make any definite statement as to venation, but in one place there 

 is an indication of crowded veins almost at right angles to the axis 

 of a pinna. 



A second example of what is regarded as the same type is shown 

 as a diagrammatic sketch in text-fig. 5. This specimen is from the 



Burghersdorp Beds of Lady 



Fig. 5.— Ean^opsis Hughesi, ^^^re ; the main axis is 38-5 



Feistmantel: reduced diagram, centimetres in length, and is 



showing the branching of the characterized by an apparent 



rachis. dichotomy near the base. The 



pinnae are less distinctly pre- 

 served than in the smaller 

 example ; one arm of the 

 forked rachis bears a portion 

 of a lamina, b^b centimetres 

 broad and 12 cm. long ; the 

 midrib is clearly shown, but 

 there are no signs of secondary 

 veins. The thicker lines in 

 the sketch indicate what are 

 believed to be the actual out- 

 lines of the segments, as at 

 a & b; in places the lamina 

 appears to be lobed, but the 

 brown iron-oxide stain repre- 

 senting the pinnae is too blurred 

 to enable one to make out the 

 form with any degree of cer- 

 tainty. Portions of lamina 

 on the rachis point to a de- 

 currence of the segments, as 

 in the impression shown in 

 PI. YI. 



In spite of the unfavourable 

 state of preservation of the 

 two specimens, there can be 

 little doubt as to their close 

 agreement, if not specific 

 identity, with Feistmantel's 

 species from the Middle Gond- 

 wana rocks of India. ^ The 

 resemblance as regards the 

 form and size of the segments 

 is complete, although it is impossible to say how far the venation- 

 characters are in agreement ; another common feature is the dicho- 

 tomous branching of the rachis as shown in text-fig. 5, as in several 

 •of Feistmantel's illustrations of the Gondwana plant.^ Feistmantel
