and between 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 directly over my head, high up in the tree tops ; in a 

 moment I heard it off to my right, then to my left ; first on this side, 

 then on 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 canopy 

 of leaves far above me. The calls were most tantalizing and my
