657. Melignomon zenkeri. 
No. 2181. $. Bitye, Jan. 19, 1907. Stomach con¬ 
taining a mass of fine flakes of wax, mixed with tiny black 
particles. 
695. Gymnobucco bonapartii. [Ovol.] 
Beich. V. A. ii. p. 139. 
Heliobucco bonapartei Sharpe, Ibis, 1907, p. 441. 
Several nestlings have been brought to me at different 
times, caught in their holes in decayed trees. These young 
birds always have the bill dull yellow at the base, and 
blackish at the tip—quite different from the uniform horn- 
colour of the adult. Besides that the feathers of the forehead, 
that become stiff and yellowish in adults, are soft and dark 
in the younger birds. 
Nine individuals, taken by my boys from one colony, were 
shown to me on the 1st of April—five adults and four young 
* of different ages. The boys had stopped up the holes the 
evening before, when the birds were inside and not alert 
enough to fly away, and had chopped the dead tree down 
in the morning. It was in one of the holes of this colony 
that the young Indicator was caught (see above, p. 16). 
Besides the birds, they brought a single egg that was found 
in one of the holes. It measured 22 x 18 mm. 
[An egg of this species is of a perfect oval shape, devoid 
of gloss and pure white.—O.-G.] 
694. Gymnobucco peli. [Ovol.] 
Sharpe, Ibis, 1907, p. 441; Beich. V. A. ii. p. 138. 
I wish to give briefly my reasons for believing that there 
are really two species, G. peli with nasal tufts, and G. calvus 
without them, and that the one is not merely the young or 
immature form of the other. 
Though I found the two forms in the same locality at 
Efulen, as Dr. Sharpe has noted (‘ Ibis/ 1904, p. 616), I 
have found only the one with tufts at the Ja, and there 
I have found it of all ages. 
Young birds of this species, like those of Heliobucco , have 
the bill yellowish at the base and blackish at the tip ; and
