 All paratypes with same collecting data as holotj'pe.

 rakers 4 + 1 + 10 (3 to 5 + 1+9 to 11, modally 4 + 1 + 10) (17 specimens). 



Each of the following measm'ements is given as a percentage of

 4.7); least depth of caudal peduncle 12.4 (11.6 to 12.7); length of 

 caudal peduncle 14.5 (14.3 to 14.9); snout to origin of dorsal fin 30.9 

 (29.5 to 31.7); snout to origin of anal fin 65.2 (63.2 to 65.4); snout to 

 origin of pehdc fin 41.0 (40.3 to 43.5); length of dorsal fin base 59.0 

 (58.1 to 59.7); length of anal fm base 17.7 (16.2 to 17.5); length of 

 pectoral fui 34.2 (34.4 to 37.7); length of pelvic fin 23.1 (21.6 to 

 22.9); length of pelvic spine 16.8 (14.4 to 16.7); length of fh-st dorsal 

 spine 7.7 (6.5 to 7.8); length of longest (the fourth or fifth) dorsal 

 spine 18.7 (17.5 to 18.5); length of tenth dorsal spine 13.9 (13.5 to 

 14.3); length of first dorsal soft ray 24.0 (21.1 to 24.2); length of last 

 dorsal ray 12.0 (11.4 to 12.4); length of first anal spine 10.3 (9.9 to 

 11.7); length of second anal spine 21.8 (20.5 to 22.6); length of third 

 anal spine 16.6 (14.4 to 17.7); length of fii'st anal soft ray 22.4 (18.0 

 to 21.0); length of last anal ray 15.3 (13.5 to 15.6); length of caudal 

 fin 24.8 (24.4 to 26.9). 



In addition to those of the family and genus, the following charac- 

 ters apply to this species: profile of head, excluding eye, with a marked 

 indentation above eye; maxillary nearly reaching a vertical at front 

 edge of e3"e; interorbital space markedly concave, scaled only aiite- 

 rioii}", the scaled region extending to space between anterior nostrils; 

 preorbital not scaled, its hind margin free for about half the distance 

 from lower edge to eye and rarely bearing a few serrations (only 2 of 

 17 specimens showed distinct serrations on the lower hind edge of the 

 preorbital); margin of preopercle smoothly curved, all but anterior 

 most part with from 11 to 19 (more on larger specimens) coarse, 

 spinelike serrations (18 on holotype on one side and 19 on the other); 

 suprascapula with 4 to 7 coarse serrations (6 on holotype); 4 rows of
