and beU\een the inner row and the edge of the acrotarsium there is a 
narrow strip of non-scutellate membrane. 
The outer toe is longer than the inner one. without claw it 
reaches to the middle of the subterminal phalanx of the middle toe : 
inner toe, without claw, reaches to just beyond the base of the subtermi- 
nal phalanx of the middle toe. Entire basal phalanx of middle toe united 
to outer toe, and about one-fourth its length to the inner toe. 
In Knipolegus the acrotarsium extends entirely across the outside 
and around on to the back of the tarsus, except at the upper end where 
the posterior outer half is occupied by three irregularly quadrate scutella. 
On the inside the acrotarsium extends about half way across at the 
upper end and almost completely across at the lower end. (In dried 
skins the two edges of the acrotarsium usually meet!) The heel is 
covered with roundish papillae, but the remaining integument between 
the edges of the acrotarsium is non-scutellate. 
The outer and middle toes are united at the base for the length of 
the basal phalanx of the outer toe. The inner and middle toes are cleft 
almost to the base.

the dense forest where it frequents the lower branches of the larger 
trees. 
I shall always remember with pleasure what a thrill of expectancy 
shot through me when I first heard the clear ringing call of this bird. 
I was in the dark thick gomales forest (rubber trees) following an 
Indian trail when I was startled by a loud metallic whistle that seemed 
to come from directl)' over my head, high up in the tree tops: in a 
moment I heard it ofif to my right, then to my left ; first on this side, 
then (in that. Then other clarion calls came from the dense forest 
all about me, some near, others only faintly heard in the distance. 
The almost death-like stillness that seemed to pervade the twilight 
quietude of the forest had suddenly been broken and the air rever- 
berated with high-pitched, long-drawn whistling calls. It was a new 
call to me, one that sent the blood coursing with expectancy. I 
stepped cautiously forward peering intently into the thick canojiy 
of leaves far above me. The calls were most tantalizing and my
