Length of head 6f , of eandal 4, height of hody d\ in the total length, Hyes—AwmefcsT Z\ to 4 in the 

 length of the head, 1 to 1 J diameters from the end of snout and also apart. Body strongly compressed, and 

 rising abruptly from the nape to the base of the dorsal fin. Lower jaw overlapped by the upper when the 

 mouth is closed. Fins — dorsal arises rather behind the insertion of the ventral and midway between the front 

 edge of the eye and the base of the caudal fin, its last undivided ray strong, serrated, and its stiff portion rather 

 shorter than the head. Pirst three anal rays rather stiff. Caudal deeply forked. Laieral-lvne— complete, 5^ 

 (4 in some specimens) rows of scales between it and the ventral fin : 16 rows of scales anterior to the base of the 

 dorsal fin. Free portion of the tail as high at its base as it is long. Colov/rs — silvery, each scale with a dark 

 spot at its base. 



Habitat. — Tenasserim and throughout Burma (certainly as high as Mandalay) to the Malay Archipelago. 

 It attains at least 8 inches in length.

Length of head 6 to 6i, of caudal 4, height of body 3^ in the total length. Uyes — diameter nearly 2/5 

 of length of head, 1/2 diameter from end of snout, 1 diameter apart. Upper jaw slightly the longer. 

 Barbels — absent. Teeth — ^pharyngeal, sharp, crooked, 5, 3, 2/2, 3, 5. Fins — dorsal spine osseous, strong, and 

 posteriorly serrated, having about 15 teeth, the fin commences slightly anterior to the ventral, and midway 

 between the end of the snout and the base of the caudal, which last is deeply lobed. Scales — small and 

 deciduous. Lateral-lime — incomplete, becoming indistinct in the posterior two-thirds of the body, 6 rows of 

 scales between it and the base of the ventral fin : 15 rows before the dorsal fin. Golov/rs — light greenish, with 

 a silvery band along the side. A small black spot at the base of the anterior dorsal rays, and a black blotch 

 at the side of the tail. 



Habitat. — Madras, Orissa, Bengal, and Assam at least as high as Suddya. It attains about 3 inches in 

 length.

Length of head 5, of caudal 4, height of body 2| in the total length. Fyes — diameter 1/3 of length of 

 head, nearly 1 diameter from end of snout, and IJ apart. Body elevated. A slight concavity over the nape, 

 followed by a considerable rise to the base of the dorsal fin. Barbels — absent. Fins — the dorsal 3/5 as high as 

 the body, its last undivided ray osseous, moderately strong and serrated, as long as the head without the 

 snout : the fin commences rather anterior to the insertion of the ventral, and midway between the anterior 

 extremity of the orbit and the base of the caudal, which latter is forked in its last half. Lateral-line — 

 incomplete, ceasing after 8 or 10 scales : 4 to 4| rows of scales between it and the base of the ventral fin : 

 9 rows before dorsal fin. Free portion of the tail as high at its base as it is long. Colours — a large round black 

 spot on the middle of the side above the posterior portion of the anal fin : opercles lake colour. Pins orange, 

 dorsal with its upper half blackish. 



Nainee tal specimens have the dorsal spine much less coarsely serrated than those from the plains, from 

 whence they were introduced not many years since ; they have also a darkish band along the side. 



Habitat. — ^Assam, Lower Bengal, Orissa, Behar, N. W. Provinces, Punjab, and the Deccan : attaining at 

 least 5 inches in length.
