CARP10 KOLLAK1I. 



103 



The body is compressed and high, two and a half times as long as high, with 

 a greatly arched back, so that its form closely resembles that of the Crucian 

 Carp. The head is about one-fifth the total length, and is longer than high. 

 The diameter of the eye is one-fifth of the length of the head. The angle 

 of the oblique mouth does not reach quite as far back as the nares, and the 

 centre of the mouth lies in a plane that would pass through the orbit and 

 the middle of the body. It resembles the Carp in having two pairs of 

 barbels. They may be short, and are sometimes only one line long. The

contour of the forehead ascends from the rounded snout in a nearly straight 



or slightly concave line to the back, where the highest curve is passed before 



the commencement of the dorsal fin. The large dorsal fin is opposite to the 



ventral fin ; it is more than twice as long as high, and its base is rather 



more than one-third of the length of the fish. The fourth bony ray ends 



in a curved point, and is of the same 



height as the succeeding jointed rays, 



though towards the end of the fin the 



height of the jointed rays diminishes 



one half. The anal fin is higher than 



long, and reaches back towards the 



caudal fin rather farther than does the 



dorsal. As in Cyprinus carpio, its bony 



ray is stronger than that of the dorsal. 



The ventral fins do not reach back to the vent, and the pectoral fins do not 



reach back to the ventrals. The tail is evenly lobed. 



The scales are like those of Cyprinns carpio ; the largest only slightly 

 exceed the diameter of the eve.
