The following" color note was taken from a specinuMi in a fresh state: 

 Head and bod}* ahove brassy-, changing to light carmine l)elow; spots 

 on l)ody light olive green {bluish in life); spots at base of dorsal red- 

 dish yellow; tins all suffused with carmine; spots on dorsal and anal 

 same as on body; caudal spots whitish. 



This species is one of the most abundant of the shore tishes of Japan, 

 and varies widely in color, according to depth and condition. The 

 whitish spots along the ]>ase of the dorsal and the dark dots or bars 

 on the pectoral are very constant. 



SeJmstlcus alhofasciatus.. closely resem})les it, but may be known 

 by the bright red coloration and the presence of the small spine below 

 the ej^e, which is wanting in SSaHtlois maniiorafux. 



This species is known everywhere as Kasago. Our specimens are 

 from Hakodate, Same, Tokyo, Misaki, Sagami Bay, Enoshima, Suruga 

 Bav, Kobe, Hiroshima, Wakanoura, and Nagasaki It was dredged 

 by the U. S. Fish Commission steamer AlJ>atr<»<x in Suruga Bay, at 

 station 8718, off Ose Point, in 65 fathoms.

 AKAKASAGO (RED ROCK-FISH). 



Holocentrus albofasciatus Lacepede, Hist. Nat. Poiss., IX, 1802, p. 872; Japan; 



from a specimen in Mus. Berlin; coll. Langdorf. 

 Sebaiites albofasciatus Ccvier and Valenciennes, Hist. Nat. Poiss., I\', 1829, 



p. 344; after same specimen. 



Head '2h: in length without caudal; depth 3. Dorsal XH, 12; anal 

 in, 5. Pores in lateral line, 48. Eye 3| in head; interorbital width 

 7; maxillary 2\. 



This species differs but little from Sebastiscus marmorat'iis. I'he 

 cranial spines are usuall}^ sharper, and the ridges a little more acute; 

 at the lower run of the orbit on the upper edge of the suborbital stay, 

 is a sharp spine, directed backward and slightly upward, which is 

 entirely absent in S. marnwratus ; the eye is larger and the upper 

 simple rays of the pectoral slightly more produced, their tips alwa3's 

 extending well past tips of ventrals. 



The alcoholic specimens are more nearly colorless; they have a few 

 dusky spots on upper pectoral ra3^s, and the brown color on back 

 between light spots, extends slightly on dorsals; tins otherwise color- 

 less; the slight spots on back instead of being ^^ellowish, like an 

 alcoholic tish without pigment, as in S. marinoratus^ are with dead 

 white pigment. 



The following colors are shown hj fresh specimens: 



Bright scarlet with dark olive shades on back; the pale blotches on 

 sides of back violet or lilac; membrane of ventrals, anal and caudal 

 lobes above and below bright lilac violet; tins otherwise orange; the 

 membrane of the dorsal tipped with violet; pectorals pale, with dark 

 olive dots, toward the tip.
