676 Brixton: 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.
