Figure 19 
Depth 624; head 4, width 1. Snout 214 in head; eye 324, 134 in 
snout; maxillary not quite reaching to eye, entire, length (in profile) 
3 in head; orbit 27%, separated from its fellow only by narrow bony 
ridge; mouth cleft short, lower jaw very slightly shorter and included 
in upper jaw; lips narrow, smooth, entire; teeth fine, minute, villi- 
form, in narrow bands in both jaws. Preopercular spine long as 
orbit, ends in backwardly directed point and along inner edge row 
of about a dozen very fine uniform denticles and small subbasal 
denticle in front pointing forward. 
Lateral line complete, high along side of back, simple, connecting 
intersection on predorsal before first dorsal and two intersections 
rather closely set on caudal peduncle posteriorly a little before caudal 
base. 
D. IV—9, 1, first spine 214 in fish without caudal, third spine 
314, first ray of second dorsal fin 114 in head, last ray 1; A. 8, 1, 
first ray 214, last ray 1149; least depth of caudal peduncle 41%; 
caudal fin nearly long as rest of fish; pectoral 324 in fish without 
caudal, rays 1, 18; ventral rays I, 5, fin length 3 in fish without 
caudal. 
Color in alcohol light brown to pale mauve above, marked with 
very numerous and variable dark rings, arcs, and spots. About 10 
rather large dark brown blotches along each side of back above. All 
under surfaces of body largely white. On head above many dark 
rings, closely set and variable. On head below large black blotch, 
more or less triangular on throat or chest, and on each side extended 
up on prepectoral region many or numerous dark brown parallel 
lines, separated by narrow pale to whitish lines. First dorsal largely 
blackish with numerous more or less longitudinal parallel white lines 
on first half of fin and fusing or giving place to greatly fewer on 
last half of fin. Second dorsal with four dark longitudinal streaks, 
most distinct or darker on fin rays. Anal pale, with broad blackish 
submarginal band. Caudal with 10 dark blotches on upper half of 
fin and broader intervals with dark circles and ares; lower half of 
fin with edge of each ray terminally dark. Pectoral pale. Ventral 
whitish, with five transverse dark bars. 
Known by its very distinctive coloration, the branchiostegal and 
prepectoral region with many parallel close-set longitudinal bands,
