brown a little extended on each side the shaft. 
Back and wing coverts, with the central part of 
each feather, hair, inclining to clove brown, the 
margin all around being pure white ; the greater 
coverts and secondaries are barred with hair 
brown. The greater quills have their tips, to the 
extent of nearly two inches, deep hair brown nar- 
rowly margined with white ; the exterior circles 
barred with brown, the interior with imperfect 
bars, or, as in the first and second quills, with a 
narrow list of brown along the side of the shaft. 
The tail is white, except the two central feathers, 
which are barred with brown ; the bars on the 
exterior web, imperfect, or not reaching the edge 
of the feathers. The outermost tail feather on 
each side is nearly half an inch shorter than the 
rest. The breast and abdomen are white, each 
feather having the shaft and a portion on each 
side of it hair brown, forming guttiform spots, 
which decrease in size from the breast down- 
wards. The breast, the thighs, and under tail 
coverts, are immaculate white. The bill is of a 
pale bluish gray, the tooth in the upper man- 
dible, and the notch in the lower, both strongly 
developed. Legs and feet bluish gray. From the 
manner in which the skin has been taken off 
and preserved, the correct dimensions cannot be 
ascertained.*
