113 Vol. XLIII., Art. 1.— K. Ycndo : 



45 cia. in length, in dried state as thick as the middle fingei\ 

 cylindrical below and gradually terete above. The specimen in 

 the Phycotheca has the stipe cylindrical nearly to the transition 

 region, hardly 3 mm/'' in diameter, the sporophylls are linear- oblong, 

 with roundish bases and sharply defined, short petioles. In the 

 shape and texture of sporophyll the plant approached very much 

 A. marginata P. et R., but differed from it by having a distinctly 

 narrowed midrib and in the mode of sporophyll arrangement. 

 I wrote my questions on these points to Prof. Setchell and re- 

 quested him to spare me a typical specimen of A. valida. He 

 was kind enough to favour me with two well-prepared specimens. 

 They are quite similar to the specimen above remarked, hence 

 I have no more hesitation in mentioning the plant as a valid 

 and wx41- defined species. In his latest work " The Kelps of the 

 United State and Alaska," p. 163, Setchell mentions A. valida 

 in an independent specific position. 



The specimen distributed by Miss Tilden under Alaria curtipes 

 as American Algae, No. 521, in the copy I have seen, is to be 

 .identified with the present species. Setchell and Gardner^) com- 

 pared the description of A. curtipes Saunders with A. prœlonga 

 Kjellm. Her specimen, however, does not agree with the descrip- 

 tion, and its sporophylls show the characteristics of the Metasoria.
