 lower part of the tail. Dorsal fiii short, with less than nine branched 

 I'ays, inserted opposite to the root of the ventrals. Anal fin with ten 

 or more raj's. Barbels none. The maxiUary reaches to or behind 

 the front margin of the orbit. Suborbitals not dilated. GiU-rakers

1. Opsariiclithys uncirostris. 



Leuciscus imcu'ostris, Schleg. Faim. Japan. Poks. p. 211, pi. 102. fig. 1.

D. 9. A. 12. L. lat. 50. L. transv. 11/8. 



Mouth very wide, the maxillary extending to below the middle of 

 the eye. Each intermaxillary with a strong prominence on each 

 side near its upper end, fitting into a notch of the loM'er jaw. The 

 height of the body is contained foxu' times and two-thirds in the 

 total length (without caudal), the length of the headttrice and two- 

 fifths. The origin of the dorsal fin is midway between the end of 

 the snout and the root of the caudal. None of the anal raj's pro- 

 longed. Coloration imiform. {Schleg.)

2. Opsariichthys sieboldii. 



Leuciscus sieboldii, Schleg. Fuun. Jupon. Fviss. p. 211, pi. 101. fig. 5. 

 D. 9. A. 12. L. lat. 65. L. transv. 14/8. 



Mouth rather A^ide, the maxillary scarcely extending beyond the 

 vertical from the front margin of the eye. The front part of the 

 anal fin is elongate, but scarcely reaches the root of the caudal if 

 laid Ijackwards. Pectoral fui not extending to the ventral. The 

 height of the body is a little more than the length of the head, which 

 is one-fourth of the total (without caudal.) Suborbital ring very 

 narrow. Coloration imifonn. (StJiJcrf.)

3. Opsariichthys temminckii. 



Leuciscus temminckii, Schkr/. Faun. Jajio/i. i'of'.w. p. 210, pi. 101. 

 fig. 4. 



D. 9. A. 13. L. lat. 50. L. transv. 10/9. 

 Mouth rather wide, the maxillary extending somewhat beyond the 

 vertical from the front margin of the eye. The foiu" or five ante- 

 rior branched anal rays are elongate (in adult specimens), extending 

 to, or nearly.to, the root of the caudal, if laid backwards. Pectoral 

 fin not extending to the ventral. The height of the body is nearly 

 equal to the length of the head, which is scarcely more than one- 

 fourth of llie total (without caudal). Suborbital ring very narrow, 

 the middle byucs being only ouc-thu'd as broad as the orbit. (Snout
