FAMILT, V— CYPRINID^. 693 



Length of head 4i to 5^-, of caudal 5, height of body 3|- to 4 in the total length. Eyes — diameter 2| to 

 Si in the length of the head, 2/3 to 1 diameter from the' end of snout, and 1\ apart. Third suborbital 

 bone thrice as deep as the uncovered portion of the cheek below it. The maxilla reaches to beneath the first 

 third of the orbit : the adult has open pores on both jaws and snout. Axillary process reaches to above the base 

 of the pectoral fin. Barbels — absent. Fins — dorsal varies considerably, commencing midway between the eye 

 and the base of the caudal fin, it is elevated in some specimens but not in others, while the last ray may extend 

 (especially in the young) almost to the base of the caudal fin. The pectoral reaches to above the ventral, and 

 in the young has its outer rays thickened. The ventral does not extend to the anal in the young, its inner rays 

 are very thick. Anal commences under the middle or end of the dorsal fin. Lateral-line — 2-1- rows of scales 

 between it and the base of the ventral fin : 16 rows before the base of the dorsal fin. Colours — of a dull green 

 in the adult, with from 9 to 11 vertical dark bands on the body : dorsal and caudal fins edged with black. The 

 young (B. ]}ainllatus) have the back gray, the sides silvery shot with gold, and from 7 to 9 narrow deep blue 

 vertical bands. Fins yellow, the dorsal and caudal stained externally with black. 



Habitat. — Assam, the Ganges and its branches, Bengal and Orissa. It attains 5 inches or more in 

 len<Hh. FiiT. 1 shows how much more forward the anal is in the young than in the adult fig. 2.

Length of head 4| to 4|, of caudal 4 J to 5, height of body 5 j to 6 in the total length. Eyes — diameter 4 to 

 6 in the length of the head, 1 to I5 diameters from the end of snout and apart. Cleft of mouth deep, extending 

 nearly 1 diameter behind the orbit. Snout compressed : upper jaw the longer. A well-developed knob above 

 symphysis of lower jaw. Suborbitals very broad, more especially the hindermost which is nearly behind the 

 vertical from the posterior margin of the orbit, and almost covers the cheek. Barbels — a rudimentary rostral 

 or maxillary pair may be present. Fins — dorsal commences midway between the posterior extremity of the 

 orbit and the base of the caudal, being opposite the interspace between the ventral and anal fins. Caudal 

 forked, lower lobe slightly the longer. Lateral-line — complete, 2 rows of scales between it and the ventral fin : 

 23 rows before the base of the dorsal fin. Colours— silYerj shot with purple, one or two rows of blue spots 

 alone the side. Lower caudal lobe orange, its upper lobe with a dark edging, and a dark band along the upper 

 half of the lower lobe. 



Habitat. — Irrawaddi from Prome to Mandalay ; attaining at least 7 inches in length.

Length of head 4f to b\, of caudal 4f , height of body 4-| in the total length. ii;//es— diameter 4 to 4^ 

 in the lengtli of the head, 1 to IJ diameters from the end of of snout, and 1^- apart. Abdominal profile more 

 convex than the dorsal. Head compressed, snout pointed. Upper jaw slightly the longer when the mouth is 

 closed : symphysial knob not developed. The posterior extremity of the maxilla reaches to beneath the middle 

 of the eye. Suborbital ring of bones broad, the third being about equal to twice the extent of the uncovered 

 portion of the cheek below it. The width of the opercle equals half the distance between the middle of the 

 eye and hind end of the head. Axillary process well-developed, having a soft scaled prolongation. Barbels — 

 very rudimentary or entirely absent. Fins — dorsal commences midway between the hind edge of the eye and 

 the base of the caudal fin, the anal being behind the vertical from its last ray. Pectoral as long as the 

 head excluding the snout. Caudal deeply forked, lower lobe the longer. Lateral-line —Z\ to 4i rows of 

 „cales between it and the base of the ventral fin : 30 rows before the base of the dorsal fin. Colours — bluish 

 alono- the back, becoming silvery on the sides and beneath : two or more rows of blue spots and blotches, Laving 

 a vertical character, along the sides. Dorsal and caudal fins dark gray, with a light pinkish edge : the other 



fins yellowish. 



Habitat. — Bengal and Assam, attaining at least 5 inches in length.
