 anal fin; gill rakers 4 + 1 + 12 (4 or 5 + 1 + 12 or 13) (9 specimens). 



Each of the following measurements is given as a percentage of the 

 standard length; measiu-ements of paratypes are based on 4 specimens, 

 94.5, 80.4, 66.7, and 51.5 mm. in standard length: greatest depth of 

 body 38.9 (38.1 to 39.9); width of body at gill opening 16.8 (14.8 to 

 16.9); head length 37.0 (36.5 to 39.1); snout length 12.0 (10.6 to 13.0); 

 eye diameter 7.2 (7.4 to 9.7); postorbital length of head 20.6 (19.3 to 

 22.2); bony interorbital space 5.3 (5.1 to 5.4); least depth of caudal 

 peduncle 13.0 (13.2 to 14.2); length of caudal peduncle 14.5 (14.0 to 

 15.2); snout to origin of dorsal fin 40.1 (38.6 to 40.5); snout to origin 

 of anal fin 66.4 (65.8 to 69.8); snout to origin of pelvic fin 44.2 (43.0 

 to 47.3); length of dorsal fin base 53.8 (52.0 to 54.0); length of anal fin 

 base 18.0 (18.5 to 18.9); length of pectoral fin 22.1 (22.5 to 24.9); 

 length of pelvic fin 18.5 (20.1 to 22.2); length of pelvic spine 11.3 (11.7 

 to 11.8); length of first dorsal spine 5.5 (5.8 to 6.3); length of third 

 (longest) dorsal spine 12.1 (12.6 to 14.5); length of tenth dorsal spine 

 8.6 (8.4 to 8.6); length of first dorsal soft ray 18.5 (18.0 to 19.4); length 

 of last dorsal ray 10.7 (11.2 to 12.0); length of first anal spine 8.4 (8.7 

 to 9.7); length of second anal spine 12.3 (13.6 to 16.5); length of third 

 anal spine 11.7 (12.8 to 14.9); length of first anal soft ray 17.8 (18.2 to 

 20.6); length of last anal ray 13.5 (14.7 to 15.6); length of caudal fin 

 20.1 (20.7 to 24.1). 



In addition to those of the family and genus, the following characters 

 apply to this species: interorbital slightly concave with a median band 

 of small scales about one-half total width of bony interorbital space; 

 small scales middorsally on snout extend forward to anterior nostrils; 

 a few small embedded scales on preorbital; 6 straight rows of large 

 scales on cheek; large scales on cheek and opercle with small basal 

 scales; large-scaled areas on cheek and opercle bordered by small 

 scales; interopercle covered with small scales; 10 rows of scales above 

 lateral line on caudal peduncle on one side to lateral line on other; 

 about 12 median predorsal scales; small scales basally on fins; maxillary 

 extending to or beyond a vertical through hind edge of pupil; upper 

 middle part of free margin of preopercle with a few tiny serrations; 

 margin of preopercle rounded with no marked concave indentation; 

 pelvic fin tips reach to or slightly beyond anus, but not to origin of 

 anal fin; first dorsal ray slightly extended; second and third of the lower 

 7 unbranched pectoral rays the longest; caudal fin truncate; hind flap 

 on anterior nostril with about 9 to 17 cirri (17 on holotype). 



Color in alcohol light yellowish brown, a little darker dorsally, some 

 specimens with about 3 broad bars faintly visible on back; a pale-edged, 

 slightly irregular black mark about as long as eye extending diagonally 

 upward from rear center of eye; fins pale yellowsh, the posterior part
