ington, thus giving this species, which has not been at all well 

 known to collectors and students of our Algae, a range from the 

 Santa Barbara Channel to Puget Sound. 



Fauchea Gardneri Setchell" mss. Frond flabellately expand- 

 ed, 6 to 15 cm. long, broad, flat, somewhat irregularly dicho- 

 tomously divided, parted and lobed, the ultimate lobes, for the 

 most part, broad, blunt, and little laciuiate, or entire, blood red 

 or very dark red, thickish and soft; composed of several layers 

 of large colorless cells in the middle layer, becoming smaller 

 toward the surfaces. Tetrasporic plants with finely corrugated 

 surfaces, due to the presence of the nemathecia or sori, which are 

 raised above the surface, and rounded and irregular in outline- 

 thickly placed together in no regular order, but giving the sur- 

 face a hieroglyphic sort of effect and occuring only on one surface 

 of the plant. Tetrasporangia 2 to 4 (tripartitely) parted, sur- 

 rounded by branched multicellular paraphyses which excrete an 

 abundant jelly. Cystocarps sparsely scattered over both surfaces 

 of the frond, prominent on one surface, hemispherical, without 

 coronal processes; carpostome small and inconspicuous, apical; 

 spore mass globular, not lobed, composed of compacted angular 

 spores, with a distinct placenta below imbedded in the loose and 

 regular network of filaments surrounding the spore cavity. 



Whidby Island, Washington, N. L. Gardner/, first collected in 

 the summer of 1898. To be distinguished from the preceding 

 species by the less lobed and not laciniate frond, the lack of a 

 corona on the cystocarp, and the different form and arrangement 



of the sori. 



Odonthalia dentata Lyngb. This northern species, credited to 

 the coast of California, but notmet with by more recent collectors, 

 has been sent to the writer from Trinidad, Humboldt County, by 

 Mr C M. Drake. It is abundant in the Puget Sound region. 



Bornetia secundiflora (J. Ag.) Thuret. Tetrasporic specimens 

 of this almost exclusively Mediterranean species were found 

 in small quantity, in March, 1897, growing onrocks near a beach, 

 in the vicinity of Pacific Grove, California, by Mrs. J. M. Weeks. 

 While the determination may not be absolutely certain in the 

 absence of cystocarpic specimens, yet the structure of the tetra-
