wing feathers on each side enormously extended, so as 
to present a very singular appearance ; another species 
will be observed to have two of the tail feathers 
elongated in the same extravagant fashion, so as to 
have obtained the name of the Lyre-tailed Nightjar. 
A very hawk-like bird, the only member of its family 
(Steatornis caripensis), met with chiefly in Trinidad, is 
known as the Oil-bird; it appears to be a fruit-eater. 
From Australia and New Guinea come the large birds 
of the genus Podargus and Eurostopodus, examples of 
which will be seen. We must pass on to the Rollers 
(Coracias) and Bee-eaters (J/erops), some of which 
are superbly beautiful, and both families send us 
an occasional straggler from the shores of the Medi- 
terranean; the Bee-eater is confined to the Old 
World, but the Rollers inhabit the whole of Africa, 
India, and Australia. 
The second sub-order HALCYONES contains the 
Kingfishers ; the birds of the genus /Za/cyon being 
conspicuous for their beauty, and the great Aus- 
tralian Laughing Jackass (Dacelo gigantea) is pol 
the most grotesque. 
From the Kingfishers we pass to the Motmots, 
inhabitants of Central and South America. Monotus 
braztlienstis may be regarded as the type. ENA 
Case VIII. 
The first shelf of this case 1s devoted to the 
Hornbills, consisting of a single family but nineteen 
genera, containing more than 60 species, conspicuous 
for their unwieldy beak, usually adorned with a remark- 
able excrescence, which gained for them the name of 
“Rhinoceros Avis.” ‘The usual food of the Hornbills 
is fruit and seeds, supplemented by snakes and lizards 
in the case of the larger species, and insects in 
the smaller species.
