JORDAN AND THOMPSON: FISHES OBTAINED IN JAPAN IN 1911. 273 



channel, and ending occasionally in a spine. Maxillary ending below posterior 

 margin of orbit (not below middle, as in Thysanichthys crossotus Jordan & Starks). 

 Lower jaw not projecting. Gill-rakers short, 10 on anterior limb of arch. 



Scales ctenoid, not present on snout and maxillary, between interorbital 

 regions, present on cheeks and opercles; fins naked, save base of pectoral and soft 

 fins; lateral line without series of filaments; which are present on spines of head in 

 part, none as long as in Thysanichthys crossotus. 



Pectoral reaching to first anal spine; ventrals nearly to anus; dorsal and anal 

 spines with channels. Fifth dorsal spine highest, 2.6 in head, thirteenth 3.166 in 

 head, twelfth slightly more than half of thirteenth; second anal spine longest and 

 strongest, 2 in head. Peritoneum white. 



Color in spirits dark olivaceous, vaguely mottled. 



240. Sebastichthys pachycephalus (Temminck & Schlegel). 

 Misaki, No. 6224a-b. 



Color very dark. D. XIII., 12; A. III., 7; pores 27. 



241. Sebastichthys elegans (Steindachner & Doderlein). 

 (Mem. Carn. Mus., Vol. VI, fig. 45, p. 51). 



Idzu Sea, No. 4325a-b; from Owston Collection, Yokohama; Shimonoseki. 



242. Sebastichthys mitsukurii (Cramer). 

 Shimonoseki, No. 6213a-c. 



243. Sebastiscus albofasciatus (Lacepede). 

 {Sebastes marmoratus Cuvier & Valenciennes). 



A. Osaka, No. 6343a, 6346a-l. Comparison of numerous specimens fails 

 to show any distinction, except in color, between the common shore-form of Se- 

 bastiscus, called marmoratus, and the form albofasciatus, taken in deeper water. 

 The former is dull olive and brownish in color, the latter of vivid shades of red and 

 pink. Both forms are very common and some specimens seem to intergrade. 



B. Tsushima Straits: the bright red form called albofasciatus common in the 

 trawlers' catches. None of these has the spine below the eye, supposed to dis- 

 tinguish the red form from marmoratus of the shore. The eye varies greatly in size. 



C. Shimonoseki, Nos. 6204, 6345a-e. Both the orange deep sea form {albo- 

 fasciatus) and the brown shore form (marmoratus). 



D. Misaki, No. 6148a. 



244. Helicolenus emblemarius Jordan & Starks. (See Fig. 41, p. 274). 

 Misaki, No. 6236a, young (Coll. Aoki).
