JACAMARS. 105 
curved bill, hooked at the tip in the genus Bucco (1537-44), and thickly 
beset with bristles. There is no aftershaft to the contour-feathers. 
They inhabit the dense forests, and are said to resemble Bee-eaters or 
Flycatchers in their habits, most of the insects on which they feed being 
captured on the wing. Very little is known of the nesting-habits, but 
the Swallow-wing (Chelidoptera tenebrosa) (1582) is known to breed 
in holes in banks and lay white eggs. More than forty species are 
recognised and grouped into seveu genera, and representatives of four 
of these are exhibited in the Case. 
Family VI. GatButipm, JAcAMARS. 
The distribution of this family, like that of the nearly allied Bucco- 
nide, is Central and South American. In general appearance they 
resemble the Bee-eaters. The bill is long, slender and pointed, the 
plumage often metallic, and the contour-feathers have an aftershaft. 
The feet are zygodactylous, and in the genus Jacamaralcyon (1854) the 
hind toe is absent. Their habits and mode of feeding are very similar 
to those of the Puff-birds, but the Jacamars more often frequent the 
outskirts of forests in the neighbourhood of streams. They nest in 
holes in banks, and possibly in holes in stumps, and lay white eggs. 
About twenty species are known, belonging to six genera, all of which 
will be found represented. All belong to the subfamily Galbuline except 
the Great Jacamar (Jacamerops grandis) (1586), which, on account of 
its curved bill and other structural characters, is placed in a second 
subfamily, Jacameroperine. 
Order XX1IX. HURYLAIMIFORMES. 
The members of this Order appear to form a connecting-link between 
the Picarian birds and the Passeres. They resemble the latter in having 
the palate egithognathous and in other anatomical characters, but differ 
in having the deep plantar tendons which serve the toes united by a 
vinculum or band, the hind toe being thus incapable of independent 
action. Only one family is recognised. 
Family Eurytamipa. Broap-BiLts. 
As their name implies, these birds are characterised by their broad 
flat bill. They inhabit the forests of South-eastern Asia and the adjacent 
islands, feeding mostly on insects, or, in some cases, on berries and 
fruits, and leading a quiet inactive existence. The nest---a large oval 
structure, composed of grass, moss, and fibres—has an opening at the 
side and is suspended from a thin branch. The eggs are white or
