to keep this sjoecies distinct fi-om L. pinnatijlda, with which it was 

 united by Harvey. 



Erythrocystis Grevillei J, Ag. Epicr. = Lomentaria'? saccata 

 J. Ag. Sp. p. 738. 



Delesseria Woodii J. Ag. Santa Barbara, Cal., Miss Lenne- 

 backer. 



NiTOPHYLLUM viOLACEUM, J. Ag. Epicr. This is the species de- 

 scribed in the Ner. Am. Bor. and Proc. Am. Acad., 1875, as Nitcphyl- 

 lum laceratum Grev. 



NiTOPHYLLDM LATissiMUM Harv. Under this species should be 

 included Nit. areolatum Eaton mscr. of the Rep. U. S. Fish Comm., 

 1875. 



NiTOPHYLLUM MULTiLOBUJi J. Ag. Epicr. Golden Gate, Cal., 

 Berggren. We have never seen this species, which, according to Prof. 

 Agardh, differs from all other species in having large transverse sori. 



NiTOPHYLLUM SPECTABiLE Eaton. California. 



EuCHEUMA ACANTHOCLADUM J. Ag. Epicr. ^= Chry^ymenia acan- 

 thocJada Harv. 



Rhabdonia ramosissima J. Ag. Epicr. == Chrysymenia ramosis- 

 sima Harv., Ner. Am. Bor. 



The species of CoralUnece found on the coast of the United States 

 are in a state of great confusion, and it will probably be some time 

 before they are clearly made out. One great difficulty in the way is 

 the uncertain characters by which the genera are at present constituted. 

 In this connection, we only wish to call attention to the forms found 

 on our coast, giving the names under which they are commonly de- 

 scribed, without meaning to indorse the specific value assigned by dif- 

 ferent writers. We are greatly indebted to Dr. Ed. Bornet for notes 

 and suggestions with regard to our species, especially the Gorallineae 

 and Sqnumarice. 



CoRALLiNA PiSTiLLAETS Mont. A small Coralline, nearly related 

 to this species, perhaps identical with it, has been found at Santa Cruz, 

 Cal., by Dr. Anderson. 



Amphiroa Orbigniana Harv. The common Amphiroa from 

 California, which is usually distributed as Amphiroa Californica, 

 D.cue., does not, according to Dr. Bornet, conform to the type of 

 that species, but more properly belongs to Ainpk. Orbigniana. Harv. 

 The species is incorrectly referred in Proe. Am. Acad., 1875, p. 364, 

 to Arthrocardia frondescens, Aresch., to wliich some of the broader 

 forms have a not very remote resemblance.
