REMARKS. There is but one specimen in the collection; in the 
section (Planesticus) which this species comes under, the sexes do 
not differ. 
In the distribution of colors on the under plumage, it is much like 
T. albiventris, but the color of the breast and sides is darker, and 
the upper plumage is of a much deeper and richer brown. The 
strong black bill is a striking feature. 
Mr. Ober says: “ Not abundant; obtained in Rutland Vale, Janu- 
ary 25, 1878.”

The upper plumage is black; the front, lores, and sides of the 
head for a short distance under the eye, are intense black; the 
crown, occiput, hind neck and ear coverts are deep black ; the upper 
part of the back is not quite so deep in color, as it has a slight 
smoky tinge ; the lower part of the back, rump, and upper tail-cov- 
erts have a wash of dull olivaceous, the latter terminate with black ; 
the ear-coverts have their shafts narrowly streaked with white, less 
striking than in JZ. genibardis ; the lower eyelid is pure white ; the 
chin and the anterior part of the rictal stripe are white, the posterior 
part of the latter is cinnamon-red; a very distinct black moustachial 
line starts from the under mandible, and joins the black of the side 
of the neck, separating the rictal stripe from the bright cinnamon- 
red color of the throat; the breast and upper part of the abdomen 
are of a clear plumbeous gray; the middle and lower part of the 
abdomen and the under tail-coverts are of a rather paler cinnamon- 
red than the throat ; the thighs are blackish plumbeous, some of the 
feathers ending with light-red ; the quills are black, the edge of the 
wing and bases of the quill-feathers are white ; the tail-feathers, 
except the outer two, are brownish slate-color, marked transversely 
with black bars, which are not very conspicuous ; the first lateral 
feather has the inner web grayish-white, with a blackish diagonal 
mark at the base, the outer web is black for one quarter of its length 
from the base, the remaining part of a dusky ash-color ; the second 
feather is blackish, except that it has for half its length, on the inner 
web, an elongated white mark along the shaft, widening out to the
