98 CLADOPHLEBIS. 
V. 2202¢ and V. 2373. Terminal portions of a frond. Pinnee 
opposite or sub-opposite. The rachis appears to be winged. 
Pinnules alternate, dentate towards their apices, with clearly 
marked venation. 
The larger pinnules are not quite so acutely pointed as in the 
majority of specimens, but the terminal parts of the pinne show 
the usual serrate form. Cf. the apical portion of V. 2794, Pl. VIII. 
Ecclesbourne. Rufford Coll. 
V. 22024. Another terminal piece, but with shorter and more 
falcate pinnules. Ecclesbourne. Rufford Coll. 
V. 2206. The two specimens with this registered number show 
pinnules with distinct venation; some of them are falcate and with 
dentate margin. Here, as in many other specimens referred to 
this species, there is a variation in the shape of the pinnules, some 
being faleate, others straight, but all attached to the axis of the 
pinna by the entire base. Ecclesbourne. Rufford Coll. 
V. 2225. Curved rachis; pinne with clearly preserved pinnules 
showing a distinctly dentate margin. Ecclesbourne. ufford Coll. 
V. 2372. Portion of a frond, 10 cm. long. Pinnules distinct; in 
some the falcate character is well shown, and in those of the 
lower pinne there are signs of a dentate margin. 
V. 2372a. Broad curved rachis. Some of the large pinnules 
distinctly faleate with dentate margin. Ecclesbourne. Rufford Coll. 
V. 2175, V. 2187, V. 2191, V. 2201, V. 2217, V. 2220, 
V. 2226, V. 2371, V. 2378, V. 2379, V. 27386. Ecclesbourne.

52942. Ecclesbourne. Presented by J. F. H. Peyton, Esq., 1886. 
These specimens are referred to the same species, C. Albertsi. 
Some of the larger pinne, e.g. V. 2871, suggest Alethopteris 
Tuttoni, Schimp.,' and possibly this species may have to be 
included as a synonym under C. Albertsi (Dunk.).
