LEPTOCEPHALUS NYSTROMI Jordan and Snyder. 



Tokyo and Kagoshima markets. 



It is scarcely probable that this species and L. heterognathus ^ are 

 synonymous, as suggested by Jordan and Kichardson.^ L. nystromi 

 has long, pointed pectorals, and the dorsal and anal have black 

 borders in the region of the tail. In L. heterognatlius the pectorals 

 are broadly rounded and the vertical fins are immaculate. 



LEPTOCEPHALUS MYRIASTER (Brevoort). 



Hakodate and Tokyo markets; seined in shallow water at Shiogama. 



LEPTOCEPHALUS KIUSIUANUS Jordan and Snyder. 



Misaki market. 



LEPTOCEPHALUS EREBENNUS Jordan and Snyder. 



Many specimens procured in the pools at Misaki. 



Head, 1.6 in the trunk; head and trunk, 1.6 in tail; lower jaw 

 usually equal to the upper in length, sometimes slightly included; 

 maxillary, 2.5 in head; distance from gill opening to origin of dorsal, 

 2.3 in head; height of dorsal, 6 in head. Pectorals very broad; 

 rounded in outline. Dorsal inserted near a point above tip of pec- 

 toral; sometimes an eye's diameter before or behind it. 



Family ^lURiENESOCID^E. 



MURSNESOX CINERSUS (Forskal). 



Kagoshima. 



Family OPHICHTHYID.^. 



OPmCHTHUS ASAKUS.S; Jordan and Snyder. 



A specimen examined in Yokahama had the origin of the dorsal 

 above the anterior third of the pectoral. 



PISOODONOPHIS ZOPHISTIUS Jordan and Snyder. 



JMisaki pools; Kagoshima market. 



The dorsal and anal increase in height just before reaching tip of 

 tail. 



MICRODONOPHIS ERABO Jordan and Snyder. 



One specimen obtained in a pool near Misaki. The original descrip- 

 tion of this species errs in stating that the head and trunk are a little 

 shorter than the tail, the opposite being true. A young specimen from 

 a pool at Misaki, apparently belonging to this species, was bright 

 grayish olive in life, the dorsal bordered by pearly blue. 



Family ANGUILLID.E. 



ANGUn-LA JAPONICA Temminck and Schlegel. 



Mororan, Shiogama, Tokyo, JMisaki, and Kagoshima markets; 

 seined near mouth of river at Akune.
