Locality : Red Point, on 



Head 2£ in length to hase of caudal ; depth 2f. Dorsal 14; 

 anal 18 or 19. "Vertebrae about 40. 



Fish rather short and deep, with large head and projecting 

 lower jaw. Dorsal triangular, its front rays the longest, half 

 again as long as the dorsal base. Origin of dorsal behind that of 

 ventrals, at about middle of the total length ; -J of dorsal base

in front of anal. Anal larger than dorsal, its anterior rays 

 elongated, its base separated from the caudal by a distance 

 slightly less than the depth of the peduncle. Origin of 

 ventrals about equidistant between origins of pectorals and of 

 anal. Peduncle rather deep, equal to base of dorsal. Caudal 

 not completely preserved, but obviously forked as shown by 

 the elongation of the upper rays and the shortness of the 

 middle ones in the type specimen. 



Remarks. — The Cyprinid fishes are distinguished into genera 

 largely by the character of their pharyngeal teeth, and since 

 these are not preserved in the present specimens one cannot be 

 absolutely certain as to the generic determination. However, 

 a comparison with figures of various genera would indicate from 

 the proportions of the fish, the position and size of the
