150 ANNALS OF SCOTTISH NATURAL HISTORY 



especially in the marshy hollows where the chicks were 

 accustomed to feed. This material, carefully examined, 

 served its purpose, and it has been thought desirable to 

 publish the list of species separately, inasmuch as it may 

 have a certain amount of interest from a purely faunistic 

 point of view. The Chairman of the Committee, Lord 

 Lovat, has very kindly sanctioned the publication of the 

 "List" in this Journal, and in order to retain its full bear-

 such species as have been picked up by the chicks in their 

 search for nourishment. Such species (as well as the 

 families to which they belong) are indicated in the list by 

 an asterisk.

 Banffshire ; and Burley-in-Wharfedale in Yorkshire.
