Hodgson states, from comparison of many specimens, that the 

 body of the Homrai does not reach its full size under two or three 

 years; and that the bill and casque, especially the latter, are not 

 •perfectly developed in less than four or five years. Blyth, how- 

 ever, from observation of a living specimen, that attained its full 

 development in captivity, is of opinion that about three years is 

 the full time required. 



The generic name Buceros has been retained for B. rhinoceros^ 

 L. from the Malayan Peninsula and the nearly allied species B. 

 lunatus, T. from Java. B. hydrocorax, L., a large red-billed 

 Hornbill from the Moluccas, has been separated as Hydrocorax, 

 Bonap., for which Cabanis substitutes Platyceros.

Char. — Bill with a long, sharp, acute casque, extending from the
