96 REVIEW OF AMERICAN BIRDS. [PART I. 



Although the genus Heleodytes is not represented within the 

 region covered by tlie 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 Campylorhynchi 

 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 othei*. 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, Spix. 



Campylorhynchus, Spix, Av. Bras. I, 1824, 77. (Type C. scolopacens, 

 Spix = Turdus varieyatus, 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 throughout. Wings and tail about 

 equal, the latter graduated ; the exterior webs of lateral feathers broad. 'In 

 size the largest of the family.

 of 1st primary, 1.35, of 2d, 2.15, of longest, fourth (measured from exposed 

 base of 1st primary), 2.45; length of bill from forehead, 1.16, from nostril,
