Adult. Very close to L. mossambicus, but with the under parts pure 
white and without a trace of the rosy tinge, at any rate in the adult; as a 
rule the white spotting on the rump is rather conspicuous and extends for- 
wards on either side to the scapulars; usually the three inner secondaries, 
but sometimes only two, are broadly edged with white. ‘Iris dark brown, 
bill black, feet slaty blue” (Ansorge). Length 8-5 inches, wing 3°8, tail 3:5, 
tarsus 1:35, culmen 0:90. N’Dalla Tondo, ¢, 26.9.08 (Ansorge). A very 
large male from Lake Ngami (Woosnam) has the wing 4°3 and tail 4:2. 
The Angola Boubou ranges from the Portuguese Congo 
south to the Cunene and eastwards to the Victoria Falls 
country and to Lake Ngami. Further east and north-east in 
Katanga and the neighbourhood of Lake Mweru it merges 
into the Mosambique Boubou, while to the north it becomes 
Li. bicolor. 
The type of the species, now in the British Museum was 
described by Hartlaub and was obtained by Monteiro on the 
coast lands of Benguella; Anchieta met with it in many local- 
ities throughout Angola, and states that it is there known to 
the natives as “Sequi” or “ Gongo.” Bocage believed that he 
could distinguish two additional species in Angola. L. finschit 
with a white edging to the outer web of the outer tail-feather, 
and L. neglectus with three, not two, of the secondaries white- 
edged, but the former character is no doubt a juvenile one, 
and the latter is very variable, the right and left wing of 
individual birds often differing in this respect. 
Hartlaub’s L. sticturus was founded on a Boubou from 
Lake Ngami and is also characterized by having three of the 
inner secondaries white-edged as well as white spots on the 
tail-tips. The latter character is not present in fully adult 
examples from the same locality, though the former seems to
