base of each pair of pinnae. Mrs Scott ^ who has recently 

 described the sporangia of this species, speaks of one specimen 

 in which germinating spores were found. The same author 

 gives an account of some curious spindle-shaped bodies which 

 she found in association with S. burntislandica. The nature 

 of these organs is uncertain; Mrs Scott inclines to regard 

 them as glands borne in pairs on lateral pedicels of the 

 frond: she adopts for these the name Bensonites fusiformis 

 proposed by Dr Scott. If there is a reasonable probability, as 

 there certainly seems to be, in favour of connecting these organs 

 with Stauropteris, it is legitimate to question the desirability 

 of adding to the long list of names included in the group 

 Coenopterideae.

This genus was founded by Baily'' on fragments of a fern 

 from Carboniferous rocks in County Limerick, Ireland, charac- 

 terised by a peculiar type of fructification which he named 

 Corynepteris stellata. More complete examples of the same 

 genus have been described by Zeiller' from the Coal-field of
