306 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. xxvii. 



Anterior part of latoral line double curved and sparselj" fringed 

 with small tentacles; below it and above pectoral are 1 or 2 rows of 

 small rough plates which do not extend posterior to pectoral. 



Pectoral with 14 rays, the lower 8 swollen; its tip reaches to above 

 base of second or third anal ray. The anterior 3 dorsal spines shorter 

 than those just behind; the third spine shorter than the first, notching 

 the outline of the fin; first spine 3i in head, the third 3f ; the fourth 

 3. Behind the fifth the spines rapidly decrease in length; the dorsals 

 joined at the base, but not nearly so broadly as in 1\ J.shikawse. ■ Sec- 

 ond dorsal higher than first; the longest rays ^1\ in head; the last ray 

 is adnate to caudal peduncle; the tips of the last ra3's reach past those 

 of anal, usually scarcely reaching to above base of caudal. Anal 

 lower; the last ray free from caudal peduncle; the longest rays 3 in 

 head. Caudal more rounded than in F. ishiluwa^.; the middle rays of 

 the closed fin reaching beyond the outer rays, its length is If in 

 head. 



Color nuich as in F". Ish/l'awse; the cross markings the same, 

 though more broken u]), and the lower part of the sides more finely 

 mottled; pectoral similar; spinous dorsal uniforndy mottled, ci'oss 

 ))ands, soft dorsal, anal, and caudal wider and darker; the anal never 

 uniformly dusky toward tips of rays; the branchiostegal rays usually 

 strikingly marked with a streak of milk Afhito along each ra^", in strong 

 contrast with the unpigmented breast; a small area in front of them 

 white; the membrane ])etween each ray is often ))luck. 



This species may be at once known from F. i.s/t/'kd/rw ])y the fewer 

 fin rays. th(^ more widel}" forked preopercular spine, and by the 

 deeper notch in spinous dorsal. Of the 10 specimens of this species 

 and 30 or 40 of F. w/u'hMrx that were examined, no variation of fin 

 rays was found outside of the limits here given. 



This species is probabl}' less common than F. ishikawse-. Speci- 

 mens were taken at Hakodate and Misaki. The type is from the 

 former place; it is 77 nun. in length and is luunl^ered 771(), Ichthyo- 

 logical Collections, Leland Stanford Junior ITni versify Museum. A 

 cotype is No. 50925, U.S.N. M. 



(From O.shh/ta, great island, the province of Hokkaido, of which 

 Hakodate is the capital.) 



81. OCYNECTES Jordan and Starks. 



Ocyufdi'K Jo]UK\s and Stakks, new o;enu8 [innxchiilis). 



This genus is closely related to Jjero, but difl'ers particularly in the 

 character of the lateral line, which is not undulating anteriorly and is 

 not protected by concealed plates, but usualh" has a small tentacle at 

 each pore. The pectorals are very large, half the length of body with- 

 out head, or exceeding the length of head.
