Tue genus Cladothele was first published in the Alga Antarctice 
of Hooker and Harvey in the London Journal of Botany, 1845, 
vol. iv. p. 293, and emgeegs the publication was repeated, 
th an illustration, i the Flora Antarctica, Pari. ii. p. 491,

tabs. 78 and 79), put a construction of his own on the enus, 
and figures C. Decaisnei and two other — C. ae (= Des- 
marestia filiformis J. Ag.) and C. Montagnei (= Nereia Montagnei 
Derb. et Sol.), with it. His figure of C. “Decaisnei i is plainly adapted 
from Flora Antarctica, and his opinion that it belonged to the 
Sporochnacea could hardly be maintained, though it will be seen 
later that his view is much nearer the mark than the original one. 
Harvey subsequently repudiated the Kitzingian view in his Index 
Generum Algarum, p. 2, where he quotes under Nereia as a synonym, 
“‘Cladothele Kg. (non H. f. & H.).” _He was, no ess right in
