316 BROOKLYN INSTITUTE MUSEUM. SCIENCE BULLETIN 2. 6. 



The native name Hervidor 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 bubbling, boiling water. 



These cuckoos are occasionally seen in a state of semi-domesti- 

 cation about the native houses. 



CAPITOXIDAE THE BARBETS OR THICKHEADS. 

 Two races of a single species are known from the Orinoco region. 



CAPITO AURATUS INTERMEDIUS Berlepscli & Hartert. 

 Capita auratus intermedius Berlepsch & Hartert, Novit. Zool. IX. 1902. 



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. 



CAPITO AURATUS AURANTIICINCTUS Dalmas. 

 Capita aurantiicinctus Dalmas, Bull. Soc. Zool. France. 1900. p. 178 



("Dans le bassin de la riviere Caura"). 

 Capita auratus aurantiicmctus 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 Andre at Nicare 

 on the same river. 



RAMPHASTIDAE THE TOUCANS. 



Nine species are embraced in the Berlepsch and Hartert paper, but 

 only 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 heavily forested 

 regions beyond the falls of Maipures.
