U. TOMENTOSA nob. = BniPiLiA TOMENTOSA Kiitz. Antilles, Bonder ! 



U. ? LUTEOFUSCA nob. = FLABELLARIA LUTEOFUSCA Crn. Guade- 

 loupe, Maze 1 This very obscure form appears to me to be 

 an imperfect state of an Udotea. Agardh, who had not seen 

 a specimen (loc. cit. p. 76), says, "An potius Avrainvillea 

 forma ? " It is certainly not an Avrainvillea, though it 

 outwardly resembles one. 



[Agardh (loc. cit. p. 74) records Udotea Desfontainii Lam., from 

 Guadeloupe (Maze) on the ground of his placing Flabellaria 

 fimbriata Chauv. in Maze et Schramm Alg. Guad. p. 89, 

 under that species. But Mr. Boodle and I have founded our 

 Avrainvillea Mazei on No. 65 of their Algae which bears the 

 name of Flabellaria fimbriata. There has probably been a 

 mistake in distributing the specimens.]
