FISHES OF HAWAIIAN ISLANDS. 
457 
cave, with 2 prominent ridges diverging posteriorly and ending in the 2 twin spines of those at anterior 
angles of the occipital depression; dorsal profile of the body much more convex, greatest depth at 
fourth dorsal spine; depth of caudal peduncle equal to eye, 3.5 in greatest depth of body; fourth dorsal 
spine the longest, a little greater than half of head; third and fifth spines equal, but little shorter 
than fourth; second 1.5 in third, first 1.75 in second; spines back of fourth regularly decreasing in length 
to next to last, which is 2 in fourth; last longer, equaling second; soft pays abruptly longer than last dorsal 
spines, second, third, and fourth longest, equaling longest spine; last soft rays equal to next to last 
spine; second anal spine longest and much thicker than others, 1.75 in head; first slender, 2 in second; 
third slender, 0.8 of second; first and second soft rays longest, 1.6 in head; caudal slightly rounded; 
pectoral round, middle rays longest; ventral rounded, second ray longest, its spine equal to sixth dorsal 
spine; head and fins naked. 
Characters very constant. In smaller specimens the posterior spines of orbital rim not so evident 
as in type and in most the humeral spine smaller. Size of supraorbital tentacle varies much, in some 
very small or absent, in others very large, fringed, length greater than eye, equal to second dorsal spine. 
Color of fresh specimen (field No. 223), whitish, with brownish cloudings and many bright red 
spots on head, body, and fins; black blotch on dorsal fin on eighth to tenth spines, fin clouded with 
dark bars; dermal flaps white. 
Another fresh example (field No. 206) golden brown on body and fins, with many very bright red 
spots; a black blotch on spinous dorsal on seventh and ninth spines longer than eve but not so deep. 
in alcohol the color varies considerably; in some, fins distinctly branded, in others, fins plain. Some 
lack the black blotch on posterior part of spinous dorsal, others have it present but small, others have it 
well developed and reaching from sixth to eleventh spine. A series of dermal flaps along lateral line, 
also a number of smaller ones on lower half of side; lateral line simple, slightly convex downward 
posteriorly. 
Color of type (field No. 236) in alcohol, head and body mottled with lighter and darker shades 
of brown, plain pale below; a wide, pale transverse band on napie (very indistinct); spinous dorsal 
with dusky blotch from seventh to tenth spines on distal half of fin; other fins mottled with brown in 
triangular transverse bands; a dusky rim above margin of eye on eye membrane; dermal flaps white. 
Resembles Scorpstma onaria Jordan & Snyder from Japan, but differing in absence of knob at 
Fig. lQQ.—Scbastapistes corafficola Jenkins; from the type.
