of maiulihle somewhat raised and fitting' in a notch in niaxillarios, not, 

 liowt'Ncr. develoix'd in a knob. p]ye small, a little shoilcr tlian snout. 

 ]ntert)rhital Hat sometimes sliohtly concaved usual!}' unlu'oken by 

 ridges, sometimes with slight nearly parallel ridges running- backward 

 from nasal spines. Cranial ridges all low, the occipital ridges best 

 developed. 8pin(>s sharp but lying close to the skin and not })romi- 

 nent. Nasal, postocular, tympanic, and parietal spines present. Pre- 

 orbital with slight rounded lobes, no spines present. Preopercle 

 spines subeciually spaced or the two upper sometimes closer together 

 than others. Gill-rakers \QYy short and blunt, one-fourth or one-fifth 

 diameter of eye, 12 or 13 developed on anterior limb of arch. 



Dorsal spines longer than soft ra3's, the fifth '2\ in head; next to last 

 equals snout; last 1 in head. Notch between dorsals rather deep. 

 Pectoral rounded the lower 10 rays unbranched, its tip reaching 

 slighth' past ventrals to above vent. The second anal spine stronger 

 and as long as third 3 in head; first spine half as long. Tips of last 

 dorsal ra^'s reach to base of auxiliary caudal rays, and slightl}' farther 

 ])ack than those of anal. Caudal rounded. Peritoneum Avhite. 



Scales ctenoid. Soft fins except ventrals with a few small scales at 

 base. Preorbital scaled. Mandible and maxillar}- naked. Body 

 clouded and spotted with dark brown, these spots forming 1 or 5 more 

 or less conspicuous broken crossbars. Dark bars radiating from eve, 

 especially conspicuous in small specimens. Rays of soft fins with dark 

 spots which do not involve the membrane. All fins rather dark. 



This species, which must be extremel}' close to Sebastichthys ohlon- 

 (jus, we found abundant about the Inland Sea of Japan, and northward 

 even to Hakodate. Our specimens are from Hakodate, Aomori, ^Nlat- 

 sushima. Tokyo, Yokohama, Onomichi, Kobe, and Nagasaki. It may 

 be known from Seh<(stiehthys (MonguH by the presence of but 15 cross 

 rows of scales instead of 55 to 65. It is perhaps not really a distinct 

 species.
