Several other species, mostly rare or perhaps extra-limital, may yet be ac- 

 corded a place in our North American fauna. 



A number of synonyms for many of the above genera, and even individual 

 species, are so far obsolete that we do not need to recall them at the pres-

 in generic signification, that need be further added here. 



FAMILY XX CAPRIMULGIDAE THE GOAT

The general characters of the family are : Bill very small, 

 depressed, triangular-shaped, somewhat curved, culmen very 

 small but gape immense ; nostrils situated near the base of the 

 bill, round, uncovered, and more or less tubular — that is, 

 raised above the level of the surrounding parts and rounded. 

 Tarsus short, rather weak, and partly feathered above, feet 

 small and weak, very short, the middle toe rather long and all 

 scutellate above, the anterior ones connected with a small web 

 at their base ; wings long and pointed, of ten primaries ; tail 

 rather broad and of ten feathers. "Whole plumage soft, fluffy, 

 and more or less greasy to the touch. The above characters
