ling distance from posterior edge of mouth to gill-opening; anal opposite and 

 similar to dorsal; pectoral broad, short, almost truncate; upper rays shghtly 

 longer, equal to snout in length. 



Color in spirits uniform dusky ashen above upper level of gill-opening, 

 darker on back; an ocellated spot considerably larger than eye near tip of 

 pectoral; area at base of dorsal dark, but without distinct spot; under parts 

 white. Dorsal, anal, and caudal tipped with blackish; pectorals dusky brown; 

 sides and back without any indication of stripes or spots, except the pectoral 

 spots. 



This species resembles Spheroides alboplumbeus of Japan and Southern 

 China, but differs in size of eye, interorbital width, etc., and also in color, S. 

 alboplumbeus being covered above with conspicuous white spots. 



Family TRICHODONTID^. 



170. Arctoscopus japonicus Steindachner. 



Chinnami^o (No. 4109a-c). Several fine specimens were obtained agreeing 

 perfectly with Steindachner's original description and figure. 



The figure published by Jordan and Evermann (Fishes of North and Middle 

 America) from deep water off Iturup Island represents a deeper fish, perhaps 

 specifically distinct.
