Hab. Hermite Island, Cape Horn, Dr. J. D. Hooker. 
Very near to U. fulvella in habit, size, and in the torsion of its leaves ; 
but the base of its leaves with many series of pellucid marginal cells, 
the margin towards the apex irregularly erose, and the calyptra with few 
appressed hairs.

Hab. Terra del Fuego, Mr. Darwin. 
Resembles very closely U. Fuegiana, but with larger leaves, which 
have their cells more closely placed, and the vaginula pilose. 
U. LuTEA (Mitten). Monoica, dense pulvinata, fulvo-lutea, foliis sicci- 
tate crispatis madore patentibus e basi obovata concava erectiuscula 
lineari-lanceolatis nervo flavo sub apice evanido carinatis cellulis

10-12 inter marginem et nervum in folii medio dispositis papillosis

theca in pedunculo vix duplo longiore ovali cylindrica plicata collo 
elongato crassiusculo, operculo convexo brevi-rostrato, peristomio

Hab. Tasmania, on trees, rivulet behind Cumming's Head, Western 
Mountains, Mr. Archer; Mount Wellington, and in New Zealand, 
Wairoa River, Kaipara, Mossman. 
Corresponding in size with U. crispa, but wit 
form at the base, erose margins, and cells in the upper portion larger 
and further apart ; the capsule is also thinner.
