Gathering taxonomic data is fundamental to any biological or ecological research. It was the intent of this paper to increase the storehouse of taxonomic information by studying the marine algae of one section of the Oregon coastline. Netarts Bay was chosen because of its accessibility and generally primitive nature. It is in an area of Oregon largely untouched by phycologists and so offered an opportunity for original research. Techniques of collecting and preserving specimens were kept as simple as possible, thus allowing a proportionately greater amount of the available time to be spent in the classification of the organisms. The body of this paper is, therefore, an annotated list of the algae collected and identified. A total of 78 species were identified, the majority belonging to the division Rhodophta (45 of the 78). An effort was made in collecting to be as thorough as possible. Algae ranging in habitat all the way from the spray zone to the depths of Netarts Bay were included. However, while the collection is comprehensive, because of the great size of the Bay it is undoubtedly incomplete. Only further research can identify which algae have been overlooked or omitted. Photographs are in evidence throughout much of the text. It is hoped that they will illustrate some of the forms which might be found only in this region and also, as accurately as possible, to aid in the identification of species elsewhere.
