of the Clyde and other localities in Scotland, where they 

 are often of larger size than in the post-glacial deposits of 

 Sweden. 



That a similar marine fauna lived in the Polar Sea, when 

 that sea was more extensive than now, and covered lands 

 that now form the northern coast of Siberia, is demonstrated 

 by the explorations of NordenskioJd in the " Voyage of the 

 Vega." 



In the upper earthy l-Ajer of the tundra, on the banks of 

 the Yenisej, he discovered numerous species of shells, some 

 of which are common species in the Uddevalla beds, as 

 My a truncata var. Uddevalensis, Tellina lata, Trichotropis 

 horealis, and Natica lielicoides. 



Before concluding, it may not be uninteresting to record 

 the plants seen and gathered on the rocky knoll near the 

 last deposit, on 21st March, 1884. They are all common 

 British plants, except the Hepatica triloba, which is not an 

 inhabitant of the British Isles. 



The Sloe, Prunus spinoza, was in flower; the rock was gay 

 with the numerous white blooms of Saxifraga granulata 

 — the following were also in flower : Anemone nemorosa, 

 A. hepatica, L. (Hepatica triloba), Orohiis tuberosus, Sedum 

 acre, Leontodon taraxacum, a large lilac flowered Viola 

 (canina?), Viola tricolor, Convallaria majalis (not yet in 

 flower) ; and in the meadows below grew the Caltha palus- 

 tris with large corolla. 



In the following list of Uddevalla fossils, which have been 

 kindly identified for me by R. D. Darbishire, Esq. (the 

 result of one day's visit), I have, for the sake of convenience, 

 made use of the nomenclature and the synonymic list of 

 the late Dr. J. Gwyn Jeffreys, published in the Report of 

 the British Association for the Advancement of Science, 

 for 1863.
