V. 2295. PL III. Fig 6. 



This specimen differs from V. 2731 in having the lower ? pinnae 

 in the fertile condition. The leaf lamina is considerably reduced, 

 and the individual sporangia may he made out here and there, but 

 without affording any reliable information as to the character of the 

 sporangial walls. Possibly expression should be given to the 

 smaller size of this and the preceding specimen by the institution 

 of a new species or variety, but I am inclined to attach great 

 importance to the fact that such a specimen as V. 2157, PI. IV. 

 shows the same habit and essential features as these smaller and 

 more delicate forms. There is a distinct resemblance between this 

 specimen and a fertile pinna figured by Fee l as Aneimiahotrys 

 aspera from Brazil. Cf. PL V. Fig. SA (V. 2156). Ecclesbourne.

V. 2160. PL Y. Fig. 5. 



This specimen shows very clearly the characters of a fertile 

 pinna. The general habit is much the same as that of PL V. 

 Fig. SA (V. 2156) and other specimens, but in this case, instead 

 of the sharp margins of the pinnules characteristic of the sterile 

 pinnae, we find a certain ragged appearance in the ultimate 

 segments, and irregular outlines to the blunt lobes. The surface 

 of the pinnules is marked by numerous round projections, which 

 are undoubtedly sporangia ; these cover almost the whole surface 

 of the ultimate segments, and, as far as it is possible to decide, 

 closely agree in their manner of occurrence with those of Anemia.

V. 2812. PL X. Fig. 2. 



This specimen I regard as part of a rhizome of Ruffordia 

 Gopperti; the surface has a rough appearance suggestive of 

 scaly hairs, and to parts of it are attached the lower portions 

 of petioles. On the same rock occur fragments of pinnaB of this 

 species. Ecclesbourne. Rufford Coll. 



V. 2731. PL X. Fig. 1. 



This larger piece of rhizome has already been mentioned in the 

 description of PL III. Fig. 5, which occurs in the same piece of 

 ironstone. The surface has the same characteristic roughness
