Remarks. Sphenopteris dichotoma, Gutbier (Vers. des Rothl. in Sachsen, 

 p. 11. pi. viii. fig. 7), is a distinct species from that to which Althaus applied his 

 name Gutbier's fern has since been distinguished as Sphenopteris semialata 

 by Weiss (Flora d. jiing. Steink. u. d. Eothl. p. 55). The counterpart of the 

 type, figured by Althaus (' Palaeontographica,' vol. i. pi. iv. fig. 1), is in the 

 Collection.

Remarks. Schimpert unites this species with Sphenopteris dichotoma, 

 Althaus, but from a careful comparison of the two types, which are in the 

 Collection, I find they must be kept separate.
