Ko. 1334. JAPANESE CYPRINOID FISHES— JORDAN AND FO WLER. 825 



geal teeth in 3 rows, several with grinding surface, and compressed, 

 and those in the inner row small; nostrils together, in front of the 

 eye and about over the base of the maxillary barbel so that they are 

 much nearer the eye than the tip of the snout; interorbital space 

 broad and flattened like the rest of the top of the head. Gill-open- 

 ings large; gill-rakers 7 — 12, some of the lower ones rudimentary; 

 those wliich are well developed short and fleshy. Intestine short. 

 Peritoneum silver\'. 



Scales large, of more or less uniform siz(>. and cycloid; no scaly 

 pectoral flap; ventral flap moderate. 



Dorsal tin inserted nearer the tip of the snout than the base of the 

 caudal, armed with a long, straight, smooth spine, the anterior dorsal 

 rays the longest, so that when the fln is depressed the flrst reaches 

 beyond the others; anal entirely behind dorsal and midway between 

 the origin of the ventrals and the base of the caudal; caudal deeply 

 forked, the lobes pointed; pectorals reach three-fourths the distance 

 to the ventrals; origin of ventrals behind that of dorsal, about mid- 

 way between tip of snout and base of caudal, and reaching a little 

 more than half the space to anal; caudal peduncle compressed, its least 

 depth a little over 3 in head. Lateral line continuous and slightly 

 decurved in front. 



Color in alcohol, brassy-brown above, the sides and lower surface 

 silvery. 



Length, 9f inches. 



This description from an example from the Yodo River, in Osaka. 



Fresh waters of Japan. Of this species we have examples from 

 Lake Jinsaburogata at Nishitsugaru, Aomori (collection Sotaro Saito), 

 the Yodo River at Osaka, the .Chikugo River at Kurume. and from 

 near Tokyo {Allatross collection).

 Leucogobio Gunther, Ann. Ac. Sci. Petersburg, 1896, p. 212 {herzemtdnl) . 



Body oblong, slightly compressed. Head elongate; eye moderate; 

 snout not projecting; mouth oblique, the jaws about equal, and the lips 

 narrow and simple; the maxillary barbel sometimes as long as the eye; 

 teeth 6 or 5 and 3, 2 or 1—6 or 5-5—3, 2 or 1; interorbital space 

 broad; nostrils close together. Intestine short. Peritoneum generally 

 silvery. Scales large, cycloid, and not imbricated. Dorsal inserted 

 midway or in advance of space between tip of snout and base of 

 caudal; caudal emarginate. Lateral line nearly straight or only slightly 

 decurved and continuous. This genus is related to Gobio, dilfering in 

 its mouth, which is like that of Leuchcus. It embraces two Chinese 

 species, Ltucogohlo Iwrzemteh/i and Leuco(johiv hvnkdm, and four 

 Japanese species.
