Family PRISTOPOMATID^. 



Genus SCOI^OPSIS Cuvikk & Valenciennes. 



56-59. Scolopsis lineatus' Quoy & Gaim. Sihig-. 



Head 3.20; depth 3; eye 3; snout 3.20; mandible equal to eye; 

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

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

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

 Posterior margins of the opercles toothed. Bod}^ oblong, slightly 

 compressed. Branchiostegals 5. Pseudobranchiae developed. Gill- 

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

 upper lobe the longest. Ventrals and pedlorals of about equal 

 length, 1 .20 into head. Base of anal 3.50 into base of dorsal. About 

 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 eye to just posterior of 

 the hind margin of the dorsal fin. A fourth line forms the low'er 

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

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

 ma}' be a dusky blotch, in some specimens, on the sides half way 

 between the axis of body and the belly. Fins: All yellowish white, 

 the spines with a bluish wash ; no dark spot between first and third 

 dorsal .spines. Four specimens. Length 6-7.50 inches. Guam,

 Width of mouth is 2.66 Lips rather narrow^ the upper lip one-

 fir.st dorsal spine. No lateral line. No true teeth in jaws. Fins: 

 Caudal slightly emarginate. Pecft orals equal to distance from pos- 

 terior of head to anterior nostril. In the specimen before me the 

 pecftorals do not reach quite to the vertical of the origin of dorsal, 

 but to the vertical of the next anterior row of scales. Ventrals and 

 soft dorsal about equal in length, i .50 into head. Spinous dorsal 



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

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

 5'. liiieatus, Quoy & Gaim.
