248 THE ZOOLOGIST. 



The system on which I have worked may require a few words 

 of explanation. The titles of the works catalogued are arranged 

 chronologically under counties, the latter being divided under 

 England, Scotland, Wales and Ireland. The details' are entered 

 in the following order : — Surname of author, Christian name (in 

 parentheses) , as much of the title as is necessary for identification, 

 the name of the magazine or volume in which the article or list in 

 question appeared (if not separately published), place of publi- 

 cation, shape, and date, followed in many cases by a few brief 

 remarks on the work catalogued. The date of publication has, 

 contrary to custom, been placed after the size and shape, for 

 convenience of reference. In the case of magazine articles or of 

 lists which form portions only of larger works, the title of the 

 magazine or work of which they form part has been given in 

 italics, for the sake of distinction. 



The catalogue will, of course, indicate at a glance those 

 counties whose avi-fauna has received most attention ; but it may 

 be as well to point out those which have received least, and 

 which, therefore, chiefly require that some local observer 

 should undertake the work of setting forth the main peculiari- 

 ties of their avi-fauna. Taking England first, the list shows that 

 not a single contribution has yet (so far as I know) appeared in 

 relation to the counties of Monmouth or Warwick, which 

 are, therefore, obviously in want of some attention from 

 local ornithologists. The following counties, though they have 

 not altogether escaped attention, have had their ornithological 

 features most inadequately treated : — Bedfordshire, Cheshire, 

 Derbyshire, Huntingdonshire, and Surrey; while Hampshire, 

 Hertfordshire, Lincolnshire, Staffordshire, and Westmoreland, 

 without being quite so badly off, still stand in need of more 

 attention than they have yet received. Turning to Scotland, 

 one may note that the birds of many districts have been very 

 carefully studied by several different observers, while Gray's 

 Birds of the West of Scotland, the works of Messrs. Harvie 

 Brown, Buckley, and of some others, are models of their kind. 

 Nevertheless, there are comparatively few Scotch counties which 

 have received the attention in the way of separate and often 

 bulky works on their birds which many English counties havo 

 received, and a good deal of local work still remains to be done. 

 The twelve Welsh counties have scarcely received any attention 

 at all, only two having been anything like adequately treated,
