journey has prevented me from giving so many localities as I could 

 have wished, and from adding remarks on several of the new and 

 little-known species, which would have made it more vahiable and 

 interesting. The nomenchiture is chiefly that of the ' Bryologia Eu- 

 ropoea,' with the addition (when necessary) of the synonymes of 

 Smith's ' English Flora,' voh v. part 2, our latest authority on the 

 subject of British mosses. The species not included in Baines's 

 ' Yorkshire Flora' are marked with one asterisk, and those not de- 

 scribed in the 'English Flora' with two. The Hepaticae are not 

 inserted at all in Baines's ' Flora,' and no complete list of the York- 

 shire species has been previously published. The very few localities 

 which I have introduced, without having seen a specimen from them, 

 are included in inverted commas ; but they are on what I consider 

 unexceptionable authority. The Yorkshire mosses here enumerated 

 amount to 297 species, and the Hepaticae to 76. Perhaps no other 

 county can show numbers approaching to these, but it may be said 

 that this is sufl5ciently explained by its exceeding every other in 

 extent. However, more than half of it yet remains to be explored, 

 and Yorkshire Bryologists are " few and far between." Besides, in 

 tracts of country of very limited extent that have been well investi- 

 gated, as gi'eat a number of species has been found as anywhere in 

 England, within the same space. For instance, within a circle of one 

 mile from the High Force of the Tees, 40 species of Hepaticae have 

 been found ; and on Stockton Forest, near York, I have gathered, on 

 about an acre of ground, 29 species of the same tribe, all, with a 

 solitary exception, in fructification.
