 to 2, upper profile slig^htly concave; eye 63^ to 7 ro> 3 to 3^ in snout, 

 15^ to 2 in interorbital; mouth cleft 4 to 43/^ in head; upper lip

 one, or length % of pupil in adult; interorbital 33^ to 3f^ in head, 

 broadly convex. Gill rakers 7+13, rather firm, short points. 



Scales in lateral line 17 + 5 + 2; 2 scales above lateral line, 7 below, 

 6 to 8 predorsal; cheek with 3 rows of rather small scales, preorbital 

 and preopercle flange naked. Scales with 42 to 48 basal radiating 

 striae, which crowded in each indenture of trilobate edge; apical 12 

 to 20; circuli fine. 



D. IX, 10, I, ninth spine 2% to 2% in head, first ray 2% to 2^4; 

 A. Ill, 9, I, third spine 3}4 to 3%, first ray 2 j-i to 2 J/g; caudal iji 

 to 1%, emarginate; least depth of caudal peduncle 2}4 to 2}^; pec- 

 toral IK to 1%; ventral l^tolj/g. 



Back pale brown, down to 1 scale below and along lateral line, 

 uniform. Sides and below, also posterior and lower side of head, 

 drab; each scale with vertical dusky bar and 1 to several spots of

 olive. Fins dull brown, mostly uniform, lower ones or ventral and 

 anal often neutral blackish. 



Red Sea to the East Indies, Okinawa, and Micronesia. A very 

 handsome species, with unique color pattern. Weber unites Scarus 

 pulchellus Riippell simply as a variant. Our material seems to 

 justify its acceptance as a distinct species.
