 latus, and Lampania multiformis. 



The shells bore the marks of age, having that peculiar yellowish nnd chalky 

 color and characteristic appearance of the nacreous portion, gem rally seen in 

 shells long buried in the ground. 



Not a single fragment of ancient pottery was found. On the contrary, frag- 

 ments of tiles and a lew pieces of glazed pottery and poicela'n of Owari and 

 Kioto, were met with. 



The two species of Ost.rea formed the bulk of the deposit. 



Specimens of Cyclina Chinensis were very large. A single small specimen 

 only of Turbo granulatus was met with. Special search, however, was made for 

 Purpura luteostomn and particularly for Area gränosa, but no trace of either 

 was found. Area inflata had the same narrow hinge area that the species presents 

 to-day. In fact no appreciable change has taken place between the species living 

 two hundred and thirty years ago, and their descendants which live at the pre- 

 sent time. 



Another deposit of shells, somewhat old, judging from the appearance of the 

 shells, was examined near Kameido, and no trace of Area granosa was found- 

 nor trace of pottery. 



The occurrence of Area granosa, in this region at least, may be looked upon 

 as an evidence of the presence of ancient cord marked pottery.
