82 BANGS — NEW SANTA MARTA BIRDS gee oe 
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. 
XCM pbs 77 
Type, from Santa Marta, Colombia, @ 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 JV. 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 JV. a/bicollis 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 jis pale grayish (as in WV. a. merrill) 
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 WV. a. merriliz) ; the tail and wings are darker than in 
LV. a. merrilii, 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 JV. a. merrill.
