S. TANAKA : 



directed a little downward. Third spine directed downward, and fourth 

 spine downward and forward, both these two spines being entirely concealed 

 in the skin. Suborbital stay distinct, not projecting out in a spine. Post- 

 temporal spine and opercular spine end at almost the same vertical, not 

 reaching to the end of opercular flap. Humeral spine in a line with the 

 opercular one, projecting a little out of skin. Lower end of subopercle 

 and upper end of interopercle each with a sharp spine, their end converg- 

 ing and nearly touching ; the upper one pointed downward and back- 

 ward, the lower one upward and backward. 



Gill-membranes confluent, forming a rather broad fold across the 

 isthmus; gill-rakes on the first gill-arch 2 + 8, stumpy. No slit behind 

 last gill. 



Top of head covered with hard warts, becoming a little less warty on 

 the sides ; no plates on head. Skin of body with some scattered, rough 

 tubercles, arranged in some two or three longitudinal rows ; those 

 converge backward, and unite into a single row in the posterior part and 

 then this continues on to near caudal base. Lateral line complete, with 

 small concealed scales. Skin below the lateral line a little or not at all scaly. 



Dorsal spines rather low, the membrane between spines scalloped, but 

 its outer margin rounded in general contour ; tips of the spines scarcely 

 reaching origin of soft dorsal when depressed. Soft dorsal high, the 

 membrane between the rays scalloped, but its outer margin rounded in 

 general contour ; tips of rays extending a little beyond the origin of 

 uppermost ray of caudal. Anal originating below fourth dorsal ray, the 

 rays a little lower than dorsal rays ; the membrane between rays incised but 

 its outer margin rounded in general contour ; last ray originating a little 

 before last ray of dorsal ; tip of longest rays falling far before caudal base. 

 Membranes behind last rays of dorsal and anal adnate to body. Pectoral 

 nearly not reaching anal ; its posterior margin rounded ; the lower rays 

 procurrent. Ventral extending four-sevenths the distance between its 

 origin and anal. Posterior margin of caudal a little rounded when spread 

 out, nearly truncate when closed. 



Color in formalin brownish above and on the sides, whitish beneath.
