of the Juvenal plumage appear. This plumage is similar to the adult 
plumage. At about the same time that the pin-feathers begin to appear, 
the young commence to creep out to the entrance to their burrows, 
where they sprawl in the sun and await the visits of the parents with 
foofl. If alarmed, they will scuttle backwards into the burrow. ne\er 
turning around to dive in head foremost. 
The bottom of the cavities, in nests containing half grown young, 
are alive with maggots working in the excrement and cast off parts of 
the insect food — chiefly small beetles — brought to the young. 
The two nests referred to above, as found on the 8th of Mav, were 
both situated on for in) the practically level sandy 'Soil of the open 
savanna. In each, the excavation was in an almost straight line back 
from the entrance, descending at an angle of about 30" with the hori- 
zontal. In one case the entrance txmnel was 200 cm. long and the 
nest cavity 50 cm. from the surface, in the other the entrance tunnel 
was 135 cm. long and the nest cavity 35 cm. from the surface. 
GALBULIDAE— THE JACAMARS. 
Berlepsch and Hartert's paper records five species onlv, two of 
which were met with on the Orinoco proper, the other three being re- 
corded from Caura River points. An additional species from the upper 
Orinoco is now recorded. 
I believe that without exception the members of this family are 
resident wherever found.
