Alston) Due to war conditions, the author was unable to revise the edited manuscript of this paper. Bishop Museum is printing it in the best form possible under the circumstances, rather than withhold publication indefinitely.-Editor. INTRODUCTION In 1930, I was asked by Dr. Erling Christophersen (Bernice P. Bishop Museum Fellow, 1929-1930) to work out the collection of pteridophytes made by him in Samoa in 1929. All of his material, together with that collected by Bryan, Eames, and Garber, was sent to me by him. In 1931, Dr. Christopher- sen went again to Samoa, and the following year I received duplicates of all pteridophytes, except Selaginella, collected by him. This paper is based chiefly upon these collections and is prepared at the request of the Director of Bernice P. Bishop Museum. Unfortunately, other urgent work interrupted the study of these ferns, delaying its completion until the end of 1938. I first planned to write a paper similar to E. B. Copeland's "Ferns of Fiji" and "Pteridophytes of the Society Islands," but I soon found that plan unsatisfactory. Copeland based his two papers chiefly (that on the Society Islands exclusively) on collections worked out by himself, omitting all earlier reports, and his lists of species are therefore rather incomplete. I wished to prepare a complete, revised list of all known Samoan species based, if possible, on an examination of all Samoan collections, particularly types.
