HAB. On rocks upon the highest summit of Ben Nevis in 

 Scotland, at the eastern end. Plentiful on Ben-y-mac- 

 Duich and other mountains of the great Cairngorum 

 range. 



The present fine species has in Britain been only found at 

 the above mentioned stations. On the most elevated of the 

 Swiss Alps we have seen it, upon granite rocks, retaining all 

 the characters of the Scottish specimens. In size it exceeds all 

 the rest of the genus, and some individuals, with very falcate 

 leaves, might almost be taken for Jungermannia juniperina. 

 In its leaves it approaches the Andrcea last described ; but their 

 form is lanceolate, by no means subulate ; their texture thinner 

 and softer ; their colour paler ; those of the perichcetium do not 

 differ from the cauline leaves, whilst the very reverse is the 

 case with Andrcea Rothii, as may be seen both by the charac- 

 ters and in the figures.
