96 REVIEW OF AMERICAN BIRDS. [PART I. 
Although the genus Heleodytes is not represented within the 
region covered by the present review, I introduce a brief mention 
of it with the view of completing the history of the family, as well 
as of illustrating the peculiarities of the species of Campylorhyncht 
having very similar nostrils. The relationships between the two 
genera are very close, and it is almost a question whether they can 
be separated trenchantly from each other. The specimen before me, 
from Mr. Lawrence’s collection, is from Bogota; and, as it may be 
different from the species of Guiana and Venezuela, I subjoin a brief 
description. , 
CAMPYLORHYNCHUS, Sprx. 
Campylorhynchus, Sprx, Av. Bras. I, 1824, 77. (Type C. scolopaceus, 
Sprx = Turdus variegatus, GMEL.) 
Bill stout, compressed, as long as, or longer than the head, without notch 
or rictal bristles; culmen and commissure curved; gonys nearly straight. 
Nostrils in the antero-inferior part of nasal groove, in advance of the frontal 
feathers, with an overhanging scale with thickened edge, as in Thryothorus ; 
sometimes, as in the type, reduced to a slight ridge along the upper side of 
the nasal groove. Lateral septum not projecting below or anteriorly into the 
nasal cavity, but concealed by the nasal scale. Tarsus a little longer than 
middle toe and claw; claws strong, much curved, and very sharp; middle 
toe with basal joint adherent almost throughont. Wings and tail about 
equal, the latter graduated ; the exterior webs of lateral feathers broad. In 
size the largest of the family. 
1 Heleodytes griseus. 
Furnarius griseus, Swanson, Anim. in Menag. 1838, 325 (21 Centen. 
No. 134), fig. 67, b (bill), Guiana.— Campylorhynchus griseus, Can. 
Schomburgk, Reise Guiana, III, 1848, 674.—Heleodytes griseus, Cas.

Whole upper parts, including wings and tail; plain brown, without bars 
or other markings, as also a line from behind the eye; the nape and inter- 
scapulum blackish-brown, the top of head lighter, the lower back and rump 
reddish-brown. Entire under parts, including lining of wings, tibia, and a 
broad line from bill over the eye, soiled white. All the tail feathers, except 
the two central, with a broad subterminal bar of white, diminishing in width 
from the outer feathers to the inner, but at the same distance from the tips. 
Total length, 8.50; wing, 3.30; tail, 3.45; graduation, .45; exposed portion 
of Ist primary, 1.35, of 2d, 2.15, of longest, fourth (measured from exposed 
base of Ist primary), 2.45; length of bill from forehead, 1.16, from nostril, 
.66; along gape, 1.26; tarsus, 1.10; middle toe and claw, 1.10; claw alone, 
.30; hind toe and claw, .87; claw alone, .38.
