Not distinguishable in any way from examples from Venezuela and 

 Trinidad. There is some variation affecting the relative proportions 

 of black and white on the upper parts, as in specimens from these other 

 regions. The. present series includes several young birds, shot in 

 August. 



With practically the same range and habitat as Arundinicola leu- 

 cocephala (except that it was found at Rio Hacha and Dibulla on the 

 north coast), this species is more abundant, haunting the margins of 

 sluggish streams, lagoons, and marshes, and is very tame. * It was 

 breeding in the marsh at Fundacion in August. The nest is a tiny, 

 thin-walled, cup-shaped structure, made of fine grasses and the fibers 

 of wild plantain, interwoven with thorny twigs and lined with vege- 

 table down, and placed in the fork of a small thorny shrub, two feet 

 over the water. Three white eggs are laid.

These average paler yellow below than a series from the interior of 

 Colombia, but the difference is certainly only seasonal. In fresh 

 plumage the wing-bands are more buffy. 35 



3fi Since the above was written Messrs. Hartert and Goodson {Novitates 

 Zoologiccc, XXIV, 19 17, 494) have undertaken to show that the birds of the 

 mountains of Venezuela are subspecifically separable from topotypical setoph- 

 agoides, described from " Bogota." As such a conclusion would naturally 

 leave the status of the Santa Marta birds open to question, we have again gone
