The unglossed headword, presumably extracted from the first quotation given, is an adjective in the neuter nominative/accusative plural.
[1] Greek Anthology 5.13.3-4 (Philodemus). The passage is also quoted under kappa 2277 through e(/sthke. Note that the transmitted peritroma/dos in the present entry is probably incorrect; peridroma/dos (as in Paton, Waltz) is the correct reading. However, the lexicographer was probably correct to write mi/trhs, thus providing a preferable alternative to the direct tradition's mh/trhs (see the apparatus criticus in Waltz p.26).
[2] Greek Anthology 5.194.3-4 (Poseidippus or Asclepiades). The passage is describing a girl named Eirenion; cf. Gow and Page (vol. I, 53), (vol. II, 140), and another extract from this epigram at alpha 4003. This quotation does not use the headword, but rather the noun lu/gdos from which it is derived. Quarried from rich layers on the Aegean island of Paros (Barrington Atlas map 61 grid A4), this white marble (cf. pi 643 and pi 644) was the most famous sculpting stone in antiquity, renowned for its purity and whiteness; cf. Gow and Page (vol. II, 140) and Blümner (31-34).
