These are situated between Darra and Oxley, near Brisbane. 

 They consist of fine whitish to yellow argihaceous sands, passing 

 down into sandstone and grits ; they rest on an eroded surface 

 of the Ipswich beds.* Skertchley regarded them as " very old 

 Eocene (Laramie beds)." From their general facies, however, 

 one concludes that they are the equivalent of the typical leaf- 

 beds of the older series of Tertiaries in other States. Shirley 

 has described from these beds leaves which he refers to 

 Sapindiis oxleycnsis, Ficns suhsycamoriis, and Myrica siib- 

 salicina.-f The most extensive piece of work upon this plant- 

 bed has, however, been published by PLttingshausen in a work 

 entitled " Beitrage zur Kenntniss der Kreidefiora Austrahens,"J 

 in which he describes 64 species of fossil plants. Such genera 

 as Banksia, Cinnamomitm, Dicmenia, and Eucalyptus can be 

 reasonably accepted, but others, as Querctis, may be open to 

 question. Ettingshausen places the horizon in the Cretaceous 

 series, but the presence of well-advanced types of eucalypts 

 and many of the genera and species found in Mid-Tertiary 

 beds elsewhere in Austraha, exclude it from so old a formation 

 as the Cretaceous. In this memoir Ettingshausen refers to 

 Darra as Warragh, a misnomer which also enters into his 

 specific references. The species oi Apocynophyllum here recorded 

 recall those of the Victorian Tertiary flora. 



Travertine Lake Deposits near Hobart, Tasmania. — The com- 

 pact travertine limestone of Risdon, Geilston, Sandy Bay, and 

 other localities near the mouth of the River Derwent contains 

 beautifully-preserved impressions of fossil leaves and fruits. § 

 From these beds we may cite Araucarites, sp., Notofagus 

 Risdoniana, Cinnamomum Woodwardi, Lomatia prcelongi folia, 

 Coprosma pracuspidifolia, and Apocynophyllum, sp. The Inilk 

 of the flora has been dealt with by Ettingshausen, || but, as with 

 the New South Wales fossils, the list apparently requires some 

 revision. 



Tertiary Plants of South Australia. — The dicotyledonous 

 floras of the Lakes Eyre and Tcjrrens districts also bear close 

 resemblance to the Maddingley, Berwick, and Vegetable Creek 

 plant-remains, and they arc, without doubt, fairly well 

 dev(;loped as a Tertiary flora.^ The list of plant-remains, 

 with localities given by Tate and Watt, are as under: —
