 Corythroichthys quinquarius Snyder, Proc. U. S. Nat. Mua., vol. 40, 1912, p. 526. 

 Tanegashima, Japan. 



Thirteen specimens, one male and twelve females, were secured by 

 seining in shallow water. All are much alike in color. The dorsal 

 covers 6.5 to 7 rings. The dorsal rays number from 26 to 28. 



TRACHYRHAMPHUS SERRATUS (Temminck and Schlegel). 



Misaki; one specimen from a pool. 



UROCAMPUS RIKUZENIUS Jordan and Snyder. 



One specimen was taken in Matsushima Bay where the species was 

 first seen. In this example the dorsal fin is confined to 4 rings. 

 Otherwise it is like the type. 



MICROPmS OCELLATUS Snyder. 



Tanegashima pools, where the species appear to be rare. 



MICROPHIS BRACHYURUS (Bleeker). 



Three specimens taken with the seine near shore at Tanegashima 

 do not appear to differ from Samoan examples.

 interorbital area, the ridges of the snout more pronounced and the 

 serrations of the same better developed. The body is deeper, the 

 caudal peduncle broader, and the lateral line much more strongly 

 armed posteriorly. The snout is longer, deeper, and heavier.
