Length of head 5 to 5|, of caudal 6 to 6|, height of body 6 in the total length. Eyes — diameter 1/5 of 

 length of head, 1^ diameters from end of snout, Ij diameters apart. The bones of the forearm support the 

 thoracic edge, the keeled portion of the abdominal profile commences posterior to the ventral fin. Suborbital 

 ring of bones broader than the diameter of the eye, but only covering two-thirds of the cheek. Teeth — 

 pharyngeal, 5, 3, 1/1, 3, 5. Gill-rakers very short, 8 in the lower branch of the outer branchial arch. Fins — 

 dorsal commences slightly in advance of the anal, and in the last 1/3 of the distance between the hind edge of the 

 preopercle and the base of the caudal fin. Pectoral 1/3 longer than the head. Scales — extend forwards on the 

 head to above the nostrils. Colours — silvery. 



Habitat. — Sind, Punjab, N. W. Pro\ances, Bengal, Orissa, and Assam. It attains at least 9 inches in 

 length. 



B. — Bones of forearm do not srippoH the edge of thorax (Securicula).

Length of head 6 to 6i, of caudal 5, height of body 5 to 5^ in the total length. Eyes — diameter 3| to 

 3|- in the length of head, 3/4 of a diameter from end of snout. Posterior extremity of the maxilla reaches 

 to beneath the anterior third of the orbit. Suborbital ring of bones is half as deep as the diameter of the 

 orbit, and 2/3 wider than the uncovered portion of the cheek below it. Thoracic edge not supported by dilated 

 bones of the forearm. The serrated abdominal margin commences opposite the base of the pectoral fin. 

 Teeth — pharyngeal, crooked 5, 4, 2/2, 4, 5. Fins — dorsal commences opposite the anal. Pectoral as long as 

 the head but does not reach the ventral : lower caudal lobe the longer. Colours — silvery, caudal black 

 edged. 



Habitat. — Irrawaddi in Burma, extending northwards as far as Mandalay.

Length of bead 6, of caudal 6, height of body 5| to 6 in the total length. Eyes — diameter 3^ to 4 in 

 the length of head, 1 diameter from end of snout, nearly I diameter apart. The maxilla extends to below the 

 front edge of the eye. The bones of the forearm are not dilated and do not support the thoracic edge which 

 is smooth, the keeled portion commences opposite the pectoral fin. Suborbital ring of bones broad, but do 

 not touch the preopercular ridge. Teeth — pharyngeal, 5, 4, 3/3, 4, 5. Fins — dorsal commences above or slightly 

 behind the origin of the anal. The pectoral does not reach the ventral, nor the latter the anal. Caudal deeply 

 forked, the lower lobe the longer. Colours — silvery. 



Habitat. — Irrawaddi river at B.angoon, also the Salwein at Moulmein. It attains to at least 6 inches
