The famous Austrian naturalist Johann Natterer, wbose name I have so often mentioned in this 

 work, was the discoverer of this fine species, although (owing to his untimely death and to the 

 consequent delay in the publication of his discoveries) it does not bear the name which he gave 

 to it in his MS. journal. Natterer obtained altogether twelve examples of this bird during his 

 journeys up the Eio Negro and in the vicinity of Para in 1831 and the succeeding years, and 

 designated it " giganteus," remarking that it differs from B. macrorhynchus in its larger size, its 

 much longer and thicker beak, and the extension of the white forehead over the anterior part of 

 the head. Natterer, as quoted by von Pelzeln, states that in the fresh bird the " bill is black, 

 as likewise the eye-ring and naked space round the eye ; the iris carmine-red, darker on the outer 

 half; the feet very dark bluish-grey, toes blackish, and claws black." Natterer procured his 

 examples at Fort San Jose de Marabitanas, on the Upper Eio Negro, on the Rio Curicuriari (a 

 small confluent of the last-named river), and at two localities near Para. 



In the last-named locality two other well-known naturalists have likewise obtained examples
