The Irish Naturalist. 
May 
slug with a tiled body and the common Roman snail, which is scarcely 
recognisable, are not in keeping with the other up-to-date figures. 
A new feature in the work is the praiseworthy attempt to acquaint the 
student with such genera as he might procure in the British Islands, 
by marking them British " (which we presume includes Irish). The 
author, however, does not seem to be thoroughly at home in the science 
of the geographical distribution of Mollusca, as he includes Zonites 
among the British genera, while the genus Hyalinia, or Vitrea, as it is 
often called, is not referred to at all. Moreover none of the following 
genera (all of which are British) are mentioned as such, viz., Amalia, 
Agriolimax, Punctum, Buliminus, Balea, Azeca, andTestacella. 
These are probably slight oversights scarcely detracting from the real 
merit of the book, which is full of interesting and reliable matter. The 
text throughout never betrays the fact that the manuscript was written 
in French, the credit of the excellent translation being due to Dr. 
Gilbert Bourne of Oxford.

THE BIRDS OF MAN. 
-The Birds of the isle of Wlan. By P. G. Rai.fe, M.B.O.U. Pp. 
Iv. + 321. Fifty illustrations, and two maps. Edinburgh : David 
Douglas, 1905. Price 185-. net. 
Mr. Ralfe has placed " Britannic " ornithologists under a debt of 
gratitude by the issue of the most excellent volume before us. An 
account of the birds of Man has been long required, and the expectations 
we had formed of the promised book have been realised on the whole. 
The introductory portion deals with a topographical description of the 
island, brief accounts of previous publications on Manx ornithology, and 
migration in Man, comparative notes on the birds, Manx bird-names, 
and a list of birds which are ascertained to have occurred in Man within 
the last century. Then follow 286 pages of detailed accounts of each 
species, and a bibliography, copies of local wild birds protection acts, 
addenda and index complete the volume. In the space of a brief notice 
it is not possible to exhaustively review the book, but some of the 
results of a careful study of it may be given. The volume treats of 183 
Manx species, roughly classified as follows :— Resident and breeding 75 ; 
Regular Summer Migrants breeding 18; Regular Autumn, Winter or 
vSpring Migrants not breeding 45; Occasional Visitants, 45. It will be 
seen how far these figures fall short of our Irish lists. Man agrees with 
Ireland, and differs from the opposite Kngli.sh counties^ in the absence 
or rarity of various summer migrants, such as the Blackcap, Garden 
Warbler, Wood Warbler, Redstart, Lesser Whitethroat; Yellow Wag- 
tail, and Tree Pipit; and of the Marsh Tit, of the Carrion Crow, of the 
Woodpeckers, of the Tawny Owl, and of the Jay. It also agrees with
