Notes. 
Yezonia vulgaris , gen. et spec. nov. A Gymnosperm, of which stems, unthickened 
twigs, and leafy axes are all very plentiful. It is the commonest plant in the material, 
and at the same time the most unique. In the anatomy of both main axis and 
foliage it is not like any known type. 
Yezostrobus Oliveri, gen. et spec. nov. The fructification of a Gymnosperm, the 
cone bearing simple scales with seeds, one on each, which are like those of Cycads 
in some respects, but have a nucellus standing up entirely free from the integument 
with a well marked epidermis between. 
Though continuity is lacking between these two fossils, there seems considerable 
ground for suspecting them of belonging to the same plant from anatomical points 
of likeness. 
Araucarioxylon tankoense , spec. nov. Secondary wood, showing remarkably clear 
pittings in the transverse sections. 
Cedroxylon Matsumurae , spec. nov. Well preserved secondary wood. 
Cedroxylon Yendoi , spec. nov. Secondary wood, with traumatic resin canals. 
Cunninghamiostrobus yubariensis, gen. et spec. nov. A cone, as its name implies, 
belonging to the family of the Cunninghamias, with its external appearance partly 
preserved, and the cone scales and axis fairly well petrified. The seeds have 
apparently been scattered. 
Cryptomeriopsis antiqua, gen. et spec. nov. Stem with leaves attached, the foliage 
very like that of a Cryplomeria. 
Saururopsis niponensis , gen. et spec. nov. The stem and attached roots of an 
Angiosperm, probably to be included in the Saururaceae. 
Jugloxylon Hamaoanum, gen. et spec. nov. The secondary wood of an Angiosperm. 
Populocaulisyezoensis, gen. et spec. nov. The stems of an Angiosperm, with cortical 
tissue. 
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 Angio¬ 
sperm, with cortex, and well preserved and characteristic anatomy. 
Cretovarium 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 Royal 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.
