Nyctidromus Gould.* 



Bill moderate, with the gape very wide where the lateral margins are dilated, and furnished with long 

 slender bristles ; the culmen curved, and the sides much compressed to the tip, which is hooked and 

 emarginated ; the base of the upper mandible with a few short bristles ; the nostrils lateral, tubular, with 

 the opening large and exposed. Wings moderate, with the third quill the longest. Tail lengthened, and 

 graduated. Tarsi nearly as long as the middle toe, naked, and broadly scutellated in front. Toes
