ie CRYPTOGAMIA ANTARCTICA. [Auckland and 
Var. y, major ; foliis majoribus latioribus luride viridibus, dentibus 8 geminatis. (Tas. LVII. Fig. IV. 6.) 
Has. Lord Auckland's group; vars. a and 8, in spongy bogs and in holes of trees in the woods, 
frequent. Campbell's Island; var. a, not uncommon; and var. 8, in the wet and wooded valleys, on the 
ground. > 
From its northern ally, S. mnioides, this species differs, both in the structure of the peristome and in the shorter 
calyptra, which is mitrzeform and inflexed at the base; also in the carinate leaves. The inflorescence appears truly 
monoicous, once only we found a hermaphrodite flower. In the varieties a and 8, the theca varies greatly in form, 
and the columella is either included or exserted. In var. y, the leaves are often very large, and the teeth connive 
so closely as to appear but 8, which are separable into 16 ; they are pale yellow, each with a faint middle line : when 
dry they are erect, recurved or reflexed, and generally of a purple brown colour.

5. DRYPTODON, Brid. 
Peristomium simplex. Dentes sedecim, insequaliter bifidi, v. apice lacero-fissi. Calyptra mitreeformis, basi

This genus is perhaps not distinct from Grimmia.

v. e basi ovata gradatim subulato-acuminatis carinatis nervo percurrente, seta perbrevi, theca elliptica, oper-

Has. Campbell's Island ; on alpine rocks. 
Caules laxe ceespitosi, superne fastigiatim ramosi, subrigidi. Folia erecto-patentia, subrecurva, margine basi 
reflexa, forma sat varia, superiora longiora, apice subdiaphana, vix pilifera, nervo valido continuo instructa, flavo- 
viridia, siccitate crispatula erecta; perichetialia breviora, elliptico-oblonga, obtusa v. acuta. Sefa vix lineam longa, : 
foliis immersa, pallida, tandem lateralis. Theca erecta v. inclinata, elliptico-oblonga, fusco-lutea. Peristomii dentes vix 
ad medium fissi, rufi, conniventes, siccitate reflexi. Operculum conico-rostratum, rectum, theca 2 brevius. Calyptra 
conico-mitreeformis, subplicata, costata, fusca, basi lacera et inflexa, operculo paulo longior. Annulus parvus. 
The foliage of this moss bears a considerable resemblance to that of Racomitrium fasciculare, from which it 
differs in the very short seta, pale elliptical theca, and in the peristome being truly that of a Dryptodon.

Haz. Campbell’s Island; amongst tufts of grass at the foot of precipices, rare and barren. 
This does not appear to differ from European specimens.
