and lack the usual white throat. The Sub-family ranges from 
Mexico to South Brazil. 
These birds are usually found towards the outskirts of forests 
near water, where they frequent lofty trees, and commonly sit 
crouched upon some dead or slender branch for hours, merely 
moving the head from time to time. The food consists of in- 
sects—especially flies or moths—which are often caught wpon the 
wing, and crushed against the boughs before they are swallowed, 
the bird sallying forth and returning to its perch like a Fly- 
catcher. The regular note is short and seldom heard; but Jaca- 
maralcyon has, according to the natives, an agreeable whistling 
song. The flight is quick and jerky. Generally found soli- 
tary or in pairs, the various species occasionally bathe in small 
flocks. The three or more roundish white eggs are laid in holes 
in banks, or possibly in old stumps. In some districts names 
equivalent to “ Large Humming-birds” are given to Jacamars ; 
while early writers confounded them with Kingfishers. 
Urogalba paradisea of Guiana, Peru, and Brazil, and JU. 
amazonun. of Upper Amazonia, characterized by an extremely 
long and tapering median pair of tail-feathers, are dark blue, with 
bronzy and green reflexions, brownish heads, and white throats. 
Seven out of ten members of the genus (Galbula are also 
Amazonian ; the remainder reaching South Mexico, Bolivia, and 
South-East Brazil, and one of them Trinidad and Tobago. G. 
albirostris is brilhant bronzy-green above, with rufous lower parts 
and white throat; most of its congeners being fairly similar, though 
G. chalcothoraz has a decided red and blue gloss on both sur- 
faces and a white abdomen. SBrachygalba, which extends from 
Colombia to Amazonia, includes six diminutive forms, with a vary- 
ing admixture of green and brown above, of black, brown, rufous 
and white below. Jacamaralcyon tridactyla of South-East Brazil is 
ereenish-black, with a brown, rufous-streaked head, and a white 
mid-breast and abdomen.  Galbaleyrhynchus leucotis ot Kast 
Ecuador and Upper Amazonia is chestnut, with white cheeks and 
darker head and quills. Jacamerops grandis, ranging from Veragua 
to Amazonia and Ecuador, is bright coppery-green, with blackish 
wings and tail, a white throat-patch, and a chestnut abdomen. 
Sub-fam. 2. Bueconinae.—The Puff-birds differ structurally 
from the Galbulinae only in having shorter and stouter beaks, 
with hooked or incurved tips; stronger metatarsi, which are scaly
