Notes on some Additional Fossils collected at Seymour 
Island, Graham’s Land, by Dr Donald and Captain 
Larsen. By George Sharman, Esq., and E. T. Newton,

Dr Donald, who sailed on board the “ Active ” in the voyage of 
1892-3, has given a short account of the discovery of a number of 
fossils by Captain Larsen on Seymour Island, to the north of Snow 
Hill, in January 1893 ( Geographical Journal , vol. ii. p. 438, 
1893) . Some of these fossils were sent to Professor James Geikie, 
and at his request we gave an account of them to the Royal Society 
of Edinburgh, June 4, 1894 {Trans. Roy. Soc. Edin ., vol. xxxvii. 
p. 707 ; see also Dr Murray, Geog. Journ ., vol. iii. p. 11, note, 
1894) . The fossils do not appear to have been found in situ. 
Captain Larsen reports of the locality “ that he found no traces of 
vegetation there, the surface being formed of volcanic debris and 
numbers of these fossils ” (Dr Donald’s notice, p. 438, loc. cit.). 
The condition of the fossils, however, would seem to indicate 
that the mother rock from which they were derived could not be 
at any great distance from the spot where they were picked up. 
As the few species of Mollusca represented by these fossils 
seemed to us to find their nearest allies among Lower Tertiary forms, 
and to be near to certain species known from Patagonia (Darwin, 
Geol. Obs. Sth. Am., 1846), we were led to conclude that these new 
discoveries indicated the occurrence of Lower Tertiary rocks in 
Seymour Island. 
Two of the fossils examined by us were sufficiently distinct from 
known species to justify their receiving new specific names. One 
of these was a large Cucullcea resembling Cucullaia alta, Sow., 
from tertiary beds of Santa Cruz, and C. decussata , Sow., from the 
Lower Eocene of Britain, but, as it differed in certain points, it has 
been named C. Donaldi. 
The second new form, called by us Cytherea antarctica, has some
