INTRODUCTION. 
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.
