[1] Likewise in the Synagoge and in Photius, Lexicon pi752 Theodoridis, similarly in Hesychius pi1854 and in a scholion to Sophocles, Ajax 649; cf. next note. The headword is neuter nominative/accusative singular of the ambiguous adjective periskelh/s: see generally LSJ s.v. A (from the verb ske/llw "dry up") and B (from the noun ske/los "leg", cf. pi 1282). The present glossing ought to indicate that this instance falls under A, though Hesychius (above) adds 'or as far as the feet', which looks like a comment on the periskele/s garment in Leviticus 6.3 LXX. Either way, it must be quoted from somewhere (other than the quotation given, which has the masculine nominative plural); extant possibilities for A include Marcus Aurelius, Meditations 4.28.1.
[2] Sophocles, Ajax 646-652 (web address 1); quoted already in part at alpha 550, alpha 2046, and epsilon 323.
