JORDAN AND MEIZ: FISHES KNOWN FROM THE WATERS OF KOREA 31 



projecting; outline of back arched, descending abruptly under last three rays 

 of soft dorsal; caudal peduncle deeper than long, tapering very little; ventral 

 outline almost straight from snout to anal. 



Spinous dorsal low, gently and evenly rounded from tip to tip; longest 

 spine 3 in head; soft dorsal rounded, slightly higher than spinous dorsal, its 

 base one-half that of the latter; caudal rounded; anal short, rounded, as high 

 as soft dorsal; second spine longer and much stronger than longest dorsal spine; 

 ventrals as long as pectorals, not nearly reaching vent; pectorals narrow. 

 Maxillary reaching posterior margin of eye; preopercle with numerous small 

 spines above, two larger ones at angle, and two on margin below; opercle with 

 two broad, flat spines above; interorbital area slightly concave, smooth; body 

 covered with very small ctenoid scales in uniform series; cheeks, opercles, and 

 temporal region with small embedded scales; remainder of head naked; fins not 

 scaled, except caudal base. 



Color in spirits light brown, sides below lateral line with large round or 

 ovate dark spots, separated by narrow, light, undulating streaks, forming rings 

 around the spots. Above the lateral line the spots are smaller and more 

 separated. Indistinct dark blotches are evident on back below middle of spin- 

 ous dorsal, and below front of soft dorsal, and on caudal peduncle below last 

 dorsal ray. Head above dark, with small, round, black spots; cheeks and 

 opercles and all fins, except pectorals, spotted like upper part of sides; throat 

 and belly white; spinous dorsal margined with black. 



This species agrees fairly well with the description of Siniperca scherzeri 

 Steindachner from the lower Yangtse River. It differs in the number of fin- 

 rays (Dorsal XIII, 11 or 12 in Siniperca scherzeri), in the sharper and longer 

 snout, and in the sharper coloration. It is probable that Steindachner's figure 

 was taken from an older fish than the one here figured, but of the same species.
