1801. Le Vaillant, Histoire Naturelle d'Oiseaux Nouveaux et Bares de l'Anierique et des 

 Indes. 

 In this work ten different Hornbills are given, illustrated by twenty-three plates of heads 

 and figures of the entire bird. The nomenclature is French; and so some species represented here 

 for the first time were characterized afterwards by other writers under Latin names. The species 

 given are :-— bicornis, Linn.; planicornis, Merrem; coronatijs, Bodd. ; sylvestris, Vieill. ; mala- 

 baricus, Gmel. ; birostris, Scopoli; panini, Bodd. ; plicatus, Eorst. ; and gingalensis, Shaw. 



1806. Le Vaillant, Histoire Naturelle des Oiseaux d'Afrique. 



As in the preceding work, the author employs French names. Nine species are mentioned, 

 illustrated by plates ; but the opportunity was lost for giving any of them a specific rank in the 

 science. 



1808. "Wilkes ?, Encyclopaedia Londinensis. 



In this publication, of which in the octavo edition five volumes are devoted to prnithology, 

 numerous species figured by Le Vaillant in his different works have Latin names given to them, 

 some for the first time ; and did we but know the author, they would take precedence of all those 

 subsequently bestowed upon the species. No author's name, however, having been given, 

 unfortunately none of the appellations can be recognized. It is unnecessary, therefore, to 

 make further reference to the list. 



1811. Shaw, General Zoology. 



A list of the species as known to the author is given, compiled chiefly from Latham and 

 Le Vaillant, and Latin names affixed to those previously only recognized by French or English 

 appellations. Twenty-five in all are noticed, only fourteen of which are valid. B. mala- 

 baricus, Gmelin, is twice renamed, as B. monoceros and B. albirostris ; B. coronatus, Bodd., 

 is called B. molaceus ; B. bicornis, Linn., is styled B. cavatus ; B. UNDLLATUS is described 

 for the first time; B.javanicus (=undtjlatus); B. melanoleucus, Licht., is named B. coronatus ; 

 B. GINGALENSIS and B. EASCIATUS are given for the first time. Species 17. 



1811. Bechstein, Kurze Ilebersicht aller bekannten Vogel. 



A catalogue of seventeen species of Buceros is given, with descriptions. Eour are not valid, 

 viz. B. africanus (=:Abyssinicits, Bodd.), B. alius, B. orientalis, and B. viridis (ex Latham) not 

 belonging to this family. No new species are described. 



1816. Vieillot, Nouveau Dictionnaire d'Histoire Naturelle. 



In the fourth volume of this work is a list of the then known species, two of which are 

 described for the first time, viz. the Javan form of B. rhinoceros, founded upon the Calao a 

 casque en croissant of Le Vaillant, and called B. SYLVESTBIS, and B. LEUCOCEPHALUS. 

 B. PLICATUS, Eorst., is renamed twice, as B. ruficollis and B. niger ; B. bicornis, Linn., is called
