Expedition to the Zambesi River. 
Adult S (Zambesi). Total length (measured in flesh) 4*68 
inches, wing 2‘0, culmen 0'4, tail T98. Bill black; iris 
orange; legs and feet brownish flesh-colour. 
Adult $ (Kingwilliamstown). Wing 1*9 inch, culmen 
0-48, tail 2*0. 
84. PniNIA MYSTACEA (Rupp.). 
Fairly common. At the end of August small flocks of 
young birds in their first plumage, but in the process of 
moult, were frequently observed. On August 26 a party 
of these birds visited the confines of our camp, and with 
their inordinately long tails, which were raised ever and anon 
to a sharp angle with their bodies, they reminded us very 
forcibly of a band of Long-tailed Tits as they flitted from one 
low bush to another, always keeping close to the ground 
in their journey, and only on being disturbed would they fly 
up to the top of some tall tree and utter harsh little notes 
of alarm. 
In November and December we obtained specimens in 
adult plumage. 
Immature $ (August 26). Total length (measured in 
flesh) 5 '7 inches, wing L9, tail 3*2. Iris orange; bill black, 
horn-colour at tip; legs and feet flesh-colour. 
Adult $ (November 13). Total length (measured in 
flesh) 5’0 inches, wing 1*86, tail 2*3. Iris orange; bill black ; 
legs and feet flesh-colour. 
Adult ? (July 19). Wing 1*8 inch, tail 2T. Iris orange; 
bill black ; legs and feet flesh-colour. 
The last-named specimen had organs in breeding condition. 
The breeding-season would therefore appear to be from May" 
onward. In August the young of the year, easily recog¬ 
nizable by their long tails, are abroad, and by the end of 
December they have practically assumed the adult plumage, 
while in the second year breeding takes place. 
85. CiSTICOLA LUGUBRIS (Rupp.). 
Only once met with at Shupanga on July 7. We had 
some difficulty in obtaining any of these handsome little 
Cisticolas, which were then in full breeding-plumage. They
