LÖNNBERG AND RENDAHL, ORNITHOLOGY OF ECUADOR. 45 



however, concealed. (It is especially noteworthy that there 

 are no mesial dark spöts or streaks to be seen on the back.) 

 Top of head like the back, in some specimens with scattered 

 small white spöts. Lesser and middle wing-coverts dark 

 brown like the back in some specimens only slightly ticked 

 and spotted with buff, in others more extensively mottled 

 with the same. Primary coverts as a rule uniformly dark 

 brown sometimes feebly dotted with buffish brown. Greater 

 coverts more mottled with greyish biiff and in some specimens 

 also irregularly spotted with buffish white or påle buff. ]\Iargin 

 of wing at base of alula buffish white. Primaries dark brown, 

 outer web with squarish spöts or mottlings of buffish, and 

 some transverse spöts of buffish white on the basal parts of 

 the inner web. Secondaries similar, but the transverse påle 

 markings of the outer web are less solid and consist chiefly 

 of mottlings; the inner web has more or less confluent indenta- 

 tions or bars of buffish white, in some specimens only on the 

 basal parts in others över the greater part of the same. Upper 

 tail-coverts similar to back. Tail-feathers dark brown mottled 

 with greyish buff, more finely towards the edges of both 

 webs, but with a tendency to form spöts or bars on either side 

 of the shaft, sometimes alternating sometimes in pairs. These 

 central markings are almost absent on the proximal portion 

 of the central tail-feathers. Bristly tips to feathers of face 

 very strongly developed and black. Face blackish more or 

 less barred with whitish. Feathers of superciliary region 

 basally white, distally black more or less barred mth white. 

 Auricular region black, narrowly transversely banded with 

 white. Feathers constituting the lower part of the facial ruff 

 extensively white with black tips, thus a white semicollar 

 bordered with black is formed. The white appears to be 

 broader in some males. Chest and upper breast sooty brown 

 with buffish mottlings and white spöts on both webs. The 

 size and number of these spöts is variable in different speci- 

 mens. The ground-colour of the lower breast and abdomen 

 is buff, somewhat varying in intensity. — Thus the general 

 colour of the anterior and posterior portions of the under parts 

 is decidedly different. — The feathers of the lower breast and 

 abdomen are provided with dark brown shaft stripes of varying 

 breadth. On the posterior part of the abdomen and crissum 

 these stripes become less distinct and partly disappear. In
