Of the species mentioned by Rosenvinge I think it comes nearest to Acrodiætiiim (Chantransia) Pohjidis Rosenv. This species has only been found once at the south coast of St. Croix. 22. Acrochætium ernothrix nov. spec. Thallus cæspitulosus, ca. 400// altus. Pars basalis non certo observata est. Fila erecta a basi ramosa. Rami principales stricti, in inferiori parte paucis, in superiori numerosis ramis et ramulis instructi. Cellulæ ramorum 5—6// latæ et 15—18/« longæ, cylindricæ, chromatophorum zonatum prolongationibus irregularibus instruc- tum et pyrenoide centrali munitum continentes. Ramuli sporangiferi e 2—3, rarius pluribus cellulis compo- siti, ad apicem versus angustati in pseudopila longa producti. Monosporangia sessilia aut pedicellata, lateralia 2—3 seriatim posita, rarius terminalia, ovato-oblonga, 8—10// longa et b—Q(i lata. Of this characteristic species I have only succeeded in finding a single specimen.
