NO. 1714. JAPANESE SEA BASS.— JORDAN AND RICHARDSON. 471 



elevated; profile convex; snout pointed; mouth large, oblique; maxil- 

 lary reaching vertical from back of pupil; lower jaw slightly pro- 

 jecting; a pair of small (fanines in upper and lower jaw at symphysis; 

 a strong backwardly directed canine in each side of lower jaw anterior 

 to its middle; tongue and entopterygoids toothless; nostrils subequal; 

 border of preopercle rounded, finely denticulated; opercle with 3 fiat 

 points; gill-rakers 14, the longest about equal to the corresponding 

 filaments. Scales ciliate, adherent; head entirely scaled, including 

 mandibles, chin, and maxillaries; scaled encroaching on bases of soft 

 fins but not of spinous dorsal; lateral line normally curved, not form- 

 ing an angle under last dorsal rays. Dorsal originating very slightly 

 in front of pectoral; dorsal spines strong, the fourth longest, 2 in head, 

 the spines shortening backward, the last being only about half the 

 height of the soft rays, the second of which is elongated and filamen- 

 tous; caudal weakly emarginate, the upper rays produced, filamen- 

 tous; anal spines strong, the second longest, 2.1 in head; ventrals 

 inserted under pectorals, 1.5 in head; pectorals subsymmetrical, 

 pointed, as long as head, reaching past base of anal. Color yellowish 

 red, probably scarlet in life. 



Of this species we have four specimens, 3 to 4 inches long, dredged 

 in Sagami Bay. It lives in rather deep water.

17. Genus TOSANA SiTiith and Pope. 

 Tosana Smith and Pope, Proc. U. S. Nat. Mus., vol. 31, 1906, p. 470 {niwse). 



Body elongate, moderately compressed, with short, blunt head; 

 dorsal single, without notch, the third spine much the longest, no 

 rays filamentous; caudal crescentic, the lobes produced, upper lobe 

 the longer; anal with the third spine longest; pectoral rays all undi- 

 vided; scales large and strongly toothed, covering all parts of body 

 and head; lateral line high, its tubes simple; no angle at base of 

 caudal peduncle; preopercle with vertical limb evenly serrate, its 

 lower margin entire; opercle with 3 flat spines; jaws with large, prom- 

 inent, projecting canines; outer row of teeth in upper jaw canine- 

 like, inner ones fuie and villiform; teeth in lower jaw canine-like, in 

 a single row; vomer and palatines with villiform teeth ; tongue smooth ; 

 no supplemental maxillary; gill-rakers very long and slender; gill- 

 membranes free from the narrow carinate isthmus. (Smith and 

 Pope.) 



This genus is said by the authors to differ from Pseudanihias 

 Bleeker mainly in the unbranched pectoral rays and larger scales, and 

 from Pronotogrammus Gill in the more posterior insertion of the ven- 

 trals, the closely scaled top of head, absence of preopercular spines, 

 and dentition. It seems to be well separated from both, as also from 

 DactylantMas, which has likewise simple pectoral rays.
