“ By viewing this as the type of the Scansorial group of the Tyrant-flycatchers, (Tyranninæ) every circumstance, even the most minute, regarding its structure and its colours will be explained. As representing Brachypus, (North. Zool. 2. 485.) and its analogies, it has the under tail covers richly coloured. As representing Leiothryx (Il. 490.) it has the same coloured cinereous and silky plumage: as a scansorial type, it has a conspicuous although an incumbent crest, and a long ornamented tail. It is a Titmouse among the Tyrants, and is nearly as much of a Ceblepyris as of a Tyrannus. ”
