The first Latin name given to this species is in the " Faunula Indica " of Forster's ' Indische 

 Zoologie,' where the appellation of plicatus is conferred upon the Hornhill the head of which is 

 represented in Dampier's plate, published in the third volume of his ' Voyages/ page 23L This 

 bird was said to have come from Ceram ; and, from the fact that the bill had no lateral ridges upon 

 either maxilla or mandible, it is without doubt the present species, called afterwards ruficollis by 

 Vieillot, and generally known to ornithologists by the latter name. The other prominent synonyms 

 of the species are obscurus, Gmelin, and Wreathed Hornbill or Buceros plicatus, Latham. 



The " Wreathed Hornbill " of Latham (I. c.) was founded upon a drawing of a bill given in 

 Ray's translation of Willughby's ' Ornithology,' and which, having no lateral grooves, must have 

 belonged to the present species. To this Gmelin gave the name of obscurus (I. c); and two years 

 afterwards Latham also gave to his Wreathed Hornbill a Latin title, and called it in his e Index
