by his friend, and to some particulars extracted from 

 Jacquin's then unpublished description of his supposed 

 species, a synonym from Marcgravf which can alone 

 justify M. Temnnnck's criticism. We restore without 

 hesitation both these synonyms of Linnaeus and Jacquin, 

 excluding only from the twelfth edition of the Systema 

 Naturae the references to Marcgrave and his copyists. 

 With the Vultur Harpyia of Linnaeus and the Vultur 

 coronatus of Jacquin, are necessarily included among 

 the synonyms of the Harpy Eagle the Falco Harpyia 

 and the Falco Jacquini of Gmelin, by whom the trivial 

 name assigned by Jacquin to his bird was changed on 

 account of its introduction into a genus in which that 

 appellation was preoccupied. 



In the year 1778, Mr. Dillon observed in the Mena- 

 gerie of Buen Retiro at Madrid, a species of Eagle, 

 which he imagined to be " an undescript bird not taken 

 notice of by Linnaeus." This bird, which he figures in 

 his Travels through Spain, under the name of the 

 Crested Falcon, is evidently of the same species with 

 the Harpy, although the representation is rudely exe- 

 cuted, and in some respects, as for example the length 

 of the beak, grossly caricatured. We might almost be 

 tempted to suspect that the specimen seen by him was 

 identical with that described by Linnaeus from the same 

 menagerie twenty years before, were it not that the 

 latter bird is expressly called Mexican, while that of 

 Mr. Dillon is stated to have come from the Caraccas. 

 For this reason Dr. Latham introduced it into his 

 Synopsis under the name of the Caiacca Falcon. Gme- 

 lin, quoting from Latham, soon after latinized its former 

 name into Falco cristatus, and this may therefore be 

 added to the synonyms of our bird, of which Mr. Dil- 

 lon's was the first published figure. 

 The next original describer of the Harpy Eagle was
