Aechmolophus

(syn. Xenotriccus Ϯ Pileated Flycatcher X. mexicanus) Gr. αιχμη aikhmē  spear; λοφος lophos  crest; "A NEW GENUS AND SPECIES OF MEXICAN FLYCATCHER   ...   It was originally identified as Myiochanes richardsonii and is labeled as that form. I discovered it in a tray of Empidonax trailli.  Actually the bird has no close relationship to either of these genera, nor does it appear to be referable to any other genus of the Tyrannidae.   ...   Aechmolophus new genus  Small Tyrannidae (wing about 70 mm.) related to Xenotriccus but differing by having the bill flatter, the rictal bristles shorter, the crest decidedly longer, the outer (tenth) primary longer (shorter than the second but longer than the first), the ninth also longer, and the tail slightly shorter than the wing and much less strongly rounded than in Xenotriccus.   ...   Feathering on top of head with acute tips, forming a greatly elongated crest, the longest feathers of which spring from the posterior part of the forehead and reach the anterior part of the mantle; feathering of point of chin, lores, and post-nasal region strongly bristly.   ...   Aechmolophus mexicanus new species   ...   The general appearance of Aechmolophus mexicanus is so plain and lacking in distinctive pattern that at first glance it might be confuised with one of various small and dull-colored members of the family Tyrannidae.  The extremely long and pointed crest, however, at once marks the bird as unusual and a closer examination reveals the combination of characters that prevents association with any of the known genera."
