FAMILY, V— CTPRINID^. 581 



Length of head 2/11, of caudal 1/4, height of body 2/7 of the total length. %e«— rather large, situated 

 in the anterior half of the head, 1/3 of a diameter from end of snout. Month small, horse-shoe shaped, with 

 the upper jaw slightly overhanging the lower. Abdominal profile more convex than that of the back. 

 Bwrbels — absent. Fins — dorsal two-thirds as high as the body below it, arising midway between the snout and 

 the base of th^ caudal fin, its last undivided ray is weak and articulated. Caudal deeply forked, with pointed 

 lobes. Lateral-ldne — incomplete, 14 rows of scales before the base of the dorsal fin. Coloms — silvery, with 

 a burnished silvery stripe along the side, and a black spot at the base of the caudal fin. Two first dorsal 

 rays and intermediate membrane deep black. 



Very similar in appearance to B. ambassis, but at once distinguished by the character of its last undivided 

 dorsal ray, which is articulated, and not osseous and serrated. 



Habitat. — Sind, Ravi river at Lahore, also Jubbulpore ; it is a small species, attaining about 2 inches in 

 length. Nearly all my specimens were spoiled before I was able to put them into spirit.

Length of head 3^, height of body 3 in the total length. Eyes — diameter 3 in the length of head, 

 1 4iameter from the end of snout and also apart. Mouth small, extending half the distance to below the orbit. 

 Lower labial fold interrupted. Ba/rbels — absent. J'ms— dorsal with the last undivided ray osseous, entire, 

 weak, and' nearly as long as the head : it commences midway between the snout and the base of the caudal fin. 

 Laieral-lime — incomplete, becoming lost opposite the posterior extremity of the dorsal fin : 3 rows of scales 

 between it and the base of the ventral fin : 9 rows before the dorsal fin. Golowrs — silvery, a black mark at the 

 base of each dorsal ray. , 



Sabitat. — A number of fry up to l^g inches in' length fi'om the Sitang river in Burma are in the 

 Calcutta Museum ; what they would be, when adults, it is difficult to determine, but, as the lateral-line is 

 incomplete, they probably never would grow to large fish. The species is very similar to Ba/rbus thermalis, C.V. 

 (not Gunther), but its head is a little longer, whilst the latter is from Ceylon.

Length of head 4, of caudal 4 to 4|, height of body 3 to 3| in the total length, ^i/es — diameter 3| to 4 

 in the length of the head, 3/4 to 1 diameter from end of snout, and li apart. Dorsal profile considerably 

 elevated. Height of the head equals its length : its upper surface flat : snout obtuse. Upper jaw the longer. 

 Lower lip very thick, the transverse fold interrupted. Barbels — absent. Fims — dorsal 1/2 as high as the body 

 below it, it commences nearer the base of the caudal fin than the front end of the snout, its upper edge is 

 straight : last undivided ray articulated. Pectoral as long as the head excluding the snout. Caudal forked. 

 Lateral-line — incomplete, ceasing about the seventh scale : 4 j rows between it and the base of the ventral fin : 

 12 rows anterior to the dorsal fin. Caudal peduncle as high at its base as it is long. Golowrs — silvery, darkest 

 superiorly : a dark blotch on the side of the tail on about the seventeenth and eighteenth rows of scales. 



Eabitat.— Gh.ua, Saidar Shah in the Punjab Salt range. This species was received from Dr. Waagen, 

 after whom I named it.

Length of head 4 to 4>i, of caudal 4, height of body 3i in the total length, ^j/es— diameter 2f to 2f in 

 length of head, 1/2 a diameter from end of snout, 1 diameter apart. A considerable rise to base of dorsal fin. 

 Mouth small : upper jaw slightly the longer. No lower labial fold. Fins— dorsal without any osseous ray, it 

 commences niidway between the end of the snout and the base of the caudal fin, its upper edge is oblique and its 

 height exceeds that of the body below it. Lateral-line— incomplete, the row of scales on which it is situated is 

 larger than the others, 2' rows between it and the base of the ventral fin : 8 or 9 rows before the base of the 

 dorsal fin. OoZowrs— silvery, the scales having dark bases : a black band along the top of the dorsal, another 

 across its middle also on the anterior anal rays. _^ 



Habitat.— Bengal, through the N. W. Provinces, the Deccan and Bombay, and down the Western coast 

 as low as Cottayam in Travancore. It attains 2 or 3 inches in length. The specimen figured (life-size) was 

 from Jubbulpore.
