Description. Based on the holotype and paratypes. Detailed 
measurements, expressed in hundredths of the standard length, were 
made on the holotype and one paratype as recorded below, first for 
the holotype, then for the paratype in parentheses. Standard length 
in mm. 258 and 222. | 
Length of head 23.6 (24.0); greatest depth of body 23.0 (22.8); 
length of snout 9.00 (9.01); greatest width of head 13.6 (12.6); diam- 
eter of eye or between eyelids along anterior-posterior axis 4.38 
(4.46); interorbital space 11.4 (11.9); postorbital length of head 12.0 
(12.3); eye to posterior nostril 2.67 (2.48); length of caudal peduncle 
12.0 (11.9); least depth of caudal peduncle 9.97 (9.65); distance from 
snout to dorsal origin 41.8 (41.1); snout to anal origin 83.4 (82.0); 
snout to adipose origin 86.0 (84.7); snout to pectoral insertion 22.2 
(23.1); snout to pelvic insertion 45.3 (46.0); length of base of dorsal 
14.7 (13.8); length of anal base 8.02 (8.07); longest ray of dorsal fin 
21.9 (19.6); longest ray of anal 15.3 (13.9); longest ray of pectorals 
15.2 (14.6); longest ray of pelvics 17.1 (16.0); longest ray of caudal 
fin 25.2 (22.8); shortest caudal fin rays 9.69 (8.10). 
The following counts were made on the holotype and paratype, re- 
spectively: Dorsal rays ii, 10 (ii, 10); anal ii, 8 (ii, 8); pectoral i, 15-1, 
15 (Gi, 15+, 15); pelvic i, 8-1, 8 G, 8-1, 8); scales 42 (43) from upper end 
of gill opening to base of midcaudal fin rays; scales from dorsal fin 
origin to lateral line posteriorly downward 5% (5%): scales from anal 
origin to lateral line (backward and upward) 5 (5); scales before dorsal 
fin 13 (13); zigzag scales around caudal peduncle 16 (16); scales from 
dorsal base to adipose origin 16 (16). For additional counts see table 8.
