C. subtilis, Woelius sp. This being 2 new species, Pro’ 
Moebius ae gives the following Latin description :—* Ch. thallo 
subtili e filis procumbentibus, thizoideis instructis et filis raris 
sporanguim mutata ; Soles etiam lateralibus prope peo vel 
prope trichomatum basim : 
Ch. thallus slender, re of creeping filaments We a 
furnished poet rhizoids and scanty upright filaments; a nt eu 
creeping filaments 10 p» t thick, saitivicted at the septa; cells 0 ca 
upright filaments 6-10 p» thie +k, rege branches 1n fe hang! , 
alternate or opposed ; the larcer few in number prolonge int af 
trichome; the small more Pr aueons with the terminal ¢ cell conve ea 
into a sporangium; sporangia also lateral placed near the ends or n 
the base of the trichomes. . eee 
These plants, which I can identify with ea ) e€

placed alternately or opposed in one plane; the longer re ie
