J. HE Harelds differ from the Garrots in having 

 a shorter and more acute beak, and the tail-feathers 

 being greatly elongated : the nostrils are much more 

 linear, and the crown of the head more elevated. 

 From the Pochards they are readily distinguished by 

 the same character. There is but one species as yet 

 ascertained, which is a native of the northern regions, 

 and subsists on molluscous animals.
