676 Britton: West INDIAN MOSSES 
According to Dr. Andrews’ notes ‘‘the Swartz specimens, which 
are deposited in the collections of the Naturhistoriska Riks- 
museum at Stockholm, are distributed through the herbarium of 
non-Scandinavian mosses, which are, in general, arranged after 
Paris’s Index. Packets are generally uniform, one to many on 
the herbarium sheet. Swartz’ specimens are recognizable by labels 
in his handwriting included in the packet, by the kind of paper 
with water-mark to which he pasted them and references of others 
to the origin of specimens.” 
We have seen specimens of all but two of these species, and 
have duplicates of many of them; it is therefore our intention to 
distribute sets of these and other West Indian mosses, in exchange 
for other exsiccatae and duplicates from the West Indies, Central 
America, and South America.
