ON THE GENEEA. 
XXIX 
4. Genus Barbatula. 
Charmteristies .- Kictal bristles black, strongly developed; culmen acute; both mandibles 
evenly sloped towards the tip. Plumage, which is soft and loose, black, marked with yellow, 
"mgs moderate; quills exteriorly edged with yellow. Tail very short. Tarsus rather 
onger than the extenor front toe with claw; inner hind toe very small. They feed on 
ernes, insects, or larva;; they run up and down the trees, like the Piculets, in search of 
insects m the crevices of the bark. They occasionally sit upon the top. branches of the 
lghest 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 are small, except B. 
eucotis, which is as large as a Gymnobucco, to which it is distinctly allied, but not so closely 
as it is to Bar batula ; after careful examination of the specimen we obtained from the 
eiden Museum, we have considered it best to classify it with this genus, as the bill is no 
doubt an exaggerated Barbatula bill, the peculiarity of the bristles of Gymnobucco precludes 
our adding it to that genus.

mveUers of the Leiden Museum. The distinguishing feature is the bristles, which are in
