III. Nomina nuda or Names not proposed in a Generic 



Sense. 



Fregata Briss. 1760, becomes Fregata Laeep. 1799. — Brisson 

 did not use the name in a generic sense. 



Nycticorax Raf. 1816, becomes Nycticorax Forster, 1817. — 

 Rafinesque's name is a noinen nudum. Type (only species), Ardea 

 nycticorax L. 



Botaurus Herm. 1783, becomes Botaurus Stephens, 1819. — 

 Hermann did not use the name in a generic sense. This was 

 first done by Stephens, Gen. Zool., vol. XI, p. 592. Type from 

 Forster (first species), Ardea stellaris L. 



Macrorhamphus Leach, 1816, becomes Macrorhamphus 

 Forster, 1817. — All the new genera in Leach's Catalogue are 

 nomina nuda, but all can be cited from Forster's Catalogue of 

 the next year, where Linnaean equivalents are given, unless some 

 ■other work intervenes. 



Pavoncella Leach, 1816, becomes Machetes Cuvier, 1817, 

 (Regne Animal, I, p. 490). — Cuvier' s Regne Animal was prior to 

 Forster's Catalogue. Type the same. 



Calidris Cuvier, 1800, becomes Calidris 111 ger, 1811. — Most 

 of the new generic names of the Tableau in Lecons Anat. Comp. 

 are nomina nuda, as they are accompanied only by a vernacular. 

 Where, however, the vernacular was used in the Tableau Element., 

 1798, in conjunction with an identifiable binomial name, Dr. J. A. 

 Allen suggests that it should be accepted; the species mentioned 

 becoming the type. Thus while Calidris is a nomen nudum, 

 Regulus is tenable since it is called "Roitolet" in 1800, and in the 

 Tableau Element., 1798, we find "Roitolet, Motacilla regulus L.," 

 showing exactly what the genus was based upon. 



In the same way, while most of Brehm's genera, in his paper in 

 Isis, 1828, are nomina nuda, we can retain " Archibuteo, Rauchfuss- 

 buzzard," since it is clearly identified in his earlier Beitrage Vogel- 

 kunde, 1820 — viz., "Der Rauchfussige Buzzard, Falco lagopus 

 L." 



Urubitinga Lesson, 1839, becomes Urubitinga Lafr. 1843. — 

 This name occurs only as a nomen nudum in Rev. Zool., 1839, 

 p. 132. Dr. Richmond gives me as the earliest citation known to
