He further adds (I. c. p. 34) : — " The general appearance of Larus audouini on the wing is 

 certainly more like that of Larus leucophceus than that of any other Gull with which I am 

 acquainted ; but the wings seem conspicuously longer, and of course at a short distance the 

 brilliant red bill is a clear distinction. The cry is not so harsh, and more prolonged than that 

 of the latter species." 



I have been unable to procure a specimen of this rare Gull for my own collection, and am 

 indebted to Lord Lilford for the loan of the adult male I have figured on the same Plate with 

 Larus gelastes. 



In the preparation of the above article I have examined the following specimens : —
