2 28 TRANSACTIONS—PERTHSHIRE SOCIETY OF NATURAL SCIENCE. 
founded. I believe, however, that the rectification of all these errors, 
if that were possible, would not exclude more than one or two species 
from the list, although in some cases the number of stations might be 
reduced. 
I have enclosed within parentheses the name of the collector or 
recorder of those species Perthshire specimens of which I have 
neither seen nor collected. All the other species I have either 
gathered or seen, but not in all cases from every station here recorded. 
On some future occasion, when my information is more complete, 
I hope to give the distribution of each species with reference to the 
county divisions adopted by Dr. White, and, in the case of the rarer 
or more doubtful species, to indicate the authority for all the stations 
given. 
In preparing the list I have utilised, in addition to my own Her¬ 
barium, that of the late Dr. White, now in the Society’s Museum. 
I have also consulted the various Floras, Periodicals, and Transac¬ 
tions which are contained in the Museum Library, and am indebted 
for some information on the subject to botanical correspondents who 
have collected in the County. 
The nomenclature, and the generic and specific order followed, 
are those adopted in the “ Handbook Catalogue of British Mosses,” 
by H. N. Dixon.
