138. Rhinopomastus cyanomelas (VieilL). 
A scarce bird, observed either singly or in pairs, and 
travelling through the woods with a Magpie-like flight. 
They are silent birds and are always busy destroying the 
freshly-opened buds of the trees with their scimitar-like 
bills, and when thus employed they have a pretty way of 
hanging from underneath the branches. We obtained an 
immature bird on August 22, while in December the adults 
were undergoing their moult. 
139. Bucorvus caffer (Bocage). 
Seen only once, but not obtained. 
140. Bycanistes buccinator (Temm.). 
Observed near Shupanga in company with B. cristatus, 
but only one specimen procured. It was seen at rare 
intervals in small parties and generally towards evening as 
it journeyed from the thick woods to the river, where it 
roosted in the deciduous trees lining the bank. We could 
always tell when these birds had started from their close 
daytime retreats on their journey towards the water, which 
was accomplished in stages, by their loud peculiar cries, that 
could be heard at a great distance and might be likened to 
the bleat of a lamb. It is a comical sight to see one of 
these birds alight on the top of a tree. Its heavy bill and 
enormous casque cause it almost to topple over, but the 
bird just saves itself by bringing down its strong and flexible 
tail to a sharp angle. 
Adult 6 . Bill and casque blackish; iris brown; soft 
parts pinkish flesh-colour ; legs and feet dark brown. In 
life, the end of the casque behind the eye is soft and almost 
pulpy. 
141. Lophoceros melanoleucus (Licht.). 
Common. Frequenting in parties belts of thick deciduous 
trees lining the river's bank, and flying forward in batches 
on one's approach with an out-and-in flight. The alarm- 
note is squeaky and weak for the size of the bird. 
This Hornbill is very fond of the “ masau " apple fjujuba-
