464 W. Carruthers — Review of Fossil Botany. 



A plant from Burntisland — Lepidophloios brevifoUitm, 'Williamson — is described 

 at length, and reasons are given for uniting the genera Diploxylon, Anabathra, 

 Lomatophloios and Leptoxylo7i.

 Coal-measures. Proc. Roy. Soc. vol. xx. pp. 435-438. 



The author refers to investigations which induce him to propose a new genus 

 Astrotnyelon for Calamite-stems already figured by him, to change his Dictyoxyloii 

 radicans into Amyelon radicans, and which show that Astcrophyllites is not the 

 branch of a Calamite. He also refers to stems of petioles from Burntisland, on which 

 he proposes to found two new genera, Ajpexylon zx\d,Edraxyloji, as well as to the 

 occurrence of Zygopteris Lacattii in Lancashire.
