4. Genus Barijatula. 
Characteristics. — Rictal bristles black, strongly dcvc;! oped ; culmen acutf; ; boili rniajrliblcH 
evenly sloped towards the tip. Plumage, which is soft and loose, black, marked with yellow. 
Wings moderate; quills exteriorly edged with yellow. Tail very short. Tarsus ratlier 
longer than the exterior front toe with claw; inner hind toe very small. Tiny fc(;d f;ri 
berries, insects, or larvae; they run up and down the trees, like the Piculets, in s(;arc}i of 
insects in the crevices of the bark. They occasionally sit upon the top branches of the 
highest trees uttering their ringing note for hours together ; they nestle in holes in trees, 
and lay six white eggs. 
There are eight species in this genus; all inhabit Africa; and all arc small, except B. 
leucotis, which is as large as a Gyrtmohicco, to which it is distinctly allied, but not so closely 
as it is to Barhatula; after careful examination of the specimen we obtained from the 
Leiden Museum, we have considered it best to classify it with this genus, as the bill is no 
doubt an exaggerated Barhatula bill, the pecuharity of the bristles of Gymnohucco precludes 
our adding it to that genus.

5. Genus Psilopogon. 
Characteristics.— with margin smooth ; a thick bunch of bristles behind each nostril, 
I which are scarlet, with the basal half black ; a band of black across the centre of the bill. 
General plumage green. The tail is longer in proportion than in any other genus of this 
subfamily. 
There is only one known species, which was discovered by MuUer, one of the scientific 
travellers of the Leiden Museum. The distinguishing feature is the bristles, which are in 
two bunches, and differ in form and colouring from those of all the other MegalcBmincE. 
It is found in the dense forests of Sumatra, and, being very locally distributed, has 
been seldom procured.
