552 PROCEEDINGS OF THE NATIONAL BIVSEVM, vol. 41. 



Preopercular angle produced backward somewhat, its margins finely 

 serrated. Opercle with two small inconspicuous flat spines. Teeth 

 in jaws only, bluntly conical, minute, largest in external rows. 



Dorsal deeply divided; last dorsal spine one-fifth of fourth, which 

 is longest and 2 in head; spines strong, a stout procumbent one present 

 anteriorly. Spinous dorsal outline rounded, not concave. Rays 

 slightly longer anteriorly, 2^ in head. Anal spines stout, second 

 longest and strongest, 4 in head, third 6; third ray longest, 2 J in 

 head. Pectorals short, broad, their length contained If in head. 

 Ventrals about equal to pectorals. Caudal 1§ in head, its margin 

 rounded. 



Scales roughly ctenoid, lacking before nostrils on snout and jaws, 

 replaced by papillate skin; present on exposed portion of maxillary, 

 at bases of soft anal and caudal, and in low sheath at base of spinous 

 dorsal, not extending on soft dorsal or anal, save as a minute row on 

 each side of rays and of dorsal spines. 



Color of alcohoUc specimens nearly uniform, but showing traces of 

 dark bands much as in Plectorhynchus cinctus, that is, a rather narrow 

 one from the nuchal region, down through the area behind the pec- 

 toral and back in a long arch to the lower part of the caudal peduncle; 

 another parallel to the first from the first dorcsal spines to the upper 

 part of the caudal peduncle; and a third below the soft dorsal. Fins 

 all dark, without pattern. A young specimen shows a clear caudal; 

 first dorsal margined with black, and second dorsal and anal with 

 colorless edge. Peritoneum, gill and mouth cavities clear. The young 

 specimens have a very much flatter interorbital, eye 4 in head. 



Gtinther regards Hapalogenys maculatus as a doubtful synonym of 

 H. nigripinnis,^ and we see no reason to question this, especially as 

 our alcoholic specimens have nearly lost the bands which Richardson 

 regarded as characteristic of H. maculatus. Steindachner found no 

 procumbent spine in his example, but in our largest specimen this 

 was more deeply buried in the flesh than in the others, and his speci- 

 men was twice as large (41 cm.). 



This species is rather common in southern Japan. We have 

 examples from Wakanoura and Tsuruga.
