orbital portion of the head, and one half of the width of the 
interorbital space. Mouth subhorizontal, wide, the maxillary 
extending to below the middle of the eye. The chain of 
infraorbital bones is very narrow. Suboperculum narrow 
and long. The anterior dorsal ray is somewhat nearer to the 
root of the caudal fin than to the end of the snout and imme- 
diately behind the root of the caudal. Origin of the anal fin 
at a distance behind the end of the dorsal. Caudal fin strong, 
broad, long, and deeply cleft. The length of the pectoral 
equals that of the postorbital portion of the head. Scales 
distinctly radiated ; there are six series between the lateral 
line and the root of the ventral fin. The lateral line descends 
above the pectoral fin gradually to below the median line of 
the side, runs along the lower half of the tail, but terminates 
in the middle of the root of the caudal. Coloration uniform 
silvery. 
Mr. Styan collected specimens in the main stream and one 
young one in mountain-streams near Kiu-Kiang. The largest 
is 4 feet long.
