them on caudal peduncle; 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 pairs, 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 ram us 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 spots; 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 baud 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 yellow 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, diffuse 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.
