Expedition to the Zambesi River . 93 
■ Adult. Total length (measured in flesh) 8’5 inches, wing 
5*8. Iris hazel; bill black ; legs and feet dark brown. 
Our four specimens are all adults. 
123. Ch^tura stictil^ma (Reichen.). 
Only once observed, near Zumbo on November 8, when a 
small party of six birds appeared and remained in the vicinity 
for two days, leaving again on the third day. The flight is 
remarkably powerful, while at the same time the white rump 
is very conspicuous. 
Adult (Zumbo, November 8). Total length (measured 
in flesh) 5*5 inches, wing 5 - 7, culmen 0*3. Iris black; bill, 
legs, and feet black. 
124. Tachornis parva (Licht.). 
Found in colonies along the river, but not numerous. On 
landing at a small Kaffir village near Senna, on July 22, 
we found a colony of these Swifts had taken possession of 
the palm-trees that grew close to the huts, around which 
they flew incessantly. They were evidently building, for 
numbers kept flying up into the cups of the palm-leaves, the 
next moment to dart away, and this went on without ceasing, 
a continued string of birds flying up to and down from the 
leaves of these tall coconut-trees. 
125. Caprimulgus possii (Hartl.). 
Found in a variety of places. Waste land partially over¬ 
grown with reeds near the river, localities covered with thick 
long grass, and open stony portions of ground in the thick 
woods were common to the Nightjar, which we frequently 
flushed during the daytime. 
Senna, July 24.—Towards dusk a large number of Night¬ 
jars came abroad and flitted to and fro over some low-lying 
ground bordering the river. They would often alight on 
the native paths in front of us and then start up at our feet 
in a noiseless manner, only to pitch again a few yards ahead. 
And numbers kept flying backwards and forwards over a bed 
of thick fish-cane with a flower of a fluffy nature that no doubt 
attracted moths. The bottom of this cane-growth resounded 
with the clear croak of innumerable bullfrogs, and when it
