mens figured but there can be no doubt of its being a Comptonia. 

 A large number of the smaller leaves of the existing species are 

 counterparts of these Senonian forms, the most similar figured 

 specimen being the leaf shown on PI. 2, Fig. 1. 



This species differs decidedly from Dryandra cretacea Yelen., 

 which I would retain in the Proteacese, otherwise the authors com- 

 parisons are most fortunate and it is very probable that we 

 have in Comptonia fenera the Cretaceous ancestor of Comptonia 

 schrankii which is so common from the Eocene through the Mio-

A large-leaved and beautiful species of which Unger has figured 

 a perfect leaf from Sotzka, which is identical with, l)ut somewhat 

 larger tlian Xathorst's CJomptoniphi/llum naumanni from Japan. 

 These leaves are practically the counterparts of numerous leaves 

 of the existing species (cf. PI. 2, Figs. .'3, 4). Those which are 

 descril)e<l by L'liger from Kumi have a jn-olonged base, which the

 coiiipariM,,,. with Dryandra armata R. Br. of the exi.sting flora. 

 Hi- .oiiipariM,!! nr.t, hnwe\er, particularly fortunate as the latter 

 s[)ecies has leaves which incline to a runcinate form, while the basal 

 portion of the leaf is much more narrowly lobed, some of the lobes- 

 being several times longer than they are wide and separated by an
