The native name Hcrvidor is derived from the Spanish verb hervir 
— to boil — doubtless in allusion to the peculiar vocal performance 
which certainly is much like the sound of bubliling, boiling water. 
These cuckoos are occasionall}' seen in a state of semi-domesti- 
cation about the native houses. 
CAPITONIDAE— THE BARBETS OR THICKHEADS. 
Two races of a single species are known from the Orinoco region.

p. 98. {Type, ex Nericagua, upper Orinoco, Venez.). 
Only two specimens, a male and a female, were collected on my 
first expedition, at Nericagua, on the upper Orinoco. 
There is a series in the American Museum collection from Boca de 
Sina, Cunucunuma River (upper Orinoco), that doubtless should be re- 
ferred to this race. They show, however, a considerable orange wash 
on the lower breast and abdomen, a character supposed to be distinctive 
of a. aurantiicinctus. and are scarcely to be distinguished from a couple 
or Caura River specimens. I am consequently doubtful if intermedius 
is a valid race.

("Dans le bassin de la riviere Caura"). 
Capito auratus aurantiicinctus Berlepsch & Hartert, p. 99. 
In the Am. Museum collection are two specimens from La Union 
(Caura River). One shows a considerable amount of the orange color on 
the middle of the breast that is supposed to be distinctive of the race. 
First described and recorded from the Caura River by Dalmas. 
Berlepsch and Hartert record a specimen collected by .\ndre at Nicare 
on the same river. 
RAMPHASTID.XE— THE TOUCANS. 
Nine species are embraced in the Berlepsch and Hartert paper, but 
onlv five were collected by the writer on the Orinoco proper, the remain- 
ing four having been collected by either Klages or Andre at points on 
the Caura River. None were seen until I arrived in the hea\-ily forested 
regions beyond the falls of Maipures.
