132 BIRDS OF SOUTH AFRICA. 
Anchieta has forwarded specimens from the Cunene River (Humbe), 
where it is called Sunguiandondo, and he has also met with it at 
Huilla and Capangombe in Mossamedes. 
Of its habits, Mr. Andersson writes :—“ This Hornbill is frequently — 
seen searching for food upon the ground ; and the way in which it 
swallows some kinds of food is peculiar, raising its head and pitching 
the morsel into the air, receiving it again into its bill, and repeating 
the process several times, perhaps with the object of softening the 
food or reducing it to a pulp.” 1 
Top of head grey; forehead, cheeks, a line half-way down tke 
middle of back, some spots upon the shoulders, some of the inner 
wing-feathers, more or less of the three outer tail-feathers, and all 
the under parts, white ; outer wing-feathers black, with some white 
markings; four inner tail-feathers and rump black ; iris light yellow; 
bill deep red, elongated, curved, sharply keeled above, not casqued, 
3} inches long. Total length, 19’’; tail, 7”; wing, 7’’ 6'”’. 
Some specimens appear to have the cheeks grey. Mr. Gurney 
writes of a female from the Limpopo :—“ In the specimen sent the 
cheeks were dark bluish grey, not white, as described by Mr. Layard 
(B. 8S. Afr. p. 227.) I believe that both these variations of colour 
occur in South-African examples of this bird, but whether they are 
indicative of distinct races I am unable to say.” In a note to this 
species in Mr. Andersson’s work, Mr. Gurney further writes :—“ Two 
of these examples (a white cheeked bird from Objimbinque, and a 
grey cheeked one from Ovampo Land,) are preserved in the collection 
of Mr. R. B. Sharpe ; and as both of these were marked as males by 
Mr. Andersson (no doubt from dissection,) and as both of them from 
the character of their bills are evidently adult birds, it follows that 
the difference is not due either to age or to sex. Professor Sundevall, 
from his remarks at p. 130 of the ‘Ofversigt? for 1850, appears to 
consider the grey plumage of the cheeks to be especially characteris- 
tic of what he considers the Caffrarian race, for which he has pro= 
posed the specific name of ‘rufirostris’ On the other hand, Mr. 
Jules P. Verreaux informs us.that he considers that both birds are 
of one and the same species, and that the pure white on. the cheeks _ 
and the parts adjacent is a nuptial dress annually assumed and lost - 
by a double seasonal change.”
