PREFACE 



Since the publication of Mr. Kidston's Catalogue of the 

 Palaeozoic Plants in 1886, extensive additions have been 

 made to the collection in the British Museum, and much 

 research has been devoted to these fossils. The time seems 

 therefore to have arrived for a series of more detailed 

 Catalogues. The Glossopteris Flora has proved to be 

 especially important, and it is not only of great geological 

 and botanical interest, but also of practical value to the 

 prospectors for coalfields in India and the southern hemi- 

 sphere. As this Flora has not hitherto been the subject 

 of any comprehensive treatise, it is thus appropriately 

 dealt with in the present volume, which is the first 

 special Catalogue of Palaeozoic Plants issued by the British 

 Museum. The work has been prepared with much care 

 by Mr. E. A. Newell Arbor, who has been able to add 

 somewhat to the existing knowledge, which he has critically 

 summarised.
