INTRODUCTION. 



THE following Catalogue is an enumeration of the Palaeozoic Plants, 

 with their synonymy, contained in the Collection of the Department 

 of Geology and Palaeontology, British Museum (Natural History). 



The classification employed is that at present adopted by the 

 majority of Palaeophytologists, with slight modifications, and requires 

 no special remark. The plants are treated under the four great Geolo- 

 gical Divisions of the Palaeozoic Rocks, viz., Permian, Carboniferous, 

 Devonian, and Silurian. 



In the Botanical arrangement the Family is first given, following 

 which is the Genus, with its author's name, date of its publication and 

 reference to the work in which it first appeared. The specific name 

 adopted follows, with its synonymy : the oldest name of the plant in 

 question being used. When, however, any doubt exists, the oldest 

 name is adopted about which there is a certainty as to the plant 

 meant. For the facility of finding a reference, the synonyms are 

 given under each species in the alphabetical order of the authors' 

 names and not in order of date. 



A list of the works consulted, with the dates and places of their 

 publication, will be found at the end of the Catalogue, by referring to 

 which the date of any particular reference can be ascertained. 



Tn the Index, the accepted names of both genera and species are 

 printed in ordinary type, the synonyms in italics. 



In the preparation of this Catalogue I am indebted for assistance 

 given in various ways, to the Officers and Assistants of the Geological 

 Department, and more especially to Mr. Robert Etheridge, Jun., for 

 his care in the revision of my references to authors, &c. ; to Mr, 

 J. McMurtrie, Radstock, and the Officials of the Bath and Bristol 

 Museums; Mr. R. Howse, Newcastle-on-Tyne ; to Dr. A. Geikie, 

 F.R.S., Director-General of the Geological Survey of Great Britain ; 

 and Mr. G. Sharman, Museum of Practical Geology, London ; to 

 Dr. R. H. Traqnair, F.R.S., Museum of Science and Art, Edinburgh ;
