fin base 31.7 (33.7); longest ray of anal fin 17.7 (17.8); longest ray of 
dorsal 21.5 (22.8); longest ray of pectoral 22.0 (25.0); longest ray of 
pelvics 16.5 (17.4); longest ray of upper lobe of caudal fin 29.9 (33.3);

The following counts were made, respectively: Dorsal rays ii, 8 
(ii, 8); anal ii, 22 (ai, 21); pectoral i, 10-1, 10 (i, 11-4, 11); pelvic i, 
7H, 7 (i, 71, 7); branched caudal rays 17 (17); number of gill rakers 
on first gill arch — — (6+10); scales from upper edge of gill opening to 
midcaudal fin base 37 (37); scales above lateral line 6 (6) and below 
it to pelvic insertion 4 (4); scales in front of dorsal 12 (14) and along 
one side of the supraoccipital process 2 (2); number of teeth in outer 
row of premaxillary 5-5 (5-4) and in the inner row 4-4 (4-4); teeth 
on maxillary 2-2 (4-4). See table 24 for additional counts. 
Body compressed, its depth 2.7 to 2.9, head 3.5 to 3.8 in standard 
length; snout 1% in eye and about 4 in head; interorbital about equal 
to eye and 3 in head; dorsal and ventral profiles about equally arched; 
predorsal and preventral areas rounded, normally scaled; supraoccipital 
process short, its length contained 5% to 6}, times in distance from tip 
to dorsal origin; snout blunt, the lower jaw a little included so that 
when mouth is closed the outer row of teeth on the premaxillary 
show; mouth when closed a little above lower edge of pupil; rear tip 
of maxillary not quite extending to a vertical through front edge of 
pupil; ventral margin of second suborbital meeting preopercle; lateral 
line complete, decurved anteriorly; gill rakers short, pointed, some- 
times a few of those on the lower part of the arch branched; teeth all 
3- to 5-pointed, the middle denticle longest and strongest; anal origin 
usually under the second or third, from the last dorsal ray; adipose 
origin about over the fifth from last anal ray; dorsal origin a little 
closer to midcaudal fin base than tip of snout; pelvic insertion a trifle 
closer to base of last anal ray than to tip of snout; the first branched 
rays of all finsilongest; caudal fin forked; the distal margin of anal fin 
truncate or a trifle concave, and that of dorsal a little rounded; the 
pectorals reaching a little past pelvic insertions and the pelvic fins 
reach almost to the anal origin; intestine with one main loop; about 
7 or 8 pyloric caeca; scales on basal part of caudal fin extend out a 
little over one-third the length of that fin; no pouch on caudal fin. 
Coloration.—In alcohol there is a black line along midaxis of body 
from. behind the vertically elongate humeral spot to midcaudal fin base, 
where it ends in a blackish caudal spot, the latter diffusing on middle 
caudal fin rays and usually not quite reaching the distal margin of the
