MALABAR. 
217 
length: jaws completely covered by the lips: posterior labial sulcus simple on either side. Centre of 
upper jaw emarginate to receive a knob which exists at the symphysis of the lower jaw. Opercles smooth. 
Scales small and deciduous. Lateral line curves downwards and ceases abruptly opposite ventral fin. 
Dorsal fin short, its base without scales, it arises behind the commencement of the ventrals, but does not 
extend so far as to above the anal. Anal short, without bony rays, commencing behind the end of dorsal. 
Branchial aperture cleft to below the eyes. Pharyngeal teeth in three rows, large, molar like, with their 
free surfaces concave or spoon-shaped, 1, 2, 8 | 3 , 2, 1.

Length, of head. of pectoral of base of dorsal y 1 ^, of base of anal y*y, of caudal ^ of total 
length. Height of head ^, of body of dorsal of anal 1 of total length. 
Eyes—The lower margins of the orbits are as close to the inferior, as their upper margins are to 
the superior profile of the head. Diameter I of length of head, a little more than \ a diameter 
from end of snout, 11 diameters apart. 
Profile rises gradually from the snout to the posterior end of the head, from whence there is 
a gradual decline to the caudal. The abdominal profile is rather more convex than that of the 
dorsal. Sides compressed, abdomen rather flat. Head compressed from side to side. Snout 
broad and depressed. 
Mouth moderate in size and oblique, lower jaw the longest, armed with a hook at its sym¬ 
physis, which is received into a corresponding emargination in the upper jaw. When the mouth 
is closed the upper surface of the lower jaw forms a portion of the superior profile of the head. 
Lips thin, covering both jaws. Muzzle apparently rather pointed when the jaws are closed. 
Intermaxillaries slightly protrusible. Preorbital triangular, apex below. Nostrils close to the 
anterior superior angle of the orbit, posterior broad and patent, divided by a valve from the 
anterior, the margins of which are raised. Opercle smooth and nearly triangular. Gill openings 
wide, and extending as far forwards as opposite the posterior margin of the orbits. 
Fins—Dorsal arises rather nearer to the caudal than to the snout, is slightly behind the origin 
of the ventral, but does not extend as far backwards as to above the commencement of the anal, 
both are square : anal situated in the posterior third of the body, and arising midway between the 
oi'bit and the end of the inferior lobe of the caudal. Caudal deeply lobecl. 
Teeth—Pharyngeal short, wide and transversely oval: summits concave, both from side to 
side, and from before backwards, in fact similar to the concave surface of a spoon, 3, 2, 1 | 1, 2, 3. 
Scales—Extremely deciduous, very small on the chest and as far as the ventral fins. 
Lateral line—Formed of long single tubes in each scale. It only extends along fifteen rows, 
curving downwards, and then ceases. 
Colours—Greenish above, silvery below. A bright silvery greenish yellow line separates the 
green of the back from the silvery sides and abdomen. Summit of head bright green. Inside of 
mouth and lips closely spotted with black. Fins colourless. Eyes white. 
Is not uncommon in the rivers and ponds. I have named the species after Dr. Jerdon, who 
records two of this genus which he discovered in Southern India. 
Habitat—Malabar.
