On the Species of 2lllitr&z found in the Seas of Japan. By ARTHUR ADAMS, F.L.S., &c.

(Read Dec. 34 1863.j

T ~ E shores of the Japanese Islands which tW a s h e d by the Pacific are most prolific in species of Mit~idcz. Towaids the nbrth, 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.

Hab. Kino-0-Sima. The decussation of the small longitudinal plicse and transverse lire give

this species a granular surface. The colour is dingy white, stained and mottled with rufous.
