 Dytes, Kaup. Natiirl. Syst. p. 49 (1829). 



Type D. auritus (Linn.). 



The Horned Grebes have the bill shorter than in the Great 

 Crested Grebes, the length of the bill from the gape being 

 less than that of the inner toe and claw. The form of 

 the bill, too, is stouter and rather more curved at the tip. The 

 tippet, too, is more dense and entirely black, and extends over 

 the entire throat, the feathers of which are full, the black tippet 

 being surmounted by a band of crested plumes along the 

 sides of the crown from the eye, forming a crest.
