Tur Moss-Flora of the Azores, the Canaries, and Madeira, so far 
as it is possible to judge from the small collection from the Azores 
given by Mr. H. C. Watson, the enumeration of those from the 
Canaries by Dr. Montagne in Webb and Berthelot's *Hist. des Iles 
Canaries, and the collections brought home year by year by Mr. 
J. Y. Johnson on his return from his winter residence in Madeira, 
would appear to be very nearly identical. Nearly all the species 
enumerated from the Canaries have already been detected in 
Madeira ; but, even when allowance is made for the position of the 
Flora as belonging to the Mediterranean region, there still remain 
a number of species attributed to that Flora which ought to occur 
in Madeira. Besides the presence of a few species so far as yet 
known peculiar to the Atlantic Islands, as Astrodontium Canariense 
and Neckera intermedia, Brid., their Flora contains some other 
species which, although hitherto known to occur in very few 
places in Europe, may be expected to be found on the south or 
western coasts of the British Islands. That this supposition is 
not unreasonable is proved by the finding of Myurium Hebri- 
darum, Schimp., a moss common to the Azores and Madeira, in the 
Hebrides. Amongst the specimens obtained by Mr. Johnson in 
Madeira are three remarkable species, supposed, in the accom- 
panying descriptions, to belong to the Leskeoid mosses ; of these
