 This volume is a continuation, under the same title, of the 

 "book which appeared more than ten years ago. The plan of arran- 

 gement, and scope of the volume are similar to those of the first 

 part, and it is similarly illustrated with numerous text figures. The 

 present volume deals with the foUowing groups of plants: the 

 Sphenophyllales are continued from the last volume, and their 

 treatment is concluded, the living Psilotaceae, and the fossils consi- 

 dered by various authors to be allied to them, few of which are 

 considered by Prof. Seward to have any real affinity with them 

 a Short account of the recent Lycopodiales, foUowed by a considera- 

 tion of the fossils Pleuronieia, Lycopodites, Selaginellites, Lycostrobus, 

 Poecilitostachys; 102 pages are devoted to the consideration of 

 Lepidodendron, in its various forms of preservation; Sigillavia, Stig- 

 niaria, and the Bothrodendreae are dealt with in 70 pages; Lepido- 

 cavpon and Miadesinia conclude the Lycopods; a short account of 

 the recent ferns preceeds the treatment of the fossil Osynimdaceae, 

 Schi'saeacae, Gleicheniaceae , Matonineae, Hymenophyllaceae, Cyathea- 

 ceae, Polypodiaceae and Dipterinae ; a number of genera are dealt 

 with in the chapter on fossil Mnrattiales; the Psaronieae and the 

 Ophioglossales have each a chapter; ''Coenopterideae'^ is the new 

 name proposed by Prof. Seward to cover the Botryoptereae, and 

 the Zygoptereae, to which 40 pages are devoted; the Hydropieri- 

 deae and Sagenopteris conclude the ferns; the last chapter deals 

 with a large number of genera ofimpressions of ferns, P/m(iosp^r;7?s^ 

 and incertae sedis. 



The book concludes with a long and useful bibliography. 

 Nearly all the known species of any importance are dealt with 

 under the family to which Prof. Seward considers that they be- 

 long, and prefacing many of them are useful lists of synpnyms. 

 The book is planned to give a reliable account of all fossil plants 

 rather than to collect evidence in suppo.rt of any particular theor}" 

 or view; it is consequently impossible to give a short resume of 

 its Contents. Wide research, and sound, moderate views mark the 

 treatment throughout, and the book is one that every advanced 

 Student of fossil plants will find constantly of use, in study or 

 research work. M. C. Stopes."

The authors obtained in Japan mineral concretions of Creta- 

 ceous age, which contained the petrified debris of a mixed flora. 

 From their material they describe a selection of plants from Fungi 

 to Angiosperms. 



Roughly speaking, the flora seeras to have consisted of about 

 one-third Angiosperms, slightly more than one-third Gymnosperms, 

 and the rest of ferns and lower plants. The anatomy of the early 

 Angiosperms being such a desideratum in botany, their presence 

 in the petrifactions renders them doubly interesting, and particu- 

 larly when they are found in so evenly balanced a mixed flora. 



The plants described are as follows: 



Petvosphneria japonica, gen. et spec. nov. A fungus which has
