SPHENOrTERIS. 



In some respects S. polymorpha recalls S. lobi folia and S. alata 

 (see pp. 135, 138), but in the form of the terminal segment or 

 pinnule, and in the regularly bifurcating secondary nervation, it 

 does not agree with either of the Australian species. 



I have shown recently that this species occurs in the Newcastle 

 Series of New South Wales. Specimens from this locality are in 

 the Sedgwick Museum, Cambridge.

I regard M'Clelland's Pecopteris affinis, so far as one can judge 

 from Ids imperfect figure, to be probably identical with S. poly- 

 morpha, a view which Feistmantel 1 at one time shared, although at 



1 Feistmantel (80), p. 77.
