Birds of Southern Kamerun. 
634. Cercococcyx mechowi. [Mon-Obam.] 
Sharpe, Ibis, 1907, p. 436. 
This smaller Cuckoo with the remarkable tail closely 
resembles in some of its call-notes the common larger Cuckoo 
just mentioned. It also says “ Za-so-foe ” in a similar 
manner, though in a higher tone of voice. I have heard 
one of these birds making this call, and uttering at the same 
time other interpolated notes that seemed to be peculiar to 
itself. It appears to imitate the call of Cuculus gabonensis, 
which in its turn seems to imitate that of C. solitarius. 
The food of Cercococcyx consists almost exclusively of 
caterpillars. 
637. Cuculus gabonensis. [Za-so-foe, or Mon-Obam.] 
Sharpe, Ibis, 1907, p. 436. 
The note published in a previous paper Ibis/ 1907, 
p. 435) about the call-notes of the common Cuckoo of this 
country should, I suppose, have been under this name and 
not “ Cuculus solitarius.” Its characteristic call of tc Za-so- 
foe ” seems to fit exactly the descriptions which I have read 
of the call of the South-African “ Piet-mij myrow.” The 
other loud excited call described in my former note I have 
since watched a bird make while it chased another (probably 
its mate) from branch to branch of a tree. 
A hen bird (No. 1901) had an egg in the oviduct just 
ready to be laid, which got broken before it could be taken 
out. It was not larger than the egg of Pycnonotusgabonensis , 
if as large. 
[Judging from the fragments, I should say the egg appears 
to have been of a somewhat pointed oval form and almost 
devoid of gloss. The ground-colour is white, sparingly 
marked, chiefly at the large end, with small spots and dots of 
a dull purplish brown and lilac-grey.—O.-G.] 
651. Indicator stictithorax. [Mali.] 
Sharpe, Ibis, 1907, p. 440. 
All my four specimens of this bird were obtained on 
my collecting-trip to the heavily forested region near the 
coast in September 1906. They were shot in the tree-tops
