 FISHES FROM JAPAN. 



BY DAVID STARR JORDAN AND EDWIN CHAPIN STARKS, 



Plates XX and XXI. 



Snyderina (scorp^nid^), gen. nov. 



Body I'obust, compressed, sparsely covered with non-imbricate, thickened 

 or granular scales. Head naked, ridged, without cranial spines. Profile 

 angulated in front of eye; preorbital with a long sharp spine. Preopercle 

 with a long sharp spine above and four smaller ones. Teeth villiform, in 

 bands on jaws and vomer; palatines toothless. Gill-membranes narrowly 

 united and narrowly connected with the isthmus. No slit behind fourth gill. 

 Branchiostegals seven. Lateral line present. Dorsal continuous, with about 

 thirteen spines and ten rays. Anal with three spines. First dorsal spine 

 short, inserted above middle of eye; last dorsal ray adnate to caudal 

 peduncle. Ventral rays i, 5. Pectoral without free ray. Caudal rounded. 

 Fins all scaleless. 



This genus is named for Mr. John Otterbein Snyder, in 

 recognition of his studies of Japanese fishes. It is allied 

 to Cocotro^us Kaup. 



The single known species is Snyderina yamanokami. 



Snyderina yamanokami, sp. nov. 



Plate XX. 



Head 2.6 in body; depth 2.7; eye 4 in head; maxillary 2.5. Dorsal xiii, 

 10; anal iii, 5. Pores of lateral line 21. 



Body compressed, the back elevated anteriorly, deepest over posterior 

 part of head, tapering to a rather small caudal peduncle. 



Head with many spines and ridges, the ridges smooth and covered with 

 thin skin. Profile very steep from first dorsal spine to snout, which latter 

 projects at a sharp angle and is less nearly vertical. Mouth very oblique, 

 the lower jaw slightly projecting. Maxillary broad at the posterior end, 

 transversely concave. Teeth finely viUiform, in bands on jaws and vomer; 

 palatines toothless. Width of interorbital space about two-thirds diameter 

 of eye. Two nearly parallel high sharp ridges run from first dorsal spine to
