ZOSTERORNIS. 52T 
Genus ZOSTERORNIS Grant, 1894. 
Bill slender and pointed; rictal bristles small, less than bill from 
nostril; nasal opening oval with a large overhanging membrane; wing 
pointed, not greatly curved, and slightly exceeding the tail; rectrices 
well developed; tarsivand feet slender, and moderate in length; tarsus 
about twice the bill from nostril. Some species in this genus resemble 
species of Mixornis, but in the latter there is no flap above the nasal 
opening and the feathers of the back are long and fluffy. 
“This genus is most nearly allied to Cyanoderma, but there is no naked 
space around the eyes, which, on the contrary, are encircled by a ring of 
short white feathers perfectly similar to that of a true Zosterops. From 
Mizornis it differs in having the nostrils long and covered by a large 
membrane. ‘The tail is composed of twelve feathers. The fifth primary 
is slightly longer than the fourth and sixth; first, short, half the length 
of the second.” (Grant.)
