are found ca. 50 species of plants and animals (excl. mosses and 

 molluscs). 



In the Portlandia arctica zone arctic and subarctic species 

 are in majority, e. g. Betula Hana, Salix herbacea and 5. polaris. 



In the fluvioglacial layers the plant remains are all arranged 

 according to weight and size of grains; thus the clay mainly con- 

 tains mosses, the sand layers amber and seeds. Among the flowering 

 plants were both arctic and subarctic {Bettila nana, Salix herbacea, 

 S. polaris, Dryas octopetala etc.) and temperate species {Limnanthe- 

 mum iiyuipJiaeoides, Brasenia purpiirea etc.). They have been washed 

 together from different places and are probably of very different 

 ages. Among the temperate plants were several species characteristic 

 of the amber-and-pin beds: Brasenia pnrpurea, Potentilla anserina, 

 Ajuga reptans, Ranunculus repens — and it is probable that the 

 plants in question are really washed together from amber-and-pin 

 layers, as they were found among fragments of amber and small 

 pieces of wood. 



The author is giving a list of all the species found at the 

 locality. C. Ferdinandsen.

Concerning the geological conditions at Skaerumhede found 

 during a boring made in 1905 closer informations are to be found in 

 the above mentioned paper by N. Hartz. Also the remains of mosses 

 were found only in the Portlandia arctica zone and in the flu- 

 vioglacial deposits. In the first most of the plant remains consist of 

 mosses, the pins and seeds being rather scarce. The Mitsei pleuro- 

 carpi are here in the majority, both as regards species and individuals. 

 The most common species is Amblystegium giganteum, found in all 

 the samples and forming in many of them the main part; together 

 with this species other Amblystegium species {A. scorpioides, A. 

 turgescens, A. fluitans etc.) are oecurring. The Musci acrocarpi are 

 represented by Ditrichum flexicaule and Swartsia montana. Astro- 

 phyllum cuspidatum is identified in most of the lower layers. 



In the fluvioglacial la3*ers the moss remains oeeur rather scar- 

 cely, especially the Musci acrocarpi, while the M. pleurocarpi are 

 represented by as many species as individuals. The remains 

 having been violently rubbed by sand and gravel, the stronger 

 leaves of the M. pleurocarpi, especially of the many Amblystegium 

 species, have proved to be more resistant than the often more deli- 

 cate leaves of the M. acrocarpi. In the whole most of the mosses 

 are found at clayey levels. 



There are found in the Portlandia arctica zone 68 species of 

 mosses and in the fluvioglacial layers the same number, with few 

 exceptions the same as were found in the Portlandia zone. They 

 have obviously been washed together from different spots, but 

 indicate a climate similar to that of northern Europe and Asia. 

 The species are both arctic and temperate and still living in the 

 northern regions of Europe and Asia. C. Ferdinandsen.
