This species does not appear to visit even the eastern districts of 
the colony, and in the western portions it has never yet been found. 
It has been stated by Dr. Hartlaub and Professor Schlegel to inhabit 
Caffraria, and a specimen is recorded in the Leiden Museum as 
having been procured by Wahlberg in the “ Makkalis Mountains.” 
Tn the Transvaal it is more frequent, and Mr. Ayres writes as fol- 
lows:—‘‘ This species is common along the Limpopo; and I have also 
received it from Megaliesberg, a range of wooded mountains about 
seven miles from Potchefstroom. Like T. flavirostris, this Hornbill 
is a great fruit-eater, lives in small companies and has a dipping 
flight. I was much surprised to find one of these birds, perched on 
the top of a small tree, singing very prettily with the voice of a 
Thrush. I could scarcely believe my ears, until I had watched the 
bird for a considerable time: at last he flew away, and the woods 
were silent.” Mr. F. Barratt has a specimen from Oliphants Nek, 
Mr. T. E. Buckley shot specimens in Bamangwato, and Dr. Exton 
observed the species at Kanye in the Matabili country. He says :— 
_ “They are generally found in the early morning feeding on the 
ground under trees. The stomachs of those I procured were filled 
with berries, seeds, and insects (sand-wasps).” Dr. Kirk mentions 
haying seen the species in the Shire Valley, but it appeared rather 
rare in the Zambesi. Mr. Andersson give the following account of 
it :-— This species does not occur in Great Namaqua Land, but is 
found in Southern Damara Land, where, however, it is far from 
common and excessively shy; in the northern parts of Damara 
Land it is less shy and very common ; and it is also to be met with 
in the Lake-regions. It is seen in small families rarely exceeding 
half a dozen individuals. It roosts on large trees if such be within 
reach, generally returning nightly toa fixed roosting-place ; it usually 
perches upon trees about halfway up, and, unlike 7. melanoleucus 
and T, flavirostris, rarely alights on the topmost boughs. In com- 
mon with the rest of the genus it appears to suffer very much from 
_ the heat during the most trying season of the year, when it may be 
found perched at noon in the shadiest part of the forest, gasping as
