GENUS AND TEN NEW SPECIES OF JAPANESE FISHES. Ö 



separatcd from each other and from mouth, with a cirrus ante- 

 riorly. Gill-openings small, subequal, equidistant ; last one above 

 base of pectoral. First dorsal small, inserted slightly in advance 

 of origin of anal ; second dorsal inserted above end of anterior 

 three-fifths of base of anal, its base about | as long as that of 

 first dorsal. Anal long, but not high, highest in anterior parts, 

 continuous with lower lobe of caudal but with a deep notch ex- 

 tending to fin base. Pectoral rather large, but not extending to 

 ventral, posterior margin nearly straight. Ventrals separate from 

 each other, extending a little beyond halfway between their 

 origin and that of anal. Caudal not turned upward, its lower 

 lobe continuous with lower part of upper lobe with a slight notch, 

 the length of base of the former 4 times as long as that of the 

 latter. 



Scales very small, much smaller than in Scyliorhinus mac' 

 rorhynchus, giving much more finely velvety feeling to the touch. 

 Scales on head slightly less rough ; those on caudal peduncle 

 scarcely enlarged, not forming a distinct ridge ; without pit or 

 lateral keel. Lateral line evident, runs high, concurrent with 

 back, with a downward curve above end of the anterior fourth 

 of base of lower caudal lobe, whence backward it takes a course 

 near base of that lobe to tip of tail. Mucous pores well devel- 

 oped on head, much more so on under-surface of snout. 



Colour in formalin blackish brown, paler beneath ; posterior 

 edge of all the fins, edges of gill-openings and inside of mouth 

 black. 



The species is closely allied to Scyliorhinus viacrorhynchus, 

 but differs from this in having stouter body, unequal dorsals, 

 shorter snout, and finer scales. The species is not very rare in 

 the Japanese waters. The type, a male, captured by Mr. Aoki
