Calyptra conico-mitræformis, basì appendiculata, demiun lacera, pallida, apice flaveseens.
Our specimens, though uot in the best state for the examination of the capsules, all possess apparently a peristome
of eight teeth ; nevertheless we do not oonsider it necessary to remove this moss from Splachnum. Bridel’s genus
Fremodon is not adopted by Bruch and Schimper, and is indeed untenable. Our moss has characters ivhich induce
us to doubt whether it should be referred to Tayloria or to Splachnum of Brach and Scliimper. Its affinity with
the Em-opean Tayloria serrata aud Budolpliana is too striking to be overlooked ; bnt the pale apophysis, though not
wider than the capsule, is evidently that of a trae Splachnum ; while the peristome connects it with Bissodon, Br.
and Sell.

Allied to Grimmia apocarpa, var. rivularis, but very distmct in its falcate leaves, and broad thick nerve. As in
that species, the columella generally falls away -witli the operculum. The short fertile branches are often clustered
two or three together.
