FAMILY LABRIDAE — SCHULTZ 157 



cheek and behind eye, dorsal side of head naked; body scaled, but 

 scales along bases of dorsal and anal fins scarcely forming a sheath; 

 pectoral fin reaches to opposite sixth lateral line scale ; second branched 

 pectoral ray longest; pelvics not quite reaching to anus; rear mar- 

 gins of median fins rounded, that of caudal fin truncate, outer rays 

 of caudal fin of adults becoming elongate and projecting somewhat. 



Color in alcohol. — Background coloration brownish dorsally, paler 

 ventrally; dorsal surface of head with round or oblong white spots; 

 3 or 4 white streaks in front of eye and an equal number behind eye, 

 these streaks parallel with each other, and a single white streak just 

 below eye; on lower half of head and extending at right angles to the 

 white streaks are 8 or 9 parallel black streaks, the first from corner 

 of mouth to isthmus but none extend on isthmus; outer caudal rays 

 dark brown, middle caudal rays pale; dorsal fin dusky except distal 

 part of soft rays white; anal, pectoral, and pelvics pale. 



Color when alive. — The dark streaks are blue, white streaks red; 

 caudal fin greenish; paired fins yellowish. 



Remarks. — This well-marked species was rare on the reefs and in 

 the lagoon where we fished. It may prefer deeper water since 2 of 

 our specimens were caught on hook and Une at a depth of nearly 100 

 feet in Bikini lagoon.
