n. 
Tiie following Genus Campylosteliuni (8) was omitted because I hart no specimen in my possession, and could not obtain 
one at the time. I have, however, now received a Sussex specimen through the kindness of Mr. Mitten, and I gladly 
add it to the series of drawings. 
8. GENUS CAMPYLOSTELIUM, Br. ^ Sch. 
Whole Plant — Bi-triennial, small, slender, gregarious plants, growing in tufts on sandstone and granite rocks, closely 
allied to Selegerice in general appearance. 
Stem — Scarcely any, simple, very short. 
Leaves — Crowded, linear-subulate, narrow, entire, nerve strong, reaching nearly to, or quite to the apex ; areolae small, 
dot-like, basal cells larger and colourless. 
Inflgeescence — Monoicous. 
Barren Flower (Antheridia) — Gemmiform. 
Fertile Floiver (Archegonia) — 
Vaginula — Cylindrical. 
Capsule — Erect, ovate-oblong, or somewhat pyriform. glossy, pale red, on a geniculated fruit stalk. 
Calyptra — Mitriform, cleft at the base. 
Operculum — Conical at the base, with a long beak. 
Peristome — Single, composed of 16 lanceolate, trabeculated red teeth, entire at the base, upper portion divided. 
Annulus — Double. 
Spores — Very small, pale yellow. 
General Habitat — Growing on loose sandstone rocks in Sussex, Cheshire, and Yorkshire. Fruit : — " November." 
Species Illustrated — Campylostelium saxicola (Br. and Sch.), Grimmia saxicola. (Hook, and Tayl.)

III. 
The fruit of the two following genera being very rarely met with, the drawings given before were made from a plant which 
I was not allowed to dissect. 
Mr. Mitten, of Hurstpierpoint, has, however, recently, kindly given me specimens of fruit for my own use — Bicranodontium 
gathered on the Pyrenees, Qylindrotliecitmi {Entodon rubicii-ndus, Muller), on N.W. Himalaya; and Dr. Braithwaite 
has presented me with Entodon cladorhizans, gathered at Meran, in the Tyrol, by Dr. Milde. I therefore add dissections 
of these.
