varieties. That same year Dr. Charles Willard Hayes, of the U. 
S. Geological Survey, collected a few lichens in Alaska, which 
were also submitted to me. 1 The list comprises 20 species and 
varieties. In the Report of the Fur Seal Investigation, 2 J. 
M. Macoun publishes a list of 70 species; he also publishes 
a list of 9 species collected by William Palmer and determined 
by W. J. Calkins. 3 In the summer of 1900 Mr. Arthur J. Col¬ 
lier, in connection with the work of the U. S. Geological Sur¬ 
vey, collected 10 species and varieties, which were submitted 
to me 4 for determination. Kurtz, in his Chilcat Flora, 5 men¬ 
tions two species, while Professor Farlow 6 records 4 from Point 
Barrow. Professor Tuckerman 7 gives various Alaska stations 
for different species, collected principally by Wright and Kel¬ 
logg. Wainio, in his recently published monograph on Cladonici, 8 
gives additional localities for species of this genus. Summing 
up, we find that before the publication of the present list 386 
species and varieties had been enumerated. The present list 
adds 76 species and varieties new to Alaska, making a total of 
462 species and varieties. 
The lichen flora of Alaska is essentially like that of other 
northern regions. Constant comparison has been made with 
the works of Fries, 9 Lindsay, 10 and Arnold, 11 for the distribu-
