THE CARBONIFEROUS ROCKS OF CANONBIE, DUMFRIESSHIRE, ETC. 747 



separating fragmentary examples of the upper part of Sphenopteris crassa, L. and H., and 

 Sphenopteris pachyrrhachis, Gopp. 



I now find I was in error in formerly regarding these two species as possibly being 

 referable to Sphenopteridiuni dissectum, Gopp., sp. 



Locality. — Glencartholm, Eskdale.

 figs. 7-8. 



Remarks. — I have referred elsewhere to the almost certain error in the locality 

 given by Lindley and Hutton for their Sphenopteris obovata and Sphenopteris excelsa* 

 There is almost certain evidence to show that they came from the neighbourhood of 

 Edinburgh, and this view was strongly held by the late Mr Howse, Newcastle. 



From the examination of many specimens I am now perfectly satisfied as to the 

 identity of Sphenopteris excelsa with Sphenopteris obovata. 



Sphenopteris obovata, L. and H., was extremely common at Glencartholm. 



Locality. — Glencartholm, Eskdale. 



Sphenopteris Hibberti, L. and 11., var.

1883. Sphenopteris Hibberti, var. Kidston, Trans. Roy. Soc. Edin., vol. xxx. p. 538. pi. xxx. fig. 1. 



Remarks. — It is quite possible that the fern I have figured as Sphenopteris 

 Hibberti, var., may be a form of Sphenopteris obovata, L. and H. I have not yet met 

 with any specimens which could be referred with certainty to Sphenopteris Hibberti, 

 L. and H., and hitherto have been unable to discover the type of the species. 



Locality. — Glencartholm, Eskdale.
