that we are now better able to study and compare Dr. Rusby’s 
specimens. 
In 1893 we received a. much larger collection of mosses than 
Dr. Rusby’s, made by Mr. Pierre Jay in northern Bolivia, also 
from the vicinity of La Paz and Sorata. I again wrote to M. Besch- 
erelle, offering to send him a complete set if he would name 
them. He replied that he was so occupied with his studies of the 
mosses of Japan that he found it impossible to undertake it and 
that it was a thankless task acting as secretary for some one else. 
I might, perhaps, have been strongly tempted to take the same 
stand had there not been twelve pages skipped in the reprints of 
Dr. Rusby’s enumeration and held in reserve for this list of 
mosses. Just as we are going to press I have received a pos¬ 
tal card from M. Emile Levier, inquiring for the Bang collection 
of Bolivian mosses and telling me that Dr. Carl Muller is printing 
in Florence a Bryologia Boliviano,\ As my manuscript is completed 
and the priority of Schimper’s names from Mandon’s collections is 
maintained throughout, we think it best to publish our enumera¬ 
tion independently. 
This summer I have also commenced wrapping and sorting 
Mr. Jay’s collections and have found several of Dr. Rusby’s new 
species in fruit, which had previously only been collected sterile, 
so that the work promises to be of great interest, but will take a 
good deal of time to accomplish with the limited collection at my 
disposal and the pressure of other duties. However, it seems best 
to publish the list of Dr. Rusby’s collection as it stands, first with 
such determinations and descriptions as I now know to be correct, 
and to modify and amend this list subsequently as I find time to 
study and compare the fine collections made by Mr. Jay. 
The sequence of genera followed is nearly that given by Mitten 
in his Musci Austro-Americani (Journ. Linn. Soc. 12: 12-25. 
1869). Thirty-nine genera and ninety-six species are enumerated 
in this collection of which forty-two are new or previously unde¬ 
scribed. Six mosses, as many hepatics, four lichens and a few 
algae and fungi were also collected in Bolivia by A. M. Bang and 
enumerated by Dr. Rusby (Mem. Torr. Bot. Club, 4: 273). 
These were named by Mr. Wright at Kew, but the Sphagnums have 
since been examined and corrected by Dr. Warnstorf from speci¬ 
mens preserved in the Boissier Herbarium at Geneva.
