series of fossil plants from Risdon, Geilston Quarry, and 

 Shoobridge's Limekiln, &c., near Hobart. The first is 

 one of the best localities for the Travertin containing the 

 leaves. In the British Museum there is also a series of 

 fossil plant-remains, which are labelled ' JErebus and 

 Terror,' and were collected during the exploring voyage 

 of those vessels to the Antarctic Seas by Dr. C. M'Cor- 

 mick, who was attached as Surgeon and Naturalist to the 

 Erebus. The fossil plants I examined came from the 

 Tertiary Travertin, which is so extensively developed in 

 the neighbourhood of Hobart Town. Finally, I have also 

 examined the figures (afterwards reproduced) in R. M. 

 Johnston's Paper (' Notes showing that the Estuary of the 

 Derwent was occupied by a Freshwater Lake during the 

 Tertiary period.' Proc. Roy. Soc. Tas., 1881, pp. 1-21 

 [5 plates, sections ; and 6 plates, containing 102 figures)], 

 with the view of enlarging the knowledge of this interest- 

 ing fossil flora. It contains till now 35 species, which are 

 distributed into 21 genera and 17 families. Of the species 

 I have to mention — Araucaria Johnstoni (V. Mueller), 

 Myrica Eyrei, closely allied to M. salicina of the European 

 Miocene ; Betula Derwentensis, corresponding to the 

 Miocene B. Brongniariii ; Alnus Muelleri, nearly allied 

 to the Miocene A. gracilis ; Quercus Tasmanii, like the 

 Q. PalcBococcus of the fossil flora of Radoboj ; Fagus 

 Risdoniana, nearly allied to F. Deiicalionis ; Salix Cor- 

 micMi, closely allied to S. varians ; Cinnamomum Wood- 

 wardii, allied to the Miocene C. Scheuchzeri ; Lomatia 

 prcB-longifolia, allied to Z. borealis of the European, and 

 to L. Torreyi of the American Tertiary flora, as well as 

 to the living Australian L, longifolia ; JDryandroides 

 Johnstoni, referring to living species of Bnnksia and 

 Brynndra ; Coprosma prce-cuspidifolia, the ancestral 

 species of the living C. cuspidifolia of Australia ; Ecki- 

 tonium obscurum, allied to E.macrospermum of the European 

 Miocene flora ; Elceocarpus Bassi, nearly allied to the 

 Miocene E. Albrechti ; Sapindiis Tasmanicus, nearly 

 allied to S. falcifolius of the European Miocene ; Cassia 

 Flindersii, allied to C. ambigiia of the same strata. 

 Besides these, species of Apocynophyllum, Cordia, Premna, 

 Sapotacites, and Ceratopetalum occur. This flora contains 

 more characteristic genera referable to the living Australian 

 flora than that of Dalton, in New South Wales, especially
