 inner webs of the shorter ones ; rectrices sooty black, with very 

 narrow whitish edges to the tips and longitudinal whitish spots 

 near the bases. Total length about 5 inches, wing 4-7, tail 1-7,

Easily distingiiished from M. andicoln by the sooty-black hind 

 neck and concolorous rump. In coloration it resembles more 

 Aeronnutes melanoleucMS, but is much smaller and the colour of the 

 lower parts much different. The toes seem to be quite unfeathered, 

 and therefore it is a true Micropus.
