dark spots, these forming transverse oblique rows directed 

 downward and backward on the side of body. 



The species is very closely allied to Astronesthes luclfer 

 Gilbert from the Hawaiian waters, but differs in the slenderer 

 body and in the longer ventrals and barbels. 



Five specimens of the species were taken in the Sagami Sea, 

 May 1907, and are contained in Mr. Alan Owston's collection. 



The species is named for Prof. Ijima of the Imperial Univer- 

 sity of Tokyo.
