70 AFRICAN LONG-TAILED NIGHT-JAR. 
this band commences in the inner web of the first, 
and terminates on the outer web of the sixth quill ; 
the remaining quills are varied with black and 
rufous, and tipt with white. The tail is variegated 
in the usual manner, the middle pair having about 
twenty very slender transverse bars, but much un- 
dulated, while the outer margin of the exterior

the other measurements have been already given.

scribed as a native of Western Africa. Our present
