NO. 1263. / IPANESE TRA CHINOID FISHES— JORDAN AND SNYDER. 485 
.small patch on each side of vomer; pharvno-eals smooth. Pseiiclo- 
branchia? large; gill rakers on first arch 5 + IJr, long and slender. 
Preopercle with 5 large, slender spines, the central and largest one 
being on the angle; preorbital with a small spine which projects down- 
ward; opercle without armature. In our specimens, which are not 
well preserved, no scales can be detected on the head or body. Lat- 
eral lines single, without branches, passing along upper side of body; 
no trace of a second lateral line can be detected. 
Dorsals widely separated; the first spines highest, about If in head; 
base of second dorsal but little longer than that of the first, the rays 
somewhat shorter than the spines, when depressed falling far short of 
base of caudal. Anal fin very long, inserted below eighth dorsal spine, 
extending to base of caudal, the highest rays contained about 3^ times 
in head; caudal concave posteriorly; the basal rays extending far for- 
ward on caudal peduncle. Pectorals very large, the length contained 
about 3^ times in length of head and body, the posterior edge truncate. 
Color in spirits silv^ery, with small brownish spots on upper parts; 
a row of elongate, paired spots along the lateral line. Dorsals, caudal, 
and pectorals dusky. 
Described from a specimen from Kushiro about 120 millimeters 
long. 
North Pacific, rare; recorded from Strielok, Sitka, and Iturup Island. 
We have in addition 3 specimens from Kushiro, Hokkaido, and one 
from Tsugaru, near Aomori. The latter is No. 791, Trichodon sp. , of 
Ishikawa's list, the specimen being presented by the Imperial Museum. 
{Jajymiicus, from Japan.) 
Family VI. SILLAGINID^. 
Body elongate, little compressed, tapering both ways from the spinous 
dorsal; head rather elongate, conical in profile, the forehead flattened. 
Eyes lateral, submedian, the preorbital very large, concealing ends of 
maxillaries. Mouth small, terminal, the premaxillary little protractile. 
Teeth small, on jaws and front of vomer. Branchiostegals 6; pseudo- 
branchise present. Preopercle entire, bent inward below, covering 
lower surface of head; opercle small, with a short spine. Skull with 
muciferous cavities as in Scicenidce. Scales small, ctenoid. Lateral 
line simple, slightly curved, continued to base of caudal or slightly 
beyond. Dorsal fins 2, the first short, the second very long, similar 
to anal which has two small spines; caudal emarginate, with rounded 
lobes; pectorals normal; ventrals 1, 5; thoracic fins almost scaleless. 
Vertebrpe 12 to 16 + 22 to 27. Stomach csecal, pyloric cseca few. 
Air bladder simple. Fishes of the East Indian seas, distantly resem- 
bling the Sciaenidw, which are certainly their nearest allies, 
«. Teeth uniform; dorsal spines 11 or 12; soft dorsal similar to anal; scales rather 
small (50 to 90) ; ventral spine slender Sillago, 12.
