In the study of certain critical families and genera the 
writers have received much assistance from Mrs, Elizabeth G. 
Britton, of the New York Botanical Garden, Mr. C. Warnstorf, 
of Berlin, Germany, and Mr. J. Cardot, of Charleville, France. 
Other correspondents, who will be mentioned particularly in 
the catalogue of species, have kindly furnished material of 
Connecticut Bryophytes for examination, and have thereby 
made the report much more complete than it would otherwise 
have been. To all of these the writers would express their 
sincere thanks.
