INTRODUCTION. 



1781. J. E. Forster, Indische Zoologie. 



In this publication, of the zoological portion of which Thomas Pennant is ostensibly the author 

 (but which is probably Pennant's list of English names latinized by Forster), six species of 

 Hornbills are given. They are B. bicornis, Linn., hydrocorax, Linn., rhinoceros, Linn., 

 VIGIL and PLICATUS, named for the first time, and rostratus. This last is referred to 

 Willughby's ' Ornithology;' but as no plate or page is specified, it is impossible to ascertain what 

 bird may have been intended. Although some of the species had been previously described by 

 Linnaeus, the fact appears to have been unknown to Forster, as Edwards, Willughby, and 

 Dampier are the only authors cited. Species 6. 



1783. Boddaert, Tableaux des Planches Enluminees de d'Aubenton. 



Pounding his species upon the plates of Bufibn's work, to which he gives Latin names, the 

 present author records four species not before noticed. They are B. COBONATUS, B. PANINI, 

 B. MANILLA, and B. ABYSSINICUS ; all valid. Species 10. 



1786. Scopoli, Deliciae Florae et Faunae Insubricse. 



Three species of Hornbills are given in this work, one of which is recorded for the first time, 

 viz. B. BIBOSTBJS, which is the ginginianus of authors. The remaining two are B. panayensis, 

 (=panini, Bodd.) and B. pica (=B. coronatus, Bodd.). Species 11. 



1788. Gmelin, edition of Linnseus's * Systema Naturee.' 



Twelve species are enumerated by Gmelin, only one, however, for the first time. They are 

 bicornis, abyssinicus, africanus (= abyssinicus, Bodd.), MALABABICUS (first distinguished as 

 distinct from coronatus, Bodd.), Jiydrocorax (=planicornis, Merrem), rhinoceros, galeatus 

 (=vigil, Forst), panayensis (=panini, Bodd.), manillensis (=manill^, Bodd.), nasutus, alius 

 (an albino of some bird not belonging to this family), and obscurus (=plicatus, Forst.). 

 Species 12. 



1790. Latham, Index Ornithologicus. 



Sixteen species of Hornbills are here given, only one named for the first time. Nine are 

 valid, the remainder either impossible to determine with certainty, or synonymous with other 

 previously described species. They are B. rhinoceros, B. galeatus (=vigil, Forst,), bicornis, 

 abyssinicus, africanus (=abyssinicijs, Bodd.), malabarictts, Jiydrocorax (=planicornis, 

 Merrem), panayensis (=panini, Bodd.), manillensis (=manill^, Bodd.), nasutus, plicatus, 

 ginginianus (=birostris, Scop.), GBISEUS, named for the first time, and albus 3 orientalis, and 

 viridis not of this family. Species 13. 



1793. Lichtenstein, Catalogus rerum naturalium rarissimarum auctionis lege distrahendarum 

 Hamburgi. 



TOCKUS MELANOLEUCUS is here described. Species 14.
