I. Introduction. ■ 



This paper records the results of a study of the fossil plants which 

 I have collected from the Pembrokeshire Coalfield during the last 

 two years ; of these the best specimens are now in the Sedgwick 

 Mnseum, Cambridge. 



I have confined my attention principally to the excellent coast- 

 sections between Tenby and Ragwen Point, where the coalfield is 

 eaten into by the sea along Carmarthen Bay ; and those on the 

 eastern side of St. Bride's Bay, from Talbenny on the south to 

 Newgale on the north. I have also collected from various colliery- 

 ' tips ' between Nolton and Newgale, and have worked much of 

 the sections where the Eastern Cleddau, the "Western Cleddau, and 

 the Daucleddau eat into the coalfield south-east of Haverfordwest. 

 These river-sections proved, however, to be very disappointing, 

 with the exception of that in the neighbourhood of Picton Point, 

 and in one or two other localities. 



I wish here to record my indebtedness to Dr. E. A. Newell 

 Arber, without whose aid this work would not have been undertaken. 

 It was at his suggestion that I first proceeded to Pembrokeshire, 

 with the view of studying the fossil flora of this portion of the 

 South Wales Coalfield. He has supervised the identification of 

 the plants, particularly affording me much help in the determina- 

 tion of difficult species, and has given me his advice throughout, 

 for which I return my sincere thanks. 



I also gratefully acknowledge the help which I have received 

 from various officers of H.M. Geological Survey, who have freely 

 given me information concerning the districts surveyed by them 

 during the last decade, and have kindly allowed me to examine
