reasons. Not only is it the nearest point to the Continent 

 and in the direct course of the migration of many species, 

 but 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, Haven, 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 Gargancy, 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. Ticchurst 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.
