fully taken from life. The altitude of the deepest part of the body is con- 

 tained four and a half times in the entire length, and the head and caudal are 

 each equal in length to the depth of the body. There are forty-four scales 

 along the lateral line, and fourteen in an oblique row from the base of the 

 ventrals to the dorsum. The dorsal fin is placed somewhat nearer to the 

 nape than to the base of the caudal fin, and the length of its base is equal 

 to the depth of the body ; the ventrals are placed opposite the dorsal, and the 

 space between the anal and caudal is equal to half that between the former 

 and the ventrals. The fin rays are, 



D.16: P.17: V.9: A.7: C.19. 



The eyes are placed almost in the anterior third of the head. Buchanan 

 states that the pupils are circular, but I have found them oval, with the long 

 diameter vertical. In the variety called Rewah, however, the pupils of those 

 I have examined are circular, and if we could rely on such peculiarities as con- 

 stant, they would afford an excellent character by which we might distinguish 

 the species in very difficult cases. 



The mouth is placed at the end of the head, having two small cirri placed 

 anteriorly on the upper lip. The under jaw is formed of a very slender rim 

 composed of two bones meeting in the middle at the chin, where they are 

 soldered firmly together. 



The outer extremities of these ossa siagona* as they may be named for 

 convenience, are articulated above to the corresponding extremities of the 

 intermaxillaries, and behind to the anterior extremities of what Cuvier named 

 in the Perch, the angular bone. It has already been shown that the angular 

 bones really form the lower jaw both in the Cirrhins and in the Barbels, Avith 

 this difference, that in the one case they are united, and in the other 

 unattached by a bony union in front. In the Gudgeons, however, and in 

 this species in particular, the angular bones are nearly parallel to each other. 



* From Sja-yov, the jaw bone.
