 interorbital 3; D.xg; A.iii 7; P. 16; V.i 5. Scales 3-44-12. Teeth 

 minute, no canines. Inferior orbital with a spine direcfted back- 

 wards under the pupil — usually 2 or 3 smaller spines below it. 

 Posterior margins of the opercles toothed. Body oblong, slightly 

 compressed. Branchiostegals 5. Pseudobranchiae developed. Gill- 

 rakers short and blunt, 8 on lower limb. Fins : Caudal forked, the

 14 rows of scales in front of dorsal fin. Color in spirits : Grayish 

 above (in life the upper coloring is greenish) , whitish below the axis. 

 A more or less indistinct white line from snout to first dorsal spine. 

 Two distinct white lines from above the orbit to sixth and seventh 

 rays of soft dorsal. A third white line wider anteriorly, and more 

 or less broken, extends from upper third of 63'e to just posterior of 

 the hind margin of the dorsal fin. A fourth line forms the lower 

 boundary to the gray coloring along the median line from eye to 

 caudal. The upper half of pedlorals has a dusky blotch, and there 

 may be a dusky blotch, in some specimens, on the sides half way 

 between the axis of body and the belh\ Fins: All yellowish white,

 Caudal slightly emarginate. Pecftorals equal to distance from pos-

2 I have carefully compared this fish with Quoy & Gainiard's description and figure (Quoj' 

 & Gaim. Voy. Freyc. Poiss., p. 322, pi. 60, fig. 3) and am convinced the species should .stand as 

 .S. lineafiii, Quoy & Gaim.
