Sterna sandvicensis. Latham's name, dating from 1787,*has 

 two years' priority over Gmelin's Sterna cantiaca, 

 1789. 



Sterna fuliginosa. As Gmelin's description is founded on 

 Buffon, the type-locality may be taken as Ascension 

 Island, whence the bird was brought to Buffon. 

 Linnaeus' S.fuscata (Syst. Nat. 12th ed.i. 1766, p. 228, 

 ex Brisson) is based on a young bird, and the identi- 

 fication with the Sooty Tern is uncertain. It is used 

 in the A. O. U. Check-List. 



Genus HYDROCHELIDOX. Type by subsequent designation 

 of Gray (List Gen. Bds. 2nd ed. 1841, p. 100): 

 H. nigra (Linn.). 



Hydrochelidon leucopareia. Owing to the discovery that 

 Pallas' Zoogr. Rosso-As., although dated on the title 

 page 1811, was not published till 1827, Temminck's 

 name, dating from 1820, has priority over Sterna 

 hylrida Pall. 



Genus CATHARACTA. Briinnich's name, dating from 1764, 

 antedates Megalestris Bp., 1864, founded for the same 

 bird. The Committee do not consider that Catarractes 

 Brisson, 1760, proposed for the Penguin C. clirysocotne 

 invalidates Briinnich's name, as they are spelled so 

 differently, though doubtless they have a similar 

 derivation. 



Catharacta skua. Briinnich's name for this bird dates from 

 1764 ; Linnaeus described Larus catarractes in the 12th 

 edition of the Syst. Nat. 1766. 



Genus STERCORARIUS. Type by tautonymy : S. stercorarius 

 Briss. =S. parasiticus (Linn.). 



Stercorarius parasiticus and S. longicandus. The correct 

 identification of Linnaeus' Larus parasiticus has long 

 been a source of controversy. His diagnosis in the 10th 

 edition of the Syst. Nat. might well refer to either
