CHERRIE: ORNITHOLOGY OF THE ORINOCO REGION. 229 
On my first expedition to the Orinoco region a single specimen 
of this species was collected at Quiribana de Caicara^ but was not 
included in Berlepsch and Hartert's paper. In 1905 an adult male and 
an adult female were taken at Ciudad Bolivar. April 3rd.

This and the preceding species occur together throughout the 
middle stretches of the Orinoco. Specimens were collected at Ciudad 
Bolivar, Agua Salada de Ciudad Bolivar, Caicara and Quiribana de Cai- 
cara. A nest and set of eggs were taken at Quiribana ile Caicara 
April i6th. 1898, and described in the Berlepsch and Hartert paper.

Common, noted at various points along the river from Caicara 
down as far as Las Barrancas in the delta region. Only two speci- 
mens of this species were taken on my first expedition to the 
Orinoco. One of the two collected at that time, together with a 
nest and set of eggs, was taken on the 2nd of April. Both the nest 
and the eggs resemble those of other species of Elaenia that have 
come under my observation, except that the nest-lining used by E. 
cristata and the present species is composed of the soft, silky hair- 
like fibres covering the seeds from the silk cotton tree, whereas 
feathers are usually employed. 
Specimens from Caicara and from Las Barrancas have been com- 
pared with the type of Elaenia albiventris- in the collection of the 
American Museum and found to be identical.
