Dicrauella Schreheri, (3. robnsla, Sclipr. — D. leuta, Wilson, ms. — Re- seuibling a starved condition of D. sq/iarrosa, but in the leaf structure entirely according with D. Schi'eberi, with which for the present I retain it. Specimens with perfect fruit are given under n. 74 in Rabenhorst's ' Brvotheca,' the lid being shorter than in the typical form. Found at various places in Cheshire, at Milnthorpe by Mr. Barnes, and near Melrose with young fruit by Mr. Jerdon.

Ditrichum zonatnm (Brid.), Lorentz. — TFeissia zoiiata, Bridel, Brv. Univ. i. p. 364. — This is the correct synonymy of the plant described as D. tenne, ^. in Journ. Bot. 1870, p. 228, and for the present that species remains a desideratum in onr fiora. I may add that Mr. Fergusson sub- nutted specimens to the late Dr. Milde, Avho confirmed the correctness of the diagnosis ; the fruit is unknown.

D. Jlcxicanle, y. compaclam, Stirton. — D. Briimmondii, "VVils. nis. — In large tufts densely matted vvith purple radicles ; stems shorter, leaves shorter and thicker with denser areolation. Connected with the typical form by the var. /3. denimm, which Mr. Barnes sends from Helsington Barrows, Westmoreland. — Hab. Sides of rills on Ben Lawers (Dr. Stirlon, ISGG).


To this family I unite the J'Feisinceae, for the two groups approximate so closely in areolation, that it is not possible to draw any well-defined limit between them. We may, however, conveniently form three sub- families, Weisiece, Encaly piece, Trichodumea;.


Jnoiclninjbiyn, (pstivnm, (3. peU/icidnni, Wilson, ms. Leaves pale vel- lowish, scarcely at all crisped when dry. — Near Inverary, growing with the normal form.

JVeisia (§ Ilyiiienosti/litihi) coinmiitala, Mitten, Proc. Liim. Soc. vol. i. Snpp. p. 32 (Plate CXIX. f. 1). Dioicous, resembling ir.ctirvirost?-is. Leaves from a snb-ol)long base, lanceolate, narrowed, keeled with the nerve, which vanishes below apex, cells nearly all elongated and pellucid ; perichiftial leaves similar. Fniit like that of If. cxrvirofilris. Resembles the figure of (li/nnioalojinnii pallidiselum, Nees and Hsch. in Bry. Gerip., but as Mr. Mitten observes, it cannot be referred to any species whose leaf structure is not described. — Hab. Alpine rocks, Nant-y-Fydd, Wrex- ham (Mr. Bowman). For the specimen figured I am indcbled to my friend Mr. Da vies.
