Falklands, etc.] Hab. Kerguelen's Land ; on rocks near the sea, not uncommon.

Caules imciales, laxe casspitosi, ramosi, Folia suberecta, conferta, rigida, siccitate vix crispata, nervo lato crasao longe excurrente instructa, luteo-viridia ; perickaetialia longiora, basi latiora, erecta, convoluta. Seta 3-linearis, erecta vix tortilis, pallide rufa. Iheca suberecta, subrotunda, ore contracta, rufo-brunnea, demum atrorubens,vernicosa. Peristomii dentes 16, parvuli, conniventes, pyramidati, obtusiusculi, liuea media notati. Operculum conico-rostratum, capsular longitudine, rostro curvato acuto. Calyptra dimidiata, subventricosa, fusco-lutea. Floresceutia monoica.

We know of no described species with which this can be confounded. It is somewhat allied to the European W. acuta, but the capsules are larger, of a firm texture, retaining their shape when dry. In Dr. Lyall's specimens the leaves are more falcate and the seta shorter.

5. Weissia tortifoUa, Hook. fil. et Wils.; caule ramoso, foliis patentibus flexuosis siccitate crispatis lineari-subulatis canahculatis integerrimis nervo excurrente, perichsetialibus brevioribus convolutis, seta brevi, tbeca subrotunda, opereulo rostrato. (Tab. CLII. fig. V.)

Hab. Kerguelen's Land, common on gravelly banks, from the sea to 1,000 feet.

Caules subunciales, dense casspitosi, ramosi. Folia patentia, varie flexuosa, siccitate crispata vel tortuosa, nervo gracdi excurrente instructa, lutescenti-viridia, inferiora fuscescentia; perichastialia breviora, ovata, acuminata, convoluta. Seta vix 2-hnearis, crassiuscula, fusco-brunnea. Theca erecta, subrotunda, rufo-brunnea, verrucosa, demum indurata. Peristoma dentes 16, pyramidati, conniventes. Operculum conico-rostratum, eapsulae longitudine, rostro obliquo. Calyptra cucullata, capsulam sequans illamquc obtegens, brunnea. Floresceutia monoica.

Very closely allied to Weissia striata (nobis), but differing in the crisped widely spreading leaves, which are only half as long as in that species.
