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.
