By Masamitsu Oshima^ Ph.D. 



(Pl. XIII, FIGS. 2-2,.) 



The present paper gives a review of the fishes of the family 

 Centriscid(B found in the waters of the Island of Formosa. It is 

 based on the material in the Institute of Science of the Government 

 of Formosa, collected by Mr. Muneshige Watanabe of the Marine 

 Experiment Station at Tainan, and Mr. Akitaro Kihara of the Toko 

 Fish Market. I express my hearty thanks for the courtesy shown by 

 those two gentlemen. • 



Family CENTRISCIDyE. 

 (The Shrimp Fishes.) 



Form of body elongate, much compressed. Anterior bones of skull 

 much produced and forming a long tube terminating in a small mouth. 

 B6dy covered with a bony dorsal cuirass, which is connate with the 

 internal skeleton, ending posteriorly in a long projection, which has 

 sometimes a movable spine at its end. Longitudinal axis of the tail 

 deflected from that of the trunk through the encroachment of the 

 dorsal cuirass. Dorsal fins two, crowded together under the terminal 

 spine of dorsal cuirass. Ventrals abdominal. Teeth none. Parietals 

 absent. Post-temporal suturally connected to cranium; supraclavicle 

 present. Ribs developed. Postclavicles present. 



Habitat: Indian Ocean to Western Pacific. 



Species few and small, fantastically formed, the translucent cara- 

 pace suggesting that of a shrimp (Jordan & Starks).
