Tipper profile slightly convex to beginning of dorsal, sliglitly depressed beliind eye. 

 Eye and snout 4§, interorbital space 5^ in head. Maxillary reaching to posterior rim of 

 orbit, in older individuals somewhat farther. Inferior border of preorbital with 3 more or 

 less rounded lobes, the last -with a short blunt spine. Interorbital space between the ele- 

 vated supraocular ridges weakly convex. Head entirely scaled, except jaws, snout (in 

 front of nostrils), preorbital, and nearly the whole of iuteropercle ; scales of head small, 

 firm, rough, with accessory scales like those on body. Preopercular spines 5, short, broad, 

 blunt. Spinous dorsal uniformly rounded ; fifth and sixth spines longest, in young, 2, in 

 adults nearly, 2^ in head. Second anal spine much stronger, but little longer than third, 

 2i to 2s in head. Pectoral about § in head ; ventral more than Ig in head ; caudal equalling 

 ventral, slightly convex; 36 to 39 pores on body, 2 to 3 on base of tail. Blackish brown, 

 with innumerable small white dots on body and fins. In some individuals the uniform 

 dark brown of body is interrupted by lighter shades. (Steindachner & Doderlein.) 

 Length 10| inches. Not rare at Tokio; 1 specimen at Hakodate.

Head 2J to 2i; depth less than 3 (3i in total length). D. XIII, 12; A, III, 7 or 8; lat- 

 eral line about 66 to 70. Nasal, preocular, postocular, tympanic, and parietal spines 

 present; interorbital space probably concave, with interorbital ridges. Orbit 4A; snout 

 (to tip of slightly projecting chin) a little less than 4 ; interorbital space 4f to 5 in head. 

 Maxillary reaching posterior margin of orbit. Preorbital with 2 to 3 sharp spines directed 

 downward and backward. Preopercle with 5 flat spines, the second from above longest, 

 horizontal, the fifth (in adults) often blunt and broad. Iuteropercle with a weak, sharp 

 spine, beside it sometimes another on lower end of subopercle. Head scaled ; jaws, snout, 

 and anterior part of preorbital scaleless. Scales on iuteropercle extremely small. Several 

 large pores on uuder side of lower jaw. Sixth and seventh dorsal spines longest, a little 

 more than 2 in head. Second anal stronger, sometimes a little shorter, sometimes a little 

 longer than third, 23 to 3 in head. Pectoral a little longer than ventrals, about IJ in head. 

 Caudal nearly truncate. Tip of venti-als reaching, pectorals not quite reaching vent. 

 Brownish gray (in alcohol), with lighter and darker shades ; a dark stripe on maxillary, 

 and 2 or 3 on cheek ; opercle above and below with washed out spot. (Steindachner & 

 Doderlein. ) Length 12 to 15 inches. Quite common at Tokio; Gulf of Strietok, Sea of 

 Japan ; Yezo, Tedo, and Hakodate.

 line 36 (tubes). Cranial spines promiuent; nasal, preocular, postocular, tympanic, and 

 parietals present. Interorbital space 1 to IJ in vertical diameter of orbit, 4J to 5 in head, 

 concave, with a pair of interorbital ridges at the sides of a median groove. Preorbital
