but with the light streaks wider; sides of body with few filaments and 
no well-defined round white spots. 
The cliief points of difference between this species and the next are 
the following: I^o'ojjhryne histrlo has \e.Y\ few pale spots or dots on 
bod}'; the filaments are more numerous and stouter, the four dark 
bands on the caudal more sharply defined, the belly with a few dark 
spots. 
Coasts of Japan, in the open sea or current of the Kuro Shiwo, not 
rare. Our two specimens are from Kisaki and Enoshiiiia. 
The s3'nonjmy of this species is extremely dou])tful. Probably 
most of the descriptions published under the names of marmoratns and 
Jiixtrh) belong to it. The American species, called Pteropltrune histrlo 
l)y Jordan and Evermann, if distinct, should probabh' stand as Ptero- 
jjhryne tumida (Osbeck). This species was based on specimens from the 
Sargasso Sea, while the original type of Loj)hius Idstrio was Chinese.
