On the Species of Mitridce found in the Seas of Japan. 

 By Aethue Adams, E.L.S., &c. 



[Kead Dec. 3, 1863.] 



The shores of the Japanese Islands which are washed by the 

 Pacific are most prolific in species of Mitridcs. Towards the north, 

 in the Sea of Japan, I met with no member of the family. A few 

 new species are here described, and a systematic list of all the 

 species which were actually obtained by me in those seas is given.
