JAMES _Dear Sir_--Along with this I send you the first installment of the papers, entitled "The Myxomycetes of the Miami Valley, Ohio." The work in these papers is based upon my ample collection of Myxomycetes growing in this region, comprising more than one hundred species; these have been diligently compared with specimens obtained from correspondents elsewhere in this country and in Europe.
