The fossils which form the subject of the present paper 

 are those obtained between 1897 and 1904, during the sinking 

 of a shaft at a place called Manda in the Miike Coal-field. 

 The shaft was sunk to the depth of 884 feet below^ the surface 

 of the ground where there is a coal-seam about eight feet thick 

 which is now being extensively worked. The fossils are con- 

 tained in a dark greyish green sandstone which is fine to 

 medium-grained and quite hard. They belong mostly to dif- 

 ferent horizons ranging from 240 to 842 feet in depth, only a 

 few having been found in the same piece of stone. They are 

 tolerably numerous ; but owing to their bad state of preservation, 

 those which I was able to determine with any degree of ac- 

 curacy consist of two species of plants, a Crinoid, a Brachiopod, 

 eight species of Molhisca, two crabs and a tooth of a shark. 

 They are the following : — 



1. Cycas Fujiiana n. sp. 



2. Cedroxylon sp.
