We may here record a new species of Hexagrammus 

 from Tokio, Japan, hitherto confounded with the Amer- 

 ican species Hexagranwiiis hexagrammus. 



Hexagrammus otakii Jordan & Starks, n sp. 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 13^ ; ventral i^ ; cau- 

 dal i>^. 



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,
