natives as the ‘“Caxingo-anguluvi,’ “Kitikenene” and 
“Quitiaquenene,”’ and at Galanga as the ‘“ Culumbamba.” 
The only authority I find for its ranging eastward rests on 
two specimens from Songwe (Fiilleborn) described by Dr. 
Reichenow as immature birds of this species, and he further 
suggests that a bird from Lugoma (Béhm) possibly also belongs 
to this species. I am inclined to doubt both of these latter 
localities (Songwe and Lugoma) for the present species, for I 
think that the specimens, immature birds, more probably 
belong to N. nigritemporalis. 
The British Museum contains only two examples of this 
species from Caconda, the type locality, collected by Anchieta ; 
but in the Tring Museum there are others from Bihé, the 
Karunge River, Duque de Braganza, Makwata and Pungo 
Andongo, all places in central Angola where it was collected 
by Ansorge. 
Genus III. SIGMODUS. 
Bill red or orange in adults, moderately strong, with the upper mandible 
strongly hooked and with a notch near the end. Nostrils horizontal with a 
slight overhanging membrane, nearly or entirely covered by the bristly 
frontal plumes, which form a slight crest. Eyelids generally very wide and 
provided with small fleshy wattles of a yellow, red or dusky grey colour. 
Wing fairly long, but rounded, the secondaries falling short of the tip of the 
wing by less than the length of the tarsus; primaries fourth and fifth longest, 
second equal to tenth and first more than half of second. Tail slightly 
rounded and shorter than the wing. Tarsus scaled behind, and orange or 
scarlet like the feet.

The genus is confined to Tropical and South Africa, and comprises ten 
species and subspecies. Its members may be easily recognized by the red 
bill and legs of the adults.
