FamUy OSTRACIID/E. 



OSTRACION IMMACULATUM Temminck and Schlegel. 



Misaki. 



OSTRACION DIAPHANUM Bloch and Schneider. 



^Misaki. 



One example has the sides of carapace parallel to about the base 

 of pectoral, where they rather abruptly flare outward.

 Lactophrys tritropis Snyder, Proc. U. S. Nat. Mus., vol. 40, 1912, p. 535. 



Misaki pools. 



Family TETRAODONTID.^. 



SPHEROroES SPADICEUS (Richardson). 



I^Iisaki; Shimizu; Kagoshima. 



In life the specimen from Shimizu was light brown above with a 

 golden tinge, the lower parts suffused with golden yellow; spots 

 dark brown; iris orange red. 



SPHEROroES ALBOPLUMBEUS (Richardson). 



Mororan, Hakodate, and Tokyo markets; Mori, with the seine; 

 Otaru, Mororan; Aikawa, and Alisaki pools. 



This species, very like the above, may be distinguished by its gen- 

 erally larger and fewer spots, by the absence of minute wliite tubes 

 above and below the lateral line, and by the large, dusky blotch 

 on the caudal. 



In some specimens of S. alhoplumheus the white spots are numer- 

 ous enough and sufficiently close together to appear like ocelli; in 

 some specimens the spots have a narrow dark border; while in other 

 examples the spots join, forming light reticulations. Sometimes the 

 latter tend to meet, thus inclosing round, dark spots, and causing the 

 individual to resemble one of S. pardalis. Specimens of S. pardalis 

 are easily distinguished by the presence of numerous small thickenings 

 of the surface of the skin which look much like embedded scales. 

 There appears to be some doubt concerning the validity of S. horealis 

 Jordan and Snyder, it being possible that the species is foimded on an 

 extreme variation of S. alhopluinbeus. 



SPHEROIDES STICTONOTUS (Temminck and Schlegel). 



Aikawa; Tokyo market. 



Three specimens are closely spotted and finely reticulated above. 



SPHEROIDES PARDALIS (Temminck and Schlegel). 



Mororan and Tokyo markets; Aikawa, Misaki, and Shiogama 

 pools. 



SPHEROIDES EXASCURUS Jordan and Snyder. 



One specimen from !Misaki is in all particulars like the type of 

 the species.
