by Harvey and Bailey in 1851 and the final enumeration 

 by the same authors (ef. Bailey and Harvey) appeared in 

 1862. Meanwhile more settlements had been made in the terri- 

 tory covered by this account, and odd collections had found their 

 way to various algologists. One of the most important was the 

 one made by Dr. David Lyall in the region of Esquimalt, B. C. 

 and in some other portions of Puget Sound, and sent to Pro- 

 fessor William Henry Harvey, at Dublin, who enumerated them 

 and described the new species in 1862. The most recent of ex- 

 ploring expeditions to visit any portion of the coast was that of 

 Xordenskiold in the Vega, which came down through Bering 

 Strait in 1880 and visited Port Clarence and St. Lawrence Island 

 within the limits of our territory. Professor P. R. Kjellman, the 

 botanist of the expedition, collected alga? at these localities and 

 later enumerated them in 1889, in his paper, Om Beringhaf- 

 vets Algflora. A short paper by one of us (cf. Setchell, 1899) 

 on the Alga? of the Pribilof Islands was one result of the efforts of 

 the Commission on Fur Seals and Pur Seal Islands to exploit the 

 fauna and flora of those islands and the alga? collected by the 

 Harriman Alaskan Expedition of the summer of 1899 were enu- 

 merated and described by DeAlton Saunders in 1901 . The Coral- 

 lines with jointed fronds of the region about Port Renfrew by K. 

 Yendo in 1902 and scattered references in the works of J. G. 

 Agardh and W. G. Farlow represent well all the remaining liter- 

 ature directly dealing with our territory. We have carefully 

 studied all of the literature mentioned above and have attempted 

 to incorporate the references to species and localities in the 

 following account, placing each under its proper species, as we 

 have recognized it, so far as we have been able to do so. 



COLLECTIONS. 



While the collections mentioned in the preceding paragraphs 

 have been for the most part inaccessible to us, a very consider- 

 able amount of material has been brought together from the 

 Northwest Coast, probably the largest collected together in any 

 one place and has formed the basis for the present enumeration.
