As before mentioned the male of this species is so similar to that 
of B. molitor, that a slight difference in size seems to be the only 
character for separating them. The females are quite unlike each 
other, and we believe that any one comparing the hen of the present 
bird with the plate in Le Vaillant’s work will see that this is the 
“ Pririt” figured by him. Mr. Ortlepp has procured it near Coles- 
berg, and the only other localities whence we have seen specimens 
are Benguela and Damara Land. Mr. Andersson observes :—“ This 
species is very abundant in the Swakop valley ; it is usually seen in 
pairs about large trees, which it explores carefully and systematically 
in search of insects. It has at times a peculiar far-sounding note, 
which a stranger might imagine to be uttered by a bird at a great 
distance, whilst, in reality, the bird is near at hand.” 
Adult male.—Indistinguishable from B. molitor in colour, but a 
little smaller ; “iris light lemon-yellow on the inner edge, shading 
off into greenish grey in the outer circle” (Andersson). Wing, 2°15. 
Adult female.—Above clear bluish grey, the rump mottled with 
white; sides of neck and nuchal spot clear orange buff; a narrow 
superciliary line of white from the base of the bill; lores, feathers
