JORDAN AND RICHARDSON : KISIIES OF TDK ISLAND OK FORMOSA 



177 



91. Polydactylus zophomus Jordan & McGregor. 



Kotosho (Jordan & Evermann) (as P. plebeius). 



92. Eleutheronema tetradactylum (Shaw). (Polydactylus rhadinus Jordan & 



Evermann.) 



Fig. 10. Eleutheronema tetradactylum (Shaw). (After Jordan & Evermann, Proe. U. S. N. M., Vol. 25. p.351.) 



Two specimens, respectively ten and twelve inches long, from Takao. De- 

 scribed from Formosa by Jordan & Evermann as Polydactylus rhadinus. Our speci- 

 mens agree fairly well with the published figure of Jordan & Evermann. 



The genus Eleutheronema Bleeker may perhaps be retained as defined by the 

 absence of the air-bladder. This is present in Polydactylus. 



Family HOLOCENTRID.E. 



93. Ostichthys japonicus (Cuvier & Valenciennes). 



Formosa (Jordan & Evermann). 



Family SCOMBRID/E. 



94. Scomber japonicus Houttuyn. 

 Formosa (Jordan & Evermann). 



95. Rastrelliger kanagurta (Russell). 



Formosa (Jordan & Evermann). 



96. Euthynnus alleteratus (Rafinesque). 



Three specimens ten inches long from Takao. Formosa (Jordan & Evermann). 

 The genus Euthynnus Liitken should apparently be separated from Gymnosarda 

 (nuda). The latter has the corselet scaleless, covered by wrinkled skin (Riippell). 



97. Scomberomorus commersoni (Lacepede). 



(Native name To to.) 



One specimen twenty-one inches long from Takao. 



98. Scomberomorus guttatus (Bloch & Schneider).
