SOME TERTIARY FOSSILS FROM THE MIIKE COAL-FIELD. 15 



cuspidata of Agassiz (Recherches sur les Poissons Fossiles, III, p. 

 290, pi. 37a, figs. 45-50) so widely distributed in the Oligocène 

 of Central Europe. 



Our specimen is somewhat more subulate than most of the 

 forms figured by Agassiz, resembling in this respect L. elegans 

 of the same author, which however seems to be a little smaller 

 in size. 



Found at a depth of 393 feet (?). 



APPENDIX. 

 FOSSILS FROM HANGÖCHI, AMAKUSA. 



1. Crassatella fusca Yok. 



PL II. Fig, 4. 



There are several casts of a bivalve which on a closer 

 examination proved to be those of Crassatella fusca described 

 from Miike in the preceding pages. 



It seems to be very frequent at Hangöchi. 



2. Lima amaxensis n. sp. 



PL III. Fig. 2. 



There is a single specimen of the right valve firmly at- 

 tached to the stone. It is ovately oblong, somewhat inequi- 

 lateral, oblique, compressed and thin. The surface is ornamented 

 with about fifty simple, straight, narrow, equal, radiating ribs 

 separated by intervals nearly as wide as the ribs themselves. 

 The ears are broken.
