that Petiver has borne testimony to its regurgitating 
habits. 
There are several species of Ilornbills. All of them 
are natives of the warmer parts of the eastern conti- 
nent — that is, of Africa, of the south-east of Asia, and 
of the eastern Islands. They are generally of a large 
size, and are gregarious, noisy birds. 
The Phinoceros Hornbill {Buceros rhinoceros') is a 
native of India and the Indian Islands, and is to be 
seen in most museums, specimens being often brought 
to Europe. Though there may be some variety from 
age and circumstances, the bill will be generally found 
to be about ten inches long, and of a yellowish-white ; 
the upper mandible red at the base, the lower black. 
The horn, or casque, varied with black and white. The 
body black, of a dirty white below and posteriorly ; 
tail about twelve inches, the feathers white at the base 
and tip, black in the middle ; feet and claws obscure 
grey. The feathers of the cheeks and back of the 
neck are loose and hair-like. 
The Concave Hornbill {Buceros cavatus) is a native 
of the Himalaya Mountains, India, Java, and most of 
the islands of the Indian Archipelago. Its food, like 
that of other Hornbills, consists of fruits, berries, 
flesh, and even carrion ; in short, it may be considered 
strictly carnivorous.^ The throat, ear-coverts, circle 
round the eye, and a narrow band at the occipital 
edge of the protuberance of the beak, black ; neck, 
dirty straw colour, the feathers of the back of tlie 
neck elongated ; body and wings black ; greater coverts 
and quill feathers, tipped with white ; thighs, upper
