Galbula ruficauda pallida (lapsus) Allen, Bull. Am. Mus. Nat. Hist., XIII, 



1900, 120, 135 (Cienaga and Bonda) ; XXI, 1905, 280 (Bonda; descr. eggs). 

 Galbula pollens Sharpe, Hand-List Birds, II, 1900, 194 (ref. orig. descr.; 



range). — Beabourne and Chubb, Birds S. Am., I, 1912, 161 (ref. orig. 



descr.; range). 



Additional records: Tierra Nueva (Carriker).. 



Twenty-nine specimens: Bonda, Cienaga, Dibulla, Rio Hacha, Ma- 

 matoco, Fundacion, and Tucurinca. 



In this form the bill (all the measurements, in fact) averages longer 

 than in true ruficauda; there is more buffy tinge on the throat, there 

 is a more decided color-difference between the sexes; and the under 

 parts, posterior to the pectoral band, are noticeably paler, sex for sex. 

 The race was described from this region, but is now known to range 

 over into the lower Magdalena and Sinu Valleys. 



A species characteristic of the littoral Tropical Zone, ranging over 

 the whole of the lowlands, but more abundant in the drier portions, 

 where the woodland is open above and filled with tangled undergrowth 

 below. In its feeding habits it is not unlike the flycatchers, selecting 

 a perch in the open and catching insects on the wing. Many but- 

 terflies are eaten. 



A set of two eggs, collected by Mr. Smith at Bonda on April 17, 

 are described as clear glossy white. Simons says that it "buUds its 

 nest in the banks of streams."
