On the Japanese Species of Leiostraca. By Abthue Abams, F.L.S. 



[Bead Jan. 15, 1863.] 



In the " Annals " for 1861 I described twelve new species of Lei- 

 ostraca from Japan. To these I am now enabled to add many- 

 more from the same seas. The Inland Sea, or Seto-Uchi, I found 

 very prolific in species of this genus, as I did also Tobuko and 

 Uraga, at both of which places I obtained a portion of the bottom. 

 From the circumstance of their living in deep water, they are sel- 

 dom to be observed alive ; and, indeed, nearly all the species men- 

 tioned in this communication were obtained (with considerable 

 labour), from mud-washings and the sifted produce of the dredge, 

 in a dead state, and often with the markings obscure.
