Considering the results obtained from Slutemyr, it is pos- 

 sible that a careful examination of the W. banks of the Suiedal 

 lakes, and the fjeld-hights abutting on them might lead to 

 the discovery of a certain similarity between the alpine moss- 

 flora of the Filefjeld and that of the Dovrefjeld. 



Subsequently to the completion of our catalogue, Dr. Kiær 

 was kind enough to still further enrich this by the addition 

 •of notices respecting the mosses already collected on the File- 

 fjeld, drawn partly from his own list, partly from Professor 

 N. M. Blytts manuscript, and partly from the University her- 

 barium. We desire to express our sincere thanks for these 

 valuable communications. The norwegian collaborator desires 

 moreover hereby to express her best thanks to Professor 

 Norrlin of Helsingissa, the Rev. d Chr. Kaurin of Sande, Jarls- 

 berg, and to Dr. Warnstorf of Neuruppin for their freely- 

 afforded assistance in the determination of doubtful and un- 

 known species. 



As appears from the subjoined list there where discovered 

 in the summer of 1886 210 mosses at and around Maristuen. 

 Musci acrocarpi 134, musci pleurocarpi GO, Andreæaceae 4, 

 Spagnaceae 12. Meanwhile there are mentioned in Hartman's 

 Flora one species, Barbula mucronifolia, from Maristuen not 

 observed by us. Dr. Kiær makes mention of 29 species, of 

 which however only 3 are known for certain to have been 

 gathered on the above described area. The number of mosses 

 found at Maristuen is therefore 214, but if the addional 26 be 

 included, the number will amount to 240. Thus there occur 

 for certain over a superficial area of 48 km. 2 at Maristuen 

 214 species of mosses. 



If the claim be admitted to consider the above named 

 area as a well-defined locality of small size, and upon this 

 presumption to compare the proportions therein existing between 

 extent of ground and number of species with those given by
