The headword is a masculine noun (see LSJ s.v. o)/xqos, and cf. omicron 1051), here in the accusative plural, evidently quoted from somewhere.
[1] The headword is identically glossed in the Synagoge, Photius' Lexicon (omicron745 Theodoridis), and Lexica Segueriana 323.23. The first gloss is a neuter noun in the (nominative, vocative, and) accusative plural; see LSJ s.v. u(/yos, -eos, to/. The second gloss -- odd in this context -- consists of a masculine noun and adjective in the accusative plural.
[2] An approximation of Dionysius of Halicarnassus, Roman Antiquities 9.15.4. In 479 BCE, Marcus Fabius Vibulanus (consul 483 and 480, d. 477) together with his brother Kaeso Fabius Vibulanus (consul 484, 481, and 479; d. 477; cf. mu 690 n. 2) erected a hilltop garrison near the Cremera River (Barrington Atlas map 43 grid B2) and led a Fabian clan military campaign against the nearby Etruscan city of Veii (in the present-day community of Isola Farnese, Rome, Italy; Barrington Atlas map 43 grid B1); cf. pi 1277 and Smith, p. 934. [In her critical appratus Adler notes that ms F omitted this quotation; also that ms V reads o)/xqoio tino\s a)po\ to/pou, at a place away upon a certain hill.]
