abundant in the Transition Coal Measures. The figured specimen 

 from Kent is the first record from the Middle Coal Measures. In 

 these specimens the pinnules are rather smaller than those of the 

 fronds previously figured, but the nervation appears to me to be 

 identical.

Dictyopteris milnsteri is a characteristic plant in the Middle 

 Coal Measures of Kent. In other coalfields it also occurs in the 

 Transition and Upper Coal Measures. This species is a homceo- 

 morph of Jfeurojiteris lieteropliylta Brongn., from Avhich, however. 

 it is easilv distinguished bv the reticulate nervation.

This is a very rare and but little-understood species, of which 

 there are only three British records from the Middle and Lower 

 Coal Measures. It closely resembles certain species of JVeirro- 

 jAeris, especially iV 7 . obliqua Brongn., the chief distinctions 

 being that some of the lower nerves arise direct from the rachis, 

 and that the pinnules are attached by their whole base.
