454 Annals of the Carnegie Museum. 



Twenty-four specimens: Bonda, Minca, Don Diego, Mamatoco, La 

 Tig^era, Las Vegas, and Cincinnati. 



With a much larger series of specimens than were available at the 

 time this form was discriminated (Annals Carnegie Museum, VIII, 

 1 91 2, 204) its characters are fully confirmed. While there are of 

 course occasional examples which are quite indistinguishable from 

 typical pitiayumi, as claimed by Messrs. Hellmayr and von Seilern 

 (Archiv fur Naturgeschichte, LXXVIII, 1912, 46) the general dif- 

 ferences are apparent at a glance when series are compared. Males 

 are usually, although not always, more richly colored than females, but 

 there seems to be little if any seasonal variation. 



This dainty little warbler ranges from the lower edge of the foot- 

 hills up to 4,000 feet or more, being rarely seen below 1,000 feet. Its 

 favorite haunts are the forest, open woodland, and especially along 

 the streams in the foothills. In its habits it is a true warbler, always 

 keeping well up near the tops of the trees, for which reason it is 

 easily overlooked, being rather a silent bird. 



430. Ateleodacnis bicolor (Vieiilot). 



Dacnis plumbea Allen, Bull. Am. Mus. Nat. Hist., XIII, 1900, 174 (Santa 

 Marta region). 



Fourteen specimens : Pueblo Viejo and Punto Caiman. 



Sclater's description of the female of this species {Catalogue of 

 the Birds in the British Museum, XI, 1886, 26) really applies to the 

 immature bird of both sexes, as shown by the present fine series, which 

 includes specimens in both juvenal (paler and duller) and first winter 

 (brighter yellow) dress. Adult females resemble the adult males, 

 but are somewhat duller in general coloration. 



Typical Cayenne skins are not available, but Bahia specimens in the 

 collection of the American Museum of Natural History are absolutely 

 indistinguishable from these and other Colombian birds. 



One of the specimens sent in by Mr. Smith is labelled as coming 

 from Pueblo Viejo, near the entrance to the Cienaga Grande. It has 

 not been detected by the writer anywhere except in the mangroves 

 along the shores of the Cienaga Grande at Punto Caiman. Although 

 search was made for it at other points along the mangrove-lined 

 shores of this body of water it was not found. It was one of the 

 commonest birds among the mangroves at the aforesaid locality, and
