FAMILY II. LOPHORNID^, 



Or Family of Coquettes. 



Body small, sometimes very minute. Bill slender, short and 

 straight. Head usually crested. Throat, in males very brilliant, 

 in some, the feathers of the sides of throat are very elongated 

 and beautifully spotted, forming a beautiful collar. Tail 

 rounded in some as in the genus Lophornis, In others, the 

 rectrices are of variable forms, sometimes very long, narrow and 

 acute, as in the genus Gouldia, in others, short and acute with 

 the shaft of outermost very long and terminating with a spatula 

 as in the genus Discura. One of the principal characters of 

 the family which is constant for all the species is the white or 

 buff band crossing the rump in both sexes. Sexes unlike.
