 mscr., Polysiphonice, Hutchinsice, Ceramii, Rhodomela? sp. — 

 Frons erecta, partini e ratnis dorsiventraliter constructis lateraliter 

 ramosis sympodice crescens. Rami plus minus prolongati, teretes 

 aut leniter complanati, apice dorso incurvo insignes, e marginibus 

 lateris dorsualis plerumque alterne ramulos laterales duplici serie 

 emittenles. Celluke pericentrales saepius 4-8, rarius usque 18, diu 

 nu&se aut plus minus cito corticatae. Procarpia (sec. Falkenberg) 

 in ramis lateralihus sita. Antheridia in ramulis ultimis aut penul- 

 timis sita, subsessilia, foliaceo-complanata (an semper?). Tetraspo- 

 rangia in ramulis vix mutatis numerosa, acropeto modo mature- 

 scentia et tunc ramulum tumefacientia, nunc spiraliter nunc zig- 

 zag ad instar disposita, nunc quasi recto-seriata.

 a hasi articulatis decomposito-dichotoinis ramisque lateralibus den-

 recurvatis magis patentibus obsitis; articulis 4-siphoniis, primariis 

 diametro sesqui (usque 3-plo) longioribus; tetrasporangiis in ra-

Hab. in oceano Pacifico Peruviam alluente, ad « Callao » (Mon- 

 tagne) ; ad « S. Diego » Americse fcederatae (Collins). — Fila 

 (sec. Montagne) spithamaea aut minora, setacea, seusim in crassitiem 

 capillarem attenuata, a basi dichotoma axillis acutis ramisque late- 

 ralibus 4-6,5 min. longis corymbosis obsita. Rami dense decompo- 

 siti, dichotomo-ramulosi, superiores corymbosi fastigiati, adultiores 

 conformes at ob ramulos inferiores patentiores saepe recurvos di- 

 versum adspectum offerentes. Ramuli a basi latiore attenuati cras- 

 siusculi. Articuli primarii diametro sesqui-triplo longiores, in ra- 

 mis lateralibus sunt dianietro fere semibreviores, in ramulis plus 

 duplo breviores, siphonihus in his latioribus quam longioribus. Se- 

 ctione transversali conspiciuntur siphones 4 magni circa centra- 

 lem minorem, omnino ecorticati. Tetrasporangia in ramulis supre- 

 mis, inde tumidis, seriata, pauca i. e. 2-4. Color plantye recentis 

 roseo-purpureus.Substantia membranacea.
