The Knots have the beaks depressed at the tip, 
and the grooves in which the nostrils are placed are 
very long : the beak is scarcely as long as the head : 
their toes are slightly bordered with a membrane, 
but are not palmated : the feathers of the tail are 
equal in length. There is but one species found in 
Europe.
