530 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.40. 



inward and backward; jaw covered with a band of fine teeth. Pseu- 

 dobranchise large; gillrakers extremely long and slender, the ventral 

 ones equal to diameter of eye; 11-24 on the first arch. 



Curves of lateral line rather closely following the dorsal contour, 

 and not abruptly bent at any point. Scales of body ctenoid; 6 rows 

 above lateral line at its origin; 2.5 rows between lateral line and 

 middle of spinous dorsal; 3.5 between lateral line and middle of soft 

 dorsal; 14 between base of anal and lateral line. 



The dorsal spines beyond the third are of about equal length, 3 

 times in head; rays about 1.9 in head, the last ones somewhat fila- 

 mentous; base of soft dorsal with a low sheath of scales. Second and 

 third anal spines contained 2.3 in head, the first not half as long; 

 middle rays of fin slightly longer than head. Tips of both dorsal and 

 anal extend beyond base of caudal. Caudal lunate, the upper and 

 lower rays elongate and filamentous; extreme length of fin contained 

 2.5 in distance from tip of snout to base of caudal. Ventral acutely 

 pointed; equal in length to caudal, reaching somewhat beyond base of 

 third anal spine. Pectoral almost equal in length to head. 



Color in the preservative pinkish with a bluish tinge; three yellow- 

 ish, nearly parallel stripes extending from head backward and disap- 

 pearing just before reaching caudal peduncle; a narrow, pearly white 

 stripe extending from tip of snout beneath eye downward to lower 

 edge of base of pectoral; a bow-shaped stripe of same color, though 

 fainter, passing from middle of base of spinous dorsal downward and 

 curving backward along base of anal; median line of abdomen with 

 a dead white stripe; first gill arch with a very narrow, white stripe 

 along base of filaments. 



Type. — Cat. No. 68230, U.S.N.M., a specimen measuring 118 mm., 

 from Kagoshima. 



Family LUTIANID/E. 



PLATYINIUS AMOENUS, new species. 



This form resembles P. macrophtlialmus of the Atlantic. It is 

 somewhat more slender, has a more pointed snout, and differs in 

 color. 



Head 2.2 in the length to base of caudal; depth 2.9; depth caudal 

 peduncle 3.2 -in head; diameter of eye 3; length snout 3.2; width 

 interorbital space 4.8; length maxillary 2.6; D. X, 11; A. Ill, 8; 

 scales lateral line 62; between lateral line and origin of spinous dorsal 

 6; between lateral line and origin of anal 14. 



Dorsal outline rather more strongly curved than the ventral. 

 Eye very large, located before middle of head, high up, the inter- 

 orbital area extending but little above it; maxillary not quite reach- 

 ing a point below middle of eye; interorbital area convex; the skull 

 almost flat, with four ridges, the inner of which are separated by a
