be heard a long way off. They are generally seen in small flocks of 
from three to six individuals. 
“The Ovampos seem to have a superstition about this curious bird, 
which I cannot fathom. On asking Chijkongo, for instance, to get 
me the eggs, he said it was not to be done, as they were soft to 
the touch, and would fall in pieces on the least handling !’’ 
Senor Anchieta records it as plentiful at Humbe on the Cunene 
’ River, where it is called ‘ Mucungungo’ by the natives. He has also 
sent it from Quillengues in Mossamedes. 
A very good account of the habits of the Ground Hornbill is given 
by Mr. Monteiro in his paper on the birds of Angola, (Ibis, 1862, 
p- 38.) 
This species is distinguished by its large size and compressed 
casque. Total length of wing about 19 inches. The colour is black 
all over, with the exception of the primaries, which are white. Mr. 
Ayres states that the iris is very light brown, the legs and the bill 
black, the bare skin of the neck and round the eye bright red; the 
female is said to have the bare parts blue. Senor Anchieta who has 
forwarded several specimens to the Lisbon Museum, gives the follow- 
ing account of the soft parts :—~ The region round the eye, the neck 
and pouch on the throat, are yellowish, more or less mixed with 
orange or red. One of the females has a large spot of blue-black 
on the gular pouch, and in two other birds of the same sex, there is 
plainly observable an elongated spot of dark blue on each side of the 
neck, below the angle of the lower mandible. The young bird has 
these parts of a yellowish red without any mixture of blue.” For 
figures of the heads of all the African Ground Hornbills see the paper 
by Professor Barbosa du Bocage (P. Z. 8. 1873, p. 698.)

By no means a common species in collections. Victorin met with 
it at the Knysna in June and July, and it has been forwarded to us 
by Mr. Henry Bowker, who procured it in the Transkei country. 
His sister, Mrs. Barber, informs me that it “is a very wild and shy 
bird, and difficult to shoot.” It has been procured in Natal by Mr. 
Gueinzius, and regarding its occurrence in the Zambesi, Dr. Kirk 
writes as follows :—“ Rather common both in the mountains and
