Apparently a distinct species, somewhat allied to G. apocarpa, as to the fruit ; but in the foliage, more nearly to G. trichopliylla.

2. Grimmia falcata, Hook. fil. et Wils.; caulibus laxe csespitosis pendulis, foliis falcato-secimdis lanceolato-subulatis crassinerviis canaliculars integerrinhs, theca immersa subsessili turbinata, operculo rostellato. (Tab. CLI. fig. VIII.)
Hab. Kerguelen's Land ; on rocks and stones near a small waterfall. Caules laxe caespitosi, 1-3-unciales, penduli, flexuosi, ramosi, rami subincurvi. Folia imbricata, falcato-secunda, lanceolato-subulata, carnosa, integerrima, canalicidata, lateribus inflexis, nervo lato crasso excurrente, lurido-viridia, inferiora sfepe aqua destructa, nervo solo residuo, areolis minutis subquadratis. Pericheetialia ovato-lanceolata, acuminata, thecam superantia. Vagiuula conica. Theca subsessilis, subrotunda, ore patulo, brunnea. Amiulus nullus ? Peristoma denies magni, apice subperforati, iucurvi, dorso trabeculati, rubri, siccitate recurvi. Operculum heimspha?iicum, rostellatum, capsula brevius. Calyptra fusca, mitrasformis, brevis. Flos masculus in axillis ramulorum ad basin ramuli fructiferi. Antheridia plurima, eparaphysata. Allied to Grimmia apocarpa, var. rivularis, but very distinct in its falcate leaves, and broad thick nerve. As in that species, the columella generally falls away with the operculum. The short fertile branches are often clustered two or three together.

Hab. Herniitc Island, Cape Horn ; on granite rocks near the sea at St. Joachim's Bay.
Ab exemplis Britannicis his notis differt : caulibus longioribus pluries ramosis ; foliis magis patulis, subrecurvis, perichajtialibus apice diaphanis, nervo angustiore ; capsula majore.
This moss aifects the same localities in the Antarctic regions that it does in England. 4. Grimmia apocarpa, Linn.; Hediv.Musc. Frond, vol. i. p. 104. t. 39. Hoolc. et Tayl. Muse. Brit. p. 65. t. xiii. Scbistidium apocarpum, Bruch et Scliimper, I. c. p. 7.
Var. 1, foliis subpiliferis suberectis.
Var. 2, foliis obtusiusculis subpatentibus, perichsetialibus obtusis.
Var. 3, foliis caulinis angustioribus, perichsetialibus prsegrandis obtusis.
Var. 4, foliis lineari-lanceolatis longioribus.
Hab. Falkland Islands ; var. 1, slate rocks near the sea. Var. 2 and 3, Kerguelen's Land, on rocks, alt. 500 feet. Hermite Island, Cape Horn; on trap rocks near the sea.
The most striking feature of the three last named varieties is the large obtuse perichstial leaves. The habit and place of growth are similar to what this moss inhabits in Britain.
8. DEYPTODON, Brid.
This Bridelian genus appears to have been properly reduced to a section of Racomitrkm, m the 'Bryologia Europa?a' of Bruch and Sehimper.
