are striated, the ridges are smooth and not very prominent for 

 the most part, though at one end they are fairly sharp, and 

 agree more closely with the deeply grooved intern odes of the other 

 fragments of stems scattered about on the same specimen.

Pith (?)-casts. 



V. 7100. A piece of sandy shale, on which are scattered 

 a number of stem-casts. One of the longest of these is 12'5 cm. in 

 length, and 9 mm. across. There are no clear signs of any constriction 

 into nodes and internodes. The cast is sharply ridged, the grooves 

 between the ridges are broad and longitudinally striated. For 

 reasons already explained I am inclined to regard these and similar 

 casts as possibly pith-casts of Schizoneura. 



Bardwan Coalfield. 



V. 7100#. This specimen contains several fragments of 

 prominently ridged internodes similar to those above described. 

 No definite evidence as to nodes can be found, although one cast 

 is 15 cm. long. The nodal characters are possibly absent as the 

 result of bad preservation. 



Bardwan Coalfield. 



V. 6478. A broad cast of a stem, 15cm. long and 35cm. 

 across. The specimen shows a single node. There are no scars 

 to be seen, and the ridges of the internodes are continuous at the 

 node. It is impossible to say definitely whether such a specimen 

 is a cast of Schizoneura or Phyllotheca. Its resemblance, however, 

 to the other casts described here suggests provisionally the former 

 genus rather than the latter. Feistmantel (80), pi. va, fig. 3, has 

 figured a similar specimen.
