LITTLE RED-BILLED HAWK. 123 



uniform grey ; from whence the ground colour of 

 the body and thighs becomes white, elegantly crossed 

 by narrow and well defined bands of pure grey, 

 broadest on the flanks and body, and narrow on the 

 thighs and belly; the vent and under tail-covers 

 only are dingy white. The tips of all the quills 

 have a conspicuous white margin. The inner webs 

 of the quills, on their upper surface, are nearly of 

 the same dark brown as the outer webs, : a very 

 unusual circumstance in this family, and they are 

 crossed by distinct blackish bands, which do not 

 run into each other ; of these there are seven on 

 the first quill and nine on the next ; the colour of 

 the quills beneath is light brown, becoming nearly 

 white at their base, and the inner wing-covers are 

 banded precisely like the body. The ground co- 

 lour of the tail is light brown, which changes almost 

 to pure white on the outermost feathers, all of 

 which are crossed by four very broad bars (includ- 

 ing that near the tip), which are more distinctly 

 seen on the under than on the upper surface, where 

 the ground colour of all appears to be dingy white. 

 The cere, with the basal half of the bill, together with 

 the legs, are of a bright red ; the other half of the bill 

 and the claws are bluish-black. The outer tail-feather 

 only, on es&fln. side, is shorter than the others. 



The measurement of the only specimen sent is as 

 follows : Total length about 12 inches ; bill, from 

 the gape, ^ ; wings, 6 T 7 ^ ; tail (beyond), 3^ ; from 

 the base, 5| ; tarsus, l-j 8 ^ ; middle toe, without the 

 claw, 1 T V
