Rhodophyllis dichotoma f. setacea Kjellman. 



Unalaska, Alaska, Buprecht (1851, p. 593, under Ciliaria 

 fusca). 



From Ruprecht's description, it seems fairly certain that his 

 plant from Unalaska belongs under this form of Kjellman. 



Family SPHJSROCOCCACBAE. 



Gracilaria confervoides (L.) Greville. 



On rocks in the upper literal zone. Esquimalt, B. C, Harvey 

 (1862, p. 170); west coast of Whidbey Island, Wash., N.L.G., 

 No. 123!; Tracytou, Kitsap County, Wash , Widen, Nos. 215!, 

 216!, the latter under G. confervoides f. longissima. 



A common species of the coast of California, but apparently 

 not so common on the shores of Puget Sound. We cannot see 

 any difference between the two forms distributed by Miss Tilden. 

 Certainly what she indicates under f . longissima is the ordinary 

 form of the species and seems of equally common occurrence in 

 Europe. 



Corallopsis Salicornia (Agardh) Greville. 



Unalaska, Alaska, ('. A. Agardh (1820, pi. 8, under Hpluero- 

 coccus Salicornia) . 



It is generally admitted that Chamisso must have labelled the 

 type specimen of this species wrong. Ruprecht (1851, p. 318) 

 makes the statement that Chamisso, himself, was doubtful as to 

 whether he obtained the specimen at Unalaska or elsewhere. 



Hypnea musciformis (Wulfen) Lamouroux. 



C. A. Agardh (1821a, p. 326) gives this species a range in 

 the Pacific Ocean from Unalaska to New Zealand. Turner (1809, 

 p. 146) gives Nootka Sound, B. G, as the locality where Menzies 

 collected the plant he describes under the name of Fucus musci- 

 formis var. Wootkanus. These are the sources of all other refer- 

 ences to this plant as an inhabitant of our territory. We believe 

 that the reference to Unalaska may have been made by Agardh 

 under a mistaken geographical impression. Certainly Esper
