Family OSTRACIIDtE. 



222. Ostracion diaphanum Bloch & Schneider. 

 Misaki, No. 6151a-c. 



223. Ostracion stellifer Bloch & Schneider. 

 {Ladophys tritropis Snyder). 



One specimen, No. 6447a, 8 cm. long, from Misaki. This is identical with the 

 cotypes of Lactophrys tritropis Snyder,^ No. 21424 Stanford University Collection, 

 with which it was compared. It was also compared with a specimen of L. stellifer 

 (Bloch) from Sydney and found identical in all respects, save the slightly smoother 

 appearance of the scales; counts, measurements, color, spines, and shape were the 

 same. The cotypes of L. tritropis Snyder, and the specimen at hand, are probably 

 the young of the species erroneously termed Lactophrys concatenatus (Bloch). 

 The original of the latter was a West Indian species, identical with Ostracion 

 triqueter Linnaeus, Bloch having described it and copied his plate from a drawing 

 by Pliimer of a specimen from Martinique.* 



The name Ostracion stellifer Bloch & Schneider is then the oldest name of the 

 species, and must be used instead of concatenatum (Bloch) . The species is recorded 

 as stellifer by Bleeker from Japan, but the earliest reference we have found is in his 

 " Nieuwe Nalezingen "* without locality other than Japan. In later lists it was 

 evidently termed Ostracion concatenatum. 



224. Ostracion immaculatum Temminck & Schlegel. 

 Misaki, No. 6260a-f. 



A small specimen has black spots on dorsal and lateral surfaces; the others are 

 normally colored. 



225. Ostracion fornasini Bianconi. 

 Misaki (Coll. Aoki). 



One young example identical with one from Lord Howe Island. Irregular 

 spots and lines of pigment over head and upper half of body. This species has not 

 before been noticed in Japan. 



226. Aracana aculeata (Houttuyn). 

 Misaki. 



Lateral ridges in young with five small spines, ventral with six.
