 B. rikeri (Ridgway). 



This monotypic genus, which has no very near ally, has a 

 somewhat long and pointed bill, the ridge of the culmen and the 

 keel of the lower mandible narrow, and the feathers at the base of 

 the forehead encroaching on to the posterior ])ortion of the 

 nostrils. The wing is pointed, the second and third primaries 

 longest and equal, the first slightly shorter than the fourth but 

 much longer than the fifth. The tail, which is about four-fifths 

 the length of the wing, is rounded and graduated, tlie feathers aie 

 soft and pointed at the tips. The tarsus is slightly shoitf>r in 

 length than the exposed culmen, the hinder toe and claw about 

 equal in length to that of the middle toe and claw. '
