These leaves are no doubt the same as those which have been 

 xecorded from time to time as Zeugophyllites elongatus. Their 

 sjstematic position is a matter of uncertainty, and they have been 

 compared with N cerjfjcrathiopsis, a memljer of the Cordaitales and 

 also by some authors ^\■ith members of the Ginkgoales.

CONCLUSION. 



In concluding the description of the flora of the Ipswich and 

 WaUoon Series it may be stated that a detailed discussion of the 

 flora and a comparison with other floras is being prepared by the 

 author. The results of this work so far obtained indicate that 

 there are decided differences between the floras of the two Series, 

 and that the flora of the Ipswich Series is of a distinct!}' older 

 facies than that of the Walloon Series. It is also clear that the 

 Walloon Series must be regarded as Jurassic, probabh^ homotaxial 

 with the Liassic or Lower Oohte of Europe ; while the Ipswich 

 Series must be regarded as Triassic, perhaps homotaxial with the 

 so-called Rhaetic Beds of various areas, but possiblj- older.
