92 ME. A. ADAMS ON JAPANESE GASTEEOPODS. 



ploratiou of the coasts of Japan by H.M.S. ' Actaeon ' are all well- 

 knowu species; in the family TricJiotropidce I was fortunate in 

 finding a new Iphinoe and a beautifully-sculptured Tricliotropis, 

 besides nearly all the known species of that group. In the 

 Cowry tribe nearly all the species are old Linnean shells. They 

 are most numerous along the Pacific shores of the Japanese 

 Islands, and more especially along the southern and eastern parts 

 of Kiusu. The coral reefs of the Tropics are badly represented in 

 Japan, and it is among the recesses of these that the Cowries 

 delight to live. One new species only, belonging to the Amphipe- 

 rasidce, has occurred to me, most of the specimens found having 

 been previously described by Sowerby from examples brought 

 home by Sir E. Belcher and myself in H.M.S. ' Samarang.' The 

 present paper presents a striking contrast to the others I have 

 recently ofiered to the Society, which were principally composed 

 of new species.
