Two Bogota skins of this small Tyrant are in Sclater’s collection, 
one having been purchased from Bell of New York in 1856, and the 
second more recently obtained from the Maison Verreaux. 
The species is of about the same size and general appearance as 7’. 
cinereiceps, Scl., but wants the conspicuous black ear-coverts and the 
broad whitish spots on the wing-coverts which distinguish that spe- 
cies. It is likewise of a much paler yellow below. The wings 
are rather long and pointed, the second, third, and fourth primaries 
being nearly equal and longest.

pectore flavidiore et pileo nigricantiore, ut videtur, diversus. 
The first specimen of this Tyranniscus which occurred to us was 
obtained near Merida by Mr. Goering *, but we did not venture to de- 
scribe it from a single specimen. More recently in Mr. C, Wyatt’s 
collection we found a second example, which was obtained by that 
gentleman in the Sierra Ocafia.
