THE HARPY EAGLE. 263 



Aiauduyt, who also regarded his specimens as nonde- 

 script, and gave them the name of Grand Aigle de la 

 Guiane, from the country whence they Avere obtained. 

 To these birds, which formed part of the collection of 

 the Paris Museum, Daudin, in his Ornithology pub- 

 lished in 1800, applied the scientific appellation of 

 Falco Destructor; and the names given by these two 

 writers have been generally adopted on the continent 

 of Europe as the only ones certainly applicable to the 

 species. M. Sonnini seems doubtful whether or not to 

 regard the two specimens described by him as distinct 

 species, and names the one Aigle Destructeur, and the 

 other Grand Aigle de la Guiane ; but there seems no 

 sufficient reason for their separation. Dr. Shaw's Falco 

 imperialis is founded on this indication of Sonnini, In 

 all probability the Crested Eagle of Stedman's Expe- 

 dition to Surinam, spoken of as a very strong and fierce 

 bird, belongs to the same species. Figures of the Harpy 

 are likewise given by M. Cuvier in his Regne Animal; 

 by M. Vieillot in tlie second edition of the Nouveau 

 Dictionnaire d'Histoire INaturelle ; in the Dictionnaire 

 des Sciences Naturelles ; and by M. Temminck in his 

 Planches Coloriees. Those of the two last-named works 

 are strikingly characteristic. That of the Dictionnaire 

 exhibits the crest-feathers equally and stiffly elevated 

 round the back part of the head, a state in which we 

 have never seen them in our bird, and which, on account 

 of their laxity, and the lower position of the middle 

 ones, we doubt their power to assume. It is riglif, 

 however, to remark that the crest is stated by Linnspus 

 and other authors to possess this power of elevation 

 round the head in form of a crown, an ornament alluded 

 to in the Spanish name of the bird, Aguila coronada, 

 and in the trivial appellation, coronatus, afiixed to the 

 species by Jacquin.
