 autumn of 1849 along the coast of Norway. 



THE LONG-TAILED SKUA. 



BufFon's Skna (YarreU). 



Lestris longicaudatus, Brisson (sp.) 1760. 

 Stercorarhts „ „ 



Lestris Bu^onii, Boie_, Yarrell. 

 Lestris parasiiicus, Temm. (2nd edit.), Gould, Jenyns. 



Is of occasional occurrence in autumn on some parts of 



the coast. 



In a communication made to the Zoological Society of London 

 in 1834, it was remarked by me that " specimens of the true 

 Lestris parasiticus, Temm., have repeatedly occurred in the bays 

 of Belfast and Dublin.""^ I was induced to mention this cir- 

 cumstance from so very little being known of the bird as a 

 British species. Mr. Gould in 1833 exhibited a specimen from 

 Orkney at a meeting of that society, as the first one that had 

 been met with.f My note has been transferred by Mr. Yarrell to 

 L. RichardsoniiX — ''the tvne Lest, parasiticus, Temm.," which I 

 termed it, was intended to particularize the species now under 

 consideration, as that was the name used by Mr. Gould when 

 calling the attention of the society to it as distinct from L. 

 Eic/iardsonii, and also, the name applied to it in the 'Fauna 

 Boreali- Americana,' where the two species were first distinguished.
