Adult. Upper part of the head black, slightly mottled with rufous 

 brown on the occiput ; throat whitish ; neck with black and rufous 

 1)ars ; back similar, but the bars broader and better defined, the light 

 bars becoming greyish on the lower back, rump, and upper tail- 

 coverts ; upper wing-coverts greyish olive, vermiculated with black,, 

 the greater ones broadly barred with black and rufous grey ; 

 bastard-wing, primary-coverts, and primaries greyish black ; under 

 wing-coverts brown-black, the last row grey, the central ones 

 greyish ; lower fore neck and sides of breast greyish, with dusky 

 vermiculations ; middle of the breast whitish ; flanks buff, with 

 black bars ; under tail-coverts rufescent, with irregular black bars 

 and buff tips ; tail barred with black and rufescent : bill horny 

 black above, paler beneath ; feet in dry skin brown. Total length 

 about 12 inches, wing 7, tail 2'o, culmen I'l, tarsus 2-1. 



The only specimen I have seen of this species is the one collected 

 on the Lower Pilcomayo by Graham Kerr ; D'Azara says he has 

 seen eight specimens in 24° 8. lat., about the same latitude as 

 the Lower Pilcomayo. It apppears to me that the specimen 

 examined is different from the Bolivian and Brazilian birds 

 (C. scoloj)ax=rculiatus). The principal diflerenccs are the much 

 darker colouring, the much broader barrings of the upper parts, the 

 upper part of the head almost entirely black, and the bastard-wing, 

 primary-coverts, and primaries of a much darker greyish brown, 

 nearly black.
