related Scandinavian species detected by Harald Lindberg. A valuable 
hint as to staining of plants for demonstration of the pore-structure is 
appended, while the prefatory note that the author's drawings of non-Euro- 
pean mosses preparatory to his publication of the world’s species have 
reached the number of 3,940, is of general interest. The book is to be com- 
mended as well for its cheapness as its excellence to all interested in our own 
sadly neglected American sphagna. A. LeRoy Andrews.

BOOK NOTICES. 
Lichens of Mount Monadnock, New Hampshire, by Reginald Heber 
Howe, Junior. (Reprint from Am. Nat. 40 : 661-665. Sept. 1906.) 
This is an annotated list of seventy-one species and varieties collected 
by the author April 5th and 6th, 1906, upon the slopes and summit of Mount 
Monadnock (3166 feet) in Cheshire Co., N. H. The notes give the distribu- 
tion in the Transition, Sub-Canadian, and Canadian floral zones occurring 
on the mountain, the relative abundance of each species, and the substratum. 
Specimens of all species listed are in the author’s herbarium. 
Census Muscorum Australiensium. A classified Catalogue of the Frondose 
Mosses of Australia and Tasmania, collated from available Publications 
and Herbaria Records, by the Rev. W. Walter Watts and Thomas White- 
legge, F. R. M. S. In two parts. (Proc. Linn. Soc. N. S. W. 27 : Pt 3, 
Supp. pp. 1-90, and 30 : Pt. 4, Supp. pp. 91-163. Sidney, N. S. W. 
1902 and 1906.) 
These two pamphlets, which are issued under the auspices of the 
Linnean Society of New South Wales at the price of five shillings sixpence 
for the two, comprise in convenient form a list of the Australian acrocarpous 
mosses, including the Sphagnaceae and Andreaeaceae. The introduction 
reviews briefly the circumstances that led to the preparation of the list, and 
the work which has been done upon the moss-flora of this region by Mitten, 
Wilson, C. Mueller, Brotherus, and others. This is followed by an outline of 
the classificatory scheme used, which is, in the main, that of Dixon and 
Jameson’s “ Handbook of British Mosses.” Regarding the inclusion of cer- 
tain names the author says: “ It cannot, unfortunately, be claimed that 
there are no synonyms, nor nomma nuda , in this Census., The inaccessi- 
bility of specimens, and even, in some cases, of descriptions, the differing 
principles of determination adopted by specialists, and the large number of 
new species of which we know nothing except the names, make an unchal- 
lengeable list of Australian Mosses impracticable at the present stage.” 
In spite of these difficulties, nine hundred and eighteen mosses are listed, 
exclusive of varieties. No new species are described. The species and 
varieties are accompanied by notes, which are by no means bare records of 
places and collectors’ names. Much historical matter, discussions of the 
identity of doubtful species, frequent references to the original descriptions, 
with abundant synonomy, render these notes of great value to the student.
