snout to anal origin 65.2 (66.0); snout to pectoral insertion 27.8 (27.5); 
snout to pelvic insertion 47.8 (49.6); distance from dorsal origin to 
midcaudal fin base 53.0 (52.3); dorsal origin to tip of adipose fin 41.0

The following counts were made, respectively: Dorsal rays 11, 9 (11, 9); 
anal iii, 17 (iii, 21); pectoral i, 13-1, 18 (G@, 12-1, 12); pelvic i, 71, 7 
(i, 7-1, 7); branched caudal rays 17 (17); number of scale rows from 
upper edge of gill opening to midcaudal base 31 (81); scales from origin 
of dorsal fin to last pore of lateral line 5 (5), and from pelvic base to 
last pore of lateral line 4 (4) ;scales in front of dorsal fin along middorsal 
line 10 (10); number of scales along one side of supraoccipital process 
2% (3). All the counts made for this new species are summarized in

length; lower profile of body a little more arched than dorsal profile; 
snout rounded, short, about 1.6 to 1.8 in eye, 4.5 in head; eye 3 in 
head and about equal to width of convex interorbital space; second 
suborbital covering cheek, without naked area behind and below where 
it joins the preopercle; adipose fin present; lateral line incomplete, 
of 9 or 10 pores; supraoccipital process short, usually bordered by 
about 2% scales on each side; a large fontanel from between eyes to 
tip of supraoccipital process; mouth terminal oblique, lower jaw equal 
to upper or extending a trifle in front of snout tip and when closed 
mouth on level of middle of pupil; dorsal origin about equidistant 
between snout tip and midcaudal fin base; pelvic insertions in front 
of a vertical line through dorsal origin; anal origin usually a trifle 
bebind a vertical line through base of last dorsal ray; adipose origin 
usually over base of second or third from last anal rays; anal origin an
