 Kwajalein Atoll: 1 station, 1 specimen, 67 mm. 



Description. — Dorsal rays X,12; anal 111,8; pectoral i,8,v; pelvic 

 1,5; branched caudal fin rays 7+6; vertical scale rows from upper 

 edge of gill opening to midbase of caudal fin 37 to 39, with 3K or 4 

 scales from dorsal origin to lateral line, and 8 or 9 scales from anal 

 origin to lateral line; 4 rows of enlarged scales on cheek; gill rakers 

 3 or 4+1 + 10 or 11. 



Greatest depth 2.7 to 3.2 ; head 2.5 to 2.8 ; length of longest branched 

 pectoral ray 4.0 to 4.7; longest lower simple pectoral ray 2.8 to 3.2; 

 all in the standard length. Snout 3.2 to 3.6, eye 3.8 to 4.6, snout tip 

 to rear of maxillary 2.9 to 3.0, greatest depth 1.1 to 1.3; least depth of 

 caudal peduncle, 3.0; postorbital length of head 1.9 to 2.1; all in 

 length of head. Least depth of caudal peduncle in its length 1.9. 

 Bony interorbital 1.3 to 2.2 in eye. 



Greatest depth opposite front part of dorsal base; profile of head 

 pointed; gill meuibranes broadly joined across isthmus, free, covered 

 v/ith scales; maxillary concealed by preorbital anteriorly; lips thick, 

 broad, lower lip at tip with a deep incision; upper lip deeply incised 

 each side of its anterior tip; lower jaw equal to upper, or nearly so; 

 when mouth is closed, tlie latter a little oblique; cheeks with 4 rows 

 of enlarged scales, these bordered around orbit by some much smaller 

 scales; mandibles with small scales; nostrils separated by a dermal 

 isthmus, posterior margin of anterior one bearing a tuft of dermal 

 cirri; behind tips of each dorsal spine occm* a tuft of cirri; accessory 

 pelvic scale very short; scales cycloid; interorbital and posterior part 

 of preorbital scaled; vomerine teeth villiform in a V-shaped narrow 

 band; probably no teeth on palatines or a very few minute ones at 

 head of bone; a band of villiform teeth in upper jaw very broad 

 anteriorly, becoming narrow posteriorly, bordered on the outside by 

 a row of short conical teeth; lower teeth similar, except they become 

 iiniserial posteriorly; pelvic insertion behind pectoral base, about 

 opposite base of fourth dorsal spine; basally all fins scaled; first lower 

 simple pectoral ray longest; rear margin of caudal fin truncate; pre- 

 opercular margin somewhat coarsely denticulate; interorbital space a 

 little concave; lateral line complete. 



Color in alcohol. — Background color pale or whitish, with about 10 

 brown bars separated by pale interspaces narrower than brown bars; 

 these dark bars extending on scaled part of dorsal fin; opercle with a 

 large dark brown ocellate spot; another dark brown ocellate spot in 

 fourth-from-last dark bar, extending from lateral line on rear of base 

 of soft dorsal fin; head with brown streaks; pectoral, pelvic, and
