1868.] SURGEON F. DAY ON INDIAN FISHES. 583 



margin of praeorbital bone its longest. Operculum one-third higher 

 than broad. 



Teeth. Pharyngeal teeth crooked, pointed, in three rows, 

 5, 3, 2/2, 3, 5. ' 



Fins. Dorsal commences slightly in advance of the ventral, and 

 midway between snout and base of caudal ; its first two undivided 

 rays are very short ; the fourth is cartilaginous and articulated, in 

 large specimens it becomes osseous, but is never strong. Anal begins 

 midway between the posterior extremity of operculum and the pos- 

 terior extremity of the caudal fin, which last is deeply lobed. 



Scales with numerous horizontal striae ; there is an exceedingly 

 low row along the base of the dorsal fin, aud one hardly higher along 

 the base of the anal. 



Lateral line curves downwards along the first six or seven scales, 

 ■when it becomes straight and passes along the middle of the side of 

 the body. 



Colours. Silvery, with a tinge of yellow, but without any spots or 

 markings. 



Hab. Kurnool, where it is exceedingly common in both the Hin- 

 dree and Tamboodra rivers. It grows to upwards of a foot in length, 

 and is esteemed good eating by the natives, but, like the rest of its 

 genus, is bony. 



I have named this species after Dr. A. Gimther, F.R.S., who was 

 good enough to point out that the name that I had originally given 

 to it was preoccupied. 



Barbus ambassis, sp. nov.

Length of specimens to 2^^^ inches. 



Length of head -f-^, of base of dorsal ^, of base of anal -fj, of cau- 

 dal \ of the total length. Height of the head -fj, of body \, of 

 dorsal -j^y, of ventral -j^y, of anal 4- of the total length. 



Eyes without any adipose lids ; nearly ^ of length of head, 1 dia- 

 meter apart, | a diameter from end of snout. 



Opening of mouth oval; upper jaw shghtlythe longest; no horny 

 covering to the lips, which are thin. Maxilla extending to nearly 

 beneath the anterior margin of the orbit. Suborbital ring of bones 

 covers the cheek. No barbels. 



Pharyngeal teeth sharp, curved, 5, 3, 2/2, 3, 5. 



Fins. Uorsal arises slightly anterior to the ventral, midway be- 

 tween snout and the base of the caudal ; its third undivided ray is 

 very strong, flattened, and strongly serrated posteriorly, having about 

 fifteen sharp teeth ; superiorly it ends in a soft point. Anal arises 

 midway between the snout and the posterior extremity of the caudal 

 fin, which last is deeply lobed. The pectoral scarcely reaches the 

 ventral, which latter just extends to the anal. 



Scales small, very deciduous. Six rows between the lateral line 

 and the base of the ventral fin. No enlarged row along the base of 

 the anal fin.
