with it, seems to preclude the affinity of this organism with the 

 Algse, and brings it nearer to the genus in which it is provision- 

 ally placed. As I have no doubt of the identity of the Jarrow 

 with the Methil, Fife, specimens, I append Mr. Kirkby's name 

 to the species, and trust that it may not be an undesired synonym.

92.— Sphenopteris bifida, L. et H. Type specimen, E. F., pi. 53. 



Specimen on slab of freshwater limestone ; frond imperfect, 

 about three inches long; lateral pinnae or branches nearly 

 opposite each other, with secondary pinnae, bifurcating from 

 two to five times into long narrow pinnules. 

 Loc. — Calciferous sandstone series, Burdie House. {H.C. 189). 



Remarks. — This Type-specimen, from Burdie House limestone, 

 communicated to the authors of the "Fossil Flora" by Mr. 

 Witham, is very badly figured in their Plate 53, so that foreign 

 authors, as Stur, may be pardoned if they have failed in grasping 

 tbe characters of this species, and added new synonyms to an 

 already overburdened list. There are remains of three fronds, 

 or pinnae it may be, on this slab ; the upper one on the left being 

 on a different plane, and not connected with the main figure. 

 The pinnules are also broader than in Hutton' s figure and not so 

 wiry -looking, more regular and symmetrical. Hugh Miller's 

 figure quoted above, though somewhat smaller, gives a better 

 idea of the general appearance of this species. There can be no 

 doubt that Stur's two species quoted above are representations 

 of portions of the same species. I incline also to the opinion
