error, however, I shared in common with Professor Sundevall

Nottingham, August 29tli, 186G. 

 Sir, — I regret to say that an error has crept into Dr. Hart- 

 laub's account of Phlexis 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 Sii', &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 fiir 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 ' 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 ' thus far received 

 by the Smithsonian Institution are as follows : — 



" ' Descripcion de una nueva especie de pajaros del jenero 

 Thalassidroma' Anales, xviii. Jan. 1861, p. 27. {T. segethi.) 



"'Descripcion de una nueva especie de pajaros del jenero 

 Cwprimulgus,' 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 chilcnos del jenero Tidica' {Fulica), 

 Anales, xix. Oct. 1861, p. 501. {F. j'ujifrons.) 



"'Sobre los gansos chilenos,' Anales, xxi. Nov. 1862, p. 427.
