60 MU. C. TATE REGAN ON [Feb. 4, 



series, 4 or 5 in a transverse series from origin of dorsal to lateral 

 line, 3 or 3 1 between lateral line and base of ventral fin. Dark 

 longitudinal stripes along the series of scales, broader and stronger 

 above the lateral line, fading out below ; fins pale. 



Three specimens from Ohong-ju, the largest 75 mm. in total 

 length. 



The genus Leucogohio has hitherto included one species from 

 Corea, two from Western China and four from Japan. Of these 

 the Chinese L. tceniatus Gthr., 1896, and the Japanese L. guentheri 

 Ishikawa, 1901, are very similar to L. strigatus, but differ from 

 it in coloration and in having more scales in a transvei^se series. 



5. AcANTHOGOBio LONGiRosTRis, sp. n. (Plate III. fig. 3.) 

 Depth of body 4|- in the length, length of head 3|-. Snout 



long, decurved, 1|- as long as eye, the diameter of which is 3|- in 

 the length of head and equal to the width of the flat interorbital 

 area. Mouth small, inferior, horseshoe-shaped ; barbel shorter 

 than the eye. Dorsal II 7 ; origin equidistant from tip of snout 

 and base of caudal. Anal 8, with 6 branched rays. Pectoral 

 nearly reaching the ventrals, which are inserted below the 

 anterior rays of the doi'sal. 43 scales in a longitudinal series, 

 5^ in a transverse series from origin of dorsal to lateral line, 

 3^ between lateral line and base of ventral. Silvery, back darker ; 

 blackish spots on the back and on the sides above the lateral line ; 

 small dark spots on dorsal and caudal. 



A single specimen, 95 mm. in total length, from Chong-ju. 



The pharyngeal teeth appear to be in two series (5 . 2 — 2 . 5) ; 

 but this species is not very remote from Hemibarhus barbus 

 Schleg., and it seems to me that the genus Acanthogobio Herz., 

 1892, is scarcely worth recognition, as it differs from Hemibarbus 

 only in having the pharyngeal teeth in 2 series instead of 3. 



6. ACANTHORHODEUS GRACILIS, Sp. n. (Plate II. fig. 1.) 



Depth of body 2|- to 2|- in the length, length of head 4|. 

 Snout a little shorter than eye, the diameter of which is 3 to 3j 

 in the length of head ; interorbital w^idth 2^ in the length of 

 head. Mouth small; no barbels. Dorsal II 13; second spine 

 nearly ^ the length of head, considerably shoi-ter than the longest 

 soft rays, which are nearly as long as the head ; fin highest 

 anteriorly; free edge slightly convex. Anal II 10; second spine 

 ^ or a little more than | the length of head ; free edge slightly 

 concave. Pectoral nearly reaching the ventrals, which extend 

 nearly to the anal. 34 scales in a longitudinal series, 6 or 7 in a 

 transverse series from origin of dorsal to lateral line, 5 or 6 

 between lateral line and base of ventral. Silvery, back olivaceous ; 

 a bluish lateral stripe on the posterior part of the body ; dorsal 

 with alternating series of pale and dark spots on the rays ; anal 

 with a narrow blackish edge. 



Two specimens, 65 and 70 mm. in total length, from Chong-ju.
