Fagoxylon hokkaidense, gen. et spec. nov. The secondary wood of an 

 Angiosperm. 



Sabiocaulis Sakurii, gen. et spec. nov. Minute stems, and older twigs of 

 an Angiosperm, with cortex, and well preserved and characteristic 

 anatomy. 



Cretovarmm japonicum, gen. et spec. nov. The flower of an Angiosperm, of 

 which there are several specimens. 



Of this list of plants, the commonest, i.e. those which have yielded the 

 greatest number of specimens in the course of the work, are Yezonia, 

 Sabiocaulis, and Cretovarium. It is noteworthy that these are among the 

 most unusual and the most interesting of the plants. 



The authors acknowledge much assistance in the work from the Eoyal 

 Society Government Grant Committee, which made it possible for one of 

 them (M. C. S.) to attempt the work ; and from the various departments of 

 the Imperial Government of Japan in the course of collecting and preparing 

 the material.
