82 BANGS NEW SANTA MARTA BIRDS T P ^ E ^ C • 



Smith collections having been made, as pointed out by Dr. Allen, 

 in rather different regions, Mr. Brown working for the most part 

 high up in the mountains, and Mr. Smith mostly at low altitudes. 

 Under each species described here I give a reference to Dr. 

 Allen's Santa Marta paper, where all records for the region can 

 be found. 



Nyctidromus albicollis gilvus subsp. nov. 



Nyctidromus albicollis (Gmel.), Allen, Bull. Amer. Mus. Nat. Hist., Vol. 

 XIII, p. 137- 



Type, from Santa Marta, Colombia, J adult, no. 5201, coll. of E. A. and O. 

 Bangs, collected Jan. 5, 1898, by W. W. Brown, Jr. 



The Santa Marta Parauque is one of the palest of the races of 

 this wide-spread, variable bird, being exceeded in general pallor 

 of coloration only by N. albicollis merrilli Senn. of Texas. It is, 

 however, much smaller than that bird, and the male has the usual 

 amount of white on the outer tail feathers. From the small, dark 

 rufous true N. albicollis of Cayenne, on the one hand, and from the 

 dark, dusky, heavily striped and banded Central American race, 

 on the other, the Santa Marta bird, although occupying an inter- 

 mediate position, is very different. 



The general color of the upper parts [is pale grayish (as in N. a. merrilli) 

 and the back is, comparatively speaking, but little mottled with darker brown, 

 the pale markings of the feathers are deeper yellow (about pale ochraceous in 

 the new form, buff in N. a. merrilli) ; the tail and wings are darker than in 

 N. a. merrilli, but not as dark as in Central American examples ; the under 

 parts are pale yellowish brown (pale ochraceous buff), darker and grayer on 

 breast ; the belly, sides and under tail coverts are nearly clear ochraceous buff, 

 the dusky cross markings, so conspicuous in Central American specimens, 

 being very narrow, much broken, and very pale in color — the under parts 

 being less decidedly barred even than in N. a. merrilli.
