46 DIOONITES. 



V. 2823. PI. II. Fig. 3. 



Cf. V. 1069. Cycadites Saportce. Small specimen, evidently 

 close to the frond apex. The pinnae are much more oblique 

 and decurrent than in the previous example. Ecclesbourne.

V. 2821. Fi. 2. 



. 



Imperfectly preserved piece of rachis with portions of pinnae 

 on one side ; some of the pinnae have well-marked venation and 

 acute tips. The figure shows some of the more perfect apices. 

 The pinnae have a breadth of about 2 mm., and each is traversed 

 by numerous veins, in some of the segments as many as ten may 

 be counted. A comparison of this specimen with V. 3218 (PI. II. 

 Pig. 6) shows some fairly striking differences, and it is not 

 improbable that we have to deal with two specific forms ; in 

 V. 2821 the veins are more numerous, and the pinnae are shorter 

 and proportionately broader than in the other examples referred 

 to this species. Ecclesbourne. Rufford Coll. 



FIG. 2. P Dioonites Dunkerianus (Gopp.). 

 Distal terminations of pinnae (V. 2821). 



V. 21240. Broad and flat rachis very like that of Cycadites 

 Saportee. On one side the long and narrow pinnae are fairly well 

 preserved, showing occasional signs of venation and a strong 

 convex upper surface. Ecclesbourne. Rujford Coll. 



V. 2127. Probably a portion of a frond near the apex. The 

 broad bases of the pinnae and their manner of attachment to the 

 rachis clearly seen. Ecclesbourne. Rujford Coll. 



V. 2361. Probably a fragment of this species ; broad pinnae. 

 Ecclesbourne. Rufford Coll.
