there is a mark under the eye of the same colour ; the ears, edge of 

 shoulders, thighs and under teil-coverts are also bright yellow ; the 

 space between the eye and the gape is brown ; the bill is black and 

 the legs are flesh-colour.

The upper surface of the head and body is black ; superciliary 

 stripe and one across the forehead, which passes under the eye and 

 along the cheek, and the whole of the under surface, sulphureous ; 

 space between the superciliary and cheek stripes black ; upper wing 

 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 aS'/7^i7, the downward position seems the most easy and natural. 

 Of the difi'erence 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.

* I have in my collection young specimens of a species oi Bucco, nearly 

 allied to the above, and in which the body is nmch 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 nvmierous 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 yellov.- ; 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 yoiuig birds were shot on naked isolated trees.
