_ Professor Schinidle adds :—‘‘ West has described in his Algee of Madagascar 
(Lin. Soc. of London, October, 1895) a C. pseudoregnesii, p. 59, Plate VI., figs. 42 
and 43, which I consider to be identical with our variety. already 
appeared in Hedwigia in April, 1895, my nomenclature has priority. Should the 
alga be included in the separate species it must therefore be called C. montanum.”
