Cli. forfKosa to his own Ch. liforea and this is as far as any 

 information concfrnin^- tlic ])lant fi-oni Sitka is known to ns. 



Chaetomorpha tortuosa (I)illwyn) Knetzing. 



"Parasitic" on Ch. iii<'la(j<nihiiii . Unalaska, Alaska, RnpyccJil 

 (1851, y). 397, nnder Conferva confcrcicola) . 



Harvey (18.')7, \). 88) says that he has received a specimen of 

 the Conferva confervicola Rnprecht from Rnprecht himself and 

 cannot distingnish it from the ijrescnt species. It seems, also, 

 that the Conferva Liinnn of Postels and Rnprecht (1840, p. 22) 

 may belong with it, since they mention that the specimens 

 referred to that species and collected at Sitka, are only half as 

 thick as European specimens of Ch. JJinini (Mueller) Kuetzing 

 Another possibility seems likely to ns, and that is that the speci- 

 mens quoted here maj- also be identical with what Mr. Collins 

 and Kjellman have referred, of North Pacific forms, to Ch. can- 

 II ah ill a. mentioned above.
