Note on the correct generic name of Podiceps minor. 



In Mr. G. R. Gray's ' Catalogue of British Birds ' (1863) 

 and elsewhere Sylbeocyclus is given as the first generic term 

 applicable to Podiceps minor. The invention of the name is 

 assigned (p. 213) to " Bonaparte, 1832," but no reference is 

 added. 



Upon looking into the matter I find that this curious name* 

 appears to have been first used by Bonaparte in 1834 in the 

 supplementary remarks to his ' Saggio di una distribuzione 

 metodica degli Animali Vertebrati/ p. 144. But the type 

 given is P. carolinensis ; so that Sylbeocyclus is merely a 

 synonym of Podilymbus, proposed by Lesson for the same 

 type in the same year. 



In Gray's first 'List of Genera' (1840) P. minor is given 

 as the type of Sylbeocyclus. In the second edition of the 

 same work (1841) the name is correctly placed as a synonym 

 of Podilymbus. In the ' Catalogue of British Birds/ as above 

 mentioned, and in the ' Hand-list/ the former course is again 

 adopted. But in the ' Hand-list/ under Podilymbus (iii. 

 p. 95), is added ''Sylbeocyclus, Bp. 1856, nee 1832." This 

 should perhaps be " Bp. 1834 nee 1838j" for in his 'Compa- 

 rative List,' published in the latter year, Bonaparte uses Syl- 

 beocyclus for both P. minor and P. carolinensis. But it is 

 clear that he knew that this was an error j for in his ' Cata- 

 logo Metodico degli Uccelli Europei,' published in 1842 (p. 83), 

 Bonaparte reassigns P. minor to Podiceps, and adds "mi- 

 nime Sylbeocyclus err. typ." 



It is therefore certain that Sylbeocyclus = Podilymbus, and
