DEFINITIONS

XENORNIS
(Thamnophilidae; Ϯ Spiny-faced Antshrike X. setifrons) Gr. ξενος xenos  stranger; ορνις ornis, ορνιθος ornithos  bird; "XENORNIS, new genus   GENERIC DIAGNOSIS.—A formicarian bird, possibly a member of the thamnophiline group but without close resemblance to any known species. Bill somewhat as in Erionotus punctatus but more compressed laterally; wing more rounded, the flight feathers more incurved; tail of ten feathers more graduate.   ...   TYPE.— Xenornis setifrons, new species.   ...   Of this bird we have but a single specimen, the relationships of which have long puzzled the members of our department of birds.   ...  While I have suggested the relationships of this species with the thamnophiline group, its incurved wings and loosely barbed rectrices indicate a bird of less active, vigorous habits than most thamnophili.  Possibly it is more closely related to Percnostola, which has incurved wing quills, stiffened frontal feathers, and loosely bared rectrices.  But the tarsi are longer than in Percnostola and the mandible lacks the gonydeal swelling so characteristic of Thamnophilus and its allies and present in Xenornis."
