Mr. G. N. Lawrence on Muscipeta incanescens. 497 
XLVII.— Note on Muscipeta incanescens, Wied. 
By George N. Lawrence. 
During my investigation of certain doubtful species of Tyrant- 
birds I examined the type of M. incanescens, Wied, in the 
American Museum of Natural History, in the city of New 
York. Much to my surprise I found it to be of a very dif¬ 
ferent form from Ornithion obsoletum, 0. pusillum, and the 
bird from Mexico described by Mr. Sclater under the name 
of Camptostoma imberbe, which last he considers to be identical 
with M. incanescens, and places it in the genus Ornithion (see 
P.Z. S. 1873, p. 577). 
As M. incanescens proves to be of quite a different genus, 
and C. imberbe clearly belongs to the genus Ornithion (as 
stated by Mr. Sclater), his title must be reinstated, and the 
species called Ornithion imberbe, Scl. 
M. incanescens, Wied, is greyish olive above, with the 
centres of the crown-feathers inconspicuously dull reddish 
brown; lores and a space behind the eye greyish white ; under 
plumage greyish white, with just a perceptible tinge of fulvous 
on the breast and abdomen; wing-coverts and quills rather 
light brown, the middle and greater coverts and the secon¬ 
daries ending with whitish ; tail-feathers light brown, like the 
wings, the outer web of the outer feather paler; bill wide 
and of a blackish brown colour, lighter at the base of under 
mandible, it is furnished with rictal bristles, which are quite 
long though, rather slender; bend of the wing and under 
wing-coverts white with a scarcely perceptible tinge of yel¬ 
low ; tarsi and toes hazel-brown. 
Wing 2 t V inches, tail 2, tarsus T 9 ¥ , bill from front -f T , 
width of bill j\. 
In general appearance it mucb resembles some species of 
Ornithion ; but the bill differs greatly : viewed from above it 
is precisely of the form of the bill of my specimen of Myiobius 
putcher, not differing in length and width; but it is rather 
higher, and a side view of it is much like that of an Ornithion; 
Andes, the last-mentioned bird extending its range from Guiana to the 
eastern slopes of the same mountains.
