  1. Trevisan rejected Riella Mont, on account of Riella Raf.; Lév.; Orb. Dict. Univ. Hist. Nat. 8: 488. 1849. This, however, is a nomen nudum and is probably a misprint for Rimella Raf. Jour. Phys. 89: 106. 1819.
  2. Allusions to the occurrence of Riella Cossoniana in the Canaries have recently appeared in print (Bot. Tidsskrift, 24: 327. 1902; Rev. Bryol. 29: 110. 1902), but it is possible that these refer to Riella affinis, described below as new.
