SPECIMENS STUDIED 



Bikini Atoll: 3 stations, 8 specimens, 36 to 67 mm. in standard length. 

 Rongerik Atoll: 3 stations, 10 specimens, 30 to 72 mm. 



Description. — Dorsal JBn rays X,16 or 17 (rarely XI, 15); anal 11,13 

 or 14; pectoral ii,17 (rarely ii,18); scale rows from upper edge of gill 

 opening to base of caudal rays 47 to 54 (usually 49 to 51), from base 

 of dorsal to lateral line 4K plus 2 on sheath, from lateral line to origin 

 of anal 20 to 22; gill rakers 5 + 1-}- 13. 



Depth of body 1.7 to 1.9; head 3.0 to 3.2; both in standard length. 

 Snout 2.7 to 4.3; eye 2.5 to 3.8; preorbital width 5.3 to 9.4; length of 

 upper jaw 2.7 to 3.0; postorbital part of head 2.6 to 2.8; interorbital 

 width 2.9 to 3.0; depth of caudal peduncle 1.8 to 1.9; length of pectoral 

 fin 1.1 to 1.2; of pelvic fins 1.0 to 1.2, of second or third dorsal spines 

 2.2 to 2.5, of middle caudal rays 0.9G to 1.15; all in length of head 

 (tip of snout to tip of longest opercular spine). Depth of caudal 

 peduncle in its length 0.9 to 1.2; angle of snout profile with lengthwise 

 axis of body 53 to 60 degrees, snout profile convex. 



Body deepest between origin of dorsal and insertion of pelvic fins; 

 preorbital, suborbital, and preopercle all serrate, opercle and sub- 

 opercle with strong radiating spines; interopercle with spines only in 

 posterior angle; spines of dorsal fin subequal, fin not deeply notched, 

 soft dorsal and anal somewhat pointed at angle, caudal truncate, its 

 outer angles rounded; scales on top of head occur forward to middle 

 of interorbital area. 



Color in alcohol. — Lips and chin yellowish or light brown, nape and 

 interorbital area usually darker brown; a broad white band, slightly 

 wider than eye diameter, extending from origin of spiny dorsal across 

 anterior part of opercle and posterior part of preopercle to posterior 

 part of interopercle, this band narrowly bordered by black; breast
