on the back (specimens Nos. 3044, 3141, and the bird 
obtained by Bates at Efulen, B. M. Beg. No. 1903. 
7.16.30, erroneously named C. clamosus by Sharpe 
in 4 The Ibis ' (1904, p. 614). 
3. The third represents the almost adult stage; the under¬ 
parts have lost all trace of the black feathers except 
on the thighs, the breast is creamy-buff barred with 
black and the chin and throat chestnut barred 
with black. The upper parts are glossy throughout 
(specimens Nos. 4411, 3616, 4091, and 951 [Bates 
Cameroon coll.], No. 14, ex Shelley coll, from 
Landana, and specimen 1919.10.12.46, Poko, TJele, 
Dr. C. Christy coll.). 
4. In the fourth we see the fully adult bird which has lost 
all trace of barring on the throat, which is now 
uniform chestnut (specimens No. 4291 [Bates coll.] ; 
No. 805, Landana [Shelley coll.] ; and two birds col¬ 
lected in Gaboon, Danger K. [Ansell], “Gaboon” 
[Verreaux]). The ground-colour of the breast is 
creamy-buff, and the under tail-coverts are uniform 
buff, with little trace of barring. 
. The range of C. g. gabonensis appears to be from Cameroon, 
through Gaboon south to Landana just north of the mouth 
of the Congo Biver, and eastward to the northern Belgian 
Congo, Uele Biver district. 
CUCULUS SOLITAIIIUS.

1815, p. 84—Type locality : Caffraria ( i . e. Eastern Cape 
Colony) ex Levaillant.] 
Next we will deal with Cuculus solitarius, another Cuckoo 
which ranges throughout Africa and occurs in Cameroon. 
Mr. Bates's last collection contains very young birds of this 
species, which shows that it should never be confused with 
C. gabonensis. In the British Museum we have a large 
series of this bird :—89 in adult plumage and 14 in
