They include this genus in the Gleicheniacee. The nervation 
appears to be very imperfect, but the median vein is nearly 
always clear up to the apex of the pinnule. The figures 1, 2 and 
3 of these authors, and also some specimens figured by Ettings- 
hausen from the Cretaceous beds of Niederschéna, resemble rather 
closely some of the English examples of Cladophlebis longipennis.* 
In the absence of any satisfactory evidence in the Aachen species 
as to affinity with Gleicheniacee, and in the face of certain 
differences in the arrangement and shape of the pinnules in the 
English fragments, it is better not to commit oneself to a definite 
family, but for the present, at least, to retain the provisional name 
Cladophlebis. 
Cladophlebis virginiensis, Font.,? shows in some of its pinnules 
a form and venation very similar to those of C. longipennis, but 
there is probably no true affinity. Compare also <Alethopteris 
lobifolia, Schimp. (Phill.), Feistmantel, Fl. foss. Gond. vol. il. 
1880; p. 6; pl. in. fig, 1. 
The venation of this new species is perhaps hardly of the usual 
Cladophlebis type; in some respects, e.g. the acute angle at which 
the lateral veins spring from the midrib, it comes very near to the 
Sphenopteris pattern, but the habit of the plant and the mode 
of attachment of the pinnules are characters in favour of some 
other genus than Sphenopteris. 
V. 2204. Pl. IX. Figs. 1 and 1a. 
This single curved pinna shows very clearly the chief charac- 
teristics of the species. The veins are marked on the sandy 
matrix with special clearness, as shown in the single pinnule,
