372 MR ROBERT KIDSTON ON THE FOSSIL FLORA OF THE 



I have been led to suspect that perhaps Pec. villosa, Brongt., should be referred 

 to this species. 



Localities : — Radstock; Braysdown Colliery; Upper Conygre Pit; Camerton. 



Pecopteris Cistii, Brongniart. 



Pecopiteris Cistii, Brongt., Hist. d. veget. foss., p. 330, pi. cvi. 



Remarks. — I only know this species from Brongniart's figures and descrip- 

 tion. Of the two specimens figured by him, one came from Dunkerton, near 

 Bath, and the other from Wilkesbarre, Pennsylvania. 



Dunkerton Pit is now closed, but I have carefully examined other localities 

 where the same coals are worked in the hope of rediscovering this species, 

 but have -hitherto been unsuccessful. Lesquereux says in regard to Pec. Cistii 

 — " Though I have seen many fragments referred to it, I have never been able 

 to positively recognise in any the characters indicated by the author."* I can 

 fully endorse this statement, for, though I have also seen specimens labelled 

 " Pec. Cistii" none of them possessed characters entirely in agreement with 

 Brongniart's description, and were, 1 am afraid, only Pec. oreopteridia. 



The type from Dunkerton, which belonged to the Museum of the University 

 of Oxford, appears to have been lost or mislaid, for, when visiting that collection 

 a short time ago, we were unable to discover it. 



Locality : — Dunkerton (Br'ongniart). 



Pecopteris Bucklandii, Brongniart. 



Pecopteris Bucklandii, Brongt., Hist. d. veget. foss., p. 319, pi. xcix. fig. 2. 



Pecopteris Bucklandii, Grand' Eury, Flore Carb. du Depart, de la Loire, p. 75. 



Pecopteris Buclclandii, Scliimper, Traite d. paleont. veget, vol. i. p. 504. 



Pecopteris Bucklandii, Weiss, Foss. Flora d. jiingst. Stk. u. d. Rothl., p. 64. 



Pecopteris pseudo-Bucklandii, Germar, Vers. d. Steink. v. Wettin u. Lbbejun, p. 106, pi. xxxvii. 



Remarks. — This species is very rare, but a few examples have been collected 

 at Camerton — the original locality. 



It is very doubtful if the fern figured as Pec. Bucklandii by Lindley and 

 HuTTONt really belongs to this species. If their figure is correct, I am 

 inclined to think that it does not. Stur suggests that Lindley and Hutton's 

 plant may perhaps be his Hawlea Schaumberg-Lipjwana, but this is also very 

 doubtful.^: 



Locality : — Camerton.
