IQI3- The Clan Island Survey — Bolany. 53 
Mr. West's report on the Fresh -water Algae (to which 
Marine Diatoms are added) represents a vast amount- of 
work, and adds over 150 species to the Irish flora in this 
group, the knowledge of which in this country is largely 
due to his own work and that of his son. Professor G. S. 
West. The reports on the Musci, Hepaticae, and Lichens 
all add materially to our knowledge of these groups in 
Ireland, especially as regards the west coast. The addition 
of seven Hepaticae to the Irish list is a notable achievement, 
when we remember how thoroughly this class, like the 
Mosses, has been worked in Ireland. 
The high total of the flora of the district, and the fact 
that I 585 species are added to the Irish list, of which 
55 are now for the first time recorded from the British Isles, 
and of which 11 (and a number of varieties in addition) 
are new to science, shows the remarkable effect of intensive 
study of a defined area, even when, as in the present case, 
that area is not particularly favourably situated as regards 
climatic or edaphic conditions. 
The six reports together form, as shown above, a volume 
of 410 pages and 20 plates. ^ The plates are concerned 
mainly with the illustration of new or rare species, and of 
types of vegetation.

BRITISH AND IRISH BIRDS. 
The British Bird-Book. Edited by F. B. Kirkman, B.A., Oxon. Parts 
ix. and x. London and Edinburgh : T. C. and E. C. Jack. 
The British-Bird Book continues with each succeeding part to justify 
the claim of its preface that it would aim at bringing together " from 
every source, foreign and native, all the available information of any 
importance concerning the habits of British Birds." The accounts given 
in Part ix. of the SanderHng and Ruff, and in Part x. of the Golden Eagle, 
have only to be read to convince the most sceptical* that there' was a 
genuine need for a new ornithological work making this its principal 
object. None of these three chapters — contributed respectively'-by Messrs.
