THE LONG-TAILED SKUA. 
BuffoAs Skua (Yarrell). 
Lestris longicaudatus , Brisson (sp.) 1760. 
Stercorarius „ ,, 
Lestris Buffonii, Boie, Yarrell. 
Lestris parasiticus, 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 1832 exhibited a specimen from 
Orkney at a meeting of that society, as the first one that had 
been met with.t My note has been transferred by Mr. Yarrell to 
L. RicJiardsonii% — “the true 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. 
Richardsonii, and also, the name applied to it in the f Eauna 
Boreali- Americana/ where the two species were first distinguished.
