reasons. Not only is it the nearest point to the Continent 
and in the direct course of the migration of many species, 
hut it is well known to receive constant visits from others 
which stray from their normal routes, while in several cases 
the first British specimens on record have been obtained 
within its limits. The Dartford Warbler, the Cream- 
coloured Courser, the Kentish Plover, and the Sandwich 
Tern are cases in point, and for these the author has given 
us reproductions of the original plates of Pennant, Latham, 
Lewin, and Boys respectively. 
Kent is so bountifully supplied by Nature with woods and 
marshes suitable for breeding-sites that a rich avifauna is the 
natural result, while its chalk cliffs and the vast expanse of 
shingle at Dungeness are a still further attraction to birds. 
The Bearded Tit, Baven, Chough, and Kite no longer nest 
within its boundaries, but the Blue-headed and Grey-headed 
Wagtails have been proved to do so, and the rarer Ducks, 
such as the Garganey, are perhaps increasing in numbers. 
The book itself, however, must be consulted for the long 
series of birds of all descriptions which the careful investi¬ 
gation of Dr. Ticehurst and his helpers have enabled them 
to include within its pages, and we strongly recommend all 
our readers to consult for themselves this accurate and well- 
written account of a most interesting county. 
Not the least important feature of the work is an ex¬ 
cellent Introduction, dealing with the physical features of 
the district, the bird-collections to be found there, and the 
migratory movements of the various species. The last- 
named subject is, moreover, repeatedly under discussion 
throughout the volume, and is evidently one of the chief 
objects with which it has been written. 
The- illustrations are good and well suited to the letter- 
press, while two maps of the county are given—one topo¬ 
graphical and the other geological. 
The classification used is based on that of Howard 
Saunders, but where Dr. Hartert has distinguished a 
British from a continental form, his views have been 
adopted.
