Excerpt from Pycnogonida of the West Coast of North America The Pycnogonida collected by the Harriman Alaska Expedi tion form the basis of the material described in the following pages. They were obtained by those members of the party who devoted their attention to the invertebrate forms, Professor W. E. Ritter, Dr. W. R. Coe, and Professor Trevor Kincaid; I have also to thank Professor Kincaid for several specimens collected by him upon a previous trip to the Pribilof Islands, in 1897. In addition to the above, the Pycnogonida in the collection of the University of California, from various places along the California coast, were placed at my disposal. Finally several lots, also from California, were turned over to me by Dr. S. J. Holmes, to whom I am indebted for many courtesies. I have been generously permitted to include descriptions of all these forms, so that, with the exception of two previous notes, each describing a new species, of which one is included in the present collections, all that has been written on the littoral Pycnogonida of the west coast of North America will be found in this paper.
