difficult to determine the position of the specimen which 

 Schimper has named Goniopteris brevifolia, but I have col- 

 lected specimens at Radstock which do not appear to me to 

 differ from Schimper's species (as far as I understand it), 

 which are evidently referable to Pecopteris 7nilto7ii. 

 IV. The Fossil Flora of Great Britain ; or figures 

 and descriptions of the vegetable remains found in a 

 fossil state in this country.— By Lindley & Hutton. Vol. 

 i, 1831—33; vol. ii, 1833—35 ; vol. iii, 1835—37 ; London. 



This work contains very few records of Yorkshire Coal 

 Plants. The following are figured : — 

 AsterophyUites galioides. Vol. i, pi. xxv, fig, 2. ' Barnsley 



Coal Field.' 

 Lepidostrobus ornatus. Vol. i, pi. xxvi. 'Barnsley Coal Field.' 

 Ha Ionia gracilis. Vol. ii, pi. Ixxxvi. Low Moor. 

 Calaviites verticillatus. Pi. cxxxix. From Hound Hill, near 



Pontefract. 

 Tiigonocarpum oblOfigntn. Vol. iii, pi. cxciiic. From Hound 



Hill, near Pontefract. 

 Calamites inequalis. PI. cxcvi. From Sandstone Quarry east 

 of Sheffield. 



From the figure of Calamites inequalis, it is impossible to 

 form any opinion of the value of this species, which appears 

 to have been founded on a badly-preserved example. 



On March 8, 1849, Mr. Henry Denny read a paper before 

 the Geological and Polytechnic Society of the West Riding 

 of Yorkshire, entitled 'A Glance at the Fossil Flora of the 

 Carboniferous Epoch, with special reference to the York- 

 shire Coal Field.' In it he figures a specimen of Lepido- 

 phloios, under the name of Halonia tuberculosa, shewing the 

 bifurcation of the stem and the Halonian branches attached. 

 More recently this specimen has been figured by Prof. 

 Williamson in his twelfth memoir " On the Organization 

 of the Fossil Plants of the Coal Measures."!
