 of the snout, and is contained thrice and two-thirds in the length of the head. Inter- 

 orbital space concave, one-half of the width of the eye. Maxillary extending to behind

D. 10, A. 10, L. lat. 73, L. transv. 15/14. The height of the body is one-fourth 

 of the total length (without caudal), the length of the head two-ninths. The diameter of 

 the eye is one-fifth of the length of the head, and nearly two-thirds of the length of the 

 snout or of the width of the iuterorljital space. The head is remarkably small, with 

 narrow pointed snout, the cleft of the mouth being oblique and not reaching to the front 

 margin of the eye. Upper jaw overlapping the lower. Origin of the dorsal fin above the 

 root of the ventrals, midway between the snout and the root of the caudal fin ; fins gene- 

 rally small and short, the pectoral being not much more than one-half of its distance from 

 the ventral. Scales very indistinctly striated ; there are eight longitudinal series between 

 the lateral line and ventral fin. Pharyngeal teeth 5/2, pointed. Coloration uniform. 



This species is infested by a large Ligula, like so many other Cyprinoids of the Old 

 World. Length of specimens, 7\ and 9^ inches. Lake Hakou, Japan.
