This work (which forms the 5th part of the Society for in- 

 vestigating the natural history of Finland) embraces the Lichen 

 Flora of Norway, Sweden, and Finland, extending into the Arctic 

 regions. It contains some prefatory remarks upon Lichens in 

 general, a list of the ])rinoipal published works and collections of 

 specimens, and a detailed account (with synonyms and critical 

 remarks) of 494 Scandinavian species. The whole number of 

 known Lichens is estimated by the author at 1499. Of tlie 494 

 Scandinavian species 27 are new. The author had access to the 

 herbarium of Acharius, which renders the synonymy very valua- 

 ])\v. There is an appendix relative to nine species which came 

 to lunul during the ])rinting of the book. There is one plate, 

 containing figures by tlm autlior of the spores of diflerent species, 

 amongst which those of Varicellaria, Nvl, are remarkable for their
