(icneral notes. The crown of A. goldmani is much paler than the rest of 

 the back and in the silky gray gloss and pattern of markings closelj r re 

 sembles the crown of a gray specimen of Nyctidromus albicoUis. It has the 

 same general type of coloration as A. ridgwayi, and like it has feathers 

 only on the upper third of the tarsus. Both A. ridgwayi and A. goldmani 

 are very distinct from A. salvin. The latter, although having a very 

 narrow buffy collar around the neck, is a much darker bird with a very 

 different pattern of markings, especially on the wings, and has the upper 

 two-thirds of the tarsus feathered.
