Chubb (The birds of British Guiana, 1916, 1, addenda) gives 

 Griffith & Pidgeon Cuvier's Animal kingdom. Aves, 1S29, 1, p. 75, 

 as authority for Tyto iuidara (= Sirix perlata of authors). On look- 

 ing up the reference we find that the additional species were inserted 

 by John Edward Gray (Cf. lac. cit., p. 86, footnote). We change the 

 authority accordingly.
