ness of the nomenclature. Such a series of plants is of the greatest 
help to the student, serving him better than the most graphic descrip¬ 
tion or the best executed drawing. The following are the species 
represented:—1-3, Gharafragilis, Desv., type and two marked forms; 
4-6, C. fragifera, Durieu; 7, G. connivens , Braun; 8-9, G. aspera, Willd.; 
10-11, G. polyacantha, Brann ; 12-13, G. hispida, Linn. ; 14-17, G. vul¬ 
garis, Linn.; 18-19, G. canescens, Loisel ; 20, Lychnothamnus stelliger, 
Braun ; 21, Lamprothamnus alopecuroides, Braun ; 22, Tolypella intri- 
cata, Leonh. ; 23-24, Nitella tenuissima , Kuetz; 25, N. translucens, 
Agardh; 26-27, N. Jlexilis, Agardli; 28-29, N. opaca, Agardh; 30, 
N. capitata, Agardh. The work will be completed in three fasciculi, at 
one guinea each, and should form apart of the library of every natural 
history society in the kingdom. It may be obtained from Messrs.

The British Moss Flora. By R. Braithwaite, M.D., F.L.S. 
Part XIV., Fam. XV., Bryacese II. 6s. 
The unusual delay in the issue of this part has been caused by 
circumstances greatly to be regretted ; first, the serious illness of the 
author ; and, more lately, the death of his artist, whose beautiful 
reproductions of the author’s exquisite delineations have given so 
great a charm and value to the work. In this part the author 
continues his monograph of the British Bryaceae, with the fulness of 
description and beauty of illustration which have characterised the 
preceding portions of this work. The part contains forty pages of 
text, in which forty species and fourteen varieties are fully described, 
and is illustrated by six plates with beautiful delineations of thirty- 
three species, many of which are figured for tbe first time as British 
species. There are several needful alterations in nomenclature of both 
genera and species. The generic name Pohlia, first applied to one of 
the species of this group by Hedwig, 1787, replaces the name TVebera, 
generally used for the genus ; the name Webera was, however, 
preoccupied by Ehrhart in 1779. Descriptions are given of twelve 
species of Pohlia, three of which, P. cucullata, P. gracilis, and 
P. commutata are new to Britain. The rare little moss, better known to 
British botanists as Bryuvi Tozeri, or Webera Tozeri, is here named 
Epipterygium Tozeri. Schimper’s genus Zieria is replaced by 
Plagiobryum, Lindberg, Zieria having been previously adopted by 
Smith for a genus of Australian Rutaceae in 1798. This genus 
contains two characteristic species, P. Zierii and P. demissum. This is 
followed by Bryum. B. julaceum, of Bry. Brit., is now B. Jiliforme ; 
Bryum rufum, of Fergusson, is found to be the beautiul Norwegian 
species, B. purpurascens. Bryum fallax and B. rubens are new British 
species; Bryum atropurpureum, of Bry. Brit., takes the older name of 
Dickson, B. bicolor ; and B. apiculatum, of Bry. Brit., is B. Mildei, 
Juratz; Bryum bimum, var. cuspidatum , of Bry. Brit., is raised to 
specific rank as B. affine. From the foregoing sketch it will be seen 
that this is a most valuable portion of a truly great work, and all 
bryologists will sincerely hope that we may soon see the two parts 
XV. and XVI., which will complete Vol. II. J. E. Bagnall.
