The last variety much resembles R. aciculare, Dfil., but has acute leaves and the teeth of the peristome are
longer and more slender. It is perhaps stib more nearly albed to Trichostormm sulisecuudum. Hook, and Grev.,
(Hook. Ic. PI. 1 .17. f. 5), chiefly differing in its more robust habit and shorter setæ.

The last variety has some resemblance to A. heterostichum, var. y. gracUescem, (Bruch and Schimper), but differs
in having the leaves more acute and the teeth of the peristome larger and more regularly formed.

leaves more obscurely toothed than British examples, and the branches very short. I t may be U. Borbonieum,

It will be seen how closely the description corresponds with that of 0. coarctatum, Br. and Schimp.; but on
comparing authentic specimens, we find the leaves in the latter much wider and carinate, less dilated at the
base, more crisped when dry, the vaginula twice as long, capsule larger, and the habit considerably difierent.
Onr moss, unlike that, lias very little resemblance to 0. crispum, and is remarkable for its pale yellowish colour;
it varies in the length of the seta. An original specimen of 0. coarctatum (from P. de Beauvois in Professor Arnott’s
