8. Hecatonema Kjellmani Nordst., nov. nom. 
Sauvageau has examined an original specimen of 
Ectocarpus reptans Crouan, and found out (Sur quelques 
Myrionémacées, Ann. d. Sc. Nat., Sér. 3, Bot., T. 5, 1897, p. 
270), that it belonged to his new genus Chilionema, where 
he placed it as Ch. reptans. 
Kjellman had in »Bidrag till kännedomen om Skan- 
dinaviens Ectocarpeer och Tilopterideer , 1872, p. 52, t. 2 f. 
8, indentified and described a northern form as Ectocarpus 
reptans Crouan. 
Reinke regarded 1889, in his »Algenfiora der westli- 
chen Ostsee deutschen Antheils», p. 42 and Atlas deustcher 
Meeresalgen, p. 21, t. 19, Kjellmans form from 1872 as dif- 
ferent from that of Crouan and gave it the name Ect. 
repens. 
Kjellman in his Handbok i Skandinaviens Hafsalg- 
flora», 1, 1890, p. 81, put his species reptans Crn in the ge- 
nus Phycocoelis. When now this form of Kjellman ought 
to be brought into the genus Hecatonema, as H. Kylin 
thinks (Studien über die Algenflora der schwedischen West- 
küste, 1907, p. 41), then the species name reptans cannot be 
upheld, as Kylin would have it, because already Sauvageau, 
1. c., p. 273 had used the combination Hecatonema reptans, 
and as there is no real cause for its rejection. Now in- 
deed, Kylin has laid stress upon the fact that Kjellmans 
reptans was older than that of Reinke, but none of them 
had thought of using this species name as a new one, both 
quotifig Crouan as the original author. Even when Kjell- 
man 1890 brought the species in question into the genus 
Phycocoelis , he did not himself think of establishing a new 
species, as still he quotes Crouan as the original author.
