x INTRODUCTION. 



B. cristatus ; B. jubatus and B. orient alls from New Holland are not Hornbills ; and B. ruber 

 and B. viridis are copied from Latham and do not belong to this family ; B. coronatus, Bodd., 

 is styled B. violaceus after Shaw; B. melanoleucus, Licht., is called B. coronatus, and 

 B. fasciatus, Shaw, is renamed B. melanoleucus-, B. vigil, Eorst., is called B. galeatus after 

 Latham. The valid species recorded by this author are : — abyssinicus, Bodd. ; vigil, Eorst. ; 

 plicatus, Eorst. ; undulatus, Shaw (as Le calao javan); SYLVESTRIS and LEUCOCEPHALTJS, 

 described for the first time ; melanoleucus, Licht. ; birostris, Scop, (as ginginianus, Lath.) ; 

 griseus, Lath, (referred to New Holland, a wrong habitat) ; panini, Bodd. (as manillensis, Lath.) ; 

 hydrocorax, Linn. (=planicornis, Merr.) ; bicornis, Linn. ; rhinoceros, Linn. ; coronatus, 

 Bodd. (as violaceus, Vieill.), and gingalensis, Shaw (as gingala, Vieill.). All Linnseus's names 

 are referred to Latham, he being apparently the most ancient author consulted. Species 19. 



1820-39. Temminck, Planches Coloriees. 



A monograph of this family as then known is here given, with numerous species described 

 for the first time, the material being supplied from the rich collection of the Leyden Museum. 

 The new species are ten in number, viz. CASSIDIX, ATRATUS, ELATUS, CYLINDRICUS, 

 GALERITUS, CONVEXUS, CORRITGATTTS, EXAEHATUS, ERYTHRORHYNCHUS, 

 and BUCCINATOR. B. stlvestris, Vieill., is renamed lunatus; B. griseus, Lath., is 

 called B. cinerascens ; B. malayanus, Rafil., is renamed B. antracicus. The female of 

 corrugatus is described as B. gracilis. The other species recorded are : — rhinoceros ; sulcatus 

 (=leucocephalus, Vieill.); malabaricus, Gmel. (as monoceros, Shaw); bicornis; abyssinicus; 

 hydrocorax (=planicornis, Merrem); vigil, Eorst. (as galeatus); undulatus, Shaw (as plicatus, 

 Lath.) ; coronatus, Bodd. (as violaceus, Shaw) ; panini, Bodd. (as panayensis) ; gingalensis, Shaw 

 (as ginginianus) ; easciatus, Shaw ; melanoleucus, Licht. (as coronatus, Shaw) ; plicatus, Eorst. 

 (as ruficollis) ; comatus, Rafil. ; and nasutus, Linn. The articles are illustrated with coloured 

 plates of the new species. Species 29. 



1822. Raeeles, in the 'Transactions' of the Linnean Society. 



Two new species are described from Sumatra, B. MALAYANLS and B. COMATUS. 

 Species 31. 



1823. Bonnaterre and Vieillot, Tableau Encyclopedique et Methodique des trois Regnes 

 de la Nature. 



A catalogue of the species is here given, apparently a repetition of that in the < Nouveau 

 Dictionnaire,' with the same errors continued. 



1824. Merrem, in Ersch und Gruber's Encyclopadie. 

 Buceros hydrocorax, Linn., is named PLANICORNIS, which will stand, as Hydrocorax 



is Brisson's genus for the same bird
