Todd-Carriker: Birds of Santa Mart a Region, Colombia. 219 



a series, despite the fact that occasional specimens are hard to place 

 considered alone. Individual variation is considerable in this species, 

 and due allowance must be made therefor in making comparisons. 



The Central American bird, as represented in our collection by a 

 series from Costa Rica, obviously cannot be referred to true albicollis, 

 although resembling the latter in its relatively heavily barred under 

 parts, by which token it differs also from gilnts. In the rufous phase 

 it seems to be merely a little paler above than albicollis or gilvus, but 

 in the gray phase it is decidedly different from both, being more rufes- 

 cent, less grayish above, while the black streaks on the middle of the 

 pileum and back are wider, and the under parts average less rufescent. 

 It would be unwise to name tins form, however, until the status of 

 certain of the Mexican races lately described can be reinvestigated. 



The present race appears not to be strictly confined to the Santa 

 Marta region, but to extend along the coast to the westward, as far as 

 the Rio Sinu at least, and up the Magdalena Valley for an unknown 

 distance. Specimens from the interior of Colombia, referred to typical 

 albicollis by Dr. Chapman in the absence of material for comparison, 

 certainly do not belong to that form, judging by the few specimens ex- 

 amined in this connection, and probably represent another unnamed 

 race. 



A common bird over the whole of the littoral Tropical Zone, except 

 in the heavy forest itself. It frequents thickets, shrubbery, and dense 

 second-growth by day, always roosting on the ground. Its call is not 

 unlike that of the Poor-will. Mr. Smith sent in two sets of eggs, of 

 two each, collected respectively at Bonda on April 15, and at Don 

 Diego on May 15. The latter set was found in a shady place in a 

 coffee-orchard, on alluvial land, near sea-level. " The eggs are oval 

 to elongate-oval, the ground-color vinaceous buff, irregularly blotched 

 and clouded with a darker shade of buff, interspersed with faint shades 

 of lavender. Some of the eggs are much more heavily marked than 

 others, in one there being a few superimposed streaks of pale hazel. In 

 each set one of the eggs is much less strongly colored than the other." 

 There are in the Carnegie Museum series two young birds in juvenal 

 dress, collected at Bonda on June 26 and 27.
