(V. 2120), and the less pointed form of V. 2123c (PL III. Fig. 3). 

 Ecclesbourne. Rufford Coll. 



V. 2123^. PI. III. Fig. 3. At the upper end of the specimen 

 there is part of a rachis with five pinnae attached ; the rest of the 

 slab shows several imperfect pinnae with gradually tapered tips ; 

 the tips seem to be intermediate in form between those of 

 V. 2227 (PI. III. Fig. 4) and V. 2363 (PL III. Fig. 2), 

 V. 2123, etc. Ecclesbourne. Rufford Coll. 



V. 21253. PL IV. Fig. 1. A young frond, 25cm. long; 

 cf. V. 21233, etc. Pinnae approximate, very gradually tapering 

 distally. The pinnae are broadest in the middle of the specimen, 

 and narrower towards either end ; at the lower end the pinnae 

 are narrower and less closely arranged, agreeing with those of 

 V. 2262 (PL III. Fig. 1). Compare also V. 2898 and Fontaine's 

 pi. Ixxi. fig. 2. Ecclesbourne. Rufford Coll. 



V. 21256-. PL IV. Fig. 2. Rachis 33 cm. long. Pinnae 

 alternate and opposite, rachis depressed, the points of attachment 

 of segments clearly shown, apical portions not preserved ; broadest 

 pinna 7 mm., narrowest 5 mm. Venation distinct. Cf. V. 2123, 

 V. 2125a, etc. Ecclesbourne. Rufford Coll. 



V. 2123. PL IV. Figs. 4 and 5. 35 cm. long. Eachis well 

 shown, the longitudinal irregular striations distinct ; these pro- 

 bably indicate strands of hypodermal sclerenchymatous tissue. 

 Tips of pinnae not seen, but bases very distinct ; in Figs. 4 and 5 

 the surface and oblique insertion is easily recognized, also in some 

 pinnae the very slightly broadened base. In the lower part of 

 the frond the pinnae are nearly at right angles to the rachis, but 

 more oblique towards the upper end. Veins numerous and fine, 

 and in many pinnae clearly shown. Ecclesbourne. Ruffurd Coll. 



V. 2925. PL IV. Fig. 3. Specimen very similar to V. 2125 ; 

 hut piunse farther apart, and in this respect identical with the 

 lower portion of V. 2123rt. In addition to the larger example, 

 there is a very small fragment on one side of the slab, which is 

 evidently the tip of a frond (PL IV. Fig. 3) ; in this the segments 

 are closer together and more oblique to the rachis than in 

 V. 21253, and more like V. 21233 and V. 21253. Ecclesbourne.
