As for the additions which have been made to 

 the literature relating to British Birds during the 

 period referred to, the steady progress which has 

 been made in the publication of County Avifaunas 

 has been most remarkable, and very few counties 

 now are without one or more ornithological re- 

 corders. 



It may serve a useful purpose to give here a list 

 of such books as have been published since 1872 

 on the birds of particular counties or portions of 

 counties, and larger areas within the British Islands, 

 if only to show the progress which has been made 

 in the exact study of British Ornithology, a fashion 

 which was inaugurated in 1866 when the publication 

 of the " Birds of Middlesex " and the first volume 

 of the " Birds of Norfolk " paved the way for an 

 investigation of the avifauna of other counties. Ar- 

 ranging them alphabetically, the following works 

 have appeared since the former edition of this 

 " Handbook " was published : — 



Argyll and the Inner Hebrides, Harvie- Brown 



and Buckley, 1892. 

 Bedb^ordshire, Steele Elliott, 1897-1901. In progress.
