532 BLACK TOED GULL. Class IL 



voke among the eggs and fea fowl of St. Kilda ; it 

 is there called Tuliac: his defcription fuits that of 

 the herring Gulh but we fufpecl: he confounds thefe 

 two kinds, and has transferred the manners of 

 this fpecies to the latter. 



Linnmis involves two fpecies in the article Larus 

 Cataratla ; this, and the arffic bird of Mr. Ed- 

 wards, birds of very different characters. M. Brif- 

 fo?i does not feem perfectly acquainted with this 

 bird ; for the fynonym of the Skua, given by him 

 to his fifth gull (our brown and white gull) be- 

 longs to this fpecies ; and his print of the Stereo- 

 raireraye, p. 152./^ 13. torn. VI. to which he 

 has given the fynonym of Mr. Edwards's ar&ic 

 bird, feems to be the very fame which we have 

 here defcribed.
