1. 'On the Fossil Flora of the Pembrokeshire Portion of the 

 South Wales Coalfield.' By Reginald H. Goode, B.A. 



Of the fifty-three determiuable species of fossil plants obtained 

 from the Pembrokeshire portion of the South Wales Coalfield, 

 three are new species. One may be referred to Linopteris bron- 

 gniarti Gutb., a plant which has not with certainty been found 

 before in Britain. 



From the pakeobotanical evidence it is clear that the so-called 

 ' Pennant Grit' of Pembrokeshire cannot be regarded as the 

 equivalent of the Pennant Grit of the main portion of the South 

 Wales Coalfield : for the plants indicate that these beds are 

 Middle Coal Measures, and do not belong to the Transition Series. 

 The Lower Coal Series also clearly belongs to the Middle Coal 

 Measures ; and the Settlings Beds, and perhaps the Falling Cliff 

 Beds as well, lie probably at a higher horizon than the Lower Coal 

 Series as developed farther east along the Saundersfoot coast, and 

 even possibly higher than the Timber Vein group. 



Until more plants have been obtained from the so-called ' Mill- 

 stone Grit ' of Pembrokeshire, it is impossible to fix definitely 

 the horizon of these beds from the paloeobotanical evidence. How- 

 ever, from the fossil plants obtained in the so-called ' Millstone 

 Grit ' of Monkstone Point, and in neighbouring beds belonging to 

 the Lower Coal Series, between which there is no apparent uncon- 

 formity, it is evident that these particular beds, assigned to tt.< 

 Millstone Grit, probably belong to the Middle Coal Measures. 



When the fossil plants which have been obtained from the 

 Pembrokeshire Coalfield are compared with those which have been 

 recorded from the main South Wales Coalfield, it is evident that 

 there are considerable differences in the occurrence of the species. 



Thirty-two fossil plants have been obtained from the Middle 

 Coal Measures of Pembrokeshire which have not as yet been
