 Mr. W. S. Dun, Palaeontologist to the Geological Survey, New South Wales, and 

 Sydney University Lecturer in Palseontology, has kindly supplied us with the 

 following list showing the distribution of the chief genera of this Antarctic flora 

 in Jurassic time : * — 



The close affinity of the flora to that of Australia and of India, shown on this 

 list, implies a land connection between Antarctica and Australia in Jurassic or Trias- 

 Jura time. 



At Snow Hill Island abundance of Cretaceous fossils, including numerous 

 Ammonites, were collected by Dr. Nordenskjcild's Expedition. These fossils imply 

 the existence of a mild climate, with comparative warm ocean cm-rents in the neigh- 

 bourhood of Snow Hill Island in Cretaceous time. The fossil plants Araucaria, 

 Fagus, &c., near to A. hraziliensis, unearthed by the Nordenskjold Expedition at 

 Seymour Island, adjoining Snow Hill Island on the north-east, prove that these 

 mild weather conditions were further prolonged into some part of Tertiary time, 

 probably Oligocene or Lower Miocene. In marine strata, also of Tertiary age, and 

 considered by Wilckensf to belong to Upper Oligocene or Lower Miocene, this

 Carboniferous and other rocks of Southern Brazil, as well as from Memoirs on the Argentine Republic.
