them on caudal iieduncle; a row of 9 round black spots on each side at 
base of dorsal fin, the first one smallest, opposite membrane of first spine, 
the other 8 separated somewhat obscurely into jiairs, the first pair under 
middle spines, second under last spines, third under first rays, fourth 
under last rays; 2 or 3 very small black dots on upper edge of caudal 
peduncle; 2 or 3 more in front of dorsal on median line, each accompanied 
by a similar one on either side; in some specimens a few scattering ones 
on top of head behind eyes, sometimes regularly arranged ; a few dark- 
brown spots behind eye; various dark markings on side of head, without 
very definite pattern, but usually 2 oblique stripes on cheek, a heavy 
black blotch on interopercle and 2 on the r^unus of the mandible, which, 
with their fellows of the other side, make distinct crossbars on lower side 
of head usually extending across maxillary ; chin and lower part of opercle 
with dark si)ots; lateral line white, with a few broken spots, compara- 
tively faint, just below it; iris red, with an inner ring of white surround- 
ing the pupil ; spinous dorsal pale, the edge of the membrane black, this 
color bordered below with faint yellow ; soft dorsal pale, spotted through- 
out with light orange, with a marginal band of the same, outside of which 
is a very narrow pale-blue edge; ventral very pale blue, the produced 
ray somewhat yellow; anal pale blue with some light orange on last rays; 
pectoral and caudal uniform pale reddish, unmarked. 
In spirits all the red and yellotv markings disappear, the dark persists, 
and additional markings are brought out as follows: Along the anterior 
and upper part of trunk and crossing the lateral line are dark-brown 
vertical bars, diifuse and running together, or separated and broken into 
round or quadrate blotches; in the middle part of the course of the yellow 
longitudinal band appears a row of very small black points; spots on soft 
dorsal dusky; dark mottlings on caudal; upper and lower base of pec- 
toral, and sometimes axil, dusky.
