LINEATED CUCKOO. 
mage the whole of the chin, throat, and breast, 
which are plain cinereous on the adult, in this are 
banded precisely like the body upon a cream-coloured 
white ground. There is the difference of about half 
an inch in the length of the wings, and the other 
parts are proportionably less. 
Total length, 12j inches; bill, from the gape, 
1 1 % ; ditto, from the front, T 8 5 ; wings, 8^ ; tail, 
beyond, 2^ ; ditto, from the base, 7j 5 tarsus, T 7 5 . 
AFRICAN BLACK CUCKOO. 
Cuculus nigricans , Swain'S. 
Above and beneath black, glossed with blue *, quills internally 
white, with blackish bands ; tips of the lateral tail-feathers 
whitish ; bill and legs black. 
Cuculus nigricans, Zool. III. 2d series. 
Of this very rare Senegal bird, we have never seen 
any other specimen than that figured in the Zoolo- 
gical Illustrations. Its lengthened pointed wings, 
of which the third quill is much the longest, and the 
unusual breadth of its bill (greater even than in 
the common Cuckoo), at once show that it strictly 
belongs to the present genus, even as now restricted ; 
while the black and glossy plumage evinces the close 
affinity between this group and Oxglopkus.
