We may here record a new species of Hexagrammus 
from Tokio, Japan, hitherto confounded with the Amer- 
ican species Hexagrammus hexagrammus. 
Hexagrammus otakii Jordan & Starks,nsp. Plate Ixxvii. 
Head 4 in length to base of caudal; depth 4%; dorsal 
XIX-—23; anal 21; scales 21-106—-34; eye 4% in head; 
snout 3%; highest dorsal spine 2%; \highest dorsal ray 
2%; highest anal ray 3; pectoral 1% ; ventral 1%; cau- 
dal 1%. 
Body elongate, not greatly compressed, the head small 
and pointed. Mouth not large, the maxillary reaching | 
slightly past the vertical from anterior rim of orbit; jaws 
subequal; teeth conical and sharp, the outer row enlarged, 
smaller on vomer, none on palatines; interorbital space 
broadly convex; a wide, short, multifid dermal flap over 
posterior edge of each eye. 
Head scaled above to slightly in front of eyes, opercle 
and cheek entirely and densely covered with small scales; 
snout, preorbital, suborbital, lower jaw and interopercle 
naked. Scales everywhere, except on cheeks and oper- 
cles, strongly ctenoid. 
Lateral lines 5 on each side; the upper one from nape 
parallel with dorsal, stopping under the beginning of pos- 
terior fourth of soft dorsal, sometimes uniting with the 
second lateral line at this point, not joining its fellow of 
the opposite side in front of dorsal; the second running 
parallel with it, continued to base of caudal, situated be- 
low the first in distance equal to half eye; the third, par- 
allel with curve of back, running from the upper end of 
the gill-opening to the base of the caudal; the fourth 
short, beginning slightly in front of ventral, past the outer 
edge of its base, not reaching to its tips; the fifth parallel 
to anal, in distance above it equal to space between upper 
lateral lines, barely reaching base of caudal posteriorly,
