Sir W illiam J ard ine , Bart, and D r G revill e .—In England, it
has been found b y the late D r B runton near Rippon, and b y Mr H obs
o n near Manchester. In Ireland, by D r T aylor near Dublin. In all
these stations, I believe, the rocks on which it occurs are of sandstone.

divided. Leaves few, linear, erect, slightly flexuose, and somewhat
incrassated upwards, reticulated, dark olive-green. Perichætial
ones imbricated, more numerous than the cauline ones, mostly o f the
same colour, ovate, concave, the apex either obtuse, or somewhat acuminate,
reticulated, furnished at the base with an indistinct, short,
broadish nerve. Fruitstalk 3 or 4 lines in length. Capsule ovate, small,
reddish-brown. Peristome o f 4 broad, erect teeth, each of w hich is, u n der
a good microscope, obviously marked with 7 longitudinal striae. Lid
conical, shortly and obliquely acuminate. Calyplra linear-campanulate,
striato-sulcate, reddish-brown, sometimes with one or two lateral clefts.
