THE FISHES OF MALABAR. 
187 
B. vi. (?) D. l | 0. A. 12. 
Eyes—Diameter of length of head, 1 diameter apart. 
Front of month rounded, Upper surface of head granulated, and twice as long as wide. 
Occipital process long, straight, and extending half way to the base of the dorsal. Maxillary cirri 
pass the anal. 
Fins—First dorsal pointed, higher than the body: the adipose dorsal equals the anal in its 
length. Lobes of caudal pointed, the superior the longest. 
Colours—Grey above, silvery on the sides and white beneath. The dorsal black at its base, 
and superiorly; the other fins blackish. Yentrals fawn colour, with white edges. 
Grows to three inches in length. 
Habitat—Rivers and fresh waters of Malabar. 
Genus HYPSELOBAGRUS, Bleeher. 
Macrones, pt. Dumeril. 
Branchiostegals, from eight to ten. Head conical, compressed. Opercular hones articulated and move- 
able. The occipital process which is rugose touches the basal bone of the dorsal fin, or should there be an 
intermediate shield they articulate one with the other, and there is no intermediate free space. Back 
compressed. Eyes free with subvertical lids. Mouth anterior. Cirri eight, one pair to posterior nasal 
orifice which is some distance apart from the anterior which is tubular; one pair to maxillaries: and 
two pairs to mandibuke. Teeth in both jaws sharp and in many rows, those on the vomer and palate 
villiform and continuous in one semilunar band. Dorsal inserted before ventral, with a sharp serrated 
spine and seven rays: adipose dorsal in length equal to, or of greater extent than the anal which is 
short. Pectoral spine denticulated. Caudal bilobed. Interbranchial membrane deeply cleft. Air bladder 
present. 
Hypselobageus ARMATUS.

Eyes—Transversely oval: horizontal diameter -|, vertical diameter | of length of head, f of a 
horizontal diameter apart, | a diameter from end of snout. 
Head compressed, a gradual rise from snout to first dorsal. Upper jaw the longest over¬ 
lapping the lower, the cleft of the mouth hardly exceeds one-fourth of its gape, and does not 
extend posteriorly so far as the anterior margin of the orbit, the inferior surface of 
the intermaxillaries is on a level with the lower margin of the orbit. Upper surface of 
head rugose with a central longitudinal groove extending nearly but not quite to the 
base of the occipital process which is rugose. The occipital process (including its 
second bone) is three times as long as wide, the second bone is closely articulated to it 
and also touches the basal bone of the dorsal fin. The nostrils are wide ajiart, the 
posterior having a cirrus. The nasal cirri extend to as far as the posterior margin of the orbit: the
