“ This bird approaches sufficiently near to the Indian genus 
Tephrodornis, to be classed with it ; the only important struc- 
tural differences being that the acrotarsia are entire and that 
the tail is slightly rounded. The beak resembles that of T. 
Tndica, (Gray) but it is a trifle shorter; the nostrils are concealed 
by incumbent bristly feathers; the fourth, fifth, and sixth quills 
are nearly equal, the first three graduated, and the outer toe 
longer than the inner. 
From Mr. Fraser’s collection.
