720 Mr. W. L. Sclater on Birds collected 
appear to be its principal food, and it is often observed on 
the ground hunting for its prey, especially on burnt-off 
patches. Its cry is a single, low, melancholy note, not 
greatly dissimilar to that of L. leucomelas. 
The soft parts of the adult are:— 
$. Irides reddish brown; bare skin round eyes and base 
of cheeks adjoining the lower mandible sooty black; bill 
black, with a long yellow patch on the upper mandible, 
extending from the base under the nostril to over half the 
length of the mandible, and three or four yellow transverse 
lines on the lower. Legs and toes black. 
? . Irides as in male; bare skin round eyes and base of 
cheeks browner; bill, upper mandible at base pale yellow, 
along cutting-edge and apical portion dull dark red; lower 
mandible, basal two-tliirds black crossed with four pale 
yellow lines, apical portion dull dark red. Legs and toes 
as in male. 
In neither sex does the colour of the bill alter after death.] 
431. Lophoceros erytiirorhynchus. 
P. Tete, Aug., Sept. (4 and one head). 
[“Nyumdero” of the Njungwis. 
Around Tete and south of Makumbi’s country to about 
the 18° south latitude, on my return trip to the coast, this 
species was found. It was generally in small flocks of 
half a dozen individuals and was somewhat wary. Every 
morning flocks would pass over, coming out of the back 
country and making towards the rivers, where they spent the 
day, presumably to feed on the wild fruit and berries and 
to rest in the shade of the leafy trees that line the banks— 
for, as it was the dry season, the only leafy vegetation was 
near the river; they passed back again towards sundown, 
each flock regularly taking the same course, so that it was 
then by a little waiting that specimens could be secured. 
The flight is easy and graceful, with a few flaps of the 
wings, accompanied by the long glide so characteristic of 
the Hornbills. The cry is a single note, low and clear, and 
almost a whistle.
