Sir, —I regret to say that an error has crept into Dr. Hart- 
laulPs account of Phleocis layardi described by him ( antea , p. 139). 
Its habitat is not “ Natal,” but the George District of the Cape 
Colony, where it was procured by my friends Messrs. W. and T. 
Atmore. 
I am Sir, &c., 
E. L. Layard. 
Professor S. F. Baird has been good enough to forward to us 
the following communication :— 
“ Messrs. Philippi and Landbeck have published descriptions 
of a considerable number of new species of birds of Chile and 
Peru in Wiegmann's ‘ Archiv fur Naturgeschichte/ as is doubt¬ 
less well known to most readers of ‘The Ibis/ It may not, 
however, be so well understood that nearly all these descriptions 
had previously appeared in the ‘Anales de la Universidad de 
Chile/ Santiago, and that consequently the dates given in the 
‘ Archiv 3 do not represent strictly those of the first introduction 
of the species to notice. The principal papers of these authors 
which are embraced in the series of ‘ Anales 3 thus far received 
by the Smithsonian Institution are as follows:— 
“ ‘ Descripcion de una nueva especie de pajaros del jenero 
Thalassidroma 3 Anales, xviii. Jan. 1861, p. 27. ( T . segethi.) 
“ ‘ Descripcion de una nueva especie de pajaros del jenero 
Caprimulgus 3 Anales, xviii. Jan. 1861, p. 29. [C. andinus.) 
‘“Descripcion de algunas especies nuevas de pajaros/ Anales, 
xviii. June 1861, p. 731. ( Upucerthia albiventris , Larus fro - 
heeni, L. cinereocaudatus .) 
“‘Sobre los especies cbilenos del jenero Tulica 3 ( Fulica ), 
Anales, xix. Oct. 1861, p. 501. (F. rufifrons .) 
“‘Sobre los gansos chilenos/ Anales, xxi. Nov. 1862, p. 427.
