it's point. The sides of the head under the 
eyes are of a blueish grey. The whole upper 
side, from the bill to the tip of the tail, is of a" 
black or dusky brown, no part lighter or darker 
than another, except the crown of the head. 
The covert-feathers within-side of the wings- 
are white, the insides of the quills ash-coloured. 
The under side of the bird, from the throat to 
the coverts beneath the tail inclusive, Is white. 
The tail has twelve feathers, the outer ones 
something shorter than those in the middle. 
The legs are of a flattish make, like those in 
the Colymba kind. The outsides of the legs, 
and the outer toes, are blackish ; the insides of 
the legs, and the remainder of the feet, are of 
a livid flesh- colour. It has only three toes, all 
'forv/ard, webbed together as in Ducks ; the 
outer toe as long as the middle one, the inner 
shorter. The claws are black. It has, arising 
immediately from the heel, without any inter- 
vening toe, a claw or horny nail ; which, with 
the shape of the bill, proves this bird to be of 
the . genus of Petrels. Willughby calls it a 
small back toe, he having no conception of 
,a talon arising from the heel of a bird ; for, 
in his time, this genus of birds was hardly 
known.
