RINGED GUILLEMOT. 459 



Spitzbergen, and the neighbouring seas. By M. Temminck 

 and the French naturalists the two birds are considered to 

 be distinct, and as such we have figured them." 



Examples of the Ringed Guillemot have been taken in 

 Lincolnshire, Yorkshire, and Durham, on the east coast, 

 and in Cornwall and Wales in the south. 



In the fourth part of his Manual, page 577, M. Tem- 

 minck says, "MM. Faber et Graba, qui ont sejourne en 

 Islande et a Feroe, assurent que le Guillemot bride et celui 

 ct gros bee ne sont que des varietes du Guillemot a ca- 

 puchon (Uria troile). Je suis tres-porte a admettre leur 

 opinion, basee sur des observations faites sur les lieux par 

 des juges competens. Toutefois, il se pourrait que ses 

 races voisines fussent melees et confondues exactement par 

 les memes causes et de la meme maniere que celles des 

 Corvus corax et leucopJioeus ; Comix et Corone ; Monedula 

 et Spermogulus ; Fringilla domestica et cisalpina" etc. 



In reference to the first part of this paragraph, it may 

 be stated, that since the true specific distinctions of Brun- 

 nich's Guillemot have been pointed out, namely, the form 

 and greater size of the anterior portion of the bill, and the 

 broad light-coloured stripe along the posterior half of the 

 margin of the upper mandible, no one that I am aware 

 of has considered it to be only a variety ; and if it is in- 

 tended that the claims of the Bridled Guillemot to be 

 ranked as a species, are equal to that of the Brunnichii, 

 then will both be entitled to be considered as species and 

 not as varieties. 



The meaning of the latter part of the paragraph is to me 

 also somewhat doubtful ; but that the Ringed Guillemot is 

 not a hybrid produced between the Common Guillemot and 

 the Brunnichii, seems proved by two circumstances ; first, 

 that the beak of the Ringed Guillemot is even rather more
