Tivo Fossil Plants from Dundas. 161 



The general form of the frond of Oleandridiuvi vittatufu, 

 Brongniart, as figured by FeistmanteP from the Indian Upper 

 ■Gondwanas, agrees closely with that of the Dundas specimen, 

 but the venation is less inclined and more widely spaced. 

 Zeiller- has figured a leaf from Sang-Sen which he refers to Tceiiiop- 

 teris McClellatidi^ Oldham and Morris, which in closeness of 

 venation approaches our specimen. In this connection it may 

 be pointed out that Zeiller's figure shows an almost entire 

 absence of bifurcation of venation, whereas in the original figures 

 that condition is much more frequent. '' 



It is, in my opinion, very likely that when better preserved 

 specimens are found this will prove to differ specifically from the 

 N. S. Wales and Queensland forms, but till then nothing definite 

 can be said. 



Baiera, sp. 



The specimen is less definite than the Oleandridium^ and it is 

 impossible to arrive at the dimensions of the perfect leaf. The 

 distal portions, up to 55 mm. in length represent si.x of the leaf 

 divisions. It does not appear to have been so dichotomous as 

 either B. ginkoides or B. ipsviciensis^ Shirley, which also appear to 

 have been finer veined.^ It also is widely separated from Tenison 

 y^oodiS, Jearipau Ha biden^ {Gi?ikgo bidens, Shirley). The Dundas 

 specimen may be compared with Feistmantel's B. schetiki^' from 

 Indwe, Upper Karoo formation. In this form the leaf divisions 

 are very much longer and narrower than those of our specimens 

 appear to be. There can, I think, be little doubt that this 

 species is distinct from any Australian form hitherto described, 

 though it is impossible to draw up a satisfactory diagnosis from 

 the limited material. 



Both specimens were found associated with Psilichthys selwyni, 

 T. S. Hall, at Carapook (Muntham), County of Dundas, Victoi'ia.
