NO. 1263. JA PANESE TRA CHINOID FISHES— JORDAN AND SNYDER. 487 
Dorsals separate, the spinous dorsal inserted on a line passing a little 
behind base of ventrals, the soft dorsal inserted immediately above 
anal, both fins extending an equal distance posteriorly; caudal notched, 
pectorals and ventrals pointed. 
Color in spirits, plain brownish yellow, a faint trace of dusky on the 
distal parts of the fins. 
Coast of India, from the Red Sea to Japan, generally common; our 
specimens from Tokyo, Tsuruga, Onomichi, and Formosa. It is appa- 
rently much less common than S. japonica^ on the coasts of Japan. 
Dr. Gill separates S. malaharica as a distinct species having the soft 
dorsal spotted. Our specimens agree with S. sihcmia in this regard.

Head 3f in length; depth 5|; depth of caudal peduncle 3i in head; 
eye 4i; snout 2i; interorbital space -li; pectoral 6f in length; ventral 
7|; caudal 6i; D. XI — I, 22; A. II, 23; scales in lateral line 70; in 
transverse series 16; between lateral line and insertion of dorsal 3. 
This species closely resembles S. sihama, diflering from it mainly 
in having the scales of the head ctenoid, and in having larger scales 
above the lateral line, there being but three series between lateral 
line and insertion of dorsal. 
Coasts of Japan and southward to Molucca; everywhere common, 
especially southward from Matsushima; an important food-fish. Our 
specimens are from Hakodate, Matsushima, Tokyo, Misaki, Niigata, 
Tsuruga, Wakanoura, Hiroshima, Onomichi, Kawatana, Hakata, and 
Nagasaki. 
21. SILLAGO PARVISQUAMIS Gill. 
Sillago parvisquamis Gill, Proc. Ac. Nat. Sci. Phila., 1861, p. 505; Kanagawa, near 
Yokohama. 
Head 3f in length: depth 6i; depth of caudal peduncle 4 in head; 
eye 5^; snout 2^; interorbital space 4^; pectoral 7 in length; ventral 
7f : caudal 7; D. XI-I — I, 22; A. II, 23; scales in lateral line 82; in 
transverse series 17; between lateral line and insertion of dorsal 6. 
Sillago jxirvisquam is is easily distinguished from S. sihwna by the 
smaller scales on body, there being a larger number in the lateral line 
and between the insertion of dorsal and lateral line. The scales of the
