and tail-coverts, secondaries and tail, margined with yellow ; under 
wing-coverts yellowish white ; irides hazel; bill black; legs deep 
lead-colour. 
This bird is like a Nuthatch in its habits, being capable of not 
only running up the trunk of a tree with great agility, but of de- 
scending also, head downwards, with equal or even more facility, an 
act which the Woodpecker is, I believe, unable to perform. The tail 
is short and very soft, and is not used in climbing. Like our Eu- 
ropean Sitta, the downward position seems the most easy and natural. 
Of the difference of sexes, if any, I am unable to speak, but I have 
reason to believe the young of this genus differ considerably from 
the adult*. The Buccos are stupid and inactive; I have shot three 
or four from the same tree, one after the other, without disturbing 
the rest.

Crown of the head alternately banded with blue and black ; from 
each nostril commences a large patch of rufous, which envelopes the 
base of the lower mandible, ears, and sides of the head, forms a broad 
stripe over the eye, and extends along the sides of the neck and body, 
and also over the under wing-coverts ; the back is ultramarine blue ; 
the upper wing-coverts are tipped, and the wings and tail glossed 
with the same hue; the throat and the centre of the chest and abdo- 
men are white ; bill and feet red. 
* T have in my collection young specimens of a species of Bucco, nearly 
allied to the above, and in which the body is much spotted and barred, as 
we so frequently find it in young birds, and wants the decided colouring 
characteristic of the adults of the present genus. These young birds I feel 
no doubt constitute a new species, but with such imperfect materials I do 
not think it desirable to impose a name. The plumage is very soft and 
loose; the upper parts of the body are of a blackish colour; the crown of 
the head is adorned with numerous small yellow spots, and the feathers of 
the back and rump are margined with yellow, giving a barred appearance 
to these parts; the wing-coverts are narrowly edged with dirty yellow; the 
under parts of the body are pale inclining to white, but as it were irregu- 
larly washed with yellow; the beak is horn-coloured, and the feet are black. 
These young birds were shot on naked isolated trees.
