NO. 1493. FISHES FROM PORT ARTHUR— JORDAN AND STARKS. 517 



Family SERRANID^. 



10. LATEOLABRAX JAPONICUS (Cuvier and Valenciennes). 



Several .small sj^ecimens collected, the largest 16 cm. in length. 

 They differ from specimens from Japan in being generally darker and 

 in having the spots on body larger and much more conspicuous. In 

 the Japanese specimens the spots are more scattered, comparatively 

 faint or sometimes almost wholly absent. No other differences are 

 appreciable. A large specimen from Port Arthur, 55 cm. long, has no 

 spots on the body but several rows of spots on the membrane of the 

 dorsal (the small ones have 2 or 3 rows). Specimens from Japan of 

 various sizes show this character to be variable, though the larger 

 specimens usually have the dorsal spots more numerous.

Head 3| in length to caudal base; depth 2^. Eye 4 in head, 1| in 

 snout. Snout 2i in head; interorbital space 3|; maxillary 2|. Dor- 

 sal rays, XII, 10; anal, III, 8; scales 57. 



Upper anterior profile from front of dorsal to tip of snout a mod- 

 erate even curve with a scarcely distinguishable protuberance in front 

 of e\'e. Lower jaw slightly included, its tip not square, but rounded 

 to a blunt point at base of teeth. Maxillary reaching to below front 

 of pupil. Two large canines on each side of front of upper jaw; 3 on 

 lower, growing smaller anteriorh'; behind these a couple of rows of 

 very small conical teeth; a single molar on posterior end of lower jaw 

 in front of which are 2 rows of similar teeth, giving place in front 

 to the fine conical teeth behind canines; 7 teeth in the outer row, 

 the third from the front slightly longer and sharper than the others; 

 4 large molars on inner row with smaller molars in front, which pass 

 gradually into the small conical teeth; 7 molars in outer row on upper 

 jaw growing conical anteriorly and giving place abruptly to the small 

 conical teeth; 3 or 4 large molars on inner row posteriorly, changing 

 abruptly at about middle of side of jaw to very small teeth. Preor- 

 bital at end of maxillary equal in wddth to the vertical diameter of 

 •eye. Gill rakers short and rather sharp posteriorly, the front ones 

 blunt; the longest equal to half diameter of pupil; 9 developed on 

 lower limb of arch.
