160 CAPITONID^ TKICHOL^MA 



Genus II. TRICHOLJEMA. 



Type. 

 Tricholsema, J. & E. Verr. Journ. Ornith. 1885, 



p. 132 T. hirsutum. 



Edge of the upper mandible distinctly toothed (except in T. 

 affinis) ; culmen rounded between the nostrils and curved from base 

 to tip ; chin angle with a few scattered bristles ; breast feathers with 

 shafts produced into long hair-like tips ; wings, feet, and tail as in 

 Lybius ; plumage always with yellow spots. 



This genus, containing twelve recognised species, is confined 

 to Africa ; of the two found in South Africa, T. affinis is not 

 improbably merely the young of the T. leucomelas.
