Similar specimens to tliose just described, but bearing only monosporangia, 

 were Found attached to Flustra foliacea near the Jutland Reef. To this variety may 

 also be referred some small specimens found nearly in the same place as the first 

 described, and on the same substratum (no. 7109). Their primary erect filaments 

 were up to 11 // thick but consisted of rather short cells, 1,5 — 5 diameters long, 

 and the fertile branchlets were placed more irregularly, often on the primary lila- 

 ments and occurred often in small quantity. As they otherwise agreed with the 

 just described f. cimbrica they must be regarded as poorly developed specimens 

 belonging to this variety.

Kylinia gen. nov. 



Plantse minutissima3, habitu et crescendi modo Chantransice. E cellula basali ger- 

 minatione sporae orta fila libera plus minus ramosa horizontaliter egrediuntur. Mono- 

 sporangia in fills terminalia vel lateralia. Antheridia singula vel bina, in cellulis 

 androphoricis erectis, multo angustioribus quam cellulis vegetativis, hyalinis, ter- 

 minalia. Carpogonia terminalia vel lateralia vel in cellula basali sita, post foecun- 

 dationem primo latitudine aucta et longitudinaliter divisa. Carpospora ut videtur 

 pauca oblonga vel leviter curvata, in una planitie subflabellatim disposita. 



1. Kylinia rosulata sp. nov. 



Cellula basalis hemisphserica fila plura, usque ad 7, horizontaliter emittens. 

 Fila simplicia vel plus minus ramosa, ramis plerumque oppositis horizontaliter 

 egredientibus. Cellulse 4,5 — 5,5 [i crassae, latitudine vulgo 1,5 — 2-plo longiores, rarius 

 ultra, chromatophorum parietale continentes. F'ila nonnunquam pilo hyalino te- 

 nuissimo terminata. Sporangia terminalia vel lateralia, ovata , 6,5 — 8,5/^ longa, 

 5 — 5,5 lata. Cellulse androphoricse 1 — 1,5 p. latse, c. 4 — 7 p. longse, ad apicem et 

 dorsum cellularum vegetativarum vel, ut videtur, carpogoniorum , singuhe rarius 

 binse. Antheridia 2 — 4// longa, 1,5 — 2,5 p. lata. Cystocarpia, ut videtur, paucicellu- 

 laria, carposporis c. 3. 



This curious little plan I has only been met with once in the Northern Kattegat 

 where it was found growing fairly abundantly on a specimen of Sporochmis pediin- 

 calatus. It occurred only on the assimilating filaments which form a tuft on the 

 fertile branches of this plant, and their number was often so great that these fila- 

 ments were rose-coloured in spite of the extreme smallness of the epiphyle. Its 

 appearance is that of a Chantransia of the group with one basal cell; it is indeed 

 somewhat similar to Chantransia hallandica ;-, parviila. The basal cell is hemi- 

 spherical, attached to the substratum by a thin layer of cementing substance (fig. 67£). 

 It gives oft" at all sides in a horizontal direction, but not from the upper side, a 

 number of filaments, in well developed plants (5 or 7. These filaments grow out 

 along the surface of the filament of Sporoclmus but are not attached to it; they
