NO. 1714. JAPANESE SEA BASS.^JORDAN AND RICHARDSON. 429 



Specimens from Hongkong have the back shghtly less elevated 

 and the depth less and the opercular spines on the average a little 

 longer and more slender. Probably all belong to one species. 



(bis, two; fascia, band.) 



3. Genus LATEOLABRAX Bleeker. 



Lateolabrax Bleeker, Nieuwe Nalez., Japan, 1857, p. 53 (japonicus). — Boulen- 



GER, Cat. Fishes, vol. 1, 1895, p. 122. 

 Percalabrax Gunther, Cat. Fishes, vol. 1, 1859, p. 70 (japonicus). (After Perca- 



labrax « of Temminck and Schlegel.) 



Body compressed, elongate; mouth large, protractile; maxillary 

 with supplemental bone; villiform teeth in jaws and on vomer and 

 palatines; tongue smooth; no canines; preopercle serrated behind, 

 its lower border with a few strong antrorse spines; opercle with a 

 single spine; gill rakers long and slender; seven branchiostegals ; 

 scales small, ctenoid; head, except jaws and chin, scaled; lateral line 

 complete, the tube straight, extending nearly the length of the scale; 

 two dorsals, connected at the base, anterior with 11 or 12 strong 

 spines; anal III, 8 or 9; caudal emarginate; ventrals behind base 

 of pectorals, close together, with a strong spine; pectorals obtusely 

 pointed. "Posterior processes of premaxillaries not extending to 

 frontals; parietal and supraoccipital bones not extending to between 

 post-frontal processes; supraoccipital and parietal crests strong, not 

 produced on the frontal; vertebraB 35 (17 + 18)." (Boulenger.) 



Coasts of China and Japan; one species. The genus is allied to 

 the bass (Dicentrarchus) of Europe, and to the American genera 

 Morone and Roccus.

a We follow Gill and Boulenger in retaining for this genus the name Lateolabrax 

 instead of the earlier term, Perca-labrax, used by Temminck and Schlegel. It is 

 evident that the Fauna Japonica used the name Perca-labrax japonicus as the equiv- 

 alent of Perca (Labrax) Japonicus suggested by Cuvier and Valenciennes. Temminck 

 and Schlegel use the French name "Bars" as the equivalent of Perca-labrax. The 

 "Bars" comprise Cuvier's subgenus Labrax, or, as suggested in a footnote, his Perca 

 (Labrax). Evidently in the Fauna Japonica the hyphen replaces the bracket. As 

 the type of the "Bars" is the European, Perca labrax, the name Perca-labrax has the 

 same type. If regarded as tenable, Perca-labrax might replace Dicentrarchus for the 

 species now called Dicentrarchus labrax.
