Genus COCCYZUS. Type by monotypy: " Coucou de la 

 Caroline" of Brisson = C. americanus (Linn.). 



Genus MICROPUS. Three generic names have been used at 

 various times for the Swifts. Apits Scopoli (Introd. 

 Hist. Nat. 1777, p. 483) is preoccupied by Apos, intro- 

 duced by the same author on p. 404 for a genus of 

 Crustaceans. As these names are identical except for the 

 interchange of " o " and " u," the earlier one only is valid. 

 The second is Micropiis Meyer & Wolf (Taschenb. 

 Deutscli. Vog. i. 1810, p. 280). This has been rejected 

 by Sharpe (Hand-List, ii. 1900, p. 95), as the same 

 name vfas applied to a genus of plants by Linna3us, but 

 under the present rules this no longer renders a name 

 invalid for zoology, and Micropus should therefore be 

 used. The third name, Cypselus Hliger, 1811, was 

 used in the 1st edition of the List and by most of the 

 earlier authors. The type of Apus is Apus apus by 

 monotypy, the type of Micropus is M. murarius Scop.= 

 Hirundo apus Linn, by original designation. The type 

 of Cypselus is C. apus Linn., by subsequent designation 

 of Gray (List Gen. Bds. 1st ed. 1840, p. 8). 



Genus CH^TURA. Tyj)e by subsequent designation of 

 Baird (Pacific E. R. Reports, ix. 1858, p. 144) : 

 C. pielagica (Linn.). This genus, proposed by Stephens 

 in February or March 1826, antedates Acanthyllis of 

 Boie (Isis, Oct. 1826, p. 971), used in the former 

 edition of the List and by Saunders. 



Genus CAPRIMTJLGUS. Type by Linnean tautonymy, 

 and by subsequent designation of Gray (List Gen. Bds. 

 1840, p. 7) : C. europceus, Linn. 



Caprimulgus ruficoUis. Hartert (Hand-list of British 

 Birds, 1912, p. 97, footnote) states that the example 

 killed near Newcastle in October 1852, the only one 

 known to have been obtained in the British Islands, 

 is referable to the desert form of this species, C. r.
