198 Rhodora [NOVEMBER 
NOTES ON THE PRECEDING LIST. 
It will be seen that this Second Revised List includes 196 species, 
a gain of 19, or nearly 11 per cent. over the first Revised List. From 
Maine 151 species are now reported, a gain of nearly 23 per cent.; 
from New Hampshire, 154 species, a gain of about 18 per cent.; 
from Vermont, 137 species, a gain of nearly 26 per cent.; from Massa- 
chusetts, 121 species, a gain of nearly 25 per cent.; from Rhode 
Island, 82 species, a gain of about 6 per cent.; from Connecticut, 147 
species, a gain of nearly 10 per cent.; and from all six states, 67 species, 
a gain of about 28 per cent. The increases during the last ten years 
are naturally less striking than those between 1903 and 1913 (see 
Ruopora 15: 26). 
The list includes the following additions to local state floras, made 
during 1923: Riccardia latifrons for Rhode Island, the record being 
based on specimens collected by the writer at Westerly; Pellia 
Neesiana for Vermont, based on specimens collected by Miss Lorenz 
at Ripton; and Lejeunea patens for Connecticut, based on specimens 
collected by Miss Lorenz at Thomaston. The writer has likewise 
collected Riccardia multifida, Chiloscyphus pallescens, Harpanthus 
scutatus and Cephalozia curvifolia at Westerly, so that the Rhode 
Island records for these species are now given the + sign. 
If the Second Revised List is compared with the first a number of 
differences become apparent. Some of these represent additions and 
others changes in names, the latter being largely due to modifications 
in the interpretation of genera and species. For the sake of con- 
venience the differences between the lists are summarized below, 
with references to the Notes, the Roman numeral in each case in- 
dicating the number in the series and the Arabic numeral the page.
