Todd-Carriker : Birds of Santa Marta Region, Colombia. 287 



Additional records: Chirua, San Miguel, La Concepcion, San An- 

 tonio (Brown). 



Seven specimens : Fundacion, Pueblo Viejo, and Heights of Chirua. 



The Fundacion specimens differ from the rest, and from a series 

 from Venezuela, in having the cinnamon rufous area on the cap more 

 restricted and more or less overlaid with brown, while the cinnamon 

 rufous of the wings averages paler and less extensive also. Other 

 material in the Carnegie Museum collection indicates the existence of 

 an imperfectly differentiated littoral form possessing these characters 

 in the lower Magdalena Valley. The case will be discussed more fully 

 on another occasion. 



The local distribution of this species is rather peculiar. It was 

 found on the north slope of the Sierra Nevada at from 2,000 to 4,000 

 feet elevation, and in the lowlands only at Fundacion. In the former 

 locality it was taken in the shrubbery and tall grass in the valleys as 

 well as in similar situations on the mountainside. At Fundacion it 

 was encountered in a pasture? near the marsh, where tall weeds 

 abounded. 



239. Synallaxis albescens perpallida Todd. 



Synallaxis albescens perpallida Todd, Proc. Biol. Soc. Washington, XXIX, 

 1916, gj (Rio Hacha; orig. descr. ; type in coll. Carnegie Mus.). — -Apol-

 orig. descr.). 



Eleven specimens : Rio Hacha. 



A small, pale local race of 5'. albescens, known only from the above 

 specimens, and doubtless restricted in its range to the Goajira Penin- 

 sula.' It is markedly whiter below than .S". albescens albigularis, ap- 

 proaching thus 5". albescens hypoleuca of eastern Panama, with the 

 type of which it has been compared. The latter, however, is more 

 rufescent, less grayish on the upper parts, wings, and tail ; the cin- 

 namon rufous of the pileum and wing-coverts is deeper and more 

 extensive; and the forehead is brown, like the back, instead of gray. 

 Specimens from Margarita Island differ still more, so that the form 

 seems well worthy of recognition. 



This bird was fairly common on the salty flats along the lower 

 reaches of the Rio Hacha, where various shrubs and weeds abound.
