582 SURGEON F. DAY ON INDIAN FISHES. [NoT. 26, 



Cleft of mouth extending but little more than half the distance to 

 beneath the anterior margin of the orbit, but the posterior extremity 

 of the maxilla to nearly below the same margin. Lower jaw slightly 

 the shortest. Nasal barbels extend to the anterior margin of the 

 orbit ; the maxillary barbels are equal to 1 1 diameter of the orbit 

 in length. In the largest preserved specimen one of these barbels 

 is subdivided into three at its external extremity. In one moderate- 

 sized specimen a number of glands open along its suborbital ring 

 of bones. 



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



Fi)is. Dorsal arises slightly in advance of ventrals ; first two undi- 

 vided rays osseous but minute, third not half so long as fourth, 

 which is moderately bony, smooth, ends in an articulated extremity, 

 and is then as long as the first branched ray. Upper margin of the 

 fin concave. Pectoral extends to ventral, which does not extend, by 

 the width of two scales, to the anal, wliich last fin commences mid- 

 way between the extremity of the caudal and base of the pectoral ; 

 its first undivided ray minute, its third as long as the first branched 

 one. Anal laid flat reaches the base of the caudal. Caudal almost 

 lunated, its central rays almost equal to the longest of the outer rows. 



Scales. Four and a half rows between lateral line and base of dorsal 

 fin, and two and a half between lateral line and base of ventral. 



Lateral line in single tubes, curves very slightly downwards, and 

 opposite the end of the ventral proceeds direct to centre of base of 

 caudal fin. 



Colours. Silvery above lateral line, and with a dash of yellow below 

 it. Fins of a bluish tinge, especially the caudal. Eyes golden. 



This magnificent Carp grows to a very large size: one was brought 

 weighing 38 pounds ; and its size may be imagined when the speci- 

 men 39 inches long did not weigh 14 pounds. It is said to grow to 

 50 or GO pounds weight, and is very common at Kurnool, where it is 

 esteemed as food by the natives. It is one of the Mahseers of India. 



I have named it after my esteemed friend and correspondent A.

Length of specimens from 2 to 5-,^ inches. 



Length of head a little above ■!•, of pectoral 1, of caudal f , of base 

 of dorsal ^, of base of anal J- of the total length. Height of head J-, 

 of body 5, of dorsal fin |, of ventral ^, of anal ^ of the total length. 



Ej/es. Upper margin near the profile ; diameter ^ of length of 

 head, 1 diameter from end of snout, and 1 diameter apart. 



Body rather compressed ; a considerable rise in the profile from 

 the occiput to dorsal fin. Snout somewhat obtuse. 



Lower jaw slightly shorter than the upper ; the posterior extre- 

 mity of the maxilla extends nearly to beneath the anterior margin of 

 the orbit. The maxillary cirri are equal to the diameter of the orbit 

 in length, extending to slightly beyond its centre. The superior
