The only remain.s of animals hitherto recorded are an Esf/wria and two- 

 Labyrinthodonts, Ilrdc/ii/ajis /oticrjitt and an nnde.scrilied 1'orm formerly referred to 

 Air/ici/omiirus. 'J'iie only European )j;enns allied to JJrdc/ii/ojt.s is of Oolitic age. 



The most abundant of the above-named fossils are (i/o.isopfm'.t and I'lrfifirdria.. 

 With the exception of X'li'i/fp-rdf/iinji.^in all the cycads and conifers are of excessive 

 rarity. More than one-half of the species known are ferns with simple undivided 

 fronds and anastoiuosini,' venation. 



For many years I'luropean palreontologists generally classed this llora as 

 Jura.'isic. •' This was the view accepted by l)e Zigno and Schimper, and^ 

 though with more hesitation, by Ihinbury. The species of 1 /ii/lluf/iccd, Ale- 

 tliopfcrix (or Pccopfcris), and (rlnssapfrri'ti (allied to Sdi/niopffris) were considered 

 to exhibit marked Jurassic allinities. It was generally admitted that the Damuda 

 tlora resembles that of the Austr'ilian coal-measures (to which I shall refer 

 presently) more than it does that from any known luiropean formation ; but the 

 Australian plants were also classed as Jurassic. There is no reason for supposing 

 that the more recent discoveries of Damuda plants would have modified this view; 

 the identification of such forms as true Scu/enopferis Rnd the cycads Pterophyllnm 

 and Anomozmnitcs would assuredly have beeu held to contirm the Jurassic age of
