iRT. 7 EEVI3I0X OF THE GEIS^US BASILEUTERUS TODD 15 



Some discussion has arisen over the status of specimens from the 

 interior of Colombia. Sharpe ranged skins from " Bogota " under 

 both '"'' uro'pygialis''^ (i. e., fulvicauda) and semicervina. Doctor 

 Chapman, writing in 1917, was unable to settle the status of the 

 Magdalena Valley form of this species because of insufficient mate- 

 rial, but referred all his specimens from the Pacific coast and Antio- 

 quia to semicervina^ while calling a skin from Chicoral fulvivauda. 

 With a good series from El Tambor, in the valley of the Rio Lebrija, 

 available for comparison with another from various localities in 

 western Colombia, I find that taken as a whole the former average 

 somewhat darker in color below than the latter, but this is fully 

 accounted for by their less worn and fresher condition, they having 

 been collected earlier in the season (December and January), while 

 the other series are all in more worn plumage (April to June). They 

 average larger, but not so decidedly as to justify subspecific separa- 

 tion. 



It has been assumed that " Bogota " skins (some of them at least) 

 may have come from the low country east of the Eastern Andes, but 

 until authentic specimens from this part actually come to hand, and 

 turn out to be really fuVvicauda^ I see no reason to place " Bogota " 

 records under that form. At the same time it is possible that a 

 recognizable form may inhabit the upper Magdalena Valley.
