[Eeview of the Birds collected by Alcide d'Orbigny in South 

 America. By C. E. Hellmayr. Part I. Nov. Zool. Tring, xxviii. 

 1921, pp. 171-213.] 



Alcide d'Orbigny (1802-1857) was a well-known French 

 traveller and naturalist in the early part of the last centuiy. 

 During the years 1826-1833 he travelled and collected 

 extensively on behalf of the French government in the 

 south-western part of South America, and transmitted to 

 the Paris Museum large numbers of objects of natural 

 history. The account of the journeys and collections was 

 published in a series of large quarto volumes between 1835 

 and 1847, but unfortunately was never completed. He also, 

 with the co-operation of his countryman, M. H.deLafresnaye, 

 published a preliminary list of the species of birds obtained 

 in the ' Magasin de Zoologie,' but this, too, remained in- 

 complete. While most of the birds collected by d'Orbigny 

 are to be found in the Paris Museum, some remained in the 

 possession of Lafresnaye and have now found their way to 

 the Museum of Comparative Zoology in Cambridge, Mass. 



Dr. Hellmayr has now undertaken the difficult task of 

 revising and commenting on d'Orbigny's work, for which 

 purpose he made a number of visits to the Paris Museum 

 before the war, and in the present paper he gives us the 

 first part of the results of his long labours. The present 

 instalment deals with the Birds of Prey and a small moiety 

 of the Passeres. The original d'Orbigny specimens, many 

 of them mounted, are listed and re-identified and compared 

 with other examples at Tring and elsewhere. The paper 

 is a most important one for all workers on Neotropical 

 ornithology.

M. Lavauden has given us here a careful critical study of 

 the various forms of Peregrine found round the Mediter- 

 ranean. He has made a thorough examination of the
