 head 20.5 (20.7); bony interorbital space 5.6 (5.8); least depth of 

 caudal peduncle 12.9 (13.2); length of caudal peduncle 15.1 (14.9); 

 snout to origin of dorsal fin 40.7 (40.5); snout to origin of anal fin 

 69.5 (70.2); snout to origin of pelvic fin 45.7 (42.0); length of dorsal 

 fin base 53.5 (51.3); length of anal fin base 18.1 (19.0); length of 

 pectoral fin 24.1 (23.1); length of pelvic fin 20.4 (20.6); length of 

 pelvic spine 12.9 (13.5); length of first dorsal spine 6.8 (7.1); length of 

 third (longest) dorsal spine 14.7 (14.5); length of tenth dorsal spine 

 8.8 (7.1); length of first dorsal soft ray 17.9 (18.1); length of last 

 dorsal ray 11.0 (11.2); length of first anal spine 8.9 (8.7); length of 

 second anal spine 15.2 (14.7); length of third anal spine 12.9 (12.4); 

 length of first anal soft ray 18.8 (18.3); length of last anal ray 13.3 

 (14.0); length of caudal fin 21.1 (21.0). 



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 to two-thirds the total width of 

 bony interorbital space; small scales middorsally on snout extend 

 forward to anterior nostrils; preorbital scaled, especially posteriorly; 

 a small patch of scales on side of snout just below and slightly anterior 

 to anterior nostril; 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 to 11 rows of scales above lateral line on 

 caudal peduncle on one side to lateral line on other; about 1 1 median 

 predorsal scales; small scales basally on fins; maxillary reaching past 

 center of eye but not posterior to a vertical at hind edge of pupil; 

 about upper two-fifths of free margin of preopercle finely serrate; 

 preopercular margin rounded with no concave indentation; pelvic fin 

 tips reaching anus; first dorsal soft ray very slightly longer than 

 second; thh-d of the lower 7 unbranched pectoral rays the longest; 

 caudal fin truncate; hind flap on anterior nostril with 10 cutI. 



Color in alcohol dark brown, the caudal peduncle and ventral part 

 of abdomen and body just above base of anal fin pale yellowish (brown
