66. PARAPERCIS PULCHELLA (Schlegel). 



612. Yokohama. 



The generic name Farapercis Bleeker 1872 {oylhulrlca) must replace 

 Percls, which was first o-ivon hy Scopoli to a u-emis of Agonidw. Para- 

 ;?,>/'c/./steindachner is a ditlerent genus, sul)sequently called Neopefrch 

 by the same author. 



Family ECHENEID^. 



67. REMORA SEXDECIMLAMEI.LATA ( Eydoux and Gervais ). 



Yokohama. 



Plates 17. Perhaps identical with Ri'iuont l>r(ic/ii/j>i<i'<i of the Atlan- 

 tic. Comparison of specimens is needed. 



Family GOBUD.F:. 



68. CTENOGOBIUS SIMILIS (Gill). 



(Plate XXXV.) 



{Rhinogobius similis Gill, young.) 

 {Gobius yokohamx Giinther, female.) 



Tsushima. 



Specimens very large and dark, much larger than those from Tokyo, 

 Nagasaki, or Lake Biwa. The male with the dorsal edged with white, 

 the" first spine produced in a long filament. Mouth larger and lips 

 thicker in the male than in the female. This is the commonest species 

 of goby in the streams and lakes of Japan, abundant everywhere 

 southward in sluggish water among weeds. We have specimens from 

 Tokyo, Lake Biwa, Tsushima, Aomori, lyo in Shikoku, Kurume, 

 Kawatana, and Nagasaki. We may perhaps recognize Ctenogobim 

 {^Rkmogohius, AcentrogoMus, etc.) as distinct from Gohius^ wanting 

 the free or silky rays of the upper side of the pectoral, which are 

 characteristic of the typical species of GoUu^s, none of which are 

 found in Japan. In CtenogoUus, as in Ahoma, the isthmus is very 

 broad, the mouth moderate, the tongue not notched, the head rounded 

 above, and the scales rather large and ctenoid. Ahoma apparently 

 differs from Ctenogdnm in having seven or eight anal spines instead 

 of six.
