xii PKEFATORY NOTE. 



received most able and willing assistance from 

 numerous friends and correspondents either resi- 

 dent in, or closely connected with, the county of 

 Sutherland ; and they beg to express their thanks 

 to Mr. Houstoun of Kintradwell, Dr. Joass of 

 Golspie, Sheriff Mackenzie, and Mr. Hill of Helms- 

 dale, for many valuable communications respecting 

 the Fauna of the east and south-east districts ; to 

 Mr. Crawford of Tongue for lists and notes from 

 the north ; and to Mr. L. M'lver and Mr. Mur- 

 doch Kerr for Fish lists from Scourie and Loch 

 Inver. From the Messrs. Peach, and from Mr. 

 Mackay, Portnacon, they have received most ample 

 lists and notes on Fish of the north coast of the 

 county of Caithness and of the Moray Firth. 

 Mr. Mackay's notes were received too late, and 

 were too long to print in extenso, but they hope 

 to make a fuller use of these at a future date. 

 From the west they have received very valuable 

 assistance and practical aid from Mr. John 

 Sutherland, and Mr. John Munro of Inch- 

 nadamph, both being men well acquainted with 

 the birds of the district. Dr. Day — than whom 

 they could not have any better authority — has 

 most kindly looked over and revised their list
