A larger and more robust moss tban D. pungens, nobis. wHcli it mnch resembles, differing in its longer leaves
which are more decidedly serrated, less convolute, nerve broader and excun-eiit, the perichætial ones much shorter’
and whoUy different m shape, capsule longer and strmnose, peristome larger. In general aspect it is not unUké
the Bntish B . majus. Turn., but is distinguished by the veiy long and attenuated leaves.

The var. 4 is a very elegant moss, differing in aspect from the other varieties, bnt we are unable to detect saffi-
cient characters to establish it as a species.

Our specimens agree precisely with an original one from P. de Beauvois himself. The leaves are more falcate
and wider at the base than those of D. Billardieri, to which this moss is very closely allied.

H a b . Falkland Islands, amongst stones on Mount Vernet, n o t common, and always barren.
Tliis peculiar condition of the moss is probably the result of its exposure to a dry atmosphere. Similar appearances
occur in such British species as Campylopusfiexuomoe.
