82 RUFFORDIA. 
V. 2166. Pl. V. Fig: 1. 
Corresponds closely with V. 2157, but differs in the greater size 
of the frond, of which this is a fragment, and in the fact that the 
ultimate segments are slightly broader. Closely associated with 
the fragments on this piece of rock are portions of what may 
possibly be the rhizome of the same species. Cf. Pl. IV. (V. 2157) 
and Pl. V. Fig. 2 (V. 2156). Ecclesbourne. Rufford Coll. 
V. 2156. Pl. V. Fig. 3. 
In Fig. 34 we have an exceedingly graceful ?frond of roughly 
pentagonal form and compact habit. It represents a further 
increase in the breadth of the ultimate segments, but is still 
entirely in accord with the general character of the species. 
Fig. 38 shows part of a large frond with a well-marked flexuous 
rachis. Cf. Pl. V. Fig. 2 (V. 2155a). Ecclesbourne. Rufford Coll. 
V. 2155. Pl. V. Fig. 2. 
Very similar as regards breadth of segments to V. 2157, Pl. IV. 
The rachis is distinctly flexuous, and the general habit of this 
and other specimens is strikingly similar to that of Anemia 
adiantifolia, Sw.

V. 2243. Pl. V. Fig. 4. 
A slight increase is apparent in the breadth of the segments, and 
some of them appear to be obtusely rounded at the apex rather 
than acute. In each lobe of the pinne are several palmately- 
placed veins. The first glance at this specimen and Fig. 2 of 
the same plate (V. 21552) suggests two specific forms, but on 
close inspection of the two specimens a difference in breadth of 
the ultimate divisions appears to be the only real distinction, 
and, in view of the correspondence in habit, this alone is hardly 
of sufficient importance to necessitate a separate species. Lccles-

This affords a good example of a small and compact type of 
?frond, which differs only in size from the larger and commoner 
specimens. On the same piece of rock is a piece of rhizome,
