A SUPPLEMENTARY LIST OF NORFOLK MOSSES, 
LIVERWORTS AND MYCETOZOA. 
By W. H. Burrell, F.L.S. 
Read 2()th March, 1910. 
A close examination of so large an area, makes the study 
of the distribution within the county of these Cryptogams 
a work of time ; and it seems desirable in the meanwhile, to 
place on record the plants which have recently been detected. 
In a few cases notes have been added on species previously 
recorded, where the record appears to need strengthening. 
The object of the paper is to bring the previous lists up to 
date, and show what members of these groups are known 
to occur in East and West Norfolk, No. 27 and 28 of
