 hairs at its base, and black : eyes large : head bluish- 

 white, mixed, as far as the eye, with buff: front buff 

 colour : rump and outer webs of the exterior tail- 

 feathers white : the rest of the plumage full black : 

 tail-feathers little more than one inch and a half 

 long, the two middle ones excepted, which exceed the 

 others by about three inches ; these last are webbed 

 as usual at the base and tips, but the middle part 

 consists of a mere shaft : legs black.
